Also find out if they are licensed and talk to that board.The fact that you haven't been paid the rent and they aren't answering their phone is not a good sign.It shouldn't take a long time, but it may cost you to break the contract. 

@Steve CastagnettaBe honest have not really found a very good one - and I always question data - why?

In Tampa area I am well connected as a PM and broker and have a lot of off market in addition to MLS. 

There are many hard money lenders who do DSCR with less ins and outs and less rules.

Only challenge (as you and others have touched on) is scalability.

It's been a while, but I had a few guests contest charges and I won every time.

Who is your favorite DM list provider and why? 

There is a reason we lenders require "skin in the game" and experience.

Austin and it’s surrounding is on the top three list for highest decline and short term rental revenue.

Sounds like you are on the right track and at the right place here.
