December '12 - $161,110
December '13 - $225,147 ($64,037, 40%)
December '14 - $261,912 ($36,765, 16%)
December '15 - $272,926 ($11,014, 4%, ouch)
December '16 - $371,957 ($99,031, 36%)
December '17 - $528,534 ($156,577, 42%)
December '12 doesn't have home equity and we sold the house and rented in '13, so that's where that jump came from. For '16 and '17 I've included very conservative estimates of home equity.
