I think that the listing and selling agent for a property at 45 Trefry was Keller Williams Realty Boston North West (978) 369-5775 List Agent: Lori Megee. (MLS # 71197108) She would be most knowledgable about the neighborhood's particulars. Ask her for a CMA. The sale price in June of 2011 for #45 was $740K. This home is slightly larger than the tax records show #28 is.
