Property vs Equities: Which Produces Better Long-Run Returns?

Few arguments in personal finance are more passionate — and more poorly grounded — than the property versus equities debate. Property investors point to their doubled house prices and rental income. Equity investors cite the long-run superiority of global stock markets. Both sides are partially right, and both routinely make the comparison in ways that favour their preferred conclusion. This guide attempts a fair, rigorous assessment.

The UK Property Return Record

UK residential property prices have risen dramatically over the long run. Average UK house prices increased from approximately £22,000 in 1980 to approximately £285,000 in 2026 — a nominal increase of roughly thirteen times. In real (inflation-adjusted) terms, the increase is more modest but still significant: UK house prices have roughly tripled in real terms over 46 years.

Adding rental income, the total return from UK residential property (capital appreciation plus net rental yield) has been substantial. Gross rental yields on UK residential property have typically ranged from 3 to 6%, depending on location and property type. After maintenance (typically 1 to 2% of property value per year), management fees (10 to 15% of rent), insurance, and voids (typically 3 to 6 weeks per year), net yields are considerably lower — often 2 to 4% in most UK markets.

But there are several important caveats that complicate the headline figure:

Survivorship bias: published property price indices track the average. They do not capture the properties in declining areas that have underperformed significantly, the failed landlords who exited the market and are no longer counted, or the periods of local market decline that national figures obscure.

Leverage effect: property returns are routinely quoted as if the investor owned the asset outright, when most buy-to-let investors have used mortgage financing. A £100,000 deposit funding a £250,000 property that rises to £300,000 looks like a 50% return on the deposit — but this is a leveraged return, not a comparison of unlevered property versus equity. Leverage works both ways: in a declining market, the same investor faces a loss far exceeding the percentage decline in the property value.

The Section 24 and stamp duty era: the UK tax treatment of residential property investment has deteriorated significantly since 2015. The stamp duty surcharge on additional properties (introduced at 3% in April 2016 and increased to 5% from 31 October 2024) raises the entry cost materially. Section 24 of the Finance Act 2015 restricted mortgage interest relief to the basic rate of tax (phased in from 2017/18 and fully in effect from 2020/21), which makes buy-to-let economically unviable for many higher-rate taxpayers who use mortgage financing.

The Equity Return Record

Global equities have delivered strong long-run returns. The MSCI World Index, measuring developed market equities with dividends reinvested, has returned approximately 10 to 11% per annum in USD terms over 30 years to 2026. In GBP terms, the number varies with currency movements but has broadly been in the 8 to 10% range.

UK equities (FTSE All-Share) have underperformed global equities significantly over the past decade, driven by the index's heavy weighting in financials, energy, and mining — and an absence of the major technology growth companies that drove US equity returns. FTSE All-Share total returns have been approximately 7 to 8% per annum over 20 years.

US equities (S&P 500) have outperformed all other major developed markets: approximately 10 to 11% per annum total return in USD over 20 years. Past performance is not, of course, a reliable guide to future returns.

Critically, equity return figures are typically quoted as unlevered returns. Unlike property, where leverage is common and largely invisible in return comparisons, equity return data represents money in at the start and money out at the end — no leverage assumed.

The Apples-to-Apples Problem

Comparing property and equity returns is surprisingly difficult to do fairly:

Leverage asymmetry: most property investment is leveraged; most equity investment is not. A fair comparison requires either comparing both on an unlevered basis, or both on an equivalent leveraged basis. Leveraged equity portfolios (using margin lending or CFDs) amplify returns in the same way as a mortgage — but most personal finance comparisons of property vs equities ignore this and compare leveraged property to unlevered equities.

The use-asset advantage (and complication): owner-occupied property is simultaneously an investment and a home. The imputed rental income (the rent you save by owning rather than renting) is a real economic return — economists include it in property return calculations even though it does not appear as cash income. This makes owner-occupied property look somewhat better than pure investment property. However, it also means you cannot separate the investment decision from the lifestyle decision.

