Mortgage Prequalification Calculator | Jim Ngo - Ontario, CA

Mortgage lenders use Debt To Income (DTI) Ratios to analyze your mortgage payment and determine how much loan you qualify for. The Front Ratio compares your total Housing Expenses to your Monthly Income, including Principal & Interest, Property Tax, Mortgage Insurance, and anything relating to your home. The Back Ratio compares your total Monthly Debt plus your Housing Expenses to your Monthly Income.

Conservative Debt To Income (DTI) ratios are 31/43. Aggressive ratios are 37/47. Some loan program will allow ratios to go up to 50%, but anything above that will likely be denied.

Use my calculator to compute your monthly payment and your Debt To Income Ratios. Simply CLICK the appropriate section and enter the purchase price, down payment, expected rate of interest, your monthly income and debt.

6 Things Not To Do When Applying For A Mortgage

When lenders review your application, they like to see consistency in your finances.

  • Do not make major purchases like furniture, appliances, jewelry, vehicles or vacations
  • Don't change or quit your job
  • Consult with your mortgage professional before withdrawing, depositing, or moving large amounts of money in or out of your bank account
  • Do not pay off debts or collections (unless instructed to do so by a mortgage professional)
