Hi EMH2024,
We can not comment on the qualifying conditions under the LISA, as all we deal with is the taxation of any investments.
If the investment is a LISA, then there would be no tax consequences for any interest etc.
We also can not give you any financial advice.
All we can do is point you to the guidance here:
Lifetime ISA withdrawals for a first time residential purchase
And suggest you conract your Lifetime ISA Provider.
Thank you.
