Why Real Estate Is a Bad Investment
I wanted the boring version of the answer: the numbers, the sources, and the actual arithmetic. Every input is underlined and linked to its source, and the computations are shown instead of hand-waved.
1. Over the last century, U.S. stocks have compounded at roughly twice the rate of U.S. home prices.
Aswath Damodaran maintains the standard 1928–present dataset of U.S. asset returns at NYU Stern, updated annually and sourced from S&P, FRED, and the Federal Reserve.1 If you use the geometric average, which is the compounding one and therefore the one that matters, the gap gets ugly pretty fast:
Important caveat, because this is where the argument usually gets slippery. Damodaran's real estate series uses the Case-Shiller Home Price Index, which tracks price changes only and does not include imputed rent.12 To compare total return to total return, meaning price appreciation plus rental income, the better peer-reviewed source is Jordà et al. (2019), in the Quarterly Journal of Economics, covering 145 years across 16 advanced economies.3
So even when housing gets the more generous rent-inclusive treatment, U.S. stocks have still beaten U.S. housing by a wide margin over the long run. This is not a small edge. This is the kind of edge compounding turns into a completely different life.
2. Home price appreciation is the headline, not the return.
The appreciation figure people quote at dinner usually skips the annoying part where houses require money every year just to continue being houses. Fannie Mae and most financial planners use a 1% to 4% annual maintenance-and-repairs reserve as the standard planning assumption.4 Add property tax and insurance, and the picture looks like this on a typical U.S. home:
The annual carrying cost alone is several times the long-run real appreciation rate of the underlying asset. The headline return exists. It just gets eaten before you get to feel especially clever about it.
3. Insurance is a structural drag, not a line item.
The U.S. Department of the Treasury's Federal Insurance Office analyzed 246 million policies and found that homeowners insurance premiums rose 8.7 percentage points faster than inflation from 2018 to 2022.8 The Harvard Joint Center for Housing Studies reports that real premiums rose roughly 20% between 2020 and 2023 alone, and 74% since the Great Recession.9 The Consumer Federation of America found premiums rose in 95% of U.S. ZIP codes between 2021 and 2024, with a third seeing increases of more than 30%.10 This is not a cute little line item. It is a ratchet, and most homeowners cannot opt out.
4. Selling a home is expensive, and the 2024 antitrust settlement barely moved it.
After the NAR settlement took effect in August 2024, buyer-agent commissions dipped briefly before rebounding, per Redfin's MLS analysis.11 So, okay, the old system got shaken. The round-trip cost is still rude:
5. Real estate is the opposite of diversified.
A typical homeowner holds one property, in one metro, at one price point, tied to one local economy and one labor market. An S&P 500 index fund spreads the same dollar across ~500 companies across every sector. The Jordà et al. dataset shows housing returns vary enormously by country and period; Japan's real housing returns have been negative for decades.3 The same concentration risk that would look unhinged in an equity portfolio gets rebranded as "the American dream" when the asset has a front door.
6. The "low volatility" story is partly a measurement artifact.
Real estate appears calmer than stocks in part because it is not continuously repriced. Equities are marked to market every second; houses are marked to market every several years, at transaction. Robert Shiller, whose Case-Shiller index is the standard measure of U.S. home prices, has noted that U.S. Census homeowner self-estimates imply a perceived ~2% annual real appreciation, while the actual measured figure is closer to 0.7%.2 The sense of steady growth is partly memory bias, which is very human and also not a return.
7. Leverage is a feature that cuts both ways.
A 20% down payment lets a buyer control 5× the asset, magnifying gains. The same leverage magnifies losses:
From its 2006 peak through 2012, the S&P/Case-Shiller U.S. National Home Price Index fell roughly 27%.15 Millions of U.S. households learned this distinction firsthand. Stocks can be levered too, but most investors choose not to, because they understand it is risky. Most homeowners do not describe their mortgage as margin, even though the math is sitting right there, wearing a little roof.
8. A primary residence is a consumption good that people keep calling an investment.
A primary residence produces no income, charges the owner every month to remain in it, and is paid for with after-tax dollars that could have been invested elsewhere. Calling it an investment muddies the accounting. It is housing that sometimes appreciates, not an appreciating asset that happens to include a guest bath. Assets that yield returns, like equities, bonds, or rental property run as a business, pay you. A primary residence charges you.
