It's a matter of degree. There's reasonable return, unreasonable return, then there's Eversource-level greed.I mean, isn't asking for $1 more than the developer's loan payments outright greed? If the market won't bear it, they won't charge it.
It's a $75 tax on pets and they give you nothing at all for it. The market may bear it but it's a bad look for the developer (not that they care). The next thing could be something like charging a user fee for the elevator!
