The first thing that I did was security. 2x4 braces on the back and basement doors, security cameras that have a blinking light so people can see them, fix the fence to temporarily be without a gate, secured air conditioner, secured garage door, curtains on windows etc.

I renovated the empty unit at closing helping increase income immediately and the exterior is about 60% done now, just need to do the curb appeal aspects and re-foam the roof. 2/4 air conditioners replaced.

I'd like to add that as you rehab and replace items on the maintenance list to research durable materials to build and upgrade with and supplies to help make your place last longer like cabinet conditioner and tile sealer, deck/patio refinish etc; also pay the extra dollar for quality.

Your duplex in El Paso needs a new Air Conditioner ($3500) and your house in Dupont needs a new roof ($8000).

I ended up providing these tenants with a new mini-split air conditioner and new patio door.

They put a window unit air conditioner in there so that was clever.

Another electric heat option - an heat pump stye air conditioner  with a heating mode.

He chewed the plug off a wall air conditioner (why it didn't electrocute him I'll never know)3.

But what I found out after having it survived is the land stops about 3 feet from the side of it so the driveway and the air conditioner are not even on my property most of the septic are not on it either.

Humidity can also cause it, if they didnt use the air conditioner trying to save cost.Wet mopping can also cause it.
