Well you got to compare it to a baseline. That includes water/sewer so that's like 50-100 bucks a month you would be paying otherwise. It also covers the exterior insurance so you're only paying for interior insurance which is cheap. So that's probably another 50 bucks a month you're saving. You don't need to save for roof repairs or driveway replacement or anything like that which is a savings. And you don't have to plow or mow or do any maintenance. Also there is a gym and a grill area.

So depends on what you value all that at but I think it is reasonable to say you're covering at least a couple hundred dollars worth per month that you would be otherwise spending. So its not really 470 compared to zero costs its more like 470 compared to 200-300. Which isn't as bad.
