They'll have similar or if lucky exact door matches.

Since I got his deposit at close (she didn't send to him), it was my responsibility to send to him.I sent 100% of it back.

What are your opinions about returning the full security deposit as versus retaining the last months rent out of it?  

If a tenant does not have a Landlord reference for the past six months or more, I require a double deposit and good/excellent credit.

All it takes is one major issue, such as the insurance deductible for a storm damage claim, a tenant to do damage above and beyond the security deposit - never mind the loss of income while it's being repaired, or evicting a tenant who hasn't paid, etc. ... to turn break-even into a loss.

If this scares you then you can always include a contingency clause with respect to that deposit, BUT you should always be wholesaling a property that you do in intend to purchase just in case you can't find a cash buyer. 

Also, you could get part of the assignment fee as a non-refundable deposit.  

As long as you're charging a big security deposit they'll take care of it.The septic tanks are configured where each home has a 1000 gal septic has ( 2, 500 gal tanks) and each tank runs to a field where the water drains into.

I've been burned too many times matching the online bid, only to have the seller up their bid to an idiot amount.  

Promise them all the deposits in return for doing the deal.
