Subsidies & Tax Policy

The federal government spends heavily to make housing affordable. Most of that money reaches the demand side of a market that cannot expand supply. That is the definition of an inflationary subsidy.

The short answer

When supply is fixed, a subsidy to buyers is captured by sellers. This is not a controversial result; it is the standard incidence analysis, and it holds whether the subsidy arrives as a tax deduction, a loan guarantee, a voucher, or cash at closing.

Research on down payment assistance finds a $25,000 subsidy raises home prices about 4.1%, costing buyers roughly $177 billion to deliver about $100 billion of benefit. The gap is not waste in administration. It is capitalization into land and house prices.

The supply-side subsidy that builds expensive units

The Low-Income Housing Tax Credit is the main federal program that actually produces units, at roughly $13.5 billion a year. It also produces them at around $480,000 each in California, more than the median home. The structure rewards the syndication of credits rather than the delivery of cheap housing, and the beneficiaries are disproportionately the developers and investors who monetize the credit.

Section 8 vouchers run the same experiment on the demand side: over $30 billion a year entering constrained local rental markets, where a meaningful share is absorbed by rent rather than by tenants.

The mortgage machine

Behind the visible programs sits the financing apparatus: Fannie Mae and Freddie Mac's guarantees, the Federal Home Loan Bank System's $1 trillion in advances, the FHA's insurance, and the conforming loan limit that rises almost every December, to $832,750 for 2026, with little scrutiny.

Each of these expands the quantity of credit chasing a fixed housing stock. The 30-year fixed-rate mortgage itself, often described as a market institution, is a New Deal construction now backing roughly $13 trillion in debt.

Taxes that freeze the market

Not every tax raises revenue at the expense of supply by accident. Assessment caps of the Proposition 13 type reward staying put and penalize moving, pulling homes out of circulation. Transfer taxes charge households for the act of relocating. Both reduce the turnover that lets housing stock match household needs.

The instructive counter-case is the land value tax, which Milton Friedman called the least bad tax precisely because it cannot discourage the thing being taxed: land does not move, and taxing it does not penalize building on it.

The Demand Trap: How Down Payment Subsidies Inflate the Housing Prices They Promise to FightResearch shows a $25,000 down payment subsidy would raise home prices 4.1%, costing buyers $177B while delivering only $100B in benefits. Friedman's logic explains why.
The Mortgage Interest Deduction: A $30 Billion Subsidy That Benefits the WealthyThe mortgage interest deduction costs taxpayers $30 billion annually but primarily benefits high-income homeowners. Research shows it doesn't increase homeownership. It increases home prices.
The SALT Subsidy: How Federal Tax Policy Entrenches the States That Have Made Housing UnaffordableThe SALT deduction overwhelmingly benefits California, New York, and New Jersey, the same states with the worst housing affordability. That's not a coincidence.
The LIHTC Illusion: How America's $13.5 Billion "Affordable Housing" Subsidy Builds Homes No Poor Family Can AffordThe federal Low-Income Housing Tax Credit costs $13.5 billion a year yet produces units priced at $480,000 each in California. A free-market analysis of why the program enriches developers, not tenants.
The Section 8 Paradox: How Housing Vouchers Inflate the Rents They're Meant to SubsidizeThe Section 8 voucher program spends $30B+ annually yet inflates rents in low-income markets. A free-market analysis of demand-side housing subsidies.
Fannie Mae & Freddie Mac: How Government Mortgage Guarantees Inflate Home PricesHow Fannie Mae and Freddie Mac's government-backed mortgage guarantees inflate housing demand, socialize risk, and drive up home prices while taxpayers bear the downside.
The Federal Home Loan Bank System: America's Hidden $1 Trillion Housing Finance SubsidyThe Federal Home Loan Bank System provides over $1 trillion in government-backed advances to member banks, inflating mortgage demand and housing prices for 90 years. A free-market analysis.
The Conforming-Loan Ratchet: Why Higher Federal Loan Limits Cannot Fix Housing Affordability on Their OwnFHFA raised 2026 conforming loan limits to $832,750, but supply data and mortgage-rate evidence show why bigger loan ceilings cannot solve affordability alone.
The 30-Year Fixed Mortgage: How Government Engineered America's Housing Finance System — and Why It FailedThe 30-year fixed-rate mortgage is not a market invention. It's a New Deal government creation. Today it backs $13 trillion in debt and helps inflate the very prices it promised to lower. A free-market analysis.
The Property Tax Lock-In: How Assessment Caps Freeze Housing SupplyProposition 13-style property tax assessment caps trap long-term homeowners in place, removing millions of homes from market circulation and driving up prices for everyone else.
The Moving Tax: How Real Estate Transfer Levies Freeze Housing Supply and Hit Working Families HardestReal estate transfer taxes promise easy revenue for affordable housing, but the data show they suppress supply, trap families in place, and devastate the very budgets they claim to fix.
Taxing Land, Not Buildings: Milton Friedman's Radical Fix for America's Housing CrisisProperty taxes penalize construction and reward idle land-banking. Friedman called land value taxation 'the least bad tax.' With home prices 54% above 2020 levels, it deserves a hearing.
