Frequently asked questions
What are the 28/36 rules?
The 28% rule states that your total housing expenses (including mortgage payment, property tax, and insurance) should not exceed 28% of your gross monthly income. The 36% rule states that your total monthly debt payments (including housing and other debts) should not exceed 36% of your gross monthly income.
Why is my affordable price lower than expected?
The calculator subtracts property tax and insurance from the allowable housing payment, which reduces the amount available for principal and interest. Also, if you have other monthly debts, they reduce the back-end limit.
Can I afford a more expensive home if I have a larger down payment?
Yes, a larger down payment increases the affordable price because you need to borrow less, and it may also reduce your monthly payment, allowing you to qualify for a higher price.
