Hello, We don't currently have a STR, but posting here because many STR use these kinds of devices.   

I would think there would be tons of people who would be looking for passive $ …without shelling out $20K … I know we have a large group of women in CA & several have indicated they want to do wholesaling and flipping and we will be looking for private lenders or silent partners for deals … the FB Group is SoCal women’s real estate investment team

I like egg shell white semi gloss, You can turn off some folks with walls painted many different colors.

I would think a detection device would be easy to fool or disable, and difficult to prove in court.I would focus on inspections and look for the following evidence, then document with pictures, written warnings, demands of cleaning/repairs, and follow-up inspections.

Boom, you are now a real estate investor.Oh and definitely build a corporate web of at least 5 layers of shell companies before you even begin thinking about buying a property.