Transaction costs: these are dramatically different. Buying a property in the UK costs approximately 3 to 5% all-in (stamp duty, legal fees, survey). Selling costs approximately 1 to 2% (agent fees). Round-trip transaction costs of 4 to 7% are enormous — they require years of holding just to break even on the purchase. By contrast, buying a global equity ETF costs essentially nothing (no stamp duty on most ETF purchases, very low brokerage). The liquidity and transaction cost advantage of equities is enormous and rarely factored into property return comparisons.

Diversification: a £500,000 residential property is concentrated in one building, in one street, in one town. If the local employment base deteriorates (a factory closure, a town declining) or if the property has structural problems, the investor faces losses that a diversified portfolio would never experience. A £500,000 global equity ETF is diversified across thousands of companies, dozens of countries, and hundreds of sectors.

The Tax Comparison (Post-2016 UK)

The relative tax treatment of property and equities in the UK has shifted substantially in favour of equities since 2015:

For equities held in an ISA: gains and income are entirely exempt from UK tax. The ISA allowance of £20,000 per year allows substantial tax-free accumulation over time. A long-term investor maxing the ISA from age 25 to 65 could accumulate significant assets with no UK tax on gains or income.

For equities in a SIPP: contributions receive income tax relief (at the marginal rate, potentially 45% for additional-rate taxpayers). Growth is tax-deferred. Withdrawals after age 55 (rising to 57 from 2028) are taxed as income, but 25% of the pot can be taken as a tax-free lump sum.

For residential property (since 2016):

• Stamp duty surcharge on additional properties (5% since 31 October 2024, up from 3%) raises entry costs.
• Section 24 mortgage interest restriction means only basic rate (20%) relief on mortgage interest — higher-rate landlords with mortgages face a materially higher effective tax rate.
• CGT on residential property disposals: 18% (basic rate taxpayer) or 24% (higher/additional rate) from October 2024.
• No equivalent to ISA/SIPP tax protection.
• Furnished holiday lettings tax advantages were removed from April 2025.

The practical result: for investors who have the ISA and pension capacity to shelter equities, the effective tax rate on equity returns is dramatically lower than on property returns, even before considering the Section 24 and stamp duty burdens.

What the Evidence Tells Us

A careful reading of the evidence yields several conclusions:

Over very long periods (30+ years), global equities have outperformed residential property on a total return, unlevered, comparable basis — when transaction costs, tax, and management burden are properly accounted for. Several academic studies reach this conclusion, including the work of Jordà, Schularick, and Taylor (2019) on long-run returns across 16 countries, which found that equities and housing returned broadly similar risk-adjusted real returns over 145 years, with local variation.

Property outperforms in specific local conditions: in supply-constrained markets (Central London, certain coastal towns) and over periods where leverage was readily available at low cost, buy-to-let has been exceptional. This is real, but it depends on timing, location, and leverage availability that cannot be assumed to persist.

The diversification benefit of equities is large and structural: an equity investor can achieve full global diversification; a property investor cannot. This difference in risk profile matters more than is usually acknowledged.

Property has genuine inflation-hedging properties: rental income tends to rise with inflation; property values over very long periods correlate with inflation. This is a genuine advantage in inflationary environments (as 2021-2023 demonstrated).

What This Means for HNW Internationally Mobile Investors

Most internationally mobile high-net-worth investors benefit from holding both asset classes. The optimal question is not "property or equities?" but "what balance, in what structures, for what reasons?"

A coherent allocation might include:

• A globally diversified equity portfolio (through ISA, SIPP, offshore bond, or GIA depending on tax position) providing liquidity, diversification, and income.
• Direct property in one or two markets (potentially combining lifestyle benefit with investment — a home abroad, a UK base) providing inflation protection and real asset exposure.
• REITs (Real Estate Investment Trusts) providing liquid, diversified property exposure within an equity portfolio structure — accessible through ISA/SIPP wrappers.

The specific balance depends on: current and expected future tax position; whether property provides a lifestyle benefit (holiday home, foreign residence) in addition to investment return; liquidity needs; risk appetite; and the investor's ability and inclination to manage direct property.

The value of investments in equities and property can fall as well as rise. Past performance is not a reliable guide to future returns. This guide is for information purposes only and does not constitute financial, tax, or legal advice. Seek professional advice before making investment decisions.
