18 Sandy Lane is a decent enough house just off Round Hill Road. It has some Merritt noise but it also has 4 acres and a pool. The owners tried selling it for $2.995 million ($624 per sq.ft.) back in 2007 and have now dropped it to $1.825 million ($391 sq.ft.). Apparently, the market for somewhat dated homes with relatively low ceilings and a touch of highway noise is … limited. There was a time, not so long ago, when this price would reflect the land value: buy a lot, get a house free. Now, who knows?
