Buy-to-let returns hit 2,130% over 30 years, Hamptons research claims

Research by Hamptons suggests landlords who bought at the launch of the buy-to-let mortgage in late 1996 have seen total returns rivalling the world's best asset classes. Every £1 invested in the average British buy-to-let property generated £22.30 by 2026, a total return of 2,130%, based on ONS house price and rental growth figures.

How buy-to-let compares with other assets

The figure narrowly outperformed the S&P 500, which returned £22.05 per £1 invested over the same period (2,105%) with dividends reinvested. Hamptons claims both property and US shares delivered nearly three times the returns of the FTSE 100, at £8.96 per £1 (796%), and gold, at £7.36 per £1 (636%).

Almost two-thirds of buy-to-let returns, 62%, came from rent paid by tenants, with the remaining 38% from rising property prices. The picture has reversed more recently: cumulative returns over the past five years stand at 75% for the S&P 500 and 73% for the FTSE 100, against 41% for residential buy-to-let.

The changing landlord profile

The research also reveals how landlords have changed over a generation. The average landlord in 1996 was 37 years old, buying at an average price of £54,900 with a 29% deposit and a mortgage rate of 7.76%. Despite the high cost of borrowing, 88% opted for a repayment buy-to-let mortgage.

Today, the average buy-to-let purchaser is 51 years old and paying £360,000, more than six times the 1996 figure. Deposits are little changed at 27%, while rates average 4.52%. Seven out of 10 mortgage buy-to-let purchases today are interest-only, and fixed rates account for 99% of buy-to-let lending, up from 26% in 1996.

What it means for agents

Aneisha Beveridge, Head of Research at Hamptons, said that when the buy-to-let mortgage launched in 1996, few predicted it would become one of the largest wealth-creation engines of modern British history, opening the door to a new breed of middle-class investor. She noted that while these investors were in their 30s in the 1990s, many remain landlords in their 60s today.

The sector has become more professionalised, dominated by older, experienced investors, with younger landlords dabbling in buy-to-let alongside a day job increasingly rare. Today's largest portfolios often began in the late 1990s and have accrued substantial equity through successive house price booms, often reinvested into further purchases. For a growing number of landlords, properties are now part of a wider family business likely to be passed down to the next generation rather than sold off in the face of rising tax rates.

For letting agents and inventory clerks, this long-held, equity-rich and increasingly institutional profile of landlords is a reminder that many clients are now seasoned portfolio owners, often with succession planning in mind, rather than first-time investors.
