Short answer: Home improvements that don’t add value when you sell include a new in-ground pool, a garage turned into a bedroom, a bedroom given up for a walk-in closet or office, marble floors and high-end fixtures. What buyers pay for is a home they can move straight into.
Most sellers fix something before they list: 78% made at least one improvement, according to Zillow’s 2026 Consumer Housing Trends Report. Some projects earn their cost back. Others cost you twice: once to build and again when buyers will not pay for them.
Projects that rarely pay off before a sale
- A new in-ground pool. Expensive to build and to keep, and many buyers see upkeep, not a perk.
- Turning the garage into a bedroom. Plenty of buyers want the parking and storage back.
- Giving up a bedroom for a walk-in closet or a home office. Zillow found homes with walk-in closets sold for about 0.5% less.
- Marble floors. Zillow found they were linked to a sale price nearly 2% lower. Travertine was linked to about a 1.2% boost instead.
- High-end fixtures and a dedicated media room. Buyers rarely pay back the premium.
- DIY work that looks like DIY. An inspector will find it, and buyers will price it in.

What buyers do pay for
Zillow’s 2026 research on listing words found move-in ready homes sold for about 3% more than expected and remodeled homes about 2% more (Zillow). In plain terms: fix what is broken, paint, clean, and let buyers see a home they can move straight into.
On Staten Island those percentages are real money. At the October 2026 median sale of $800,000, 3% is about $24,000 and 2% is about $16,000. The same 2% lost to marble floors is about $16,000 too.
- Repairs an inspection would flag: leaks, cracked tiles, loose railings, old smoke alarms.
- Fresh, neutral paint where walls are scuffed or dark.
- A tidy front: trimmed shrubs, a clean walk, a front door that looks cared for.
- Bright lighting in every room for the photos.
