Mortgage Calculation


All lenders, typically focus on TDS (Total Debts Service Ratio) or GDS (Gross Debts Service Ratio) calculation for qualifying the mortgage application. The TDS ratio is maximum to 44% for most lenders. Different lenders use different qualifying rates and TDS Max Ratios to evaluate the mortgage applications. This is why the maximum mortgage amounts are different for different lenders. Here we introduce some useful formulated online calculators:
