Mortgage Calculator – How Much Can I Afford?
Mortgage companies use something called qualifying ratios to determine how much they’ll lend you. Most mortgage companies use either a 28/36 ratio or a 25/33 ratio. The first number in each pair is the percentage of your gross income that the lender would consider acceptable as a monthly mortgage payment (i.e. if you make $3,000 per month, 28% of that is $840 per month).
The second number in each pair is used when all debt payments are considered, not just the mortgage. (i.e. if you make $3,000 per month, but also have a $250 a month car payment, 36% of $3,000 is $1,080, minus the $250 car payment equals $830). As you can see, in this example the numbers work out to be almost the same. Obviously if you have more debt you would qualify for less.
