There are a million mortgage lenders and brokers in Chula Vista and the surrounding San Diego county. This is a really personal choice that people, often times, don’t give enough thought to. You should be comfortable with your lender, it’s a big choice and you shouldn’t leave it to just some guy recommended by your real estate agent. Often times real estate brokers have a sister company created to capture this business (points on your loan), this skirting the edge of conflict of interest. Your best bet is to check with your bank or if you have a credit union you belong to and see what they offer. You’ll live with this choice until you refinance at some point in the future so do your best to make a good choice upfront.
