The slogan compares the wrong two numbers. Do it properly and the case for buying rests almost entirely on a mechanism nobody says out loud — one that also happens to be the strongest argument against renting.
“Renting is throwing money away” is repeated as though it were arithmetic. It is not. It compares your whole rent cheque against your whole mortgage payment, and treats the second as savings.
The correct comparison is rent against the costs of owning that you never get back: mortgage interest, property tax, insurance, maintenance, depreciation, and transaction costs spread over however long you stay. Economists call this user cost, and a standard treatment in the Journal of Economic Perspectives puts it at roughly 5 per cent of the home’s value per year. The paper names the error directly: the conventional mistake is to treat “the purchase price of a house as if it were the same as the annual cost.”
Where housing returns actually come from
You have probably seen the finding that housing has matched or beaten equities over the long run. It comes from a study of 16 advanced economies from 1870 to 2015: real total return on housing 7.05 per cent a year, equities 6.89 per cent, at half the volatility.
Two things about that.
First, the composition. The same paper finds that long-run real capital gains on housing are around 1 per cent a year. Essentially all of housing’s return is rental yield. For an owner-occupier, that “yield” is the rent you don’t pay — which is precisely what the renter in the comparison is paying. Net it out and about one point a year of real appreciation is what’s left.
Second, and this matters for an American audience: in the United States specifically, equities won decisively. Real returns full-sample: 8.39 per cent equities against 6.03 per cent housing. Post-1980: 9.09 against 5.66. The “housing beat stocks” headline is a sixteen-country average, and the US is one of the places it does not hold.
How slowly houses actually appreciate
Robert Shiller’s long-run US index, running back to 1890, implies real appreciation of about 0.7 per cent a year. Independent work across 14 countries puts the US below 1 per cent annually since the 1890s.
That figure is contested. A 2024 study rebuilt the series from millions of newspaper listings with quality controls and found more appreciation — real prices roughly four times their 1890 level by 2006, about 1.2 per cent a year — along with a finding that real rents rose around 60 per cent, reversing a companion stylised fact. It is a working paper and its own method has selection questions.
Both sides agree on the order of magnitude: somewhere around one per cent real, per year. Now set that against round-trip transaction costs of about 7 per cent. Buyer’s-agent commissions, according to Federal Reserve analysis, moved only from about 3 per cent in the late 1990s to 2.7 per cent in 2022–23, and totalled around $170 billion — 0.6 per cent of GDP — in 2024.
Seven per cent of costs against one per cent a year of gains is why a break-even horizon exists, and why it is measured in years rather than months.
The horserace
Someone ran the comparison properly. A 2012 study in Real Estate Economics pitted a buyer — 20 per cent down, 30-year fixed, realistic taxes, maintenance and selling fees, eight-year hold — against a renter who invested the down payment and every month’s cost difference. Across 1978 to 2009, US aggregate plus four regions and 23 metros:
Renting and reinvesting produced more wealth in 64.6 per cent of realised eight-year holding periods. For the US as a whole, the renter’s portfolio finished 26 to 46 per cent above the owner’s net sale proceeds.
That result is period-specific — 1978 to 2009 contained an extraordinary equity bull market — and the authors’ own index is explicitly designed to flip as conditions change. It is not a law.
The finding that cuts against renters
The same researchers’ follow-up is the more important paper, and almost nobody covers it. They decomposed what actually drives the outcome.
Appreciation barely matters. A 20 per cent higher appreciation rate moves the probability that renting wins from 75.6 per cent to 62.2 per cent.
What dominates is behaviour. If the renter fails to invest the monthly difference, the result inverts completely: buying wins about 84 per cent of the time, and the renter’s terminal wealth ratio collapses from 1.37 to 0.70.
Their conclusion is worth quoting: “buying a home can result in more wealth because it forces households to save more than they would otherwise.”
That is the mechanism. Not appreciation — enforcement. A mortgage is a savings plan you cannot skip, with a tax subsidy and a rent hedge attached.
The strongest case for buying
Fairness requires it. A 2018 analysis computed returns on home equity for a median home bought at the end of 2002 — internal rates of return of 10 to 14 per cent even without itemising deductions, beating bonds at every horizon.
The same authors are explicit about who loses: a buyer purchasing in 2007 would have done far worse than the stock market, and among first-time low-income borrowers, 40 to 50 per cent were unable to sustain homeownership for five years, with divorce a major factor. Low-priced homes are also the most volatile, concentrating risk on the buyers least able to absorb it.
There is also one genuinely causal study. When Stockholm privatised municipal rental blocks into co-ops, county boards approved some near-identical buildings and rejected others on essentially arbitrary grounds — a natural experiment. Treated households gained roughly 800,000 kronor in net worth within four years. The mechanism there was leveraged capital gain, not forced saving; consumption actually rose. It is 38 co-ops in one booming Swedish market, and may not transfer.
What the slogan gets right
Renting genuinely is risky — a point the pro-renting case tends to skip. Research on rent risk puts it plainly: “the conventional wisdom that homeownership is very risky ignores the fact that the alternative, renting, is also risky.” Owning hedges that. The hedge is already priced into what you pay, and its value scales with how long you stay.
So what should you actually ask?
Not “am I throwing money away.” Three better questions:
- How long will I stay? Seven per cent of transaction costs amortises only over time. Short horizons favour renting almost regardless of anything else.
- What is the price-to-rent ratio here? This is the actual valuation anchor. It has ranged from a stable 18–20 times between 1960 and 1995 to a record 28.6 times at the end of 2006. It varies enormously by city and it moves the answer more than national averages do.
- Will I actually invest the difference? Answer this honestly, because it is the variable that flips the result. If the answer is no, the mortgage is doing something for you that you would not do for yourself — and that is a real benefit, not a fake one.
The honest version of the sentence is not “renting is throwing money away.” It is: renting only works if you have the discipline a mortgage would have imposed on you. Most people don’t. That is a much better argument for buying than the one everyone makes, and it is the one the research actually supports.
