Personally, I stay away from those that force an annuitization in ten years. Allianz has some nice ten year walk away annuities.
This way you can perhaps get more income purchasing an immediate annuity down the road, but not be locked in if their financial situation has changed.
Which companies force annuitization in 10 years or at any point for that matter?
Funny you mention ALLianz as one with walk away products, they were the KINGS of annuitization even at death. It only took law suit after law suit to get them where they are today.
