I know the feeling, I have been topping up my LISA since they started and I now have a considerable sum in there that will cost me a big chunk to take out unless I can find a property for 450k which isn't going to happen.We nearly gave up with my other half. We budgeted 500k for a first time house and have deposit etc ready, we’ve been maxing out our life time isa for a few years now and when we started the budget/max house price was comfortably in our range.. silly us to forget about that limit and learn that it is now set to 450k. If we wanted to take out our savings we’d lose the “benefit” which I accept but also would get fined on topso we have to find a property for under 450k which seems difficult where we live and everything goes massively over asking. E.g of a 3 bed bungalow, last year sold for 325k, now back on the market for £450k. Literally less than a year since it was sold.
so the government penalising us for taking out our savings is a pig. On top of everything else. As an example:
put in £4k a year
Government end of tax year adds £1k
Have £5k in total
decide to buy a property under the limit? Fine you get the £5k
decide to go over and have to take the money out? We’ll deduct the £1k bonus you got to help you to buy and we’ll also penalise you £250 for the privilege.
so your £4k ends up being £3750.
just a kick in the balls. And when you have a good chunk in there you end up losing thousands. Stupid system.
I have other savings and count my blessings the LISA was capped at 4k or I would be in real trouble. I can fortunately afford to purchase a house without the LISA cash and will instead see that on the other side (when I retire

When I first started looking at properties, 450k seemed even too much but career progression for us has allowed to us stretch ourselves further. Sadly the career progression came too late in the sense I couldn't take advantage of the "covid" relief and take my money out penalty fee. Id be more than happy to return the 'bonus' to the gov but taking the 25% hit is a very bitter pill to swallow.
