I asked real estate experts what adds value to a home - here's what they said to skip

I'm in love with my house and don't want ever to sell it, but I know the day will come when we retire and will likely want to downsize. So I've started to pay attention to regular maintenance and upgrades that will ultimately add value to my home for when that day comes. You know, adulting.

But it's sometimes hard to figure out what upgrades or home additions actually add value, and which ones don't do anything at all. Or worse, what mistakes we could be making.

So I asked three real estate professionals - Ben Mizes, president of Clever Real Estate; Angie Lopez, a real estate agent in Southern California; and Emiliana Flemate Baker, a real estate agent in Northern California — what actually separates those two outcomes. None of them started with kitchens.

Angie Lopez sees the same pattern over and over: homeowners wait until they're ready to sell, then try to tackle exterior paint, the roof, HVAC, plumbing, and flooring all at once. Her advice is to handle things as they come up instead. She says buyers can feel when a home has been maintained, and it tends to show up during inspections either way.

Ben Mizes put it more bluntly: "The best pre-sale improvement is often the one a future buyer never notices because the homeowner fixed the problem before it became a problem." For him, that means staying ahead of water intrusion, brittle caulking, and drainage issues before they compound.

Emiliana Flemate Baker's take lines up with both; she encourages homeowners to prioritize the systems that protect the home itself, like an aging roof or an inefficient HVAC unit, well before they're thinking about a listing photo.

This was the one all three agreed on.

Angie gave us a surprising tip: spending a lot on something doesn't mean you'll get that money back. She's seen homeowners sink money into upgrades they personally love that the next buyer won't care about at all, so her advice is to keep resale-minded improvements practical and universally appealing rather than very specific and possibly even niche (so I guess this means that you should keep that backyard Tiki Bar idea to yourself!).

Ben says that home value doesn't scale with how much you loved your renovation or your own design. A custom kitchen or patterned tile might be worth it for your own enjoyment, but financially, it's for you, not the sale.

Emiliana has watched this play out with layout changes too, not just finishes. For example, she described a client who added a half bath by carving up space from a primary suite, expecting it to read as a bonus. Buyers saw it as a tradeoff instead. Her rule of thumb: more square footage on a feature list doesn't automatically mean more value.

Ben has found that buyers respond to yard space they can picture actually using, for recreation or grilling, instead of elaborate hardscaping. Simple landscaping, a defined seating area, and consistent upkeep tend to hold value better than an expensive redesign that reads as personalized by the "previous owners".

Keep in mind that something as minor as a leak under a sink or a faint water stain on the ceiling — the kind of thing you may not see as urgent - can turn into drywall damage, warped flooring, or mold, and by the time the home is listed, an inspector is likely to find it anyway.

I saw this recently when a new neighbor moved in and found a huge mold problem that the previous owner had just not controlled.

Angie's rule, in her own words: "When it comes to water, don't wait."

Ben's take that a minor leak can work its way into multiple building systems, and it's always cheaper to fix now than to negotiate later once a buyer has leverage.

Ben's advice: keep every receipt, permit, warranty, and contractor contact, with dates. If you tell a buyer the roof or HVAC is "new" with nothing to back it up, that gap becomes their negotiating leverage.

Emiliana adds a step before any of that paperwork exists - she tells clients to loop in their real estate advisor the moment selling becomes even a five-to-ten-year possibility, not a five-month one. In her experience, a good Realtor can flag which improvements affect marketability and where homeowners risk overspending on something too personal to recoup.

None of this requires a contractor on speed dial or a five-year renovation plan. It just means treating maintenance as part of the home's value instead of something separate from it — because by the time a buyer walks through, they won't know the difference between the two anyway.
