These townhomes are only available thru the builder and are not listed in the Multiple Listing Service. I would highly recommend that you use a realtor you like and trust and go with the realtor to visit the development so that the realtor can sign in. The realtor can help you work thru the purchase and make sure you get all you are can get from the builder. You will never get a "better deal" without having a realtor.
Let us know if you would like any more help in this matter.
