If you're a USAA member they have a nice program that'll set you up with a realtor. Also includes cash incentives (or did when we bought 2.5 years ago)
I checked out lots of houses online, primarily sawbuck.com as well as the various realtor sites. Make yourself a list of what all you want in a house (how many beds, bathrooms, etc) and a realtor can probably hook you up with some houses that fit the bill. I know in my neighborhood we have 3 (town)houses or so up for sale right now but I can't for the life of me find listings for them anywhere!
