Buying isn't always better

Short holding periods, flat or falling house prices, and high mortgage rates all swing the maths toward renting. The break-even point is often longer than people assume.

The deposit matters most

The single biggest variable is what the renter does with the deposit. If it sits in a current account earning nothing, buying almost always wins. Invested sensibly, it's a real contest.

Things this doesn't price

Flexibility to move, security of tenure, the freedom to renovate, the hassle of landlords. These are real — just not easily put in pounds.

Buy vs rent FAQs

It compares two parallel futures over your chosen holding period. In the 'buy' future, you pay the deposit, stamp duty and buying fees upfront, then a monthly mortgage plus maintenance and insurance. In the 'rent' future, you keep the deposit and frictional costs invested at your chosen return rate, and pay rent each month. We grow house prices and rent by their respective annual rates and compare net positions at the end.
