Short answer: cheap exterior replacements beat expensive interior remodels, consistently. Garage doors, entry doors, and siding top every year of the Cost vs. Value report, while major kitchen remodels and primary suite additions recoup roughly a third to half their cost. But the headline percentages are estimates made by surveyed agents, not realized cash, so treat them as a ranking rather than a profit forecast.
Every seller eventually asks a version of this: should I fix the bathroom before I list? Agents get asked it so often that one r/realtors post about building a content system listed "Do I need to fix the bathroom before listing" as one of the twenty questions every agent answers on repeat.
There is real data on this, published annually, and it is widely misquoted. This guide covers what the 2026-cycle numbers actually say, the significant catch buried in how those percentages are calculated, what an appraiser can and cannot give you credit for, and the category of spending that gets left out of every ROI listicle even though agents bring it up constantly.
General information only. Returns vary enormously by market, price point, and the condition of the specific house. Your local agent's read on your street beats any national average.
Zonda's Cost vs. Value Report is the reference here. The 2025 edition, published September 18, 2025, covers 28 projects across 115 US markets, and eight of its top ten projects are exterior work. The pattern has held for years:
| Project | Cost recouped |
|---|---|
| Garage door replacement | 267.7% |
| Steel entry door replacement | 216.4% |
| Manufactured stone veneer | 207.9% |
| Fiber-cement siding replacement | 113.7% |
| Minor kitchen remodel | 112.9% |
| Vinyl siding replacement | 96.5% |
| Backup power generator | 95.3% |
| Wood deck addition | 94.9% |
| Composite deck addition | 88.5% |
| Midrange bath remodel | 80% |
And the other end of the list, where most people's renovation dreams live:
| Project | Cost recouped |
|---|---|
| Basement remodel | 71% |
| Universal design bathroom remodel | 61% |
| Midrange bathroom addition | 53% |
| Backyard patio | 46% |
| Accessory dwelling unit | 41% |
| Solar power installation | 30% |
Major kitchen remodels, upscale bath remodels, and primary suite additions all sit in the declining group, generally recouping somewhere between a third and half their cost. The expensive, exciting projects are the ones that lose the most money at resale.
This is the part that matters, and almost every blog repeating "garage doors return 268%" leaves it out.
The "resale value" side of Cost vs. Value is not sold-price data. It comes from surveying real estate professionals, who estimate what a project would add to a home's price. The cost side comes from Zonda's work with Verisk's XactRemodel estimating software. So the report compares a construction cost estimate against an agent's opinion of value. It is a useful signal about what impresses buyers and agents. It is not a measurement of money that appeared in someone's bank account.
Read literally, 267.7% would mean a $4,500 garage door made you about $12,000. That is not how houses sell. What the number really tells you is that agents consistently rate curb-appeal replacements as having an outsized effect relative to their small cost, and that the effect has grown as buyers have become pickier. Treat the ranking as an ordering of what is worth doing, not as a profit calculator.
A second dataset backs the same ordering from a different angle. The NAR and NARI2025 Remodeling Impact Report, published April 9, 2025, asked contractors about cost recovery and homeowners about satisfaction. Its best recovery figures: a new steel front door at 100%, a closet renovation at 83%, and a fiberglass front door at 80%. New vinyl windows recovered 74% and wood windows 71%. Meanwhile the projects that scored a perfect Joy Score of 10 (a primary bedroom suite addition, a kitchen upgrade, new roofing) are mostly not the ones with the best recovery. The report's own framing is the disparity between the joy of a remodel and what it returns.
The interesting thing about agent discussions is how rarely anyone recommends a remodel. NAR's data says the top projects agents recommend before listing are painting the whole home (50%), painting a single room (41%), and new roofing (37%). Paint, not renovation.
That matches what agents say among themselves. One described the honest list they give clients: if it needs a deep clean, a landscape refresh, weeding and mulch, if it is cluttered or has crappy paint, they say so directly, and they will not take the listing if the seller will not act on it. Another described a seller with an overgrown yard before photos, estimating the mess as roughly a $50,000 ding in curb appeal at that price point. Weeds. Not a kitchen.
The most instructive story in the September 2026 threads involved a completely renovated luxury home that still sat. The agent told the sellers to replace the roof and repaint the exterior for curb appeal. They refused, let the listing expire, then did exactly those two things and relisted with another agent. It sold for what the first agent had predicted. The renovation was already done. The roof and the paint were what moved it.
There is a difference between what a buyer will pay more for and what an appraiser can support, and sellers get burned by the gap.
An appraiser works from comparable sales and makes adjustments for things the market demonstrably pays for: square footage, bedroom and bath count, garage spaces, lot size, overall condition, and age of major systems. Highly personal upgrades often have nowhere to land. An Oklahoma agent put it plainly in an August 2026 thread about an expensive custom closet system: "There isn't a line item on the appraisal for extra, upgraded closet." Their conclusion was that it is a curb-appeal type item, appealing to some buyers, but not actual equity.
This is the practical rule. Improvements that change a measurable category (adding a full bath, finishing permitted square footage, replacing a roof that was at end of life) can show up in an appraisal. Improvements that change taste (a wine fridge, a designer backsplash, a closet build-out) mostly buy you a faster sale and a better first impression, not a higher appraised value. Both are worth something. They are not the same thing, and only one survives an appraisal challenge. If your appraisal does come in low, see How to Challenge a Low Home Appraisal.
Cost vs. Value ranks projects. It does not rank maintenance, because maintenance is not a project. Yet deferred maintenance is what agents complain about most, and what buyers negotiate against hardest.
Nobody pays a premium for a serviced furnace. But an unserviced one, with no records, in a house where the inspector finds three other neglected items, produces a repair request, a credit demand, or a buyer who walks. The return on maintenance shows up as a cost you do not pay, which is why it never appears in an ROI table.
Two things follow from that:
If you are selling within a couple of years, spend in roughly this order:
Notice that a major kitchen remodel is not on this list. If you want a new kitchen, get one, and enjoy it for the years you live there. Just do not tell yourself the buyer is paying for it, because the data says they are paying for about half of it.
The highest-return thing you can do today costs nothing: keep the receipts. Every improvement you make between now and listing day is worth more to a buyer if it is dated, documented, and provable. A roof with an invoice, a warranty, and a permit number is a roof the buyer does not have to guess about. An undated one is a liability in their mental math.
For what to gather before listing, see The Packet and what to document before listing.
Cheap exterior replacements beat expensive interior remodels, consistently and by a wide margin. The headline percentages are agent estimates rather than realized cash, so use them as a ranking, not a promise. Appraisers credit measurable categories, not taste. Paint, cleaning, and landscaping outrank nearly every renovation on the list agents actually give sellers. And the spending that never appears in an ROI report, routine maintenance with documentation behind it, is what keeps your sale from being negotiated down in the first place.
