I should raise the rent on my house in Chicago.
Another interesting statistic would be the percentage of household income paid for housing costs.
I recently did see this, perhaps linked from zillow, and was shocked/not shocked. California is the worst, but it’s the same typical blue urban areas/states, and the cause is usually high taxes.
When we moved to north florida several years ago, at about the pit of the housing collapse (especially bad in florida), no way we could have rented. It was only affordable to buy one of the sad foreclosures.
Such a statistic should state whether it is a before tax or after tax percentage.
