For a first home costing £450,000 or less, or for money you are content to leave until 60, the 25% bonus is difficult to beat. For anything else the 25% withdrawal charge leaves you with less than you paid in.
Any other withdrawal carries a charge of 25% of the amount taken. On £1,250 made up of £1,000 saved and a £250 bonus, the charge is £312.50 and you receive £937.50.
The £450,000 cap has not moved since the Lifetime ISA was introduced.
The cap has not moved since the Lifetime ISA was introduced. If the property you buy costs more, the withdrawal is not charge-free, so you would lose the bonus and more besides. It is the main risk for buyers in expensive areas.
Shared ownership purchases can qualify. The rules are specific, and your conveyancer handles the withdrawal, so check the position early.
For most employed people, no, at least not before taking any employer pension match on offer. A pension contribution attracts tax relief at your marginal rate and an employer may add to it, where a Lifetime ISA adds a flat 25%.
The money stays invested and becomes available at 60 without charge. The cost is that it was locked up in the meantime.
It depends on what the money is for and when you will need it. Those are the two questions worth settling before you open one.
