How much do I pay them per deal and how can I trust they're running the comps accurately?

@Ewan Tong, you can bring in a buyer's agent if you pay their commission.

Do we pay cash for 4 cheap turn keys out of state?

Of course you could look at lease rates on Loopnet and Commercial Search, but I like the low tech approach of going to an area and walking into a business of a similar property and just asking them to be kind enough and help you with some market research and tell you how much they pay in rent.

Are all tenants paying? 

All he wants is enough to pay off the mortgage and for the buyer to cover closing costs.  

I gave option to pay last month rent in 2 payments 10/1/16 and 11/1/16.

The lease payments are paying on the mortgage, the sellers have their money to pay the $10k plus $10k to go RVing.I could get that deal done in no time.  

I'm working on a deal analysis for an REO property & was wondering the odds of the bank paying for closing costs, assuming they accept the offer?

Question, do i buy one and put most of my money as downpayment to quickly pay it off and move on to the next?
