Everyone here will try and sell you something based on what you're describing.

I never plan to sell other than as a 1031, if that. 

My realtor (and friend) owns a number of properties and recently offered to sell one to me through a lease purchase agreement.

Or, if that doesn't happen, the first one of you to sell a house will have the proceeds of that sale yanked from you by the court before you even touch them, even if it's ten years later. 

You are offering less than market value and then selling that contract at a higher value.

You can get higher but the rates will be higher as well and it will be a lender that doesn't sell the loan to Fannie. 

FYI: If I keep I will be sidelined for 8-12 months until I can buy another deal.What you guys think Keep a fully renovate home for 66k in a C+/B- area or sell for 107k for the next deal?

I've had clients pick up a half dozen homes without ever putting more than 5% or 10% down or selling any of them.

My personal opinion is that unless there is no other way to sell the house, subject to should only be used when BOTH parties are sophisticated investors.  

Or should I sell and jump start my real estate acquisitions?
