A Zestimate is a starting point, not a pricing tool. It’s generated by an algorithm that processes broad zip-code data, and in New Milford’s 06776 zip code, values range from $111,576 to $2,350,000. That spread makes automated estimates particularly unreliable here.A comparative market analysis, or CMA, is done by a licensed agent who reviews recently sold comparable properties near your home, evaluates what’s actively competing with you on the market, and accounts for property-specific factors the algorithm can’t see, things like Candlewood Lake access, acreage, septic condition, recent renovations, and neighborhood character. The difference between a Zestimate and a CMA can easily be tens of thousands of dollars in either direction.
