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.

@Heather Plude is in fact a salesperson for the hi tech air that she gave she such glowing reviews of.  

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!
