Paint and carpet with minor rehab.

Nobody wanted it.So we bought it, redid everything from floors to siding, fixtures, master bath, kitchen, paint in and out.

If you don't care how it looks you could put it in conduit and surface mount the conduit and paint it to match the wall color.I would get someone to tackle this immediately and communicate with your tenants so they know you are working on the problem.I would make sure your heat is handled first if this is affected.Then work on any other 240VAC circuits such as dryers, stoves and hot water heaters if applicable.Then get the lights last.I would try and do this without moving tenants out.I just had a 2 story house rewired and it took a week but they worked around the one guy that was living there and he was very understanding of the situation.

Sweat equity on painting, landscaping, general curb appeal What was the outcome?

(paint, flooring, etc.)

One unit is vacant and needs minimal work since the previous owner just put new carpet and paint into it.

They painted the entire interior, re-floored, fixed damage, etc.

Aside from that, he expected the roof to be done this past weekend and then painting the entire house would be done this week.

Should I just always assume I'm going to need new floors throughout, new cabinets, countertops, appliances, most or all of the light fixtures replaced, new paint in and out.

We're currently doing some mild cosmetic renovations like flooring, paint, and code updates in all three units.
