To be honest I always recommend to my prospects that the FIRST thing they do is get pre-qualified. It doesn't cost you anything, it doesn't committ you to anything and it doesn't hurt your credit. In our quickly changing mortgage marketing it can save you a lot of suprises.
I'm sure you are already on the internet looking at homes in your price range. If not feel free to use the search on the homepage of my webstie. No registration required.
If you aren't already working with an agent I'd be glad to meet you and talk through the various options with you. Have you already been qualified by a local lender? This is your true first step.
