courthouse investing

[Dustin Gott]

If a bank is owed 200K on a mortgage that goes to the sherriffs sale but the bank only bids 150K and then the homeowners sell the property during the redemption period for 190K does the bank get 150K or the full 190k? Secondly in the above example if i went to the courthouse and bid 151K could I just get the homeowner to sign me over the deed? Would the bank have any say over what happens next?