But what about...? The objections I would also raise.
I bought my house for $X and it's worth $4X now. How is that a bad investment?
ResponseProbably inflation, some appreciation, and the fact that you're comparing a leveraged purchase price to an unleveraged sale price. A $200,000 home bought in 1994 would be worth about $430,000 today from inflation alone, with no real appreciation at all.16 Most homeowners also do not net out the 30 years of property tax, insurance, maintenance, and mortgage interest they paid along the way. The Case-Shiller real (inflation-adjusted) appreciation rate from 1890 to 2024 is roughly 0.7% per year.2 Your house probably did fine. It almost certainly did not beat the stock market.
Rent is throwing money away. At least with a mortgage I'm building equity.
ResponseProperty tax, insurance, maintenance, HOA fees, mortgage interest, and transaction costs are also "thrown away." None of those build equity, and in the early years of a mortgage, interest is the majority of the payment. Meanwhile, a renter can invest the down payment and the difference between rent and full housing cost into index funds that have historically outperformed real estate. The honest question is not rent vs. buy. It is total housing cost vs. total housing cost plus the opportunity cost of the down payment. Whether owning wins depends on your rent-to-price ratio, how long you stay, and local appreciation. Slogans are not math, irritatingly.
A mortgage is forced savings. I'd never save that money otherwise.
ConcessionThis one is partly true, and worth honoring. For people who struggle to save, a mortgage is a commitment device that converts income into equity whether you feel disciplined that month or not. That is a real benefit. It just is not a financial argument that the asset is a good investment; it is an argument that the structure solves a behavior problem. The same person setting up an automatic transfer to a brokerage account would likely come out ahead, but many people do not do that (very understandable, we are all just little bundles of incentives in shoes), and for them a mortgage may genuinely be the better path.
What about the mortgage interest deduction and property tax deduction?
ResponseMostly not what it used to be. After the 2017 Tax Cuts and Jobs Act nearly doubled the standard deduction, the overall itemization rate fell from 30.6% in 2017 to 9.2% in 2021, per IRS data.17 The number of returns claiming the mortgage interest deduction dropped by 59% between 2017 and 2018 alone.18 For the roughly 9 in 10 U.S. households now taking the standard deduction, the mortgage interest deduction provides zero tax benefit. The 2025 One Big Beautiful Bill Act raised the SALT cap from $10,000 to $40,000 (phasing out for incomes above $500,000), which will restore some itemization for higher earners. For most homeowners, though, the old tax argument for ownership belongs to a different tax code.
Real estate is a great inflation hedge.
ResponsePartly true, partly overstated. Home prices do tend to rise with inflation over long periods, which is a real feature. But the carrying costs, including property tax, insurance, and maintenance, also rise with inflation, and insurance has recently risen faster than inflation. Stocks also hedge inflation over long periods, with higher real returns and without the concentration risk. Gold, TIPS, and I-bonds are more direct inflation hedges. Real estate works as a hedge. It is not uniquely magical at the job.
Legitimate reasons to buy a house anyway
None of this means "do not buy a house." I am not anti-house. I like a porch. I like a garden. I like the idea of painting a room a truly inadvisable color and being the only person who has to live with the consequences. A house is a home, and a home gives you things an index fund cannot.
Good non-financial reasons to buy include:
- Feeling settled. Not having to ask permission to live somewhere. Knowing you will not have to move because a landlord decided to sell.
- Making it yours. Paint the walls. Knock down a wall. Plant a garden that takes ten years to mature. Build the bookshelf into the alcove. Customize in ways a lease forbids, because leases are famously allergic to fun.
- Stability for kids. Same school, same neighborhood, same bedroom for years at a stretch. Continuity that matters in ways money can't quantify.
- Protection against rent volatility. Fixed-rate housing in a world where rents compound. The mortgage payment does not triple because your neighborhood got popular.
- Community and belonging. The neighbors you know by name. The coffee shop that knows your order. A place you return to, not a place you pass through.
- Pets, noise, hobbies, chaos. A life lived on your own terms, without a lease agreement in the background.
- The psychological security of ownership. Not a rational argument, but a real one. It matters to many people, and that's reason enough.
These are good reasons. They are just not financial reasons. The mistake is smuggling them into an investment thesis. That is how people end up stretching to buy more house than they should and calling it "putting money into an asset." Buy the house. Just know what you are buying.
