Realestate.com published a fun blog looking at the possible correlation between Super Bowl appearances and that city’s median home prices and found this out:

Of the 10 NFL teams that have appeared in the Super Bowl the most, seven are from cities with high median home prices, when compared to the national median home price. The opposite is also true; the 10 teams that have been to the Super Bowl the least, if they have even gone at all, generally come from cities with low median home prices.
