August CPI, Rates, and iBuyers: What Moves Housing

What pros wish everyone knew about CPI, mortgages, and iBuyers

Here’s the thing that trips people up every single August CPI week: CPI doesn’t set home prices. Rates do. The CPI print nudges rate expectations, rates change monthly payments, and payments decide who can actually bid. That’s the chain. Ask any loan officer fielding panicked texts after a hot CPI, buyers don’t say “inflation rose 0.x%,” they say “did my payment just jump?”

Quick sanity check. Shelter is the elephant in the CPI room, about one-third of the headline basket in 2025 (roughly 34% per BLS). But Shelter CPI is laggy; it reflects lease renewals signed months ago, sometimes close to a year. Real-world asking rents move first, and the CPI shelter component drifts in after. So, yes, the August print matters for bonds, but it’s not a live read on your local open house in Phoenix this weekend.

What will you actually get from this section? Three clean connections, minus the hype:

• CPI → rates → payments → demand: a 0.25% swing in mortgage rates changes the monthly payment on a $400,000 loan by about $65-$75, which is just enough to knock a borderline buyer off or on the fence.
• Shelter CPI lags: we’ll separate what the index says from what new leases and asking prices are doing right now. If you’ve heard me say “owners’ equivalent rent” and your eyes glazed, fine, that’s the technical term; practically, it’s a slow filter on fast-moving rents.
• iBuyers run on spread and speed: they make money on disciplined purchase discounts, tight reno budgets, and fast turns, not on wishing prices go up.

And a piece most folks miss, volatility. Not just the level of rates. iBuyer unit economics can live with a 7% mortgage world (around 7% this summer, give or take, per Freddie Mac’s PMMS). What kills them is whipsaw: when the 10-year moves hard day-to-day, pricing models blow out, days-on-market stretch, and funding lines get pricier right when you need them cheap. Lower vol lets them quote tighter spreads and turn inventory faster.

I’ll connect the dots to what an August CPI surprise typically does in today’s market. If CPI comes in hotter, the knee-jerk is higher yields, higher mortgage rates, higher payments, softer demand. Cooler print, opposite story. But keep the lag in your head: Shelter CPI is late to the party, while rent asking data and purchase mortgage rate sheets update basically in real-time. That difference is where investors and operators, especially iBuyers, either make money or get steamrolled.

Bottom line: the headline matters for bonds; payments matter for buyers; volatility matters for iBuyers. We’ll show how those three interact in Q4 without the sugarcoat.

So, did August 2025 CPI actually help mortgage rates?

Short answer: a bit, but the mechanism isn’t the one most headlines talk about. Traders live in the weeds of core and so-called “supercore” (core services ex-housing). Why? Because that’s where sticky momentum hides. A single cool month can tilt odds on the Fed path and nudge the 10‑year; a single hot month can do the opposite. But the move that matters for your borrower quote is the combo of Treasury yields plus MBS spreads plus volatility. Miss any one of those and you’ll mis-read rate sheets by 0.125%-0.25%, easy.

Quick framing before we answer the question properly. The headline CPI print grabs attention, but mortgage desks translate it through two pipes:

• Pipe 1: Treasuries. The 10‑year is the anchor. A 10 bp move in the 10‑year typically maps to roughly 3-5 bp in 30‑year mortgage rates if MBS spreads stand still. That’s a rule of thumb, not gospel, I’ve seen it be 2 bp on calm days and 7 bp when convexity hedging kicks in.
• Pipe 2: MBS spreads. Current‑coupon agency MBS normally trade at a spread of roughly 150-180 bps to the 10‑year in 2024 data, widening in stress and tightening when vol cools. Tighten spreads 10-15 bps and you can shave ~0.05%-0.10% off borrower rates even if the 10‑year doesn’t budge.

