If you go to the listing agent directly, you will have no advocate at all. Your best bet is to find a professional who can walk you through the process of buying a home. Someone who will keep your information confidential and negotiate on YOUR behalf. Don't make the number one mistake first time home buyers make. Find a BUYER AGENT to protect your interests. Feel free to read more about it on http://www.hometeamadvantedge.com or google buyer agency, or buying a home in Massachusetts. Good luck.
If I can be of any help, please let me know. Thanks and good luck,
