The purpose of this mortgage calculator is to provide a rudimentary analytical tool for prospective home buyers to use in order to conduct a partial analysis of the financial burden that is associated with owning a home. This mortgage calculator takes into account the cost of debt for a mortgage loan, as well as the costs for property taxes, homeowner’s insurance, and private mortgage insurance. With this in mind, prospective home buyers will need to subscribe to use the Adkins Residential Home Valuation Analyzer in order to conduct a comprehensive residential real estate analysis. Prospective home buyers should remember that the mortgage loan interest rate for a 30-year fully-amortized fixed-rate mortgage loan reached an all-time high of 18.63% in 1981 and it reached an all-time low of 3.31% in 2012. Prospective home buyers should also keep in mind that a 30-year fully-amortized fixed-rate mortgage loan of 5.3040399%, 9.3967767%, 13.06281084%, or 16.54621953%, would require prospective home buyers to repay two- three- four- or five-times the amount of the home mortgage loan. Prospective home buyers can use this mortgage calculator in order to evaluate the financial impact of these mortgage loan interest rate factors. Prospective home buyers should keep these mortgage loan interest rate parameters in mind when assessing their home purchase opportunities, particularly in a rising interest rate environment.
