The best way for you to get a great deal with a builder is to have Buyer Representation with an agent that has experience dealing with builders. Since my father was a home builder, I know how to negotiate with a builder. Also, it depends on whether the builder is a local builder or a large, national chain. Either way, I can definitely help you get a great deal on a new home from a builder. Just helped another couple recently buy a home from Lennar and they got a fabulous deal! We even negotiated for them to use their own lender because it was more beneficial for them to do so. Call me anytime at 443-243-1832 or email me at firstname.lastname@example.org. I would certainly be my pleasure to help you get a great deal on a new home from a builder.
FYI...builders have some very difficult contracts that most consumers do not understand. Those contracts are written to their (the builder's) advantage. It is important for you to have the proper representation when you decide that you want to buy a home from a builder. Without an agent that has experience with builders, you are taking a risk.