Now the content of CPI. Core CPI carries the signal. Shelter is a huge share, about 34% of headline CPI and roughly 43% of core CPI in 2024 per BLS weight tables, so when you hear “core,” a big chunk is housing. Here’s the catch: shelter CPI famously lags private rent indexes by 9-12 months (Cleveland Fed research in 2022-2023 shows that lag pretty clearly). Which means lenders and RE operators react to market rents and rate sheets now, while the official shelter line catches up later. Timing mismatch, and it matters.

So did the August report help? It helped to the extent it kept rate volatility contained. Traders care a lot about the trend in 3- and 6‑month annualized core and supercore. If those showed momentum cooling toward the low‑2s % annualized, markets usually read that as “the disinflation trend is intact,” which reduces the tails on the Fed path. Lower tails = lower vol. And lower vol lets mortgage desks tighten pricing. I’ve literally watched lock desks squeeze 8-12 bps tighter in midday reprice simply because implied rate vol cooled, even on a flat 10‑year. It feels silly; it’s not. Funding and pipeline hedging get cheaper when the MOVE index drops, and that saving shows up in borrower quotes.

Two extra bits I don’t want to oversell but they’re real:

• Traders watch the trend, not the dot. One 0.2% m/m in supercore doesn’t win the war if the 3‑month annualized is still running hot. Same the other way. Intellectual humility helps: one data point can be noise.
• Lenders reprice faster than shelter CPI adjusts. Apartment asking rents rolled over last year; shelter CPI will reflect that on a lag. Rate sheets, by contrast, move intraday. That’s why you can see better mortgage pricing ahead of any visible improvement in the official shelter line, almost backwards timing, but that’s the machine.

Where does this leave Q4 rate sheets? If August CPI reinforced disinflation, again, specifically in core and supercore, then you get two positives for mortgages: modest downward pressure on the 10‑year and tighter MBS spreads via calmer vol. Even if the 10‑year level barely changed, a 10 bp tightening in the MBS basis can feel like a 0.05% rate win on a 30‑year fixed. If the report came in sticky, you still might not see a huge rate blowout, but bid/ask widens and lock desks pad cushions; borrowers feel that as choppy, less predictable quotes.

Translation: CPI didn’t “solve” mortgage rates. It either trimmed the risk premium by lowering volatility or it didn’t. Lenders price the trend and the variance, not the vibes.

One last sanity check. Yes, Freddie Mac’s PMMS is useful, but it’s a weekly average and lags the MBS tape by a few days. Intraday, a 15-20 bp swing in current‑coupon OAS can come and go before PMMS even prints. That’s why a calm CPI day can quietly help borrowers even when the headlines say “little change.” I’ve been burned by assuming the headline told the whole story, won’t make that mistake twice.

From CPI to your payment: the mechanics that actually move housing

Here’s the plumbing as it actually happens in Q4 2025. CPI comes out, rate-cut or cut-deferral odds shift, and the 2s-10s curve jiggles. The 10-year Treasury is the anchor for 30-year fixed mortgages because that’s the duration proxy investors use. On top of that, you’ve got mortgage-backed securities (MBS) spreads and a credit box. When the current-coupon MBS OAS widens, lenders can’t eat it, they push it through to rate sheets. When it tightens, you sometimes see a friendlier print, sometimes not, because lock desks are managing pipeline hedges and margin risk at the same time.

Mechanically, mortgage rates = 10-year Treasury yield + MBS spread + lender margin/LLPAs/servicing value + hedging and capital costs. In quiet markets, that add-on can look like ~150-200 bps over 10s. In noisy weeks, that wedge can balloon by 25-50 bps for the same 10-year level because volatility raises the price of optionality. Convexity and prepayment risk are the culprits, when rates fall, loans refi and bond duration shortens; when rates rise, duration extends. That asymmetry forces originators and servicers to hedge more, and hedging costs aren’t free.

The kicker: lenders price both level and variance. If CPI comes in as expected but rate vol jumps, lock desks widen their cushions. Bid/ask in the TBA stack moves, and yes, you’ll feel it as a higher note rate or wonkier pricing. I’ve sat on calls where nothing “macro” changed, yet the hedging budget did, quotes got worse within hours. It’s not vibes; it’s VAR.

