First apartment, first set of keys, and suddenly you notice everything. The bathroom mirror looks bare. A door squeaks every time you open it. The phone charger keeps falling out of the outlet by the bed. Whoever lived here before left a row of nail holes over the couch.
None of that has to wait for maintenance, and none of it has to put your deposit at risk. Everything below goes on without power tools, comes off or blends in, and asks very little of you. Start with whatever bugs you most.
Wood-Grain Peel-and-Stick Border Tape

That big frameless builder-grade mirror can look like a custom piece in an afternoon. This removable, waterproof PVC tape has a wood-grain finish. Run it around the mirror’s edges and you have a frame, no drilling and no new mirror needed. It also works as trim on kitchen and bathroom tile.
One buyer whose bathroom mirror would have been expensive to replace tried this instead and loves it. Her tip is to go slowly and smooth it down as you go to avoid bubbles. She says it looks and even feels like real wood grain. Two sizes.
Best for: A big visual change you can peel off at move-out.
Erase-A-Hole Wall Repair Stick

Hung the gallery wall a little too eagerly? This quick-dry filler goes from the tube straight into nail and screw holes in drywall, wood or plaster. There’s no putty knife, no sanding and no trip to the hardware store, and you can paint over it once it’s dry.
One buyer used it to cover staple and nail holes before moving out. She rubbed it in with a circular motion, pressed it into smaller holes with a finger, and wiped the excess off with a damp rag a few minutes later. She said the room looked transformed even before touching up the paint. It comes as a single or a two-pack.
WD-40 Precision Pen

It’s the WD-40 you already know, shaped like a marker. The fine pen tip puts lubricant exactly on a squeaky hinge or sticky lock without overspray on the walls or floor, which matters when the walls aren’t yours. It also helps prevent rust.
It comes as a three-pack. One longtime WD-40 fan keeps a pen in the glove box, one in the kitchen junk drawer and one in the toolbox.
Self-Adhesive Caulk Tape

Yellowed, cracking caulk around the tub or toilet is one of those things you stop seeing until a guest arrives. This peel-and-stick strip goes over it about as easily as a Command strip, with no caulk gun and no drying time to plan around. It works around tubs, toilets and kitchen counters.
A buyer who used it around his toilet base said it went on easily, hid the discoloration and looks much better. It comes in two sizes, in white or clear.
Good to know: Clean and dry the area well before applying so it sticks properly.
XFasten Transparent Weather Sealing Tape

Drafty windows are the classic rental complaint, and the window AC unit you installed yourself probably isn’t perfectly sealed either. This clear tape covers those gaps around windows and doors, so the air you’re paying to cool or heat stays inside.
One buyer had regular tape fail around the plastic panel of a portable AC. This tape sealed it and dropped the room temperature by five degrees. Because it’s transparent, it barely shows. XFasten is a small business. Three sizes.
Snug Plug Outlet Inserts

A loose outlet that keeps dropping your charger? No need to call an electrician. These small inserts fit between the plug and the outlet so the plug stays put, and a set covers several problem outlets.
One buyer had loose outlets both at home and at work and said they solved the problem quickly. She can finally keep a phone charger plugged in in her den. Snug Plugs is a small home-improvement business.
HOTO Home Tool Kit

Then there’s flat-pack furniture, curtain rods and the odd wobbly cabinet handle. For all of that you need a real kit, and this one looks good enough to leave on a shelf. The slim case holds a claw hammer, a multi-bit screwdriver with bits, a tape measure, needle-nose pliers and an adjustable wrench.
One buyer called it the only home tool kit they’d found that isn’t an eyesore, and said the tools are solid quality. Another bought it as a car kit and was pleased with how slim and well organized the case is.
Best for: A housewarming gift, for someone else or for yourself.
One last habit before you start: photograph every room on move-in day, then again after each fix. If your landlord ever asks, you’ll have proof the place looks better than when you arrived.
