Begin by looking through the various rates offered by different Sunnyvale mortgage lenders so you have an idea of the deals that are being offered. You should also research and become familiar with lending terminology so that you are aware of the different types of mortgages in order to decide which one is right for you. The dealers will of course talk you through this but it is important to also do your own research so you understand the terms of each type of mortgage offered.
Another possible option is to hire a broker who will do your shopping around for you. However, they will not necessarily find you the best deal and some brokers are not as impartial as they claim to be. Using a broker that is recommended by friends or family or employing the services of a broker alongside your own research are good strategies to take.
A couple of the larger lenders located in Sunnyvale, CA are the Wells Fargo Home Mortgage company located at 308 West El Camino Real, Sunnyvale, CA 94087-1306 and the Bank of America which can be contacted at 444 S Mathilda Avenue, Sunnyvale, Ca 94086. The biggest companies are not always the best and you may be able to find cheaper deals with smaller companies but they make a good point at which to start your search.
Another strategy is to ask your real estate agent to recommend some lending companies. Agents will have experience with knowing which Sunnyvale mortgage lenders offer the best deals to their clients and sometimes are able to offer better rates than you could find by searching on your own.
