Cairo is in central Greene County and like the rest of the county, it is hard to give a figure since housing varies so much. The closer to Windham Mtn you are, the higher the price, the better the views, the higher the price, etc.
Mary I live in Cairo township and can tell you that it is very convenient being only 15 minutes from the thruway and Catskill shopping, yet with gorgeous scenery.
I list and sell homes all over the county so if you're interested, give me a call - 518.965.0600
