Can I buy and sell a house quickly to access the money in a LISA?
I've got £476,000 but the maximum house price is £450,000. What   happens to the £26,000. Does it stay there with ~6% interest (and no bonus of course), and would be available when I retire at around 75 (there would be about £106,000 by then)? Yes, anything you don't withdraw for your house purchase stays in the Lifetime ISA and keeps growing there. Also you do keep the bonus on it, which was paid at the time you subscribed, unless you make a withdrawal before age 60. After age 60 you can withdraw and keep the bonus. Note that you need to be buying with a mortgage to be allowed to use the lifetime ISA money (without penalty). This is mentioned on the gov.uk website as well as in the actual regulations that establish lifetime ISAs (search for "first time residential purchase" and look at clause (6)). That would mean you'd need to withdraw even less than the £450K and artificially borrow the rest. All that said, I suspect the £450K limit would be raised by 2049, given inflation. Can I buy a house and "quickly" sell it again, to simply access the money, The regulations say that on completion of the purchase, you must "occupy the land as their only or main residence" (there are a few exceptions, such as if it's still being built, or if you are at the time posted abroad by the government, but essentially you have to move in as soon as possible). There's no time limit stated in the regulations, so in theory you could move in and then sell quite fast, but personally I'd be nervous about this being seen as not genuinely intending it to be my main residence. In theory you could be prosecuted for fraud if you claimed a valid withdrawal when it wasn't, though given the wording of the regulations it looks like you'd be complying with the letter of the law.
