Not every home improvement pays you back. Some actually hurt your return when it’s time to sell. And yet people keep making these upgrades, convinced they’re “investing in the house.” They’re not. They’re just spending money.
To be clear — if a project genuinely makes you happier in your home, go for it. But go in with your eyes open about what you’ll recoup. Here are the worst offenders.
1. Swimming Pool
The big one. An inground pool runs $40,000–$80,000 to install. Typical ROI at resale? About 7%. Not a typo. Spend $50,000, get maybe $3,500 in added value. And some buyers actively avoid pool homes — the maintenance, liability, and insurance implications scare them off.
Speaking of which, your homeowners insurance goes up. Your property taxes go up. The weekly chemical and cleaning costs add up. A pool is a lifestyle decision, not an investment. Know the difference.
2. Over-the-Top Kitchen Remodel
A minor kitchen refresh (new countertops, cabinet refacing, updated hardware, paint) returns about 75–80%. Solid. But a full gut job with commercial appliances, custom cabinetry, and imported tile? Maybe 50–60% back.
Here’s the problem: overcapitalizing. A $90,000 kitchen in a $300,000 house doesn’t make it a $390,000 house. It makes it a $330,000 house with a really nice kitchen. The neighborhood sets the ceiling. Always has.
3. Converting the Garage
Turning a garage into a bedroom, office, or game room sounds practical. But most buyers want a garage. In fact, lack of a garage is a deal-breaker for a huge percentage of them. You gain 400 square feet of living space but lose way more in resale appeal.
Exception: three-car garage and you convert one bay? Minimal impact. Otherwise, don’t.
4. Sunroom Addition
Sunrooms cost $20,000–$80,000 and return about 50% on average. The issue? Many aren’t truly conditioned space — too hot in summer, too cold in winter. And appraisers sometimes don’t even count them in the home’s GLA (gross living area). If it doesn’t count as living space in the appraisal, it barely moves the value needle.
In Florida, where you’d think sunrooms would be a big draw, they’re often just glorified screen porches that don’t factor into square footage. Frustrating for sellers who spent serious money on them.
5. Luxury Bathroom Upgrade
Same story as the kitchen. Basic bathroom update (new vanity, fixtures, tile, fresh paint) returns about 70%. Spa-style renovation with heated floors, frameless glass, freestanding tub? Maybe 40–50%. Buyers appreciate clean and updated. They won’t pay a premium for your marble slab walls.
Keep the upgrade restrained
If you are refreshing a bathroom, spend like a buyer will notice — not like a showroom.A clean vanity, faucet, sink, or shower-door update can make sense. The trap is turning a practical refresh into an overbuilt luxury project the market will not repay.

Custom entertainment centers, whole-house audio, elaborate smart home setups — all depreciating faster than the tech they run on. Today’s cutting-edge is tomorrow’s obsolete. A $15,000 home theater system is worth approximately $0 at resale because the next owner wants their own setup.
Simple smart features? Fine. Thermostat, doorbell camera, smart locks — cheap and universally liked. But don’t go crazy.
7. Removing Bedrooms
Knocking down a wall to turn two small bedrooms into one big one sounds great. But you just reduced your bedroom count, and homes are priced partly by bedrooms. Going from 4-bed to 3-bed can cost $10,000–$30,000 in value depending on the market.
Need more space? Find it somewhere that doesn’t kill your bed count.
8. Elaborate Landscaping
Basic curb appeal (clean mulch, trimmed shrubs, maintained lawn) absolutely adds value. But a $25,000 custom landscape with water features, exotic plants, and hardscaping? You’ll see maybe 15–20% back. And elaborate landscaping requires constant maintenance that intimidates buyers who don’t want the commitment.
9. Wall-to-Wall Carpeting (Over Hardwood)
This used to be common. People actually covered hardwood floors with carpet. If that’s your house — rip it up. There might be gold underneath. But installing new carpet over existing hard floors? You’re spending money to reduce your home’s value. Hard surface flooring is overwhelmingly what today’s buyers want.
What Actually Returns Well
For comparison, here’s what consistently delivers strong ROI: garage door replacement (95%+), minor kitchen refresh (75–80%), manufactured stone veneer (90%+), new entry door (75%), roof replacement (60–70% plus insurance savings), and basic maintenance and repairs that prevent bigger problems down the road.
The pattern is obvious. Maintenance and modest updates pay off. Luxury upgrades and major additions mostly don’t. Spend money on what keeps the house solid. Not on what impresses the neighbors.
