Advice on buying a house in Mauritius from the UK?

I am strongly considering buying a house in Mauritius. I am a UK citizen but engaged to a Mauritian who is living in Mauritius.

Originally we talked about her moving to the UK but due to family circumstances I have agreed to explore moving to Mauritius. I have a well paying job in the UK and she is working in Mauritius.

I have £100-120k deposit I was planning on using for a house in the UK, but if I decide to instead buy a house in Mauritius - do you have any advice?

How far could that money go? Would it be easier for me to gift the money to my fiancé to buy the house, etc? How do mortgages/loans for houses work in Mauritius?

Grateful for any advice!
