Start by visiting with any qualified loan officer(s), he/she can best advise based on your total financial picture--Lenders have their income v. debt criteria for qualifying for the amount of a mortgageâ€”oftentimes requiring that housing costs are not in excess of one-third of gross income in addition to a stipulated income v. overall debt-ratio. What lenders donâ€™t know are borrowersâ€™ non-debt spending habits, present and anticipated. You, the borrower, need to consider the economic factors of your lifestyle that would impact on your individual comfort level of affordability. A mortgage outside your budgetary constraints can dramatically alter your overall living conditions. So, be sure to factor micro and macro economic concerns into your mortgage amount deliberations.
