A driver of the litigation was this exact point aka "steering."

It would be a residence, and most brokers won’t be able to fund it with a DSCR either due to the litigation issue.

There's an entire semester-long course in law school called Civil Procedure (the absolute worst - *shudders with fright at the memories*) about figuring out the answer to that question based on the facts.

I don't foresee any advantages to litigation in your case unless you can demonstrate the work was done incorrectly which doesn't appear to be the case.

Account Closed would send the actual personal information (privately), I'm sure there are some of us who could locate the sister, or at least her last known location and contact information.Further, if the fact pattern supports it -- after all, the claim is that one sister was attorney-in-fact for the other -- the missing sister may not even be an essential party to the litigation.

The seller has to sign cancellation docs and if they think wholesaler was screwing around with them like many wholesalers do.. they simply wont sign and your money is stuck and you would have to litigate it to get it back unless of course the wholesaler cuts you a check personally but I think before they would do that they simply go find another gator who does not know any better. 

Police deal with criminal matters not civil.
