Yes! You can use your LISA to buy a home with another person, regardless of whether or not they’re also a first-time buyer.
As long as you and the property meet the criteria for a qualifying house purchase, you should be able to use your funds towards your first home. LISA eligibility is assessed individually, so anyone else’s ownership status doesn't affect your ability to use your LISA for your first home purchase.
You can also use the LISA to buy with another LISA holder, or someone who holds a Help to Buy ISA. Please note, however, that the £450,000 price limit on the home you buy does not increase if two or more LISAs are used for the same property purchase.
Please note we’re unable to confirm the property's eligibility based on your individual circumstances. If you’re unsure if your house purchase qualifies for a penalty-free LISA withdrawal, we’d recommend speaking with an appropriately qualified conveyancer.
