The Cost vs. Value of Home Improvement Projects When You Use Your Equity

When you own a home long enough, you build up equity. That’s the part of your house you actually own free and clear, after subtracting what you still owe on your mortgage. Many homeowners consider tapping that equity to pay for home improvements. It makes sense: your house needs a new roof, the kitchen is outdated, or maybe you want to add a deck. Borrowing against your equity can give you the cash to do these projects without using high-interest credit cards. But before you start spending that money, you need to think carefully about which improvements are worth it in the long run. Not every project gives you back what you put in when you eventually sell the house.

The basic idea is simple. When you finance a home improvement with your equity, you are borrowing money that is secured by your home. That means if you cannot repay, you could lose your house. So you want to be sure the project you choose either makes your home safer and more livable, or adds real value that a future buyer would pay extra for. Sometimes a project does both. Sometimes it only gives you personal enjoyment, and you will never see that money again when you sell.

Let’s talk about the improvements that usually give you the best return. Minor kitchen remodels tend to do well. Replacing old appliances with energy-efficient ones, painting cabinets instead of replacing them, putting in new countertops made of quartz or granite—these changes can recover a high percentage of their cost when you sell. The national average return for a minor kitchen remodel is often around 80 to 90 percent. That means if you spend $20,000, you might add $16,000 to $18,000 to your home’s sale price. Not a bad deal, especially since you also get to enjoy a nicer kitchen while you live there.

Another strong candidate is replacing your front door with a steel door, or upgrading your garage door. These are relatively cheap projects. A new steel front door might cost a couple thousand dollars, but it can recover over a hundred percent of its cost because it improves curb appeal and security. Similarly, a new garage door often pays for itself at sale time. Exterior improvements like siding replacement, especially using fiber cement, also tend to have good returns. They make your house look newer and more durable, which buyers notice immediately.

Bathroom remodels can be tricky. A basic update—new toilet, vanity, lighting, and a fresh coat of paint—usually recovers a decent amount. But if you go all out with a luxury spa bathroom, you might not get that money back. Buyers want a clean, functional bathroom, but they rarely pay a premium for high-end tile or a soaking tub that costs thousands extra. Stick to mid-range finishes and professional installation to keep your costs in line with what the market will reward.

Now for the improvements that often disappoint. Adding a swimming pool is one of the biggest money losers. Unless you live in a hot climate where pools are expected, a pool can actually make your house harder to sell. It costs a fortune to maintain, it is a safety hazard for families with young children, and it takes up yard space. Many buyers see a pool as a liability, not an asset. If you build a pool purely for your own enjoyment, understand that you will likely recover only a small fraction of its cost when you sell.

Home offices and sunrooms can also be risky. After the pandemic, many people still work from home, but that doesn’t mean they want a dedicated room that is only an office. Most buyers prefer flexible spaces that can serve as a guest bedroom, playroom, or den. Turning a bedroom into a fancy office with built-in desks and shelving can actually lower your home’s value because you are reducing the number of bedrooms. Similarly, a sunroom might be pleasant, but it often costs much more than the value it adds. Buyers see it as a three-season space that isn’t as useful as a true addition.

Speaking of additions, adding square footage can be valuable, but only if it makes sense for your neighborhood. If every other house on your block has three bedrooms and you add a fourth, you might see a good return. But if you add a huge master suite that is far larger than any other home nearby, your house becomes overimproved for the area. You will have spent a lot of money but won’t be able to sell for enough to cover it. Always look at comparable homes in your neighborhood before you start any big project. The value of an improvement is not just about the project itself—it’s about how it fits into the local market.

Another factor is whether you are doing the work yourself or hiring a contractor. If you have good skills and time, doing the labor yourself can save a lot of money. But be honest about your abilities. A badly done DIY project can lower your home’s value, not raise it. A sloppy tile job, crooked cabinets, or electrical work that isn’t up to code will scare off buyers. Even if you plan to stay in the house for years, shoddy work will eventually become a problem. If you use your home equity to pay for a professional, you are investing in quality that will last.

Finally, remember that using your home equity for improvements means you are increasing the amount you owe on your house. Your monthly payments will go up, either because you are taking out a home equity loan or a line of credit, or because you are refinancing into a larger mortgage. Make sure the improvement you choose will actually increase your home’s value enough to justify that extra payment. Otherwise, you could end up underwater if house prices drop. The best approach is to prioritize projects that improve safety and functionality—like a new roof, HVAC system, or windows—because those are necessary. Then use remaining funds for cosmetic upgrades that give you joy and have a solid chance of paying off later.

In short, not all home improvements are equal. When you borrow against your equity, you are putting your house on the line. So choose projects that either protect your home or add real, marketable value. Do your research, talk to a local real estate agent about what sells in your area, and don’t let excitement over a new pool or a luxury bathroom blind you to the numbers. A smart improvement today can make your home more comfortable now and more profitable later.
