Married, two kids, & I was 27. My mortgage is with Countrywide which is a huge company but you can get to know them by name at a local office.
The advice I would give you is to find a buyer's realtor. Most realtors concentrate on listings only but it doesn't cost you a penny more to use a realtor. Your buyer's realtor and the seller's realtor split the commision. In a hot market there is talk about seller's realtors steering the seller away from other realtor's to avoid splitting the commision but I think that is rare. Look in the newspaper and check out realtor signs in areas you are interested in. A local realtor that is popular in my neighborhood has a link to the MLS on her web site which I'm sure doesn't make her very popular with her peers but I like it. I look on their for homes in my area to see what they are selling for. I like to say that following the market is a hobby of mine but my wife says I'm just nosy.
Back to the realtor. When I started looking we gave him the parameters. He selected 4 houses to show us. We looked at all four but purchased the first one he showed us. He'd learned that much about what we wanted by spending a few minutes with us. He drove us to a couple of appointments with the lender, drove us to the closing and wanted a picture of us opening the door the first time so he was there for that too.
