The tenant fails to pay their last month's rent and leaves the place needing new flooring and paint.

And also the contractors - they know what it costs to replace a floor with LVP per sq ft. 

He earned quick money as a wholesaler, and I have a house to keep)Rehab cost: $20k (vinyl floor, interior paint, new dual pane windows, new toilets and bathroom vanities, lights, new landscape, new AC condenser, all done by handyman, spent some extra money for minor plumbing and electric jobs, hydro jet sewer lines, clean up attic (had mice), added some insulationTime spent: 3 weeks (two handymen for the first two weeks, one for the last week)Value after repair: probably around $440kJobs still need to be done later: some dryrots, roof work (it's tile roof, roof doctor quoted me $9k, handyman said probably $5k, home inspector said $15k you can get a new shingle roof.

This helps protect the walls, woodwork, and floor covering while moving things in.

Either negotiate a good price or only pick upgrades that's necessary in the rough phase and do the upgrades with your own subcontractor/vendors after the house closes (kitchen upgrades, appliances, countertop upgrades, flooring upgrades, landscaping upgrades you can get them much cheaper without going through the builder).New construction is a winner if all things are the same. 

We are considering developing it into a multi floor climate controlled self storage facility. 

So, I tried to help the situation by getting a contractor to go replace the floor and remodel the bathroom so that the house is nicer for her.

Personally, the last thing I would want to do is purchase a STR in a community where every neighbor is my competition and floor plans are similar if not the same.

This tenant operates a resale business and is currently renting a single unit on the ground floor.

In these instances, you'd have to check things like flooring, plumbing for leaks, roof for leaks, hot water heater, and heating and air conditioning units.
