Budget for single person moving to cayman?

Hey everyone

I’m a professional considering a move to cayman early next year.

I know the cost of living is very high and rentals on the island are not cheap…

Based on my research I think I should be able to get a decent 1 bedroom place for around 3.5k usd per month.

Would be very grateful if anyone could give me some guidance on how much I should also budget for cost of living (excluding rental) each month.

Many thanks
