Most lenders require that you spend
no more than 28% of your gross income on your
mortgage,
taxes, and insurance. They fear if too much of your income
goes toward housing, you face a greater risk of not making
your mortgage payments on time.
Keep in mind that if youre married
and buying a house jointly with your spouse, both of your
incomes count. If youre not married but buying with
a partner, you may want to look for a lender who will consider
both incomes.
