The City of Austin has never supported financing any percentage of any true sports stadium. All the minor leagues are now based in its suburbs. The O2 MLS team stadium cost of over $250 million to build was financed entirely by the team. But the land it sits on is owned by the City of Austin.
It bought the land in 1995 for $1.4 million. It is leasing the land to the team for $550,000 per year over 20 years.

The City will get a very nice return of $11 million over the next 20 years from an initial investment of $1.4 million.
So I am strongly suggesting that the City has for all practical purposes spent $0,000,000.00 building professional sports stadiums.
Why does anyone think there will be any changes in the future?
