Q: My mortgage was fixed for five years and is set to start adjusting in five months. I talked with my mortgage broker and she said that my payment will go up by about 40 percent at that time, which I certainly cannot afford. She ran some comps and told me that I owe $100,000 more on my home than it is currently worth. Her advice was that I should buy another, lower-priced home right now, and then just stop making payments and let the bank foreclose on it. Should I walk away from my home?
