How much mortgage can I afford?
To calculate how much house you can afford, we take into account a few primary items, such as your household income, monthly debts (for example, car loan and student loan payments) and the amount of available savings for a down payment. As a home buyer, you’ll want to have a certain level of comfort in understanding your monthly mortgage payments.
While your household income and regular monthly debts may be relatively stable, unexpected expenses and unplanned spending can impact your savings.
A good affordability rule of thumb is to have three months of payments, including your housing payment and other monthly debts, in reserve. This will allow you to cover your mortgage payment in case of some unexpected event.
