Installed new flooring and painted the entire house.

We stand to make a gain of $80k or more on her home if we sell it now (after purchasing it she knocked out a wall, got all new flooring, new paint, updated kitchen and bathrooms, etc.)

Some of the larger expenses-Interior/Exterior Paint, Storm shutters for a few of the front large windows, added additional cabinets to one unit, New refrigerator from Dent/Scratch store after old one died, Laundry units that tenant pays +$50/mo for etc.

We upgraded the bathroom, kitchen, put down beautiful new wood floors, replaced the entryway door and painted. 

Remodeled the entire property: new kitchens, bathrooms, flooring, painting interior and exterior, landscaping, new roof on back unit, opened up kitchen to living room in front unit.

We've done flooring, paint, bathroom and kitchen updates to both the main house and rental.

I've had a maintenance person that will usually get in and clean, repair, paint, and do everything needed to flip an empty apartment into one that is rentable when a tenant vacates the property.

FHA, VA, and Conventional mortgages each come with their own set of rules and requirements or the condition of items such as the roof, plumbing, appliances, peeling paint, floor coverings, etc.

Changed out the siding and new paint. 

There are some skills that I suggest every homeowner learns in order to avoid high repair bills (in order I usually do them):-Fix minor roof leaks & repair siding/exterior-Fix water supply leaks with compression fittings or hose clamps if needed-Install lights, replace bad receptacles, switches, or breakers-Install electric water heater if needed-Fix subfloor & sturdy up framing if needed-Fix/replace windows/doors/glass and install locks-Drywall/mud, brush&roll paint-Install floor (floating/tile) and cut/install trim-Install toilets/sinks/cabinets/faucets-install mini split units if no functioning ductwork
