Interesting data: buy-to-let in the UK outperformed the S&P 500 over 30 years — £1 invested in 1996 became £22.30 when you factor in rent and price appreciation. But let's be clear about what drove that: leverage and a multi-decade housing bull market.

Mortgages magnify everything. Rising prices? Landlords win big. Flat or falling prices? That same leverage works against you fast. And housing doesn't always go up — Germany, France, Spain, Italy, Japan all had decades where real home prices went sideways or down.

The real question isn't what happened over the past 30 years. It's what UK house prices will do over the NEXT 30. Nobody knows. Leverage cuts both ways, and mean reversion is real. As a growth investor who's managed money through multiple cycles, I've seen how quickly sentiment shifts when fundamentals weaken.

I still favor liquid, diversified equity exposure in quality businesses over illiquid, concentrated real estate bets — especially when valuations are stretched and interest rates aren't at zero anymore. Stay disciplined.
