The problem in Cedargrove is that most of the 4-family units are owned by one person. He buys cheap and if a developer wants to buy some, he wants some outrageous amount of money for them.
There is an organized community group there and they are vigilant in working with the housing inspector and town board members. If they didn't, the neighborhood would be a real hell hole.
The town does not have the money to buy up properties, tear them down and build new homes.
A few years ago there was a developer with a very aggressvie plan to tear down everything and rebuild the neighborhood. It was just too aggressive for the people living there and the plan fell through.
If you have any ideas, post them here. I would love to get some fresh ideas. Oh, by the way, I live in Cedargrove, so that's how I know so much about it.
