Ray, The first two things you need to do are find out if this lot will work for what you are looking to do, and make sure it is not too small or has heritage trees, etc., and also get pre-approved with a lender. If you are not yet working with a Realtor, give me a call and I will try to walk you through what needs to be done. It is not a simple process, but I have gone through it with other clients and developers as well.
