The Lifetime ISA: £32,000 Free From the Government
The Lifetime ISA remains the single best tool for first-time buyers under 40. Save up to £4,000 per year and the government adds a 25% bonus — that's £1,000 free money annually, up to £32,000 over the account's lifetime.
The catch: the property must cost £450,000 or less, and you must have held the LISA for at least 12 months before using it. Withdraw for any other purpose (except retirement at 60) and you'll face a 25% withdrawal penalty — which actually means you lose 6.25% of your own money, not just the bonus.
Who it suits: Anyone under 40 buying a property under £450,000. Start one now even if you're not buying for 3-5 years — the clock starts ticking on the 12-month rule, and the annual £1,000 bonus compounds. A couple both saving £4,000/year for 4 years accumulates £40,000 in contributions plus £10,000 in government bonuses.
Who should avoid it: Buyers targeting properties above £450,000 (much of London and the South East). The penalty for withdrawal makes it actively harmful if you end up exceeding the limit.
