I live in the Grove area of West Roxbury, MA. I've been here since 1994. When I moved in, almost all of the houses in the Grove had cesspools. I still do. I have watched house after house sell for half the price just because no one wanted to buy the houses with the failed systems. Then a flipper would buy the house, connect to the city or put in a new system and sell the house for market value. A recent example, my neighbors sold their house for $212k in 2018 to a flipper who turned around and sold it for $515k. You definitely want to upgrade your system, yourself. I would prefer to flip my own house, thank you. t
