Sometimes you can find someone that is willing to sell to you at a discount since they are tired of owning it, and want to use the money to focus on a more passive investment.

Great Thank you Mark for your asnwer, very helpful.I am looking as something a little more " done deal" thank an option to by as from what io understand the seller can still sell to other parties. is there a close that stops that?

The lenders have loan products they want to sell.

It's better to connect and build rapport and let them ask you for deals.Reach out if you have any questions or need help selling a property. 

After selling the house on a lease option, I left some money in the deal (about $15,000).

If pressed in person, I'd be cordial but vague, non-committal and in a hurry, I might imply that I"m considering selling or something completely unrelated to him.

Selling you a product is easy but relating to you based on their personal expierence is not.

Are you essentially acting like a contractor, but just within an airport environment and selling the renovation while your client holds the lease or is there another process I'm missing?

You make money on the purchase not on the sell of the property.   

Are you planning on being an agent and helping other people buy/sell houses?
