Put £100,000 into UK residential property over the last 25 years and your total return would have landed somewhere around 6–8% per year. Put the same money into global equities and you’d have seen 8–10%. On paper, stocks win by a couple of points. But those headline figures leave out two things that flip the outcome completely: property’s ability to borrow against it, and stocks’ ability to hide from the taxman inside an ISA.

That last number — £20,000 — is the hole card stocks hold. Put equities inside an ISA and you pay no income tax on dividends, no capital gains tax, and you never have to report a thing. Property has no equivalent wrapper. Its advantage is different: you can buy a £400,000 house with a £100,000 deposit, and if the house goes up 10%, your cash has gone up 40%. That kind of leverage simply doesn’t exist in the stock market for individual investors.
So which one actually wins? The answer depends entirely on your tax band, your time horizon, and whether you want to manage tenants or trade from your phone. Twenty focused investing tips for UK investors cover a lot of ground, but this comparison comes down to a handful of specific numbers. Here’s what you actually need to know.
What the Long-Run Numbers Actually Show
The first thing to land on is a term you’ll see everywhere in this discussion. Leverage means using borrowed money to increase your exposure to an asset. In property, a 75% mortgage turns a 5% price rise into a 20% gain on your deposit. It also turns a 20% price fall into an 80% loss on your equity. That asymmetry is the single most important difference between these two investments.
What I tend to notice when running the numbers for people is that the leverage effect is so large it can mask everything else. A geared property portfolio can look unbeatable in a rising market, then turn punishing when rates go up or prices stall. Worth keeping that balance in mind as we dig into the rates. Compounding is every investor’s ultimate weapon, but leverage accelerates compounding in both directions.
What the Rate Comparisons Actually Tell You
The most direct way to compare property and stocks is to line up their rates side by side — return, cost, time, tax. The table below does that for a straightforward case: a buy-to-let held directly vs a global equity portfolio held inside an ISA. No leverage on the property side yet; that comes after.

