Getting a pre-approved mortgage is a great way to get started on buying your new house. With a mortgage approval, you will be in a better position to negotiate with sellers on the purchase of your new home. You will also be able to close on a property quicker than other buyers. This shows the seller how serious you are about the property, and it will make the seller more comfortable working with you. In a "seller's market," or where supplies are limited, a pre-approved mortgage is essential in purchasing your dream house.