Quick translation: Mortgage rates track 10s first, then MBS spreads, then lender margin/hedge costs. Vol up = fatter spreads and margins. Vol down = tighter. Simple, but also…not simple.

Affordability happens in the monthly payment, not the list price headline. A 25-50 bp swing can decide whether a buyer passes DTI. Example math on a $400,000 loan, 30-year fixed principal & interest only: at 7.00%, the payment is about $2,661; at 6.75%, ~$2,594; at 6.50%, ~$2,528. That’s ~$67 per month per 25 bps on this balance. Scale that up or down and it’s the same story, DTI thresholds are math, not macro takes.

For sellers, buyer power is basically payment power. If CPI cools and rate vol compresses, you don’t necessarily get a big price spike, you get a few more qualified buyers who can actually clear underwriting. That can tighten days-on-market or reduce concessions even if list prices don’t jump right away. The payment math leads, prices follow with a lag. Always been that way.

On refis, don’t expect a tidal wave unless rate drops are meaningful. Small dips mostly produce cash‑out and debt consolidation, not pure rate-and-term. Homeowners with 2020-2021 vintages aren’t rolling a 3-handle into a 6-handle because CPI cooled a touch, no way. You typically need at least ~75-100 bps of net rate savings, after costs, for a broad-based refi wave to pencil. Sub-50 bp dips usually unlock niche pockets: paying off credit cards, finishing a kitchen, or consolidating personal loans. That’s what we’re seeing this year, incremental activity, not a surge.

A quick note on lender behavior in volatile weeks: margins and LLPAs widen, extension fees edge up, and renegotiation policies get stingier. Pipeline managers care about fallout risk; if CPI stirs the curve and prepay assumptions get jumpy, hedge ratios get bumped and rate sheets wear it. I know it’s annoying, but they’d rather eat a day of lower lock volume than a month of hedge slippage.

Bottom line for 2025’s fall market: CPI shapes the odds for the Fed path, the curve translates that into a 10-year anchor, MBS spreads and convexity do the heavy lifting, and lenders convert all of that into the rate you see. If you’re timing a purchase, watch the 10-year and current-coupon MBS basis first, headlines second. And if your DTI is tight, a 0.25% rate move isn’t small; it’s the whole ballgame.

iBuyers in 2025: can an August CPI tailwind widen spreads again?

Operationally this is pretty simple, even if it doesn’t feel simple when you’re trying to price 200 offers before lunch. iBuyers live on three levers: buy cheap enough, sell fast enough, and finance the gap cheap enough. When August CPI cooled rate volatility this year, it didn’t magically lower 30-year mortgage rates by a full point, but it did something almost as important for this model, buyers showed up with more confidence, and days-on-market tightened a touch. That means fewer price cuts, smaller acquisition discounts required to hit hurdle IRRs, and better hit rates on offers because the buy box can move closer to fair value without blowing up.

Quick sanity math, because this is where people get lost and I don’t blame you: on a $400k purchase financed on a warehouse/ABS blend at, say, an all-in 7% annual carry, each day costs roughly $76 in interest alone (400,000 x 0.07 / 365). Add taxes, insurance, utilities, HOA, and light turns, call it another $25-$40 per day depending on the market, and every 10 days saved is ~$1,000-$1,200 back in margin. If August’s calmer tape trims DOM by even 7-10 days versus early summer, you can see why acquisition discount targets inch tighter by 50-100 bps without raising risk, the carry math lets you.

Now, lower volatility can help tighten bid-ask, but funding costs don’t just follow CPI headlines. Warehouse pricing and term ABS coupons move with broader credit conditions: dealer balance sheets, IG/consumer ABS spreads, and risk appetite. In risk-off weeks last year, we saw consumer ABS option-adjusted spreads gap wider by 20-40 bps week-over-week, your cost of funds picks that up fast, even if CPI is friendly. So an August tailwind helps on turn time and confidence, while the true cost-of-capital piece still answers to credit beta, not the CPI line item.

