cashing out a lease purchase

[Joe Thomas]

I have a lease-purchase contract with an owner. I found a tenant buyer and sold the property the same way on a lease purchase agreement. The tenant buyer gave me option money and is paying me monthly. I in turn pay the original owner the monthly rent on my agreement. My tenant buyer has been approved to obtain financing to purchase the property. I have an agreement to purchase the property from the original owner for $190k and I sold the property to my tenant buyer for $220. Being that the title as never passed to me, how do i structure the deal to so that get paid the difference in the purchase price on both contracts?
