It doesn't matter how well ventilated your attic is - warm moist air from a bathroom hits cold air in the attic = condensation.

I'm a military dude myself (Air Force) and just started investing back in April.

If you are not going to be adding equity value I believe it is better to brighten it up with paint on walls and floor, use bright lights, and put air fresheners that are ODOR Killer not a scent. 

It has a new furnace and air conditioner, new water heater, new main electrical panel, new carpet and paint, new range, and is brick, so minimal exterior painting will be needed on the eaves when the roof is replaced, about 10 years from now.   

Also remember to protect items in the units such as refrigerators, stoves, and window air conditioning units.

Check out the epa statement on mold....basically that it is "impossible to eliminate all mold and mold spores in the indoor environment"  So isn't it likely that whoever tests for mold is very likely to find something that can then try to sell you additional remediation services on?

There was another AIR BNB thread on here I believe last year sometime and the person finally  got AIR BNB to cave in and make it right.

Can't think of any pro's for YOU, only for your up-until-midnight washer-dryer-heater-air-conditioner-dishwasher-TV-stereo-blasting-abusing tenants!

(you could say it was luck BUT I was new in this area an was only willing invest  in counties/town where the census data was showing a stable population gains, past and future)   Noways I have about  $1000 true cash flow for each, including reserves,  dept service etc.......It is called creating wealth from thin air!

Recently bought a house with a 1978 Jenn-Air electric range.
