Housing Ratio

Step1: Calculate Housing Ratio

Lenders use two ratios to approve the amount they will lend you:

housing ratio
debt-to-income ratio

The "housing ratio" is calculated by dividing monthly housing expenses by your gross monthly income. The housing ratio should not exceed 28%.

Monthly housing expenses includes real estate taxes, insurance, etc. If you don't have your real estate tax or insurance figures, the American Housing Survey shows that the median taxes paid averaged $12 per $1,000 in home value (divided by 12 months). The property insurance paid averaged $30 per month.

You may contact your local community and county officials to determine your true county and city tax factor: www.statelocalgov.net

Private Mortgage Insurance (PMI) will be required if your down payment is less than 20% of the home purchase price. Your PMI monthly cost will average 0.005 of the borrowed amount divided by 12.

If you fail to pass either ratio, you may need to adjust your loan request to bring your ratios within approved parameter

Housing Ratio (should be around 28%): %

Step 2: Calculate Debt-to-Income Ratio

Debt-to-Income Ratio (should be around 36%): %
