Qualifying Ratios Help

This calculator is useful to estimate what the banks will be looking for when you apply for a home loan. There are certain percentage ratios of your debt to your income which you need to fall into in order to qualify. Also, the last calculated field shows the monthly income you would need to qualify for a home with the Sale Price you have entered (given the other monthly debt you will also be asked to enter). Thus you can estimate a realistic price range of Homes you should look at, but filling in your pre-existing debt and income and varying the Sale Price you enter.

How to use this calculator.... Enter values by tabbing between fields. You can change all, some or none of the default values in the Variable Fields column before pressing the Calculate button.
