it is a problem when one buys a home one can afford, lives in said home for years, and then the homes value goes up exponentially, which means the property taxes go up exponentially as well. Now the once affordable home, even if paid off, is no longer affordable. The "huge profit" they receive for selling there home doesn't help them because all of Denver housing has sky rocketed and again, they can't afford the taxes.

The flaw is thinking that people want to leave or are happy about selling their homes. They are not.
