Americans move. A lot. We celebrate the freedom of movement as a core national ideal, but if you look past the pioneer mythology, you see something else at work: a financial system engineered to keep us perpetually unsettled.
While countless forces contribute to this restless churn, one of the most destructive and least-understood is the holy cow of American homeownership: the Mortgage Interest Deduction (MID).
It’s often touted as a massive benefit for homeowners, a pillar of the “American Dream” that helps regular folks afford a home. I’m here to tell you that this tax break is a statistical joke for most homeowners, a systemic cruelty to renters, and a highly effective community destabilization program disguised as policy.
The Tax Break for Banks, Not Buyers
Let’s dismantle the biggest myth first: you do not get a tax break for buying a home. You get a tax break for taking out a loan.
The MID allows homeowners to deduct the interest paid on their mortgage (up to a certain limit) from their taxable income. Here’s why that matters:
Standard Deduction Killer: Since 2017, the standard deduction has been high enough that the majority of homeowners—over 90%—don't itemize their deductions. This means for most people, the MID provides zero financial benefit at tax time. It’s vaporware.
Debt-Dependent: For the small percentage of wealthy homeowners who do itemize, the largest tax benefit occurs during the first few years of the loan when 90% of your payment goes to interest. As you pay down your principal and actually get closer to owning your home, the interest portion shrinks, and the tax break vanishes.
This is the central absurdity: our housing policy financially rewards citizens for being in debt and financially punishes them for being financially stable. The winners are not the homeowners, but the banks who receive a government-subsidized guarantee that debt servicing will remain a desirable, even necessary, component of middle-class life.
The Perverse Incentive to Churn
The real urban tragedy of the MID, however, is the perverse incentive it creates to constantly sell and move.
Imagine a family ten years into their 30-year mortgage. They have successfully hammered away at the principal, reducing their debt and increasing their equity. They are establishing deep roots, their kids are in school, and the community is benefiting from their stability.
But look at their taxes. Their MID benefit is now negligible.
What happens next? The unspoken, corrosive logic of the system kicks in: "If we sell this house, buy a new one, and take out a brand new, huge loan, we can restart the clock! Back to that beautiful, interest-heavy phase where the government subsidizes our debt!"
This policy actively subsidizes churn—the continuous selling of homes to reset the loan/interest cycle—at the expense of stability. It turns the primary home into a tax-advantaged investment vehicle rather than a bedrock of family and community life. You cannot build a durable, resilient neighborhood if the system is constantly nudging residents toward the next down payment and the next round of high-interest debt.
Decoupling Housing from Debt
We need to abolish the Mortgage Interest Deduction and replace it with a policy that recognizes the fundamental human need for stable shelter, regardless of whether that shelter is owned or rented.
The idea of a universal housing deduction or credit is the single best starting point. Instead of subsidizing the lending industry, we should:
Implement a Universal Housing Credit: Give every household, whether they rent or own, a fixed, refundable tax credit (not deduction) based on the cost of housing in their metro area. This would provide genuine, equitable financial relief to renters—who are disproportionately low-income and receive zero benefit under the current system—and would offer an actual, simple benefit to homeowners without tethering it to debt.
Focus on Principal, Not Interest: If we must offer a housing incentive, it should be a one-time tax credit tied to the principal paid or the down payment made, or targeted only to first-time, low- and moderate-income buyers. This targets wealth creation, not debt maintenance.
We must stop treating housing as a tax gimmick and start treating it as the foundational requirement for social and urban health. The fact that the MID continues to exist is proof that American policy often serves entrenched financial interests above the common good. We need to tear down the walls of debt and start building stable, financially liberated communities.
