Dear Mr. David Kemler,
If you do not have an agent that you are working with as a "buyer's agent and would like representation, I would be happy to work with you.
I can negotiate and show you any listings that you are interested in Chappaqua.

All the best!

Use one of the local real estate sites and you can find this pretty easily. Why do you want their number? Get your own agent and have them set it up. From a lot of posts on this site, it seems there is pretty much no chance of saving the commission as a buyer by not coming in with an agent so you should at least have someone on your side to do the leg work.

Both are listed with Prudential Holmes & Kennedy which is right in the village of Chappaqua. Phone number is (914) 238-3988. We had a good experience with Tory Miller in that office but ultimately we decided we weren't really interested in a commute that long and decided to get out of the market. Good luck.
