Learn the basics  of real estate and understand the basics of finance before you try seller financed deals........ yes, it takes an effort to learn.

Before getting creative ideas, need to understand the basics and the rules of the road.I'd also say you have two Realtors who must be idiots and see a larger commission check. :)

If you don't know what wholesaling is, here's a link:http://www.biggerpockets.com/renewsblog/2006/11/25/wholesaling-real-estate-basics/

I'd be happy to discuss this with you at any time though.Its basic structure involves 3 partners:1 - Cash = They bring all the cash, have no mgmt or loan responsibility2 - Credit = They qualify for the loan, have no cash in and no mgmt responsibility3 - Management = They manage everything from the start of finding the property, through offers, negotiations, closing, etc...Like I said, the full explanation would take up the entire page.  

Sounds like something basic that would be gone over and hashed out prior to lease signing.
