What is the best way to buy a house from foreclosure by a lot?

"The purchase of foreclosure (foreclosure not) at home" and "buy a house in a short sale" sound similar but are two different things. I recommend you learn a little about each process before making a move. None of them means you will have a property by paying the remaining balance on the mortgage.  

Properties in foreclosure,

Or both at the short sale will still be listed based on the comparison in that specific neighborhood, regardless of the balance of the mortgage.

Consider this

Buying a home to pay the remaining balance on the existing mortgage is totally different ball game. To do this, you assume the seller's existing loan with the permission of the current lender. You may have to pay a fee to the lender to assume the current loan. Most lenders generally do not favor them.
