If you actually place a deposit on a lot in order to build, you are "allowed" to change your mind once and only once only to purchase another lot OR you are "allowed" to transfer your deposit to a SPEC home. We met with our sales agent to design our home and during that few days of lot selection we kept looking at SPEC homes to see flooring, trim packages, appliances and cabinets. We were about to drop off a check for our lot of choice in order to build then went to see one more home that was "just released" for sale that day. We liked that home very much so the sales agent put that SPEC home "on hold" for us for a couple of hours. We went out for lunch then decided to buy the SPEC home.
