I don't really want to invest in a D-class area.Tangentially, what are some of your "it's time to sell this property" red lines when it comes to the changing economic conditions of an area? 

On the other hand if they are a sponsor that is experienced in stopping a skin in the game, that's a huge red flag for me.c) how open to scrutiny are they?

FD came and red tagged the outlet.

Ready for some nerdery? 
I believe that the Federal Reserve is going to cut rates by 25-50 bps at it's September meeting (no emergency cut), but that 30-year fixed rate mortgage rates will rise to upper 6s low 7s aro...

Knowingly buying into the red just because of financing terms is a very unhealthy way to invest.

The fact that their documentation is not clear and they are in a hurry to move is a big red flag.

We've only had one resident fail to pay rent, and it was someone who had all the usual red flags, but she also had a sick kid. 

The only slight red flag was that they only accepted payment via Venmo or wire transfer, but that's how I accepted payment when I was selling lead bundles, so I still thought it was worth a shot.

These are business purpose loans so there isn't any sort of red tape when purchasing multiple properties at once or one after another.

(and be able to buy themselves a new Porsche with the proceeds)Just more Red Tape!
