@Account Closed yes a lot of this you can do yourself keep in mind the time it takes as well. I am going through what I call "it's just" syndrome on my first property..
as in "it's just outlets" and switches and new electrical in the kitchen, removing a ceiling fan (that wasn't boxed in) to just a light which also was on an always hot circuit ie no switch control.
"it's just cabinets" and then drywall and patching floor tile, adding pex plumbing to get rid of old small copper
"it's just staining a deck" which is uneven and needs boards removed to raise the joists to get them somewhat even.
Youtube is your friend. A detailed shopping list is your friend to avoid multiply trips to the store. Since you're living in the unit time is somewhat on your side.
I'd recommend LVP for flooring.
you'll need a table saw or circular saw for cutting, also a pry bar to pull the joints together. a good box cutter knife as well. tape measure and pencil.
also use pry bar to remove shoe molding at baseboard if there is any. and then a nailer or hammer and pin nails to reattach shoe molding.
Brush and roller for painting.
you'll need a 3 inch good brush for cutting. I use a 7 inch roller for back rolling and then a 9 inch with an extension for painting the walls. you'll need paint liners, a hand held bucket for cutting, tape, drop cloths, spackle and drywall knife or 5 in1 paint tool for filling holes. gorilla platform ladder/station.
Toilet
buckets to drain water that's left in bowl after flushing and shutting off water. new wax ring. new bolts. silicone to seal around the front and sides of the bowl at the floor. rags. channel lock pliers. place for old toilet (trash but make sure you've got room)
Ceiling fan
voltage or electrical tester MUST HAVE to ensure that when you cut the power it's actually off. wire nuts. screw driver. electric pliers to cut and trim wire. proper mounting box. additional romex wiring or attic access in case you need to move to a switched circuit. also a step ladder
Doors.
paint and proper rollers for trim/cabinets. wood shims. level. drill/driver. new trim around door? nailer. door hardware. screw driver.
A GOOD WET/DRY VAC! I have a rigid brand and think it's awesome.
you can do all these things just be aware of the little things behind "it's just a door". ask me how I know.
Home RenoVision on youtube is a great channel.
Good luck. Know when to call for help. Lesson I'm still learning is it all takes more time than you think.
EDIT TO ADD: it feels really good when you accomplish the project though and can tell people you did that. If you're single use that to your advantage :)
