Double closing with a balance left on the home?

[Michael V.]

HI BP,

I am looking forward to my first wholesale deal soon. My distressed seller wants to get rid of his home but has a hefty balance left on it. Of course i want to make sure i get a good portion from this deal but it seems the only way to do this is to offer the seller less than what he owes on his mortgage. Is it possible to double close on this home at a lower price than what my seller owes as long as the seller is willing to pay the outstanding balance and does that mean the home will be a short sale if he tries to get this approved by the bank? Please clear this confusion BP 

Thank you

Michael P.
