this is the most transparent scammer outthere, i am actually very worried about OP if they can't detect this easily, he is selling mortgage, oil, insulin and tax services in one hospital out of ohio somewhere...come on...

There is a new smoke detection unit that has been appearing on my facebook feed which also does noise detection and is being marketed towards STRs.

The key though is to make sure you have a good team on the ground and you are also aware of the risks in the marketplace you will enter along with investing from out of state.

When you build business credit with business credit cards, most service providers I've found in Bigger Pockets market Place are interest free for the 1st year or so. 

If it is in bad bad bad condition and you are not a contractor I would probably sell it.A few months ago I sold a home and after about three months they gave it back to me and then I put it on facebook marketplace and sold it again.

FB marketplace 

Not sure if the answer isa) nothing I can do about it, b) put a wireless water meter to help detect leaks on it (how does this work for a rental where the internet is theirs?)

Gmail , Zillow , fb marketplace, Chime and a whole lot more even after having proof they are robbing people under false pretense are CONTINUED to advertise, rob and all on their platform.

I use these:LEPOWER LED Security Lights Motion Sensor Light Outdoor, 38W 4200LM Light, 5500K, IP65 Waterproof, 3 Head Detected Flood for Garage, Yard, Porch (White) - Amazon.comWhen flipping out of state I go Simpli Safe.When it comes to local flips I have a home security contracting company that has their own alarm system and app that I really like so I use them but they are local to Cleveland. 

Try putting your ad on other sites like Facebook Marketplace and Craigslist too.
