How to quickly find your ideal mortgage payment

When shopping for a new home (and a new mortgage), it's best to work backwards-figure out how much you can afford to spend on your monthly mortgage payment and use that number to determine your ideal housing price point. How do you come up with that monthly number? Well, one way is to go through your last three months' worth of bank statements, figure out what your spending habits are decide how much you could comfortably spend on housing. The other (quicker) option? Try the 40X rule . The 40X rule is simple-and a calculation that's been used by New York City landlords for quite some time. Divide your annual salary by 40, and you'll end up with the approximate monthly payment you should be spending on your mortgage. Fiddling around with a mortgage calculator will help you translate that monthly number into a total mortgage amount-and, combined with your down payment, your housing price point. While this isn't a foolproof method, it will give you a starting point to look for houses in your price range (and avoid disappointment when you find out that the multi-million dollar mansion you had your eye on is actually not in your budget).
