This mortgage qualification calculator, also known as a mortgage calculator, will give you information most mortgages companies don't want you to have. The answer to the question, What is my real mortgage qualification? Most mortgage companies over estimate your "real" affordability so they can sell you the most expensive home possible, and therefore they will get the highest commissions. When most folks decide to buy a home, they call up "any mortgage company" and say, "I need to get qualified for a mortgage, I am buying a home". That's not the first thing to do. But, that is why a lot of unsuspecting home buyers of the past decade were given the bad "interest only" loans, that put them in foreclosure. Many had good credit, good down payments and a great ability to pay a quality home loan. The problem was they did not do their research before they started. First start with researching types of mortgages, what is wrong with some types of mortgages, then research mortgage companies. Then, call honest and qualified mortgage specialists.
