Hi Ed -
It is a wise decision to go into a new development with your own agent. I would be happy to repreresent you in the purchase of any new construction home as a Buyer's Agent. You need an agent who will take you through the entire process from negotiation to your final punchlist and to the closing table.
Give me a call today and we can discuss the best plan of attack for your purchase. I have been an Associate Broker in Scarsdale for over 10 years and you can see all of my credentials by going to my website @ http://www.cindyschwall.houlihanlawrence.com.
Our brokerage also hold the lions share of the market in Scarsdale and lower Westchester.
Thanks and I look forward to hearing back from you.
