There are several possibilities for you to consider. A truly custom home would involve finding a lot, an architect, a builder. Finance would probably be a construction loan that would flip over to conventional financing when the home is complete. Plan on about two years for the project. If you like some of the national builders in your area (Pulte, Ryland, etc.) you might look at their plans and amend them to your taste. I am working with several buyers who have purchased in the area they want to live in and we are helping them rehab / remodel to their tastes. A professional Realtor can help you with any of these projects. Interview two or three Realtors, ask them about homes or projects similar to what you want to do, how they are involved, etc. Ask for references and check them. Ask the references about communication and follow-through. Call me anytime if you have questions.
