Is it a normal practice to have a deal set up where you find a new place for the seller to move to?

And all of this happens during the contract period reducing purchasing risk.Great strategy especially when practiced just on the outskirts of a major metro area in a country setting(a weekend getaway property that can be marketed to city folk).  

When I used to have RE Broker in my title ( I still have the license just dont practice) I would get folks pinging me about Vegas about once a quarter or so and I would hand those leads to my Daughter  she made some pretty awesome connections from a few of those folks that bought multi million dollar homes..

If so, can anyone recommend any best practices?

Starting with single-family homes and growing a portfolio one step at a time seems like a practical approach.

They might be fine managing new construction, but I have seem MANY investors almost tank from their fee schedule on managing older homes...i would compare it to almost predatory practice.

Quote from @Hanna Brown: @Jay Hinrichs If the bidder at the auction pays cash for keys to get the homeowner out, does the person redeeming from the owner position (exercising rights of redemption w/in 180 days) have to reimburse them for those costs they paid to get the homeowner out? 

I agree, exercising patience and being a force for positive is the only intelligent self-serving actions I see here. 

A lot of education and a little bit of practice is something that one can accomplish with elbow grease.
