Following the steps below will result in a calculation of
two sets of figures. These represent the low and high
extremes of the mortgage amount you may qualify for.
- Take your total monthly income from all sources and
multiply it by .28 and also .40. (These are the low and
high extremes that in fact are percentage of your income.
You should use both numbers)
- Subtract your monthly debts. (This should include all
personal debts including credit cards, car payments and
child support.) This will give you the amount of your
income that you have left for your monthly house payment.
- Find out what your property tax and insurance will
equal if paid in twelve monthly installments. Subtract
this from the total arrived at in #2. (You may get these
figures from an insurance agent and the local government
offices where you are thinking about purchasing a home.)
This will leave you a net mortgage amount that you can
afford. (Principal and Interest).
- Multiply this amount by 12 months. This will give you
your annual mortgage payment.
- Divide this amount by the current average interest
rate. You may find this out from your local lender. For
example: if the rate is 7 1/4%, you would use .0725. The
result of this final step will give you the amount of a
mortgage that you are likely to qualify for.
- Now add the amount that you have saved for a down
payment and this will give you the approximate price of a
house that you can afford.
