context absolutely matters. if you want a handyman to come over and install a few cabinets, you can probably take on his risk. if you have someone install a roof, you're crazy to take that liability on yourself. you want to use your insurance as a last resort in every scenario, so having the person doing the work covering their own liability is really important. for small stuff when you're new you can skirt around this to create margins a bit, but as you get bigger you want to go more legit and worry more about reducing potential downsides. 

I've done some research and tried to put together some categories but would really appreciate a sanity check.Basic Paint & Carpet - $10/sqftRepainting walls and ceilings.Replacing old or worn-out carpeting.Minor patching or repair work where necessary.Simple Cosmetic - $15/sqftNew paint throughout.Replacing outdated light fixtures.New hardware on cabinets.Possibly updating some appliances or fixtures to more modern ones, but without extensive remodeling.Interior Rehab - $25/sqftPossibly replacing flooring throughout (not just carpet).Full kitchen and bathroom remodels with new cabinets, countertops, fixtures, etc.New lighting fixtures throughout.Possibly updating or adding electrical outlets, switches, etc.Full Rehab - $40/sqftAll the upgrades mentioned in the Interior Remodel.Exterior upgrades such as new siding or paint, landscaping, updating or adding decks or patios, replacing windows or doors, etc.Thanks all!

This causes moisture in walls, even cabinets feel moist (cabinets have warped). 

I will have to get professional quote on it, but the property does look okay from the pics(excuse my mindless assumption), not a single hole on drywall, ceilings look firm and even, floors pretty clean, no visible damage, just in need of some paint work but I did not like the kitchen cabinet)

@Robert Niosi  two things one foundation and two the house was just built out of plumb to begin with.One of the builders here in Oregon was in a subdivision I was building in and they built a home that was 3 inchs off of plumb if you dropped a ball at one end it would roll out the front door... cabinets and doors all looked funky
