Buy-to-Let vs Stock Market: Which One Grows Your Money Faster?
£1 put into a rental property in 1996 became £22.30.
£1 put into the S&P 500 became £22.05.
That is a 25p gap after 30 years. Property crossed the line first, but only just, and the last five years have been a very different race.
Let's find out buy-to-let vs stock market.
Quick take
Over 30 years, buy-to-let edged the S&P 500 and left the FTSE 100 and gold well behind.
Over the last 5 years, stocks won comfortably: 75% versus 41%.
Landlords earn their extra return with extra work. Index investors earn slightly less with almost none.
Key terms in 30 seconds
Buy-to-let (BTL): buying a property to rent it out. The first dedicated BTL mortgages launched in September 1996.
S&P 500: a scoreboard tracking 500 of the largest companies listed in the US, such as Apple and Microsoft.
FTSE 100: the same idea for the 100 largest companies on the London Stock Exchange.
Index fund: a fund that holds every company in an index, so one purchase spreads your money across all of them.
Total return: growth in value plus income, whether that income is rent or dividends.
Dividends: slices of company profit paid to shareholders. "Reinvested" means used to buy more shares.
ISA: a UK account where your investment growth is shielded from tax.
Buy-to-let vs stock market: the 30-year scoreboard
Who won?
Buy-to-let, by a whisker. Here is what £1 invested in September 1996 was worth by September 2026, according to research from estate agency Hamptons:
Investment | £1 became | Total return |
Buy-to-let | £22.30 | 2,130% |
S&P 500 | £22.05 | 2,105% |
FTSE 100 | £8.96 | 796% |
Gold | £7.36 | 636% |
The landlord figure counts price growth plus rent after running costs. The S&P 500 figure assumes dividends were reinvested. Rent did the heavy lifting: 62% of landlord returns came from tenants, 38% from rising prices.
Is 25p a real win?
Barely. £22.30 versus £22.05 is a gap of roughly 1.1%. The figures are also a market-wide average built from official UK house price and rent data. Your flat, your mortgage, your tax bill and your empty months will write a different number.
Could you copy the 1996 landlord today?
The entry ticket has changed. The average UK home cost £54,900 in 1996, which is about £114,400 in today's money. It now costs just over £270,000, according to HM Land Registry.
Buy-to-let vs stock market: who is winning now?
The tables have turned. Cumulative returns over the last 5 years:
S&P 500: 75%
FTSE 100: 73%
Buy-to-let: 41%
What changed for landlords? Two things.
Prices went sideways. House prices boomed in the pandemic, then slipped, and growth turned negative in 2023 and 2024.
The rules got tougher. Since 1 May 2026, landlords in England can no longer evict a tenant without a reason (the old "Section 21" route). Possession now needs a legal ground under "Section 8", which generally means more evidence and more waiting.
Are landlords finished? No. Five years is a short window. It does mean a landlord starting today faces different maths from one who started in 1996.
Buy-to-let vs stock market: what does it cost you in effort?
Returns are half the story. Effort is the other half.
Buy-to-let | Index fund | |
Entry cost | A property deposit (27% of the price on average today) | Whatever you choose to invest |
Time | Ongoing: tenants, repairs, cleaning | Very little: buy, hold |
Biggest headache | Empty months mean zero rent | Prices can fall |
What does a landlord actually sign up for?
Fixing faulty appliances, cleaning between tenants, renovations to keep the place desirable, and the risk of a destructive tenant. A property management agency can take the load, for a fee. One flat is manageable. Several can become a full-time job.
And the index fund?
Buy it, hold it inside an ISA, wait. It is cheap and easy, though stocks carry risk too.
Which should you choose?
Buy-to-let could suit you if you have a large deposit, enjoy hands-on work (or will pay an agent), and can handle empty months and changing rules.
An index fund could suit you if you want to start small, stay hands-off, and spread your money across hundreds of companies at once.
Nothing stops you from doing both over time.
The verdict
Thirty years. £1. A 25p gap.
One path needs tenants, tradespeople and a high tolerance for the phrase "the boiler has stopped again." The other needs an account, an index fund and patience.
Same finish line, very different commutes.
