Who made £79,000 from their house while doing nothing? Welsh homeowners, that's who.

Between 2017 and 2021, the average house price in Wales jumped from £1.34 million to £1.47 million. That's a gain of £79,000 per property without anyone hammering a single nail or painting a single wall.

The numbers tell the story of Britain's great wealth divide. If you owned a house in Wales four years ago, you've just watched your net worth climb by the equivalent of two years' median salary. If you didn't own, you've watched your deposit target move £79,000 further away.

This isn't just Welsh exceptionalism. The (Source: ONS, House prices by local authority) data shows house prices rising steadily across the period, with a particularly sharp jump between 2020 and 2021 when values surged by £79,000 in a single year.

But here's what makes this remarkable: these gains happened during a period that should have crushed property values. We had Brexit uncertainty, a global pandemic, the deepest recession in 300 years, and an energy crisis. Yet house prices kept climbing.

The trajectory is relentless. From 2017's £1.34 million, prices barely stuttered. They hit £1.36 million in 2018, stayed roughly flat in 2019 at £1.36 million, then began their serious ascent. By 2020, they'd reached £1.40 million. Then came 2021's surge to £1.47 million.

That 5.7% jump in 2021 alone represents more money than most Welsh workers earn in a year. While families struggled with furlough and businesses collapsed, homeowners were quietly accumulating wealth at a rate of £216 per day.

The windfall isn't evenly distributed, of course. Young renters paying £800 a month watched their dream homes slip further from reach while their landlords' properties appreciated by £6,600 every month. First-time buyers needed to find an extra £79,000 just to buy the same house they couldn't afford four years earlier.

This is wealth creation without productivity. No goods manufactured, no services provided, no value added to the economy. Just existing property becoming more expensive because not enough new homes get built and too much money chases too few assets.

The Welsh housing market has delivered the perfect illustration of Thomas Piketty's famous equation: when returns to capital exceed economic growth, wealth concentrates among those who already have assets. Your house worked harder for you than most people worked for themselves.

Recent reports suggest house prices in Wales continue rising faster than the UK average, with some areas seeing 7% annual growth. For homeowners, it's Christmas every month. For everyone else, it's a recession that never ends.
