Know what you can afford. Since a pre-approval is based on your specific financial situation, it’s the key to understanding which homes to consider. Not only that, it tells anyone selling their home that you as a buyer have the ability to obtain a mortgage. Weichert Financial Services has licensed mortgage loan originators, called Mortgage Advisors, serving every Weichert office. The Mortgage Advisor is the only person you need to assist you with your mortgage every step of the way.
