Think losing the mortgage interest deduction would be no big deal? We bust seven myths to show why the cost is bigger than you think.
Proposals floating on Capitol Hill to curb the mortgage interest deduction gloss over all the ways home owners, and even renters, would be hurt by the change. Let’s set the record straight.
Myth #1: The mortgage deduction is just for rich people.
- The mortgage interest deduction helps mostly middle- and lower-income families.
- 65% of families who use it earn less than $100,000 per year.
- 91% earn less than $200,000 per year (that’s where most economists draw the line between rich and middle-class).
- Only 9% earn more than $200,000 per year.
This myth may have arisen because of a related fact: If you buy a house, you’re much more likely to accumulate wealth by the end of your life. Home owners have an average net worth of $200,000, while the average renter’s net worth is $5,000, according to the Federal Reserve’s Survey of Consumer Finances.
- Raise property taxes. Not only will home owners pay more in taxes, renters won’t escape unscathed either as landlords raise rents to cover their costs.
- Cut services that everyone—renters and owners—enjoys.
Example: If you paid $10,000 in mortgage interest, and you’re in the 25% bracket, you’d pay $1,300 in extra taxes.
- The $10,000 deduction you have now saves you $2,500 on your taxes (25% x 10,000).
- The 12% credit would save you only $1,200 (12% x 10,000) on your taxes.
- In this scenario, if the mortgage interest deduction is changed to a 12% credit, you’d lose $1,300 (the current $2,500 savings minus the $1,200 you’ll save under the 12% plan).
The mortgage deduction is a key benefit to first-time home owners and trade-up buyers because you pay the most mortgage interest when you first take out a mortgage. (You won’t pay equal amounts of principal and interest until year 13 or later, depending on your interest rate.)
People with large families also get a lot of bang from mortgage interest deductibility—they buy relatively big houses for their big families.
Even if you don’t have a mortgage, getting rid of the MID will affect how much home you can afford to buy—and how much a buyer will pay for your home.
If you bought a home last year with a $200,000, 30-year, 5% fixed-rate mortgage and you’re in a 25% tax bracket, you’d save about $2,500 from the mortgage interest deduction alone in the first year you own your home. That’s money you can use to pay down other debts, save for your children’s college education, or put away to buy a move-up house.
If you’re at the beginning of your mortgage, losing the mortgage deduction will cost you a bundle:
- $26,685—a 15% drop in value for the median home valued at $177,900.
- A proportionally smaller gain in overall home equity over your lifetime, because your home now starts from a lower value.
