The housing market is a stagnant pond, and everyone is blaming the wrong chemical.
Lately, there is a loud, desperate push to "unlock" inventory by cutting capital gains taxes on home sales. The logic is surface-level: if we stop "punishing" people for selling their homes, they will finally list them, and the supply crisis will vanish. It sounds like a win-win. It sounds like common sense.
It is a catastrophic misunderstanding of human greed and market mechanics.
Proponents of the More Homes on the Market Act want to double the tax exclusion for sales—moving it from $250,000 to $500,000 for individuals. They argue that the "lock-in effect" is purely financial. They believe Grandma is sitting in a five-bedroom house she hates because she’s terrified of the IRS taking a slice of her $400,000 profit.
They are wrong. Grandma isn’t staying because of the tax; she’s staying because she has a 2.5% mortgage and nowhere better to go. Cutting taxes won't create a "flood" of inventory. It will create a bonfire of asset inflation that burns the very first-time buyers it claims to help.
The Myth of the "Tax-Locked" Seller
The "lock-in effect" is the industry’s favorite boogeyman. It’s a convenient narrative for real estate agents who want more commissions and developers who want higher prices. But let’s look at the actual math.
Under current law, $250,000 ($500,000 for married couples) of your primary residence's gain is already tax-free. If you bought a home for $300,000 and it’s now worth $800,000, and you’re married, you pay exactly zero dollars in federal capital gains tax.
The people pushing for these cuts aren't trying to help the middle class. They are trying to help the ultra-wealthy in coastal enclaves where property values have spiraled into the stratosphere. We are talking about the top 1% of the top 1% of homeowners. Giving them a tax break doesn't "unlock" a starter home for a teacher in Ohio. It subsidizes a luxury move for a venture capitalist in Palo Alto.
When you subsidize the seller, you don't lower the price for the buyer. You give the seller more ammunition to bid up their next property.
Subsidizing the Top, Starving the Bottom
Basic economics dictates that when you increase the after-tax proceeds for a seller, that money doesn't just sit in a savings account. It goes right back into the housing pool.
Imagine a scenario where every homeowner in a high-growth city suddenly gets an extra $250,000 in their pocket upon selling. Do you think they’ll use that to buy a cheaper house and pocket the change? No. They’ll use that extra leverage to outbid everyone else for the limited "downsize" options or the next tier of luxury homes.
This isn't theory. We've seen what happens when the government pours liquidity into a supply-constrained market. Whether it’s low interest rates or tax incentives, the result is always the same: Asset Inflation. By cutting the tax, you are effectively increasing the purchasing power of current owners while doing nothing for those who don't yet own. You are widening the wealth gap with a chainsaw. The "inventory" that supposedly hits the market will be priced even higher because the sellers know their neighbors have more cash to burn.
The Real Problem is the "Golden Handcuffs" of Interest Rates
The industry wants you to look at the IRS because they don't want to talk about the Federal Reserve.
The true "lock-in" isn't the capital gains tax. It’s the $1.5 trillion in "interest rate subsidies" that existing homeowners are currently enjoying. If you have a 3% mortgage and the market rate is 7%, you are effectively receiving a massive monthly check from the bank just for staying put.
A tax break at the point of sale is a one-time sugar high. It doesn't solve the structural problem that moving from a $2,000-a-month mortgage to a $4,500-a-month mortgage for the exact same quality of life is a bad trade.
If we actually wanted to move the needle on inventory, we wouldn't be looking at tax cuts. We would be looking at Portability. Why can’t a homeowner take their 3% interest rate with them to a new property? That is the friction. The tax is a rounding error compared to the cost of debt. But the banking lobby would never allow portable mortgages—it would decimate their ability to reset loans at higher rates. So, instead, they lobby for tax cuts, which sounds "pro-homeowner" but actually just pumps the bubble.
The Brutal Truth About Supply
"People Also Ask" online: Will lowering capital gains taxes make houses more affordable?
The answer is a resounding, brutal No. Supply is not a tax problem. Supply is a zoning and labor problem. We have spent forty years making it illegal to build anything other than single-family McMansions in the places where people actually want to live.
When you have a massive shortage of units, the price is determined by the maximum amount the wealthiest buyer can pay. If you give that buyer (the seller of the previous home) a tax break, you just increased the "maximum amount."
If you want more houses, you need more hammers and fewer "Neighborhood Character" meetings. You don't need to give a windfall to someone who has already seen their net worth double just by sitting on a couch for a decade.
The "Fairness" Trap
There’s an emotional argument being used here: "It’s my money, why should the government take a cut of my home's growth?"
I've seen people lose their minds over a $20,000 tax bill on a $600,000 profit. They call it an injustice.
Here is the counter-perspective: Capital gains on a home are the most "unearned" wealth in the modern economy. You didn't invent a product. You didn't manage a team. You didn't provide a service. You simply existed in a location that became desirable due to the collective investment of the community—roads, schools, businesses, and safety.
By taxing that gain, the government is recapturing a portion of the value created by the public and using it (theoretically) to fund the very infrastructure that made the house valuable in the first place.
If we eliminate that tax, we shift the burden of funding society onto people who actually work for a living—those paying income tax—while rewarding those who simply own assets. It is a direct transfer of wealth from the young and productive to the old and sedentary.
Stop Trying to "Fix" the Market with Giveaways
The housing market doesn't need more "incentives" to sell. It needs a reality check.
We are currently in a standoff between sellers who refuse to acknowledge that the era of "free money" is over and buyers who simply cannot afford to participate. Tax cuts won't break that standoff. They will only embolden the sellers to hold out for even higher prices, knowing they’ll keep more of the loot.
If you want to actually "unlock" the market, do the opposite of what the lobbyists suggest:
- Tax Vacancy, Not Sales: If a home is sitting empty as an "investment," tax it until it bleeds. Force that inventory into the hands of people who will actually live in it.
- Eliminate the Step-Up in Basis: Currently, if you die and leave your house to your kids, the capital gains are wiped clean. This encourages hoarding real estate until death. If you want to see homes hit the market, tax the gain at the moment of inheritance.
- Kill 1031 Exchanges for Corporations: Stop letting institutional investors roll their profits into more and more single-family homes without ever paying the piper.
The "More Homes on the Market Act" is a wolf in sheep's clothing. It is a gift to the wealthy disguised as a solution for the desperate. It treats the symptoms of a fever by turning up the heat.
If we want a healthy housing market, we have to stop treating homes like tax-advantaged brokerage accounts and start treating them like places to live. That means letting the tax code do its job: disincentivizing the runaway accumulation of wealth at the expense of everyone else.
Don't ask for a tax cut. Ask why you're being told a tax cut for the rich will somehow make your rent cheaper. It never has, and it never will.
Stop waiting for the "unlock." It's not a lock; it's a price tag. And it just went up.
