The amount you will be approved for will really depend on a number of other variables such as, how much other debt you have, how your income is reported on your tax returns, and a number of other factors. The best thing for you to do is find a reputable lender and sit down with them to go over all of your details. That way, when you begin your home search, you will really know exactly what you can afford and you won't be disappointed or waste your time looking at properties that may actually be out of your financial reach.
