How much residents of each state owe on their mortgages is an interesting statistic. For the most part, residents of the states with the highest average mortgage debt are not in trouble. While the average home price in these states dropped in value during the recession, the foreclosure rates in these states are among the lowest in the country. The reason: residents of these states can generally afford to lose and owe more money than their counterparts in other states. 24/7 Wall St. examined a recent report by Credit Karma to find the 10 states with the highest average mortgage debt.
