permag, I agree with anabeth. Use your realtor to connect you to a local mortgage company. However, you should check with wellsfargo since you already have a relationship with them. Your realtor will have a great feel for which company would be the best fit for you though. The reality is even if you go with a small mortgage company, they are going to sell your mortgage to a large bank within the first 6 months to a year anyway. My last mortgage was done through a small company out of Odessa and once finalized, was promptly purchased by Wellsfargo.
Here's some advice from an old ag who has been around the block a few times: 15 year (will save tens of thousands over a 30 year), "FIXED RATE" (rates haven't been this low since the 1950's/ DO NOT get a variable rate), payment no more than 25% of your take home pay.
Rates are going up, get r done.
