My answer changed after reading some of these... I forgot about a few
As a child-- moved once
College age-- 3 residence halls & 2 apartments. Then moved in with a military family in Italy as their nanny. Then moved in with my boyfriend/now husband (shh! don't tell my dad) when my nanny job was over but he was still there so I wanted to be, too
Then moved to my mom's (new) house when his assignment in Italy was over=8
Married life (14 years)--We've been stationed in Japan, England, Illinois (not so exciting after Japan & England!) and my kids & I lived in our "forever home" (an impulse-buy in South Carolina) while my husband was in school in D.C. for a year. Our current assignment and most recent move is to Turkmenistan. If the new housing is complete here soon enough, we'll probably do a local move. My husband will retire out of here and we'll move back to South Carolina. He is so done moving (but I wish he'd change his mind and get another assignment or two!) =5 (+1 or 2 more by the end of next year)
So 13 homes as an "adult", 2 as a child.
