Frequently asked
When does buying beat renting financially?
The rule of thumb: if you'll stay for 5+ years, buy (transaction costs spread over more years). If you can't raise a 10% deposit, renting is forced. The Economist's UK rent-vs-buy model (2026) shows renting is still more expensive in monthly terms across most UK regions, but the equity build-up in buying makes it better long-term.
How much deposit do I need to buy in the UK?
Minimum 5% (with Mortgage Guarantee Scheme), though 10% is better for lower rates. On the average UK house price (~£285,000 in 2026), a 10% deposit is £28,500. In London (average ~£530,000), a 10% deposit is £53,000.
