Lifetime ISA - "First home" question

I could utilise my Lifetime ISA to assist in purchasing my initial home. However, as I inherited a small, centuries-old (from the 17th century) property with limited habitability through shared ownership in a rural area in France—a country where I've never been a resident despite holding citizenship—I am uncertain if this would disqualify me from using my Lifetime ISA for acquiring my first home in the UK. I appreciate any assistance you can offer.

Hi

If you inherit a residential property, you are no longer classed as a first-time buyer, even if you never live in the property or only inherit a tiny share.  
In order to qualify as a first-time buyer you cannot own, or have owned, a dwelling, regardless of how it came into your ownership.  

Thank you

Hi, as a vicar in tied accommodation. Can I still purchase a house through lifetime isa? I will only be able to live in it when I’m not working and when I retire or if I lose my job. I am a first time buyer and don’t own a property. This house I buy through the Lifetime ISA would be my principal private residence. So in essence could I buy my principal private residence through the life time isa but still live in my tied accommodation?

Hi Topherstewart11 Stewart,
You do not own the tied accommodation, so if you purchased a property and you are a first time buyer, you should still be able to purchase with your life time ISA.
The age limits (18 -40) only apply when opening a life time ISA.
Please have a look at the guidance here:
Lifetime ISA
Your ISA provider should also be able to provide you with more information.
Thank you.
