While property managers would tend to only look for paint overspray and curb appeal.

With the newly passed lead laws, the state seems to be getting much more strict about demanding landlords have a Certificate of Conformance for lead based paint issues on both the inside and outside of the house.

(New cabinets, new appliances, redesigned kitchen layout, refinished hardwood floors, some drywall replacement, all new paint, etc.)

You also still have turnover costs in multi-family, those units don't paint themselves!

A coat of paint on the walls and cabinets goes a long way.If you are renting out rooms, is there another bathroom?

The work took one week to paint the whole interior except living room and hall way, fix some concrete on the porch, landscape, and a ton of miscellaneous items inside the house.

I bought most of mine from Facebook Marketplace and a local shop that both refinish mid-century furniture with chalk paint. 

List of things to fix:Clean house, Carpet replacement, Floor patch up, Interior Painting, Bathtub recaulk, water heater replacement, leak check, small dry wall cut and restore, Roof fascia repairThank you.
