Your House Made You Feel Rich. It Didn't Make You Wealthy.

My house went up £50,000 last year. Unfortunately, so did every house I'd want to move to.

The French have a phrase for it: the English disease. Our national obsession with bricks and mortar. Dinner party conversations that inevitably drift toward house prices. The quiet smugness of having "got on the ladder." The unshakeable belief that you can't go wrong with property.

Except the data says you can. And for the last decade, you mostly have.

The Golden Age Is Over

Between 1980 and 2016, UK house prices rose 6.7% per year in nominal terms. London did even better at 8.5%. If you bought a house in that era, congratulations — you rode one of the greatest asset booms in British history. But that era is over, and most people haven't noticed.

Rathbones published research in 2025 that should've been front-page news. £100 invested in UK property in 2016 was worth £134 by 2024. The same £100 in a diversified global equity portfolio? £174. And if you had the misfortune of buying in London — the supposed crown jewel of British property — your £100 became £111. That's 1.3% per year. Inflation alone ran at about 2.5%.

Oliver Jones, Rathbones' Head of Asset Allocation, put it bluntly: "The idea that you can't go wrong with bricks and mortar just isn't true."

Over 124 years, the Barclays Equity Gilt Study shows UK equities returned 4.9% per year in real terms. Residential property? About 1.2%. That gap compounds into a chasm over a lifetime. £100 in equities in 1899 would be worth roughly £28,000 in today's money. Property capital gains alone barely kept pace with inflation.

The Costs Nobody Talks About

Here's the thing about property that makes comparison with equities fundamentally dishonest: nobody counts the costs.

You can buy an index fund for free. Zero stamp duty, zero solicitor fees, zero surveys. Selling it takes seconds. You can sell 10% of it if you need cash for a new boiler. Try selling 10% of your kitchen.

A round-trip property transaction — buying then selling — costs roughly 5-8% of the property's value in fees alone. Stamp duty, solicitors, estate agents, surveys, EPCs. On a £300,000 house, that's £15,000-£24,000 gone before you've even argued about the boiler.

Then there's maintenance. The old rule of thumb was 1% of property value per year. Recent data from Checkatrade puts actual average spending at £7,530 per year — closer to 3% of the average property value. That leaky roof, the new windows, the damp that turned out to be more than cosmetic — it all adds up in ways that never appear on a Rightmove listing.

And liquidity? The average sale takes 96 days to complete. One in three sales marked "Sold Subject to Contract" collapses. In a three-property chain, there's a 56% chance at least one link breaks. Try panic-selling your house in a downturn and see how that investment feels.

The Concentration Problem

The ONS Wealth and Assets Survey shows that 40% of UK household wealth sits in property. It's the single largest component — bigger than pensions, bigger than financial assets. In any other context, we'd call this what it is: a catastrophically undiversified portfolio.

If your financial advisor put 40% of your pension into a single illiquid asset in one geographic market, you'd fire them. But when it's a house, we call it getting on the ladder.

The house price-to-earnings ratio tells the story of how we got here. In the 1990s, the average house cost about 4x average earnings. Today it's 7.6x nationally, 9.5x in London. Schroders found the last time houses were this expensive relative to earnings was 1876. And a Bank of England working paper concluded that nearly all of that price rise was driven by falling interest rates — a one-off structural shift that can't repeat because rates can't fall much further from here.

Meanwhile, the generation that was supposed to benefit from all this wealth creation? Homeownership among 25-34 year olds collapsed from 59% in 2000 to 39% today. In 1996, 65% of young adults on middle incomes owned a home. Twenty years later: 27%. The property ladder pulled up behind the people who got on it first.

The Psychological Dividend

Here's where I'll push back on my own argument, because I think it matters.

Morgan Housel makes a point in "The Psychology of Money" that I keep coming back to: financial decisions aren't just about returns. They're about sleeping at night. He argues you should aim to be reasonable with money, not purely rational — because you're a human being, not a spreadsheet.

A home you own outright — or close to it — gives you something no index fund can: the knowledge that nobody can take your roof away. That's not a line item on a balance sheet. It's peace of mind, and peace of mind compounds in ways that don't show up in the Barclays Equity Gilt Study. Fewer arguments about money. Less anxiety when markets drop. The freedom to take career risks because your fixed costs are low.

If you can afford to buy a home without stretching yourself into a massive mortgage, that psychological security has genuine value. Housel himself paid off his mortgage early, knowing full well he'd probably earn more investing that money. He did it anyway, because the feeling of owning his home outright was worth more to him than the optimal financial return.

That's a perfectly valid choice. The mistake isn't buying a house. It's confusing the psychological dividend with a financial one — and then using it as an excuse not to invest at all.

So What's the Point?

The Swiss have a homeownership rate of 42%. The Germans, 47%. Their median household wealth is comparable to ours. They don't treat their home as their pension, and oddly enough, they seem to manage.

If I've learned anything from tracking my own finances obsessively — and I mean obsessively — it's that the boring, diversified, low-cost approach beats the exciting, leveraged, concentrated one almost every time. Your house is where you sleep. It might also be where you feel safe, and that's worth something real. But your ISA is where you build wealth. The sooner we stop mixing those up, the better off we'll all be.
