Hi Peggy
We live about 8 miles from Coylton in another village but i know Coylton quite well. If you look on net for south-ayrshire council that is your local authority for that area you may get an idea of council tax etc. you may also find houses for rent. And if you check out the asda website that will give you an idea of groceries and electrical goods.
I think there are quite a few buses run to coylton so that wont be a problem for you.
Good luck hope all goes well.
