12 Things That Can Hurt Your Property Value and Which Ones You Can Fix

Your home is like a bank vault that protects your money. You want it to be solid and secure. Safeguarding your property with some sweat equity can help you get the best price when you sell. But first, you’ll need to know what hurts property value to ensure your investment is safe and sound.

What hurts property value can be things specific to your house — such as deferred maintenance issues, outdated kitchens and bathrooms, or a noisy location — or by outside factors such as your local real estate market or the state of the overall economy. While you can’t take steps to address external forces, you can take action to improve the value of your home.

Not sure where to start? Our top agents do, including Kent Pratt from Missoula, Montana, with 32 years of real estate experience, and Jennifer and Andrew Oldham from Los Gatos, California, who have 23 years of experience to help make your home the gold standard of the housing market. These experts, along with our extensive research, will help you tackle the biggest issues that can hurt your property value.

What hurts property value — 12 factors to consider

1. Deferred or neglected maintenance

Deferred or neglected maintenance is the fastest way to watch your house depreciate. A small drip from your water heater might not seem like a big deal until it leaks into your foundation and causes it to crack. Even if all your systems function today, if they’re not regularly maintained, equipment often breaks and needs to be replaced, which can be expensive.

Going through each part of your home and doing a checkup is one of the best ways to know the health of your home and assess your current situation. The Healthy Homes Maintenance Checklist published by the U.S. Department of Housing and Urban Development (HUD) will help you discover potential problems.

Systems that are damaged or issues that could threaten the entire home should be addressed first, such as:

Old HVAC systems
Termite damage
Decaying wood
Crumbling foundation
Frayed electrical wires
Cracked driveways
Leaky plumbing
Damaged gutters
Missing roof shingles

2. Home improvements done wrong or not built to code

Sometimes doing your own home improvements can save a lot of money, but only if the job is done right. Otherwise, your weekend warrior projects can beat up your wallet if they need to be corrected. Also, if building permits are forgotten, this could result in code violations. Ultimately, this issue could also affect insurance claims such as those that are caused by bad wiring or plumbing. The cost of paying for any fire or flood damage could result in thousands of dollars out of your pocket.

3. Outdated kitchens and bathrooms

If your kitchen looks like it was used in That ‘70s Show, with its original avocado green decor, your buyers probably won’t find it very appetizing.

“Because a buyer isn’t going to necessarily accept a 1970’s range oven just because it works,” says Pratt.

Also, a bathroom that’s entirely pink, including all its fixtures, can be memorable in a bad way.

“You’ll see that a lot in houses where they’ll fix up everything but that one bathroom, and that one bathroom is from 1970, and it looks horrible,” says Andrew Oldham. “But still, even when you look through 30 photographs, all you’re gonna remember is that one bathroom. When a buyer will describe the house to us, they say, ‘Oh, yeah, that’s the one with the pink bathroom.’”

Buyers who aren’t in love with your retro look will be calculating how much it will cost to remodel the kitchen and bathroom to bring them up to date.

If you’re looking to remodel because you’re planning to sell soon, bright, neutral kitchens and bathrooms can help attract buyers, say top real estate agents surveyed by HomeLight.

4. Shoddy workmanship

Mistakes made during the construction of your home or during renovations can affect your property value, especially when it comes to the final appraisal. These errors are often the result of a contractor or DIY homeowner trying to save money or time during a build, renovation, or repair, but shoddy workmanship compromises quality and can reduce the value of your home in the long run.

According to Pratt, each repair can be an added expense the buyer may try to deduct from the list price. “They’ll often look at the functionality of everything, including the kitchen cabinets.”

Buyers who find issues caused by shoddy workmanship will often present a lower offer to offset the money needed to make all the repairs, including items such as:

Tile that is crooked
Warped flooring
Awkward home additions
Uneven decking and railings
Gaps between flooring and walls or thresholds
Inadequate wiring

5. Bad or ugly landscaping

Part of your curb appeal is actually seeing key features of your home from the curb. If your house looks like you’ll need a machete to access the front door, it’s time to take a serious look at your landscaping.

Having a house overtaken by trees, bushes, and weeds is not only unattractive but can also create hazards. Overgrowth can present fire dangers in some regions, or attract bugs and other creatures that could damage your house. Also, ugly landscaping like an unstable dead tree could pose a physical hazard as well.

6. Frail or damaged roof

Having a solid roof over your head protects everything else in your house and can make a big difference in your overall property value. Some signs that your roof could need some attention are physical damage, worn-out shingles, or obvious leaks.

“It’s not uncommon to need a new roof, and that’s one of the big ticket items that the seller has to address whenever they prepare a home for sale. It can be a $2,000 repair to a $40,000 repair. So generally, what we’ll do is get a roof inspection upfront,” Andrew Oldham explains.

7. Noise pollution

Busy off ramps or emergency services such as police, fire, or hospitals that use sirens are considered types of noise pollution. Buyers will generally keep this in mind when they walk through and measure what they can hear inside your house. If it’s too noisy, they may walk away from the purchase or offer less.

8. Registered sex offenders in the area

According to Safehome.org, in 2024, it’s estimated that a total of 795,000 people are listed on sex offender registries. If registered sex offenders live in your area, that can affect your property value, decreasing it due to safety concerns.

9. Neglected houses nearby or “Zombie homes” left vacant or deteriorating

Homes that are seriously neglected — or considered “Zombie homes” because they have been left vacant and deteriorating — can spoil nice neighborhoods. Their dilapidated facades can negatively affect the property value of every other house sitting around them.

“We took a client into a great neighborhood in Carmel [California] to look at this beautiful house they saw on the MLS and all of the listing aggregators. We pulled up and just two houses before that one, it was like the Amityville House. This house had tires, old tractor parts, and it had a dummy doll sitting in a chair. Literally, I got worried. And everywhere around, there were beautiful homes. That poor neighborhood got wrecked from that one house,” says Jennifer Oldham.
