I'm not sure what leverage you would have outside of taking legal action, these are generally things that should all have been on the closing statment along with deposits etc. 

They batch the deposits together and you have to go deep into the program to determine which tenant made the payment, that was deposited into your account.

Im assuming that is what would catch any errors in owner distributions, deposits, profit/loss? 

It's written into the lease that tenants must deposit their rents into that particular account (either by online bank transfer or by walking in a check/cash); I do not collect rents directly, nor would I if anyone asked.

Actual foreclosure is on the East coast a Sherrifs sale and you can google the state and sherrif sales and the rules will be on the websites.. but its one of two process's either it requires a non refundable deposit if your the successful bidder or you need full cash at the sale.
