Gift funds and down payment sources

For a fixed-rate mortgage, the APR is locked in at closing and will not change. For an Adjustable-Rate Mortgage (ARM), the initial APR is fixed for a set period, but after that, it can fluctuate based on the index and margin outlined in your loan agreement.

The numbers on the Loan Estimate are estimates. Some costs can change, while others cannot. For example, the interest rate is only locked if you have specifically received and paid for a rate lock. Certain fees, like the lender’s origination charge, are also subject to a “zero tolerance” rule, meaning they cannot increase at closing unless your application changes.

APR allows you to compare loans from different lenders on a like-for-like basis. Because it includes both interest and fees, a loan with a slightly higher interest rate but lower fees could have a lower APR, making it the less expensive option overall.

Pre-qualification is a quick, informal estimate based on unverified information you provide. Pre-approval is a much more rigorous process where the lender checks your financial background and credit, giving you a definitive, conditional commitment that carries significant weight with sellers.
