I have a prospect with a four year old UL. It's guaranteed to last until she's 81. I had te carrier run me an in force. It's projected under current assumptions (4.25%) to last until 95. Projected at 4% to last to 90. It's $20K in coverage for $40 per month. She qualifies for an FE WL of 15k for 52 per month. Should I replace it?
