I bet there were some takeaways looking back. 

Check out passive pockets and see what reviews are there.

Behind referral on on-line sources like Next door, Google review, FB marketplace, etc.  

I recommend you speak with a lender about reviewing whether you could qualify for a loan prior to making an offer, as I've seen these kinds of things blow up.

Speaking of DSCR in particular, 80% will likely be your best bet versus 85%.

You shouldn’t have to go to a second platform to verify a booking.I’m happy to jump on a call to review your current occupancy compared to the market, as well as “the anatomy of a statement.”

Thinking you can identify scammers by speaking to them or reading reviews is naïve.

There were only three reviews about them on Yelp and they were negative as well.

The property was worth around $60M but they were doing a capital call to pay down the loan balance but that still had them at negative cash flow and no exit as they could not refinance and the originally equity was basically gone (or would be gone by the time they sold the property).So anyone considering a capital all, either review the numbers or engage someone and pay them to review it for you, just as if you were going to have someone review the initial deal.

Hence if the lease clearly has terms against this and section 8 is supporting the rent, that is your best bet to ensure the tenant complies with the lease.
