If you had £50,000 to invest today, would you put it into a buy-to-let flat or a FTSE 100 tracker? It’s a question plenty of Brits are asking right now. UK residential property has historically risen in value by around 5% per year, and with rental income added, total returns can hit roughly 8% annually. Meanwhile, UK stocks have delivered returns of 7% to 9% per year over similar periods. On paper, the numbers look close. But the real difference isn’t the headline return — it’s what happens after tax, costs, liquidity, and timing are factored in.

Property and stocks both have a place in a portfolio, but they work very differently. One gives you leverage and a tangible asset you can live in. The other gives you liquidity and tax wrappers that can make a huge difference to your net return. Here’s what you actually need to know.
What This Comparison Actually Comes Down To
When people compare property and stocks, they often focus on which one “performs better.” What I tend to notice is that the real question is which one fits your situation — your cash, your timeline, and your tolerance for hassle. The two assets are not competing on the same playing field.
The Full Cost Picture: What You Actually Pay
Headline returns are misleading because they ignore the costs that are unique to each asset class. With property, the purchase price is never the only number that matters. Stamp duty, legal fees, survey costs, and mortgage arrangement fees add thousands before you even own the place. For a non-resident buying UK residential property, there’s an additional 2% surcharge on top of standard SDLT rates, and from 6 April 2025, investment properties attract a further 5% surcharge — up from 3%.
Once you’re a landlord, the costs keep coming. Mortgage interest for individual landlords is restricted to a 20% basic-rate tax reducer under Section 24, and from 6 April 2027 that reducer rises to 22%. That means higher-rate taxpayers can’t deduct their full mortgage interest from rental income — a major hit to net yield. Rental income itself is taxed at your marginal rate: 20%, 40%, or 45% for 2026/27, and from 6 April 2027 at separate rates of 22%, 42%, and 47%.
Stocks have their own costs, but they’re much smaller. Stamp Duty Reserve Tax on UK shares is 0.5%. Platform fees and dealing commissions are typically under 0.5% per year. And if you hold shares inside an ISA, there’s no tax on dividends or capital gains at all. The annual ISA contribution limit is £20,000.
What this means in practice: a property that rises 5% in a year might look good, but after stamp duty, legal fees, Section 24 restriction, and CGT on disposal, the net return can be half that. A stock portfolio returning 7% inside an ISA keeps nearly all of it. The gap between gross and net is where the real comparison lives.
If you’re unsure how the tax rules apply to your specific situation, it’s worth getting tailored guidance. A service like Financial Advisor can help you run the numbers on your own portfolio.
Where People Get This Wrong
Ignoring the Section 24 mortgage interest restriction
Many landlords assume they can deduct their full mortgage interest from rental income before tax. Since 2017, that hasn’t been true for individual landlords. You only get a basic-rate tax reducer — 20% of your mortgage interest, rising to 22% from April 2027. For a higher-rate taxpayer with a £10,000 mortgage interest bill, that’s a £2,000 reducer instead of a £4,000 deduction. The difference can turn a profitable rental into a loss-making one on paper.
Forgetting the 60-day CGT reporting rule
When you sell a residential property in the UK, you must report the gain and pay the tax within 60 days. Miss the deadline and you face penalties and interest. Shares sold outside an ISA are reported on your annual self-assessment — no 60-day clock. I’ve seen landlords caught out by this, especially if they sell late in the tax year and assume they can wait until January.
Overestimating liquidity
Property transactions take weeks or months and incur 3–8% in agent and legal fees. If you need cash in a hurry, you can’t sell a bedroom. Stocks can be sold in seconds for near-zero cost. That liquidity difference matters if your circumstances change — job loss, health issue, or a better opportunity elsewhere. A property that takes six months to sell at a 5% discount has already cost you more than most stock market downturns.
Underestimating the entry barrier
Property typically requires a 25% deposit — £30,000 to £50,000 or more — plus stamp duty and legal fees. Stocks can be started with small amounts via zero-commission apps. The opportunity cost of saving that deposit for years while the market moves is real. Someone who invested £10,000 in a global equity tracker five years ago may have outperformed someone who spent five years saving a £40,000 deposit for a flat that’s barely moved in value.
How to Compare Property and Stocks Properly
Run the net return, not the headline
Start with the gross return, then subtract every cost that applies to your situation. For property: stamp duty, legal fees, survey, mortgage arrangement, agent fees (on sale), Section 24 restriction, CGT, and void periods. For stocks: platform fees, dealing commissions, and any tax if held outside an ISA. The net figure is what you actually keep. Most people stop at the gross number and make a decision on incomplete information.
Factor in the leverage effect
A 25% deposit on a buy-to-let means a 10% rise in property value produces a 40% return on your cash — before costs. That’s powerful. But leverage amplifies losses too. A 10% drop in property value can wipe out nearly half your deposit. Stocks bought without margin have no such risk. The leverage argument only works if prices go up, and it magnifies the damage if they don’t.
Consider the tax wrapper first
Shares held in an ISA or pension are tax-free on income and gains. There is no equivalent wrapper for property. That means every pound of rental income and every pound of capital gain on property is potentially taxable. For a higher-rate taxpayer, the difference between a 7% gross return on stocks inside an ISA and an 8% gross return on property after tax can easily favour the stocks. The wrapper is not a minor detail — it’s often the deciding factor.
Look at the timeline
Property is a long-term asset. Transaction costs are high, so you need to hold for at least five to ten years to spread those costs across enough appreciation. Stocks can be held for any period, but short-term trading introduces timing risk and tax complications. If you need the money in three years, stocks are probably safer. If you’re investing for twenty years and want a tangible asset with rental income, property may suit better.
For those considering property investment, understanding the legal side of transactions is crucial. A Real Estate Lawyer can help you review contracts and navigate the purchase process.

Property vs Stocks: Which One Makes More Sense Right Now?
The answer depends on your cash, your tax situation, and your timeline. For someone with a full ISA allowance and a long investment horizon, stocks inside a tax wrapper are hard to beat on net return and simplicity. For someone with a large deposit, a tolerance for illiquidity, and a desire for rental income and leverage, property can still work — but the margin for error is thinner than it used to be. The 2027 tax changes will make property less attractive for higher-rate taxpayers, while ISAs and pensions remain untouched.
