Renting vs buying in the UK, key things to consider

Financial calculations only tell half the story. While buying generally wins over long periods due to capital appreciation and fixed mortgage terms, renting offers significant flexibility. First-time buyers should particularly note that upfront costs (like Stamp Duty and legal fees) take years to recover via equity.

Make sure you consider the "buyer-only" costs that renters avoid. Homeowners are liable for all maintenance, buildings insurance, and in many properties, service charges and ground rent.

The winner is whoever has the highest net wealth (Equity + Cash) when selling.