Two practical implications I’m seeing on desks this fall:

• Lower vol → smaller required discounts. When rate sheets aren’t whipsawing, resale pricing is less jumpy and listing agents resist big concessions a little less, so iBuyers can win more bids with a 3-5% discount to comp instead of 5-7% on mid-tier stock. That boosts hit rates, which keeps the machine fed.
• Shorter DOM → lower price risk per flip. Less time exposed to weekend headlines and micro comps means fewer surprise 1-2% price cuts mid-hold. That’s real, not theoretical.

Here’s where I get a bit animated, because it’s the part people gloss over: market depth is wildly local. Phoenix and Atlanta can handle larger weekly supply pulses without blowing spreads, while parts of Austin or Riverside still feel thin at price points above the FHA/VA sweet spot. And Q4 is Q4, seasonal slowdown is undefeated. Open houses thin out, list-to-sale ratios sag, and the sub-$400k tier holds up better than $1m+ because payments rule behavior in a 6-7% rate world. If you’re underwriting a flip in a higher tier right now, you need a bigger cushion or a more aggressive pre-list strategy, or both.

I should also say this before it gets too nerdy, yes, I know this is getting complicated: the August CPI calm didn’t fix capex or turn costs. Labor and materials are still sticky. Even if your capital is 25 bps cheaper and your DOM is 8 days shorter, a $6-$8k average turn on a bread-and-butter resale is still the same check you’re writing. That’s why ops discipline wins fall through winter: tighter scopes, pre-committed vendors, and no science projects.

Rule of thumb: every extra 10 bps in carry on a 60-day hold is roughly 0.17% of sale price on a $400k home. If spreads widen in Q4, that alone can erase the discount you fought to win in acquisition. Keep the pipeline flexible.

Bottom line for iBuyers in Q4 2025: August’s cooler volatility was a help, fewer price gaps and faster turns, but spreads and funding depend on credit, not just CPI, and the seasonal slowdown plus uneven local inventory pockets still write the playbook. Tighten buy boxes, respect DOM by metro and price tier, and don’t count on the tape to bail out sloppy underwriting.

What the housing tape is telling us now

Short version: builders are still doing the heavy lifting with incentives, resale liquidity is a touch better than last year, and investors are picky because Treasuries pay you to be patient. If you felt August CPI leaned the Fed a bit easier, so did the tape. You can see it in rate sheets and in the way days-on-market stopped creeping higher in late August into September. I’m not saying it’s a bull market in housing. I’m saying payment math eased just enough to matter at the margin.

On builders, incentives remain the main lever. Rate buydowns got cheaper as yields softened, remember the math: a permanent 25 bps rate buydown typically prices around 1 point of the loan amount, give or take, while a 2-1 temporary buydown can run ~2-3 points funded by the seller. When the 10-year drifts down even 15-25 bps, the same monthly payment target requires fewer points, so gross margin pressure lightens a hair. Public builder commentary this year has repeatedly pointed to incentive buckets running 4-6% of price in select communities, call it the difference between a stalled buyer and a signed contract. Not universal, but it’s there.

Resale liquidity? Still uneven, but better than last year in a lot of metros because inventory is finally trickling back. Where payment shock eased (even slightly) after the August CPI print, days-on-market stopped lengthening. It’s classic: a $75-$125 lower monthly payment can pull an extra tranche of buyers off the sidelines. It’s not magic; it’s just sensitivity around debt-to-income thresholds. My own inbox from agents in Phoenix and Raleigh showed DOM flattening after mid-August. Could be anecdotal; I’ll caveat that. But it fits the rate tape.

Investors in SFR are doing the same spreadsheet every morning: “What cap rate spread am I getting over the Treasury?” Most institutional mandates I know still want 150-250 bps over the 10-year for stabilized SFR to compensate for turnover and maintenance. If CPI cools, the market leans to lower Treasury yields, and, indirectly, that helps cap rates pencil without sellers taking a bath. It’s indirect because cap rates don’t mechanically tick with CPI, but the discount rate you underwrite against is tethered to the curve, like it or not.

