I'd love to hear an example of one place where the city pays for any part of what a new developer is building...
I am currently developing 6 acres of raw land inside a city. Every cost is 100% mine to bear. I will pay for the roads/gutters/sidewalk which will be a gift to the city. They get to set the exact specification I must meet. Of course I will be installing the water, sewer, storm water, power, gas, phone, etc as well. The city provides absolutely nothing without a cost equal to or higher than their own cost. Continuing expenses like water and sewer come with continuing bills, is there a city that provides free water and sewer to anybody?!
100% of this cost goes to the developer, and then 100% is transferred to the buyer later on. That's just how this business works, pretty much everywhere. That's just to create dirt lots - not counting anything to do with building!
Building permits aren't insane here, a few hundred bucks, but you can bet the city is more than covering any costs they might incur. And of course every inspection comes with a fee. It cost them nothing to grant me permission to build on land that I already own, and in turn, they will receive more property taxes down the line for what was a piece of abandoned land.
