“How much can I borrow for a mortgage” is the most commonly asked question among first-time borrowers. Unfortunately, there’s no one simple answer. The amount you can borrow depends on numerous factors, including your income, credit card debts, and your credit score. Aside from checking your creditworthiness, most lenders will ask you for a downpayment and to pay for mortgage premiums. All of these factors can impact your mortgage size, so you should consider using a mortgage calculator to check your buying power.
