New Move/Care for Elderly Father. Cost and Living Questions

Hello all,

I am contemplating the move with my Father(74) and I(42) to Sri Lanka. I have read much but still have questions.

What would/should it cost to have someone to live in or on premises to watch out for my Father and prepare at least one meal a day? He is in early dementia - but not inactive. I just want someone as a watchful eye/house assistance?

I am hopeful we can find a vintage/victorian/colonial type home in the outer country. This way I have personal space and so does my Father. From those who know the country best.. is this practical? I like cities well enough but my Father is not a city person.

I currently care for him in the Caribbean in a rural beach community...This will be different but still island, tropical, rural life...

thanks
