I hear a lot about standard personal loans, mortgages, etc - but do banks or smaller players consider situations like the above?

Are there any immediate red flags that you avoid?

Are there any emerging opportunities or red flags?

I used Zillow to list my rental and accepted someone's application however after my few interactions with them on the phone some major red flags have come up and I wanted to know am I under any legal obligation to rent my property to this person. 

I can at minimum, provide insight into certain markets/ball players to connect with based on your strategy. 

I’ve noticed a few areas of concern (or red flags) during my research that I’d like to verify after digging through forums.

If he can't provide a track record dating back several years, that could be a red flag. 

Blue, Green, Yellow, Orange, and Red are A, B, C, D, and F, respectively. 

Vacasa and Evolve are two of the major players that could have an opportunity in that area for you to be boots on the ground.

I would suggest to speak with a broker or someone familiar with the process and have them review a full package and try to look for any possible red flags in advance.
