Purchasing a Home Under Land Contract

[Joshua Beeler]

I am currently working on a deal that involves a home that is under a land contract. How do I go about buying a home where the land contract has not yet been paid in full. I will be buying the home with a conventional mortgage. Do we involve all three parties in the sale? Would the person on the purchase side of the land contract sell the land contract to us then we in turn buy the home with the conventional mortgage? 

Any insight would be great!
