OK, let me be perfectly clear (to borrow a line from our president which means "I'm about to really lie to you").
Two guys with the same incomes and the same home, but one lives in AL and the other in WI. The house belonging to the guy in Alabama cost him $100,000 after his $20,000 down payment, and he owes $100,000. He pays $500 a year in property taxes.
The guy in Wisconsin paid $150,000 for the same house after his $30,000 down payment, and he still owes the $150,000. He pays $4000 a year in property taxes.
Both have mortgages at 5%. The guy in Wisconsin will be able to deduct 50% more in interest over the course of his 30 year loan, because his mortgage is 50% larger. He'll also be able to deduct $4000 in property taxes. The guy in Alabama will only be able to write off two-thirds as much in interest over the course of the 30 year loan, and he'll only be able to deduct $600 a year in taxes.
Everything else being equal, the guy in Alabama is paying more to bring in the necessary tax revenues than is the guy in Wisconsin.
