Purely anecdotal, but we are purchasing a home from family with seller financing.

What do you mean by "seller assisting with closing"?  

Can anyone give information on finding out how to find these motivated sellers or where to obtain list of absentee owners or pre foreclosure.

Kind of the ideal motivated seller that I've been in search of. 

. $1.8Mil AV FMV Purchase for $650K and Seller willing to work with us.Clearly, the property value shows a deal, however, If not for the high income generation per unit, Our Model yields We doubt that buyers are lining up.

My 2 cents you setting yourself up for failure and screwing the seller because you have no intentions on closing the deal or know anyone who is going to.

Have you ever hired a lawyer to help structure complex transactions or seller financing (e.g., rent to own)?

@Jacob AbuataYou could also try marketing to apartment owners that could be motivated to sell (i.e. people that have owned the property for 30+ years, owners who have inherited the property, etc).

Also, what position is the seller in as far as need/want to sell? 

In instances of purchase of property, lease is executed subsequent to buyer entering into a rental lease agreement with inherited tenants.This agreement is preceded by review of due diligence documents provided by seller to buyer.Tenants acknowledges that Agent is entering into this Lease in reliance on the information contained in Tenant’s rental application and or all other information provided to Agent by Tenants or Tenant’s current landlord/property management team in the event of a property sale, all prior to this lease agreement.
