Ok, I have a hand full of short sale files on my desk.Clients already agreed a SS is the best solution.

To answer @Shawn Thom 's question, if you Google it you can find the solution for your particular cell phone.

I use Paypal to request funds from tenants that do not already have their own ACH solution; some of them already have a pay-out service via Chase Quickpay, Capital One P2P, or old-school auto-ACH via their bank.For tenants that setup their own ACH through their bank, they pay their normal rent; for those use Paypal for debit/credit card to pay rent, they get a processing fee added to their rent balance.

I always offer other possible solutions and eventually drop into the conversation kind of what "we" do and the reasons people might choose to sell to us.

Have you used any other PPC solutions?

This would be my solution to the 2 unit legality so I can charge my second tenant more rent. 

Trying to fix a problem created by the previous solution where the previous problem was the same as the current and the current solution is the same as the previous right. 

I think the solution is in your original post. 

I also considered that the equitable solution would be to explicitly state in the contract that if Landlord does not deliverpossession, then Tenant is entitled to damages not exceeding the amount of security deposit.

If it is a large apartment complex I would consider a lawyer too, That is if they aren’t reasonable with coming up with a solution.
