I'm not sure that I can adequately answer that question.
We live on base and have for two and a half years. I wasn't aware of the policy. I do know about the new PLD situation that has just switched. I can only speak from my experience. Should my family live off base, due to my husband's rank, we would only see about $150 a month.
Unfortunately, we live in the Borden area, so a three-bed, two-bathroom home would be close to $3,800, which would be significantly more than what we are paying on base. It is more of a financial inequity situation.
I'm not sure if that answers your question.
