This document discusses how to calculate total housing costs. It includes calculating the mortgage payment using multipliers or formulas based on the loan amount, interest rate and term. Property taxes are calculated as a percentage of the home value and affect total costs. Homeowner's insurance and maintenance are estimated at around 1% of the home value annually. Total housing costs equal the mortgage payment, taxes, insurance and maintenance minus any tax deductions. An example calculates all costs for a homeowner to determine their total monthly costs.
