Can I use the Lifetime ISA to buy a home with someone else?
Yes! You can use your Lifetime ISA to buy a home with another person regardless of whether or not they’re also a first time buyer.
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.
