Estimate Your Buying Power


<<Back to Buyer Information


Lenders use two standard (but somewhat flexible) guidelines to determine how much of a monthly mortgage payment you can afford. The first guideline is that your household should spend no more than 28 percent of its gross monthly income (before taxes) on monthly housing expenses, including: mortgage principal and interest, hazard insurance, real estate taxes and private mortgage insurance, if applicable. However, some lenders will stretch that figure to 33 percent.

The second guideline is that your monthly household expenses (as outlined above) plus other debt should not exceed 36 percent of your gross monthly income, although some lenders will stretch this to 38 to 40 percent.

How can I estimate how much of a monthly mortgage payment I can afford?
First, calculate your monthly household income, including that of your co-borrower, if you have one. In addition to regular wages, don’t forget to include overtime, bonuses, commissions, dividends/interest, alimony/child support and any other income.

A. Your Maximum Allowable Housing Expense
After you total your gross monthly income, multiply it by 28 percent to get your maximum allowable housing expense.

1. Gross Monthly Income $
2. Multiply By 28%                        x  28%
3. Your Maximum Allowable Monthly Housing Expense $
 
B. Your Debt
Now, determine your debt. Credit cards, car payments, student loans, alimony or child support should be included here, as should any debt incurred by your co-borrower, if you have one.
1. Installment and revolving debts (credit cards) $
2. Car Loans $
3. Student Loans $
4. Alimony/Child Support $
5. Other Long-Term Monthly Debts $
                                     
Total Debt $
 
Now that I know this, what can I afford relative to my overall debt?
Most lenders generally will allow you to allocate up to 36 percent of your household income to overall debt, although some lenders will allow you to go up to 40 percent under the right circumstances, including a larger down payment. You can calculate your maximum allowable combined housing and monthly debt in the space below:
1. Your Total Gross Monthly Income $
2. Multiply By 36%                        x  36%
3. Your Maximum Allowable Combined Housing and Monthly Debt $
