First choose two locations.

Then list the pros for each and the cons for each.
Valleys are known for fertile soil. Mountains you have privacy. House near the steep rocks has the same advantage as moutains, however, a sandy area doesn't allow you to grow your own food, so I wouldn't build a house there. Overall, I'd end up choosing food security of the valley, over the security of the other two.
