I cannot give you an intelligent answer to the question without knowing his entire financial situation and future plans. I will say this much though....big businesses, including banks have no problem renegotiating deals, getting bailed out, restructering debts, walking away from deals, etc. when it makes business sense to do so. Heck, a lot of these mortgage companies feel there is no need to pay their appraisers in a timely manner or, if the appraiser did not play ball, pay them at all. It is only private individuals that are supposed to have some sort of moral obligation to not to walk away from or renegotiate deals and just continue paying no matter how stupid of a business decision that may be. Seeing how the mortgage banks in large part created the real estate bubble through their fraud, use of bogus appraisal, their proliferation of unsound credit standards and lack of underwriting, he should not feel bad about hanging the loss on the loss on the mortgage bank if that is the sensible thing to do business wise. Mortgage lending is a business, and defaults are just part of the business. People should treat banks and mortgage companies exactly as they would treat us, no better and no worse.
