Before you begin house-hunting, it's best to know from your lender if you pre-qualify or are pre-approved for a loan. The distinction between the two is that pre-qualifying determines how much a lender will lend you. It involves obtaining a letter from the loan officer who looks at your debt ratios, gross income, and work history to see if you're qualified to make the monthly payments. This usually can take weeks while you wait for a pre-qualifying letter.

Pre-approval, on the other hand, takes it a step further and usually involves non-refundable fees. This process takes into consideration your credit history report, income verification, confirmation of down payment, and ability to pay closing costs. Once approved, the pre-approval letter lets the real estate agent and seller know you're qualified to negotiate terms.
