The tools to buy first when you buy a house

Buy the plunger before you need the plunger.

That sounds like a joke until it's 11pm on a Sunday in a house you've owned for nine days, the downstairs toilet is filling instead of draining, and the nearest open store is twenty minutes each way. Get a flange plunger, not the flat red cup one. Set aside about $20. Put it behind the toilet it's most likely to be needed for, not in the garage.

That's the whole logic of a first tool kit. You're not building a workshop. You're buying the ability to handle small problems at the hour they happen, and to stop bigger ones from getting worse until somebody qualified arrives.

Under $150: the first weekend

This tier isn't about projects. It's about not being helpless.

• Flange plunger and a cheap plastic bucket. The bucket goes under the leak.
• A good headlamp, not a phone flashlight. Water shutoffs live in crawlspaces and the back of cabinets, and you need both hands.
• Channel-lock style tongue-and-groove pliers, 10-inch. Channellock's own are the reference, and they're cheap enough that there's no reason to go off-brand. These loosen supply lines, P-traps and hose bibs.
• A 16oz claw hammer. Estwing's one-piece steel is fine forever. Skip fiberglass with a loose head.
• Ratcheting screwdriver with a bit set. Get one that takes standard 1-inch bits so you can replace them.
• 25-foot tape measure. Stanley PowerLock is the default for a reason.
• Adjustable wrench, 8-inch.
• Utility knife with a stock of blades. Change the blade far sooner than you think you need to.
• A level, 24-inch. Torpedo levels are for plumbers. You want the one that tells you whether the shelf is straight.
• Stud finder. The $25 electronic ones are adequate. Verify with a thin finishing nail before you commit to a lag bolt.

Two more things that aren't tools. Find your main water shutoff and your electrical panel on day one, label the panel properly in pen, and keep a quarter-turn water key if your shutoff is at the street. Knowing where the valve is beats every tool on this list.

What to skip, permanently

The 200-piece homeowner kit in a blow-molded plastic case. You know the one. It looks like tremendous value and about forty of those pieces are metric sockets you'll never use, a hacksaw that bends, and pliers that chew up the first nut they touch. The case cracks within two years and nothing sits back in the right slot anyway.

The other thing to skip is the very cheap cordless drill sold as a standalone with two nickel-cadmium batteries. Batteries are the expensive part of a cordless tool, and those ones die on the shelf.

$400: the kit that covers most Saturdays

Add to the above, in this order.

A cordless drill/driver kit, 18V or 20V, with two lithium batteries and a charger. This is the single biggest jump in capability you'll make. Ryobi's One+ line is the value pick, partly because the battery platform stretches across an absurd number of tools including a leaf blower and an inflator. DeWalt's 20V Max and Milwaukee's M18 cost more per tool and are what most trades carry. Makita and Bosch are both excellent and slightly less common in U.S. big-box stores.

The real decision isn't the drill. It's the battery system, because you're choosing the family of tools you'll buy for the next decade. Pick one and stay there. Mixed platforms means four chargers and never having a charged pack in the one you want.

Klein or Wera screwdrivers, four of them: #1 and #2 Phillips, a 1/4-inch flat, and a small precision set for appliance panels and eyeglass hinges. Bit drivers slip in old, painted-over screws. A proper fixed-blade driver doesn't.

Needle-nose pliers, lineman's pliers, and a wire stripper. Even if you never touch a circuit, you'll be replacing a lamp cord or a thermostat sooner than you expect.

A 6-foot fiberglass step ladder. Fiberglass rather than aluminum, because the day you're near anything electrical you'll be glad. This is the item people delay the longest and regret most, usually from the top of a kitchen chair.

Caulk gun and a case of caulk. Dripless, with a rod release you can work one-handed. The $4 gun makes a mess of every bead.

A hand saw or a compact circular saw, depending on whether you want to cut plywood or just trim a stuck door.

Safety glasses and a box of nitrile gloves, plus hearing protection if you bought the saw.

$1,000: the point where projects get easy

Now you're buying speed and finish quality rather than capability.

An impact driver on the same battery platform. Different tool from a drill, and once you've driven thirty deck screws with one you won't go back. Most brands sell a drill-and-impact combo kit that costs barely more than the drill alone. Buy the combo at the start if your budget allows.

An oscillating multi-tool. It's the ugly-duckling tool that cuts a door jamb for flooring, trims a stuck baseboard, and removes old grout. Blades are consumable and the cheap off-brand blade packs are genuinely fine.

A random orbit sander and a shop vacuum. Buy the vac with a HEPA filter and a hose that fits your sander's dust port. Sanding without dust collection is the difference between a two-hour job and a two-day cleanup.

A socket set, 3/8-inch drive, metric and SAE. Assembling furniture, lawn equipment, car maintenance.

A digital multimeter and a non-contact voltage tester. The tester costs about as much as a pizza and tells you whether a wire is live before you touch it. Both of these earn their space.

A miter saw if you're planning trim work. Skip it if you're not. A 10-inch single-bevel handles baseboard and casing in a normal house.

Rent instead

Tile saw. Concrete mixer. Floor sander. Jackhammer. Auger. Pressure washer, unless you'll use it more than twice a year. A carpet stretcher, which most people have never held and will hold exactly once. Home centers rent all of these by the four-hour block, and the rental fee for a whole weekend is usually less than a tenth of the purchase price.

Rent the big one-off item and spend the saved money on better hand tools you'll touch every month. That's the trade most new homeowners get backwards.

Where cheap is fine

Harbor Freight's house brands have gotten good, and for anything you'll use three times a year, they're the sensible call. Clamps, pry bars, sawhorses, a drop cloth, a wheelbarrow. Buy cheap and don't feel bad about it.

Where cheap costs you: anything with a blade, anything with a battery, anything holding your weight, anything that measures. A bad tape measure is worse than no tape measure because you'll trust it.

The limit, and know where it's

Gas lines. Anything inside your electrical panel. Structural walls. Roof work above one story. Sewer laterals. Get a licensed plumber or electrician, and check whether your city requires a permit before, not after. A permit costs money once. Unpermitted work costs money at closing, in front of a buyer's inspector, with your leverage gone.

Start a running note on your phone the week you move in. Every time you reach for a tool you don't own, write it down. By month six that list is a better shopping guide than anything anyone else can give you, because it's about your house.
