Exuberant Pricing? Time will tell

50 Sumner Road is back on the market for $4.450 million, 17 months after the owners bought it for $3.1 million in November 2019. The builders who totally rebuilt the place in 2017 put it up for sale that year at $3.6 before finally finding these owners in 2019 at the aforesaid $3.1, so some caution might be called for here.

I see from the listing that a pool was added recently. Otherwise, it looks about the same. Is a pool worth $1.3 million? I’m skeptical.
