If your home has you down in the dumps but you lack the cash to fix it up, don’t despair! Not every upgrade has to take a big bite out of your bank account.

Here are seven foolproof ways to make your home feel like a totally different place through small changes—and small expenses.

1. New hardware

Swapping out the boring chrome hardware the previous owners installed can go a long way toward making your home look like yours—not to mention give the entire space an easy, inexpensive refresh. Depending on your style, new pulls or handles can cost mere dollars.

“The first thing I do to give the home more of the look and style that I like is swap out the hardware,” says Doug Mahoney, who worked in construction for 10 years and now writes about tools and home improvement for The Sweethome. “All it takes is a screwdriver, and it’s surprising what a difference it can make.”

2. Small paint jobs

Don’t have time to repaint your entire home? Start by tackling smaller jobs such as your front door or kitchen cabinets. Since these projects are quick, you can squeeze them in during the weekend (or even an afternoon). And you’ll use only a fraction of a gallon of paint (which costs between $15 and $30)—making for an ideal impact-to-expenses ratio.

“Personally, I can’t stand the look of polyurethaned oak cabinets, so I’d cover those up with a nice white paint,” Mahoney says. “It makes it look like a whole new kitchen.”

If you like your cabinets, consider repainting the trim in your living room or adding some fresh color to a small room such as your bathroom.

3. Sensor lights

Tired of scrambling for the light switch while your arms are holding bags of groceries? Add sensor lights to your front porch and any other regular entrances such as your garage door. Starting at just $15, it’s a tiny cost with a big reward.

These lights won’t just improve your visibility—they’ll also lower your electricity bill. And they’re a big home safety boon to boot; experts say motion-detecting lights discourage criminals from lurking around your home.

4. Magnetic door catch

Speaking of those arms full of groceries: Adding a magnetic door catch to your primary entrance drastically simplifies loading and unloading. No more awkward sideways crab walks as you attempt to keep the door open while carrying a big package. You might even consider installing this before moving day to make your movers’ job easier.

5. Keyless entry pad

If you’re always losing your keys, try investing in a keyless entry pad such as this simple $100 Kwikset deadbolt. It can mean the difference between spending a few hours moping in your car and enjoying a hot cup of cocoa in your living room.

Plus, you’re not the only one who benefits: If you’re expecting guests but won’t be available to greet them, they can let themselves in—a huge improvement from hiding a key, which might be a safety risk.

6. Low-flow toilet

“It may seem intimidating to those not very interested in DIY, but swapping out toilets is a fairly simple process,” Mahoney says.

Choose a high-efficiency or low-flow toilet to save money on your water bill. While it does require some investment (expect to pay between $100 and $325 for the toilet itself), you’ll be making your money back soon enough—especially if you’re replacing an older model installed before 1992. That’s when federal plumbing standards mandated all toilets use 1.6 gallons or less per flush.

With a high-efficiency model, you’ll use about 300 fewer gallons of water per year—if not much more.

7. Fresh mulch

Jazzing up the outside of your home can go a long way toward making you love where you live. While you could go all-out—landscaping the yard and painting the trim—there’s a simpler solution: mulch.

“New mulch in the flower beds can add a lot to the curb appeal,” Mahoney says.

Instead of grimy old dirt that’s been trod on for years, a fresh new layer looks clean, fresh, and pretty—making a huge difference for just $6.