Seasonality matters in Q4. Traffic slows, model homes feel quieter, and pricing power goes local. Builders with tight spec inventory in the Southeast can still hold sticker; infill resales in the Northeast with dated finishes are negotiating. I’ve literally seen two zip codes 15 minutes apart moving in opposite directions this month. That’s why comps feel “wrong”, they are, if you ignore micro-location and product condition.

Buyer tactics are getting more tactical, sorry, redundant but true. Quick locks and float-down options matter if rate chop continues. I like 30-45 day locks with a documented float-down if the note rate improves by at least 25 bps before docs. Small thing, big impact on your stress levels. For builders, pre-funding buydown buckets early in the quarter gives sales teams cleaner pricing language at the table, “we’re buying your rate to X%”, instead of a maze of credits.

Where I get a little excited, yes, me, is the prospect that a slightly easier Fed stance into year-end stabilizes the spread math. Not victory laps, just fewer head-fakes. If that holds, expect: fewer price cuts on the better-located spec homes, mildly faster turns on mid-tier resales, and investors nibbling where cap rates clear policy alternatives.

My take: if the 10-year stays even ~15-30 bps below its early-summer highs, builder buydown costs fall ~0.25-0.50 points on a typical scenario, DOM stays flat-to-down a week vs midsummer in the healthier metros, and SFR bids tighten 25-50 bps where operating lines are locked. It’s marginal, but margins are what pay you.

• Builder incentives remain the key lever; softer yields make those buydowns cheaper.
• Resale liquidity improves when payment shocks ease, even a little.
• SFR investors watch cap-rate vs Treasury spreads; CPI nudges that spread indirectly by moving the curve.
• Q4 seasonality = slower traffic; pricing power is local and uneven.

Your move: practical steps for borrowers, sellers, and investors

Buyers, Two simple things that aren’t actually simple: price cut vs rate buydown, and whether to lock with a float‑down. Get dual lender quotes the same day and ask each for a buydown scenario; then model payments at +/-50 bps on rate because August CPI (headline ran in the low ~3% y/y range, core near ~3% this year) didn’t settle the debate on the path of the 10‑year. Here’s the plain-english math people skip: on a $500k purchase with 20% down (~$400k loan), a $10k price cut lowers payment by roughly $65-$70/month at around 7% rates (rule of thumb: ~$6.65 per $1,000 on a 30‑yr at 7%). A 1‑point permanent buydown (~$4,000 cost) often trims ~25 bps off rate in this market, which on $400k saves in the neighborhood of $60-$80/month and improves break‑even vs the price cut if you’ll hold more than ~3-4 years. Temporary buydowns (2‑1s) can juice year‑1 cash flow but remember they step up; price it like a teaser that needs a refinance or an income step-up to work.

On locking: if your lender has a float‑down feature (many will allow a one‑time reset if rates drop before closing, usually within 30-60 days of funding), that’s cheap optionality. If they don’t, consider a shorter lock and accept the risk since we’re getting fewer head‑fakes but still not out of the woods. And keep in mind what I said earlier: if the 10‑year stays ~15-30 bps below early‑summer highs, builder buydown costs tend to drop ~0.25-0.50 points and DOM in healthier metros runs flat to down about a week (those marginal changes are real money when you stack them with a seller credit.

Sellers ) Prioritize speed‑to‑contract. Q4 traffic is seasonally lighter, so clean listings (pre‑inspection, touch‑ups, photoready day one) win. Price to the most recent pendings, not the closings from last quarter that baked in midsummer rate anxiety; today’s comp set matters more than last quarter’s narrative. If you’ve got an iBuyer in range, treat that like a financing product: certainty has a price. Typical service fees run around 5-7%, you might give up a little on price, but you’re trading for faster cash (often 10-20 day closes) and lower fall‑through risk (in Q4, that time value can offset a chunk of the fee, especially if carrying costs are biting and your next purchase depends on proceeds.

