It does seem like it is such a significant misrepresentation though, I wonder if getting some confirmations in writing helps.

I have heard, but haven't confirmed, that these credits can sell for up to $100k per acre in places like nearby Seattle.

I would reach out to @Dave Foster to confirm.  

He said the house had looked way better before the current contractor started, which was confirmed by neighbors and other people who had seen the house.

I sent an invite to a prospective applicant that qualified and Looked high and low for the invite form with some additional notes to the applicant only to find out that it is not even on the platform at all, anywhere but in an email confirmation I received.

Ask them to confirm the license is still active.

But, for instance, I sent them a notice of rent increase effective February 1 and needed them to confirm that they have accepted the new payment terms through our electronic payment system, and even after repeated notices, they are not responding.

Have you confirmed you can rent the basement.

However, no one at PennyMac was able to provide documentation nor were they able to confirm that our monthly payment would remain the same after transferring to the LLC.  

More often than not they fess up and kind of confirm they don't meet requirements if that is the case.
