@David Sray I am in MD, so not sure if things are different for you, but you can check with the lawyer doing the closing. Our lawyer handled everything. He requested the copies of leases from the seller, totaled up what the deposits should be with accrued interest (we have to accrue interest and pay that back to the tenants upon move out here in MD), figured up the prorated rent for the month that was due to us, and then he automatically moved the security deposits and rents to us at closing from the sellers statement. It was then our responsibility to put those security deposit funds and rents in the appropriate accounts.
The seller was a little upset, since one of the tenants did not pay yet for the month, but I still got a prorated amount for the month since it was the landlords responsibility to collect that rent before closing.
So for us, it is not something that the seller had a choice in, or he gave us a check personally. Everything was handled by the lawyer. That made it a really easy transaction.