Investors ) Boring but effective: stress test your exits. Underwrite slightly slower absorption (add 7-10 days of DOM vs your base case), and push your cap-rate/credit spreads a touch wider than the rosy scenario. Earlier we talked about SFR bids tightening 25-50 bps where operating lines are locked, don’t pencil that as guaranteed, make it a bonus. If you hold MBS, homebuilder, or mortgage‑REIT exposure, hedge duration and volatility: think of simple rate hedges (pay‑fixed swaps in small size, TBA shorts, or even put spreads on longer-duration ETFs) so you’re not hostage to a curve wobble post‑CPI or a wobbly auction cycle. And check your warehouse/LOC covenants for rate and liquidity triggers; nothing wrecks IRR like forced timing.

Net: model the payment, price to the present tense, and don’t underwrite to best‑case spreads. Boring? Yea. Effective.

One print never makes a cycle

One print never makes a cycle. If August CPI helped cool the temperature, great, take the incremental win and move on. But sustainable housing momentum this year comes from trend inflation easing, steadier rates, and credible liquidity. iBuyers live on speed and predictability; homeowners live on affordability and payment certainty. Different engines, same fuel: cash flow.

Quick reality check on the CPI mechanics: shelter is heavy in the basket. BLS weights put shelter near ~34% of headline CPI and ~43% of core CPI in 2024, so you can’t call the race off one month’s move when the biggest component still lags new‑lease rents by 6-12 months. That lag matters; it’s why the “August print” is a signal, not a verdict. And markets treat it that way, CPI days routinely kick 2‑year yields around by 10-20 bps intraday, which bleeds right into mortgage pricing and TBA spreads. One calm day doesn’t reset term premia or mortgage basis dynamics.

Also worth remembering: rate levels matter, but volatility often matters more for real outcomes. The 30‑year mortgage spread to the 10‑year Treasury averaged about 170 bps from 2015-2019 (pre‑pandemic baseline), versus roughly ~300 bps for much of 2024, a reminder that liquidity, capacity, and convexity hedging keep payments sticky even when the curve nudges your way. In Q4, with holiday season thinning depth, spread chop tends to hang around longer than anyone likes.

So the playbook isn’t heroic. It’s boring, which is kind of the point:

• Treat CPI as a signal: adjust guardrails, don’t rewrite the model. If your base case assumes trend core disinflation, still run a “sticky shelter” scenario where OER takes an extra two quarters to cool.
• Cash flow first: underwrite to a minimum 1.25x-1.35x DSCR on stabilized SFR, and don’t count appreciation in your decision math. Payments pay bills; marks feed egos.
• Liquidity and buffers: 6-9 months of PITI + average monthly capex in cash, and a 10-15% unencumbered liquidity buffer relative to purchase size. Lines are great until they’re not.
• Volatility management > rate calls: small, repeatable hedges (TBA shorts, light pay‑fixed swaps) and staggered locks beat the hero trade. I mis‑timed a lock in 2013, made it back by laddering exits and keeping dry powder, not by predicting the dot plot.
• Optionality: price extensions and alt‑takeout upfront. If you can pivot between bridge-to-term, DSCR, and agency depending on spreads, you’ve built yourself a margin of safety.

On iBuyers, context helps: Redfin reported iBuyers peaked around ~1.7% of U.S. home purchases in 2021 and fell below 0.5% by 2023 as capital tightened and error bars widened. Speed works when pricing bands are tight; uncertainty widens those bands. In 2025, the operators that are humming keep capital costs known, fees transparent, and hold periods short, because volatility tax eats gross margins fast.

For homeowners, it’s simpler. Affordability is the whole game. A tenth lower on CPI is nice; 25-50 bps steadier mortgage pricing over several months is life‑changing. That’s why the focus stays on cash flow, risk controls, and optionality. It’s not flashy. It is repeatable, and repeatable wins compounding. And yes, I know, boring again.

