How long do I have to live somewhere before buying beats renting?

The break-even point is typically 5–7 years in most UK and EU cities. Below 5 years, transaction costs (stamp duty, legal fees, agent fees on sale) usually outweigh the equity built up. Above 7 years, paying down a mortgage normally beats renting. This calculator finds your specific break-even point.

What is the opportunity cost of a deposit?

Money tied up in a property deposit could have been invested elsewhere. If a £50,000 deposit could earn 5% in a global equity index, that's £2,500/year of foregone returns — a real cost of buying. The calculator includes this so you compare like for like.

Should I include rent increases in the comparison?

Yes. UK rents have risen 3–6% per year on average over the last decade. The calculator applies your chosen annual rent rise to project realistic future rental costs.

What about house price growth?

House price growth is the strongest argument for buying, but it's uncertain. The UK average is ~5% per year over 30 years but with significant variation by region and year. The calculator lets you set your own growth assumption — 0% to 6% is reasonable for stress-testing.

Does the calculator include stamp duty and fees?

Yes — input upfront costs (stamp duty, legal, survey, agent commission) and they're applied on day one for the buy scenario and again on sale. Selling costs typically add 2–3% to total cost of ownership.

Beyond the Numbers: When Renting Wins

Buying isn't always financially superior. Renting is often the better choice if:

You plan to move within 3–5 years (transaction costs eat any gains)
Your career is mobile or international
You lack a stable emergency fund alongside the deposit
The property requires major maintenance you can't fund
Renting frees deposit money for higher-return investments (e.g., starting a business)

When Buying Wins

You'll live there 7+ years
You have a sizeable deposit and strong income stability
Local rents are high relative to house prices (rent/price ratio > 5%)
You value the security and freedom to modify your home
You see homeownership as forced saving / inflation hedge
