Fluke is a problem in this area, my sheep have it (brought it with them...), but no worms. I treat twice annually, but not sure if goats would not be worse with it.
Also if you are planning to establish a diary herd (goats) you will need quite a good sized barn for all the damp days/snow we are getting. If there isn't one, then it may be difficult to get PP. There is on dairy nearby that manufacture now (apparently) goats cheese too, but buy the goats milk in from England....
Have fun looking, the Borders are nice and both Edinburgh and Glasgow are fairly easily reached, as is Newcastle.
