General home ownership post:
A bit of background I have flipped 5 houses (doing most of the most), and I own 2 rentals. To my current house I have completely remodeled my kitchen (pictures elsewhere in the thread), have completely gutted my master bathroom/closet (not pictured), redid everything but the tub in another full bathroom. I dont do structural work, large electrical jobs, carpet, large drywall jobs, window replacement, garage door replacement, or large roofing projects (just redid our shed roof last month). I can tell you before I do pretty much any job I watch multiple youtube videos. While my degree is in Mechanical engineering I can tell you right now rocket scientists dont built houses and being able to work on your house is mostly just about your free time and your natural inclination . Chances are you can figure out most things that need to be worked on in your house. That said the question is always going to be the cost effectiveness to hirer someone else and if you trust yourself not to burndown/flood your house.
If you are new to doing household work a couple of things I highly recommend- you are going to end up spending $500 dollars building a general care kit by its worth it.
Roybi has an AMAZING lineup of items. For just general household work that you dont plan on being a professional with I recommend roybi just because of their "massive tool" lineup and good price range.
You will want a drill (and probably an impact driver though not required).
A circular saw (maybe not required)
battery powered tire pressure pump with readout
2 sets of decent bits make sure some have torque (T) bits. Also make sure these are the long bits. The little half inch short ones you are goign to lose very quickly.
A decent set of drill bits (preferably the ones that also fit the impact driver)
A couple of types of flashlights to include magnetic/headlamps/handheld
2 levels (6 inch and 2 foot)
a set of screw drivers
a nice ratchet/socket set (preferably 1 that has both 1/4 inch and 3/8)
a nice hammer
a large set (50) of self drilling drywall anchors (for the love of god and all that is holy do not use the ribbed ones that come with the thing you are buying)
a speed square (Rafter square)
a carpenter square
both metric and standard wrenches, plus a couple of adjustable wrenches (make sure one goes up to 1 inch)
both metric and standard set of allen wrenches
a couple of plyers, to include at least once needle nose
3 tape measures (one that lives in the kitchen or other common area, one that lives where the tools are kept, and one that lives in the tool bucket).
1 pound box of 1 -1/2 inch drywall screws
1 pound box 2 inch all purpose screws
a pair of good wire strippers
wire nuts
voltage detector pen
2 box knives (With easily replaceable blades) -one will live in the bucket and one will get lost
at least 2 pencils - one will live in the bucket
a 5 gallon bucket that has a tool bib. the purpose of the bucket is for ease of movement and reduces the need to go up and down your stairs 18 god damn times because you keep forgetting shit.
A REALLY NICE SET OF GLOVES YOU FIND COMFORTABLE and SAFETY GLASSES (fuck maybe 2 sets of both)
Thats a good general purpose starter kit.
