Enter your income, expenses, prospective new home cost, mortgage interest rate and term, and down payment to calculate standard fixed mortgage payment. Construction loan interest is also available to be estimated for new builds and added to your mortgage balance. An adjustment for income and expense inflation is available to help you consider the effect of inflation in the 15 year projection included in the app. There is also a summary of estimated cash required to close your prospective new home. In addition, the app calculates an estimated debt-to-income ratio that bankers analyze, among other factors to determine credit worthiness. The app provides educational insight as to the potential mortgage amount you may be able to afford. The app should not be used for an actual home purchase, since mortgage lender requirements vary significantly from lender to lender. The purpose of the app is to provide a summary view to determine if a prospective home mortgage is within financial capabilities. The final determination should be between you and your lender of choice.
