Renters, Check These 10 Things Before Signing a Lease

When you’re excited about a new place, it’s easy to focus on paint colors and where your couch will go instead of what could go wrong. But a lease is a legal contract, not a wish list, and what you overlook before you sign can cost you money, privacy or peace of mind later. A quick but careful inspection — plus a close read of that paperwork — can save you from surprise leaks, mystery fees or a landlord who disappears when something breaks.

Here are ten things worth checking before you put pen to paper.

1. Read Every Line of the Lease Agreement (Even the Boring Parts)

Before you fall for the place, fall for the paperwork — or at least understand it. The lease spells out everything from how much notice you have to give before moving out to who’s responsible for repairs.

Look for hidden costs like maintenance fees, trash pickup or pet rent. Make sure the lease lists the rent amount, due date and how late fees work. If it mentions anything you didn’t discuss, like extra deposits or required professional carpet cleaning, ask for clarification or a revision before signing.

2. Check the Water Pressure and Temperature

Turn on every faucet, flush every toilet and run the shower. Water pressure that’s too low might mean old, corroded pipes or a shared water line that drops when neighbors use their taps. Wait a moment for hot water, too. If it takes forever to warm up, the water heater might be undersized or struggling. Since landlords typically handle plumbing maintenance, you’ll want any issues addressed before you move in, not after you’ve signed and unpacked.

3. Test the Electrical Outlets and Lighting

Bring a phone charger or small device to test outlets in each room. Flip all the light switches and check that fixtures work and aren’t flickering. If lights dim when the fridge kicks on, the wiring might be overloaded — a fire hazard waiting to happen.

Also, peek at the circuit breaker panel. It should be labeled and easy to access. If it’s rusty or hidden behind furniture, that’s a red flag.

4. Inspect for Water Damage and Mold

Look at ceilings, walls the undersides of sinks for brown stains, bubbling paint or a musty smell. Even a small spot can mean a leak behind the wall or roof issue that hasn’t been fixed properly.

Mold can trigger allergies and respiratory problems, and landlords are typically required to address it. Snap a few photos if you spot anything questionable, and ask what caused it. If you hear “it’s old damage,” make sure the area is fully repaired before you move in.

5. Check Doors, Windows and Locks

Every door and window should open, close and lock smoothly. Loose or broken locks are not just inconvenient — they’re a safety issue. Try the deadbolt and make sure window latches actually catch. While you’re at it, see if windows are drafty or painted shut. You want them to open in case of fire but seal well enough to keep your energy bills from skyrocketing.

Ask the landlord if locks will be rekeyed before you move in. You don’t want the previous tenant — or their dog walker — to still have a spare key.

6. Look at Heating and Cooling Systems

Whether it’s a central HVAC system, a radiator or window units, make sure the system actually works. Turn on the heat and air conditioning, even if it’s not the season. Check air vents for dust buildup and listen for loud rattles that might signal an aging motor. If filters are visibly filthy, it’s a sign the system hasn’t been maintained. Ask when the last service was performed.

7. Take a Walk Around the Exterior

A quick lap outside can tell you a lot. Look at gutters and downspouts — if they’re hanging loose, water may be pooling near the foundation. Check that outdoor lighting works and that walkways are clear and safe. If there’s shared outdoor space, ask who’s responsible for lawn care or snow removal.

And if you’ll have a car, confirm where you can park and whether there are restrictions. Parking disputes are among the top tenant complaints, so get the rules in writing.

8. Test Appliances and Look for Signs of Neglect

Run the dishwasher, oven and stove. Open the fridge and listen for odd noises. These might sound like nitpicky details, but you don’t want to discover the fridge doesn’t cool or the dryer barely tumbles after move-in day.

Check around appliances for scorch marks, rust or leaks. Worn-out appliances can be costly for a landlord to replace, so they may not volunteer to do so unless you flag the issue before signing.

9. Understand the Security Deposit Rules

A security deposit isn’t just a lump sum — it’s a legal safeguard for both you and the landlord. Ask where it will be held, how and when it’ll be returned, and what deductions are allowed. Most states require landlords to return deposits within a set number of days after you move out (often 30), along with an itemized list of any deductions.

If your lease doesn’t specify those details, request they be added. And before you move in, complete a detailed move-in checklist with photos of every room. This protects you later if you’re blamed for pre-existing damage.

10. Research the Landlord or Property Manager

Even the prettiest apartment can turn sour under a bad landlord. Search online for reviews of the property or management company. Look for patterns — repeated complaints about slow repairs or surprise charges are a bad sign. If possible, talk to current tenants. Ask how responsive management is when something breaks or if they’ve had trouble getting deposits back.

Bonus: Check the Neighborhood at Different Times

Visit the property during the day and at night. A street that seems peaceful at noon might be party central after dark. Listen for traffic, nearby trains or noisy neighbors. This isn’t about nitpicking — it’s about making sure the environment fits your lifestyle. A quiet renter next to a late-night bar might not be a happy match.
