The house is in pretty rough shape from driving by (old tar and gravel roof, window ACs, etc) , so even my $150k or so estimate of value is likely a little high, even on the open market, probably more in the $130-135k range. 

Then it pays to have the hardwoods refinished and the windows replaced, stage it and sell it!

I'm looking for recommendations for a window repair company.

Also keep an eye out for evidence of any lease violation.... unauthorized occupants, unauthorized animals, tampered smoke alarms, damages, etc.In addition to checking all of the smoke alarm devices, plumbing fixtures, electrical fixtures, appliances, and operation of doors and windows, ask the tenant if there's anything that's not working or needs attention.

Since we own a bunch of properties, we are able to absorb the expense, but that is a lot of cash flow out the window!