| Metric | Direct Buy-to-Let | Global Equities (ISA) |
|---|---|---|
| Long-run total return (unlevered) | 6–8% per year | 8–10% per year |
| Income yield (net of costs) | 3–5% rental yield | ~3.5% dividend yield |
| Entry cost | SDLT + 5% surcharge | 0.5% Stamp Duty Reserve Tax |
| Time commitment | 2–15 hours per month | Minutes per month |
| Time to sell | 3–6 months | Same day |
| Tax wrapper available | No | ISA (£20k/yr) and SIPP |
| Leverage available | 75–80% LTV typical | None for individual investors |
Notice the big gaps are not in return rates — they’re in costs, time, and tax treatment. The property entry cost (Stamp Duty at 5% on top of the normal rate for a second home) is ten times the equity entry cost. The time commitment difference is measured in hours vs minutes. And the tax wrapper difference can be worth thousands per year to a higher-rate saver.
Now add leverage. Put down a 25% deposit on a £400,000 house and a 5% price rise gives you a 20% return on your £100,000 equity — before any rent. Over 15 years, that same £100,000 deposit on a house growing at 4% per year could build to around £520,000 in equity, which works out to roughly 11.7% compound annual return on your original cash, plus net rental income on top. The same £100,000 in a FTSE tracker returning 7% real would reach roughly £276,000 over the same period.
That leverage effect is why the property-accelerator analysis shows buy-to-let potentially beating stocks by several percentage points on equity returns. But the catch is hiding in plain sight: those numbers assume the property keeps rising and the mortgage stays affordable. Structuring rental property tax-efficiently becomes critical when Section 24 limits mortgage interest relief to a 20% tax credit, which hits higher-rate landlords especially hard. A geared landlord at 40% can end up paying more tax on rental income than the net cashflow coming in.
Where Property and Stock Investors Lose Money
Overlooking the Section 24 tax trap
Since 2017, mortgage interest on buy-to-let has stopped being a deductible expense. Instead, landlords get a 20% tax credit on the interest. A higher-rate taxpayer (40%) who pays £10,000 in mortgage interest on £20,000 of rental income used to deduct the full interest and pay tax on £10,000. Now they pay tax on the full £20,000 and get a £2,000 credit — so their tax bill roughly doubles. Many geared landlords discovered this only when their first self-assessment landed. The fix for some has been to hold property inside a limited company, which still allows full interest deduction, but that means higher Stamp Duty on transfer and ongoing company filing costs.
Ignoring liquidity until it’s too late
Stocks inside an ISA can be sold and the cash in your bank account the same day. Property takes 3–6 months from instruction to completion in England, and longer in a falling market. The 5–8% transaction cost (estate agent, legal, survey) also means you need a significant gain just to break even on a quick sale. If you might need access to your money inside five years, property carries a hidden cost that doesn’t show up in the annual return figures.
Assuming the ISA allowance will always be there
The £20,000 annual ISA allowance is generous but not guaranteed. Past governments have reduced it. Max it out while you can. If you don’t use your allowance in a given tax year, you lose it permanently.
Forgetting to account for time
Property management at 2–15 hours per month adds up. Over a decade, that’s 240–1,800 hours. At a modest £20 per hour of your time, that’s £4,800–£36,000 of implicit cost that never appears in a return calculation. Stocks require minutes per month. For anyone whose time has value, that difference alone can tip the scales.
How to Match the Investment to Your Situation
If you’re in the 20% tax band and have time to manage a property
A basic-rate taxpayer suffers less from Section 24 (the 20% credit roughly matches their tax rate) and pays 18% CGT on gains instead of 24%. Rental income taxed at 20% also compares reasonably to dividend income taxed at 8.75% inside a general account. If you’re comfortable with the hands-on work and have a long time horizon, leveraged property can generate strong equity growth and steady cashflow. The worked example from the research: a £400,000 house with a £100,000 deposit, £300,000 mortgage, rent of £1,800 per month, and net cashflow around £300 per month after costs and basic-rate tax via a limited company.
If you’re in the 40% or 45% band and value simplicity
Higher-rate taxpayers get hammered by Section 24 and pay more tax on rental income. For them, the Stocks and Shares ISA is the clearest winner — £20,000 per year growing entirely tax-free, with no reporting, no Stamp Duty beyond 0.5%, and full liquidity. The dividend allowance of just £500 (from April 2024) means even small portfolios outside a wrapper face tax. Maxing the ISA allowance every year should probably come before any direct property investment.
If you want to do both — which most serious investors do
Property gives you leveraged real-asset exposure and rental income that can replace a salary. Stocks in an ISA give you a diversified, liquid, tax-free growth engine. The typical split I see among experienced investors is property for the wealth-building leverage and stocks for the safety net. Smart portfolio diversification in the UK usually means running both channels and rebalancing as circumstances change.
What’s changing next
Two developments worth watching. First, Capital Gains Tax rates for property and other assets were equalised at 18% and 24% from 30 October 2024 — so the old property CGT penalty is gone. Second, Making Tax Digital for Income Tax is rolling out, and landlords with gross rental income above the threshold will need to file quarterly digital updates. That’s an administrative cost property has and stocks don’t. The fundamental tax wrapper advantage for equities hasn’t changed, but the gap on exit costs has narrowed.

The Real Winner Comes Down to Leverage vs Tax Wrappers
The numbers don’t declare a single winner because the decision isn’t about the asset class — it’s about which structural advantage matters more for your specific finances. Property gives you leverage that can multiply gains over a long hold, and it generates rental income that can be substantial relative to dividends. Stocks inside an ISA give you tax-free growth that compounds undisturbed, with liquidity that means you’re never locked in when life changes direction.
The investors I see who do best on this question are the ones who stop asking “which is better” and start asking “which advantage do I need right now.” If you have a long time horizon, a tolerance for hands-on work, and you’re in a lower tax band, leveraged property can build wealth faster. If you value simplicity, liquidity, and tax efficiency — especially as a higher-rate taxpayer — the ISA is a hard proposition to beat.
