Agree on the ROR vs LTV. I also would suggest, however, that “new” money going to Old Mutual will earn nothing near 8.25%. Those 5, 10 and 25 year average return numbers are next to meaningless unless you have had your money in for the stated term or longer.
In order to get the tax break you have to pay in monthly or if you have a lump sum, over a five year period. They put the money in a side fund and move it across each year if you have a lump sum.
I gave you the average for the last 25 years. If you take the money starting the 11th year you will have the 8.27 minus about 1% fees. If you start a fund for a grandchild and they use it for their retirement 65 years later, they'll do very nicely thank you.
A person refinancing will come out ahead of their interest payment if they put some in an IUL and they'll have a death benefit.
