Seller Financing Interface Online

[C W]

I'm planning to build a website solely designed for the purpose of properties with potential seller financing and am planning to make lease options the primary method.

I want to form an interface for sellers and buyers alike, and especially get the word out to the realtor community in order to get their potential lease option properties/seller financed properties on the site.

This project is in the very preliminary stages and I am still in the process of deciding exactly what it is I'm planning to do.

Any ideas, suggestions, ideas are very welcome.