Take the August print as a green light to proceed with caution, not to floor it. The durable wealth path in housing is still the same: cash flow, liquidity, and volatility discipline, with or without a friendly August.

Frequently Asked Questions

Q: How do I handle buying a house when CPI hits and rates jiggle around, am I supposed to time this, or just lock and pray?

A: Short answer: you manage the payment, not the headline. A 0.25% rate swing moves the payment on a $400,000 loan by about $65-$75, which is exactly the difference that knocks borderline buyers on/off the fence. Practical playbook:

• Know your hard payment ceiling before you shop. If your quote at 6.875% works, make sure 7.125% still pencils, or shrink the price target by ~$10k-$15k to keep the payment flat.
• Ask for a lock with a float‑down. You pay a bit more, but if rates ease before closing, you can ratchet down once.
• Compare points to breakeven. Paying 0.5-1.0 points to drop rate ~0.125-0.25% only makes sense if you’ll keep the loan past the breakeven (usually 3-5 years; run the math with your lender’s amortization sheet).
• Keep a backup: if CPI runs hot and rates pop, toggle to a smaller loan, a slightly bigger down payment, or negotiate a seller credit to buy the rate down. I’ve sat through enough CPI Wednesdays to know: perfect timing is luck. A decent lock and a firm payment ceiling is a plan.

Q: What’s the difference between Shelter CPI and what I’m seeing in my actual rent?

A: Shelter CPI is a lagging index; your lease is real‑time(ish). In 2025, shelter is roughly 34% of the CPI basket (per BLS). But CPI’s shelter components, rent of primary residence and owners’ equivalent rent, reflect renewals signed months ago, sometimes close to a year. So August CPI is useful for bonds and rate expectations, but it’s not a live read on your building’s renewal letter. If you want current rent direction, track asking‑rent data from sources like Zillow Observed Rent Index or Apartment List, plus local vacancy and concessions. Translation: CPI explains why rates moved; your landlord explains your payment.

Q: Is it better to sell to an iBuyer or list with an agent while mortgage rates hang around ~7% this year?

A: Depends on your priorities, certainty vs. net proceeds. iBuyers make money on spread and speed: disciplined discounts, tight renos, fast turns. They can live with ~7% rates, but volatility hurts them (when the 10‑year whipsaws, their pricing models widen and offers get more conservative). Your decision tree:

• Need speed/certainty? iBuyer can close fast with fewer showings. Expect a service fee/discount that can total 5-10% all‑in once you include repairs and price spread.
• Want top dollar? Traditional listing usually nets more, but you accept days‑on‑market, repairs, and fall‑through risk.
• Middle paths: get multiple instant offers (not just one), ask for itemized fee/repair estimates, and line up a net sheet vs. a realistic agent CMA. Also consider a bridge loan if timing your next purchase is the bottleneck, or list “as‑is” with a small price concession. Rule I use: if the iBuyer net is within ~1-2% of a realistic agent net, take the certainty. If the gap is 4-6%+, list, unless time is genuinely money for you.

Q: Should I worry about the August CPI print blowing up my mortgage rate this month?

A: Worry? No. Pay attention? Yes. CPI nudges the market’s rate expectations; rates feed straight into your monthly payment. This year, the bigger issue has been volatility, fast moves in the 10‑year Treasury that spill into mortgage pricing intra‑day. Practical moves:

• Lock when the payment works. If you’re inside 30-60 days of closing, ask for a 45-60 day lock or a lock with one‑time float‑down.
• Keep a fallback: have a seller credit ready to buy ~0.25% off the rate if pricing turns after CPI.
• Don’t cut it to the wire. Avoid scheduling rate‑sensitive milestones (appraisal order, CD issuance) for the exact CPI week if you can help it. Net: CPI can shift rates, but your tools, locks, float‑downs, points, or a slightly smaller loan, control the damage.
