My point is you have correlation, but not causality.
You have to look at the total tax burden - not only income tax. All States provide more or less the same services for a very similar cost, so what they are not raising in income tax they have to bring in with other taxes.
Texas for example is famous for no income tax, but they are one of the highest in both sales tax and property tax, so all things considered Texas is pretty average.
Florida's total tax burden is one of the lowest in the country, but the cost of living is not. And it's about to go up quickly because of property insurance.
Here is a cost of living index, FL is on the higher end.
But that is not the whole story either.
You also have to consider income. If you make more money you can afford more. Not to pick on FL, but they make a really good example, because while their cost of living is on the high end the average income is one of the lowest.
BTW, I am in Milwaukee. And one of the reasons why Wisconsin is quietly and slowly gaining popularity in every moving statistic is because you have a moderate cost of living, but good income, a moderate climate without extreme weather patterns, heat or stroms and plenty of fresh water from the Great Lakes. And a high quality of living, that's why our number one migration is from Chicago and Illinois.
Is that impacting real estate prices? Looks like it does, Redfin says Milwaukee was the #1 hottest real estate market in the US in February with a 20% increase in median price. I have to add: February was an outlier, we are realistically at about half of that.
