However, my current business doesn't pour off enough capital to really be able to get a start there, and I'm getting burned out on it after 11 years. 

You need to make sure you offer with a good amount of lease option money to the seller and be fair with your expectations or the minute they run a ridiculous scenario/ offer by their attorney or realtor, you're out like the fat kid in 5th grade dodge ball! 

No wonder the USA is fat and sick.

So I can pay cash for the next deal and get out from under interest payments, or do I keep them as a slow burn, unfortunately I'm kind of tapped out while I have these two places, and any other house purchasing would have to come from the profits off these places.

not sure what he heart burn is here.. if buyer and seller agree to cancel EM should be returned within a day or two.. if lawyers are messing it up.. that is a huge problem.. and again name brand title and escrow companies simply would not work this way..

I don't want to burn any bridges or just blow anyone off.

I guaranty if you were to battle anther realtor with a borrower/ buyer who was to do as I described above, 7 out of 10 times you would lose down here in FL  with that outdated strategy of "Poor Mouthing the Offer" with ridiculous Good Faith Deposit amount in escrow.If I were selling a 500k home, and an a buyer hit me with a 5k deposit, their offer would be out like the fat kid in 5th grade dodge ball!

This is the first year I am managing it myself having burned through 3 property managers in about as many years - costing me more $$ than it was worth. 

What is someone burns it down?

What would you do if you were to explore this option and how would you prevent yourself from being burned?
