Vacancy rates will rise quickly.Maybe you could try an Iron A/C cage on the outside and a separate security deposit (maybe around $300 or so) to cover the A/C.The cages are ugly, but in many window A/C communities the residents understand that their neighbors (and their neighbors visitors) may be, shall we say sometimes "theft prone", and the bars can be explained as break in deterrents to keep their belongings safe.They also blend in better in a light color vs. black.If a prospect balks at the $300 and you want them, you could always offer to wrap it into the first 10 month of payments.

(Ironic given the number of security breaches at the IRS, but that's another story.)

Ironically, in line with your interest in Galveston, I am about halfway through constructing a beach home there (Beachside Village), which I plan to use as an STR / vacation rental.

Burn damage in the attic was from a past tenant and their BBQ grease fire, there are also back taxes.
