This mortgage refinance calculator will help you navigate the mortgage refinance propaganda by discovering if a mortgage refinance will help or hurt you. My model is, "homes are for living, not for loaning". The reason, many people who take mortgage refinance loans against their homes later loose them. This is due to the complexities of second mortgages, and in some cases, tricks mortgage companies pull with second mortgages. There are rare cases a second mortgage is a good idea, such as the new federal government program for homes "under water" so to speak, from the bad home loans of the past decade, designed to save your home. Your interest rate and payment will be stabilized in the new programs. There are also rare cases of people with high income, high equity, and no money in the bank for a severe medical emergency, who may consider a mortgage refinance loan. ~Lois
