How do you get the best mortgage deal?

We have been pre-approved by a mortgage company. The mortgage company has recommended a real estate agent. I am a little leary of going with this real estate agent, however, because, being a first time home buyer, I need a lot of guidance. I am afraid that, being tied to the mortgage broker, the real estate agent might not fight to get us the best mortgage deal (if it happens to be with a company other than the original mortgage broker’s).
How do you go about getting a good mortgage deal?
first of all, the real estate agent is not there to get you a deal on a mortgage – that is either your responsibility or the mortgage broker’s responsibility. The agent is there to put you in a house (show you houses, explain the offer/acceptance routine, be there at closing and walk you through the purchase process).
If you do not trust you mortgage broker to get you a fair deal, then you can start calling around to banks in your area and inquire about their rates. This means, however, getting a new pre-approval and starting from scratch on the mortgage. Being a first-time buyer, if you go this route, you are going to have to educate yourself regarding rates and points and buy-downs.
from what i hear, and i work for a bank, a broker is the worst way to go because you are spending alot of money for not much service. I just bought my first home and couldn’t have done it without my real estate agent. I would apply through lending tree.com (there are a few banks that will actually compete for your business) I would also look into credit unions as well. dont forget you get the 8k for first time home buys from obama!
Do not use their recommended realtor. Use one that you select.
