Apparently a business of a close relative of the Ackermans or his parents/grandparents themselves had failed, and they had moved into the mountains. If Mr. Ackerman lived all his life in the mountains, chances are, he would've never really had any chances to awaken that power -- nobody was really around. Eren was Mikasa's only friend, if I can remember correctly.
