8 Renovation Projects That Almost Never Deliver the Return Sellers Expect in 2026

Every homeowner approaching a sale wants to believe that the money they poured into their home will come back to them at closing. That’s an understandable instinct. Renovations feel tangible, personal, and significant – so the financial logic seems obvious. Spend more, earn more.

Reality is more complicated. The 2026 Cost vs Value Report confirms a trend that has been building for years: small, exterior, curb-appeal projects deliver the best return on investment, and big interior remodels deliver the worst. The projects homeowners tend to be most excited about are often the ones that disappoint them most at resale. Here are eight of the biggest culprits.

1. Upscale Kitchen Overhaul

A full kitchen gut renovation is one of the most emotionally satisfying projects a homeowner can undertake. It’s also one of the most financially sobering. Major high-end kitchen overhauls costing $85,000 to $150,000 or more – covering custom cabinetry, luxury countertops, professional-grade appliances, and structural changes – return only about 38 to 50 percent of their cost. You’re spending $85,000 to add roughly $32,000 to $42,500 in home value, which is only justified if you’re staying long-term and prioritizing personal enjoyment over resale.

Many homebuyers want a kitchen they can live with until they can afford a more extensive remodel. Indeed, the more complex the project, the lower the return on investment at the time of house sale. The contrast with a more modest refresh is stark. A major upscale kitchen remodel can cost $80,000 to $150,000 or more, so even a large value increase translates into roughly 40 percent ROI. A minor midrange kitchen remodel, by contrast, returns about 96 percent because it costs far less while still modernizing the space.

2. Luxury Primary Suite Addition

Adding or expanding a high-end primary suite seems like an obvious win. More space, better privacy, a luxurious retreat – what buyer wouldn’t want that? The cost of a luxury primary suite addition runs $100,000 to $300,000 or more for a high-quality project, far exceeding what most markets will reward. Buyers price homes relative to the neighborhood, and a luxury addition in a mid-range market often appraises below its cost.

Adding a primary suite is an example of a major renovation that usually doesn’t give you a good return on investment, typically returning only 24 to 36 percent. These projects are better for personal enjoyment than resale value. The mismatch between what sellers feel the space is worth and what appraisers will actually credit is consistently wide on this type of project.

3. In-Ground Swimming Pool

Nothing signals summer living quite like a backyard pool. The sales pitch practically writes itself. The financial reality, though, is consistently grim for most sellers. While a pool can increase a home’s price, the increase is usually not enough to cover the cost of building and maintaining it. Inground pools tend to perform better than above-ground pools, but they still underperform many other home upgrades in terms of resale value. Appraisals rarely credit pools dollar for dollar, and in many markets a pool can actually make a home harder to sell by shrinking the buyer pool.

The ROI on installation cost is typically 40 to 60 percent – meaning a $60,000 inground pool usually adds $24,000 to $36,000 in home value, not the full $60,000. Pools rarely pay back installation dollar-for-dollar. They cost $50,000 to $80,000, and outside of hot-climate markets like Arizona and South Florida, many buyers see a pool as a maintenance, insurance, and safety liability rather than an asset. Unless pools are expected in your neighborhood, skip it if you plan to sell within five years.

4. Sunroom Addition

Sunrooms are genuinely appealing spaces – bright, relaxed, versatile. Sellers often expect buyers to recognize that appeal and pay for it. On a national level, sunroom additions typically recoup approximately 49 to 55 percent of their project cost at resale. That means a $40,000 sunroom investment can add roughly $20,000 to $28,000 to your property’s appraised value. That’s a meaningful gap between what was spent and what comes back.

Sunrooms are beautiful and livable, but they’re expensive to build and don’t always count as true square footage. In colder areas, sunrooms can’t be used year-round, so while it may be a nice feature, it’s not as much of a must-have as in hotter climates, and the resale value will reflect that. The ROI range is also wide – a full addition sunroom can recoup around 50 to 70 percent at resale, four-season rooms come in next at approximately 50 to 60 percent, while three-season rooms and screen rooms typically offer a lower ROI ranging from 30 to 50 percent and 20 to 40 percent respectively.

5. Upscale Bathroom Remodel

A spa-like bathroom with heated floors, frameless glass showers, and freestanding soaking tubs is genuinely pleasurable to live with. Selling it to the market at full cost is another matter. The return on investment for high-end bathroom renovations costing $29,200 or more is less than 50 percent. This trend holds true for all types of projects: moderate investments do better than high-end ones.

The same pattern holds for bathrooms. A minor bathroom update – new vanity, fixtures, lighting, paint, and re-caulk – returns about 71 percent. A high-end primary bath addition returns far less. The lesson the 2026 report keeps teaching: refresh, don’t gut, if resale is the goal. Buyers acknowledge a nice bathroom, but they rarely pay a premium that reflects the full cost of a luxury renovation.

6. Home Office Conversion

After a sustained period of remote and hybrid work, homeowners assumed that purpose-built home offices would be a major selling point. The numbers suggest otherwise. The lowest-ROI projects include high-end home office conversions, which return about 28 percent. That figure is particularly striking given how much sellers expect buyers to value a dedicated workspace in 2026.

Part of the problem is permanence. A fully converted room – with built-in shelving, custom cabinetry, soundproofing, and specialty lighting – appeals to one specific type of buyer. Families needing a bedroom, couples wanting a guest room, or buyers who work in an office see a dedicated home office as something they’d need to undo. ROI varies significantly by geographic market, neighborhood, and the current state of your home before renovations, but a highly specialized conversion rarely translates broadly enough to justify the build cost at resale.

7. Backup Power Generator

Whole-home backup generators have surged in popularity following high-profile power outages and grid reliability concerns. Sellers who install them often expect buyers to recognize and reward that preparedness. The 2025 Cost vs Value data tells a different story. The installation of solar panels on the roof was poorly valued by real-estate professionals and delivered the second lowest return on investment on a national basis, and backup generators face similar skepticism from appraisers, who treat them as conveniences rather than structural value.

ROI for backup power generators shows a variation of 70 points across regions, which means performance is wildly inconsistent. In storm-prone coastal areas or regions with frequent outages, a generator may carry real appeal. In stable-grid suburban markets, most buyers simply won’t pay a meaningful premium for it. The cost of installation versus the appraised value added leaves most sellers disappointed at closing.

Solar panels are appealing for all the right reasons: lower utility bills, reduced environmental impact, energy independence. The lifestyle case is solid. The resale case is considerably shakier. Solar panels delivered the second lowest return on investment on a national basis among new projects tracked in the 2025 Cost vs Value Report. Regionally, ROIs were highest in the Pacific at about 41 percent and East South Central regions at about 35 percent, and lowest in New England at about 25 percent.

Ultra-luxury upgrades and major square-footage additions rarely recoup costs at resale, and solar follows the same logic: the upfront cost is substantial, and buyers don’t always trust that the system will continue to perform or that their utility savings projections will hold. Leased solar systems compound the problem further, sometimes creating financing complications that slow or complicate the sale entirely. Sellers who install solar for their own benefit during a long ownership period can come out ahead overall, but those installing shortly before listing rarely do.

The through-line across all eight of these projects is the gap between what a renovation feels worth and what the market actually credits. The 2026 Cost vs Value Report keeps delivering the same message: spend small, spend on the exterior, and refresh rather than gut. Renovating for your own comfort over years of ownership is a legitimate and reasonable choice. Renovating specifically to recoup money at the closing table requires a harder look at the data before the first nail is driven.
