Short Sale - Nationwide Credit/Ocwen?

[Chris Karley]

I found a lead off of some mailers that I sent out. Their mortgage was originally held by Ocwen, and is now with Nationwide Credit. I believe Nationwide Credit is a debt collection agency owned by Ocwen. The fact that I was talking to a collection agency and not the bank set off some red flags in my head. 

Anyways, they're offering a payoff of ~22k, but the house is trashed and damaged from some nightmare tenants. To re-evaluate their number they're asking for:

Appraisal Report (at my expense) - I expect this to come in around ~15k and for them to accept around 80% of that number. 

2 months bank statement (seller)

Social Security checks (last 2)

Hardship Letter

Signed Purchase Agreement with Closing Statement 

Is this legit? Has anyone dealt with Nationwide Credit before? Their agents are offshore based out of India and refuse to allow me to talk to the "investor" directly. I'm assuming the "investor" is Ocwen. Should I move forward with this process or run away? Any guidance would be greatly appreciated.
