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.
Over 30 years, Wisconsin guy is paying around $140,000 in interest and $120,000 in taxes. Assuming he's in the 28% tax bracket, his "out of pocket" cost for interest & property tax is ~ $187,000 over 30 years.
Alabama guy will pay about $93,000 in interest and $15,000 in property taxes, a total of ~$108,000. Assuming he's in the same 28% bracket, he's "out of pocket" only $78,000, a net savings of $109,000 over Wisconsin guy. If he invests these savings – plus the lower down payment – for 30 years, he’ll end up WAY ahead of Wisconsin guy.
It’s Wisconsin guy who should be jealous.
As for only being able to write off less interest . . . well, boo hoo, Alabama guy is PAYING a lot less. Complaints like this remind me of the people who were already off the tax rolls complaining that the Bush tax cuts “. . . didn’t help them.”
