Hello, yes it's actually common for people to give up their home to avoid further payment only if their lender agrees and allows that to happen. But of course, the remaining balance (the difference of the house value and what's left of the mortgage) must be paid. Walking away from an underwater mortgage can seriously affect that person's financial future and by extent his/her relationship with the community. His/Her credit score will go down with this, it may be difficult for him/her to qualify for another mortgage in the future. Another reason is that - in most states, it is completely legal for lenders to go after the difference (deficiency) because technically they own that and have rights to it.
