I use to live in that area, WOW they have done an excellent job on the project. However I would not recommend anyone to purchase property unless you are represented by a realtor. We receive approx. 10 calls or emails a week with problems between a buyer, builder, developer. Realtors also know more about the markets. A Dallas real estate agent can run the comp's for the area to determine if you are getting the best price per sq. ft based on other markets, also many times we know of specials the Dallas new home builder or Dallas developer offers to Dallas real estate agents that is not offered the general public.
Keep in mind IF SOMETHING goes wrong you fall under Dallas real estate agent e & o insurance policy
Contact our office if I can provide you further assistance, we also offer a Dallas home buyer rebate program earn $1000s' at closing.
