Reddit mentions of DEWALT (DWMT73804) Socket Set, 3/8-Inch Drive, SAE/Metric, 34-Piece

Start with a basic tool kit: screwdriver set, hex wrenches, pliers, box cutter, level, hammer, ect.

Something like this.

Then i definitely recommend socket wrenches.

Next I'd recommend an impact driver. There are going to be times where your drill won't cut it.

I purchased a circular saw recently and have gotten a good amount of use out of it. If you don't plan on doing any woodwork then pass on this.

Probably outside of your price range if you're sticking to $300 but a pressure washer is amazing. I use mine all the time.

Another extra item would be an air compressor. You can use it for tons of stuff such as nail guns.

And then also you'll need all your yard work tools. Loppers, shovels, rakes, trimmers, ect.

Oh man.... All the stuff to maintain your home is so expensive. But I'd start here.

This one is pretty nice, plus it has metric in case you need it. But you’d have to get a separate deep-well kit like this one .
