There are, but any agent worth anything is probably trying to upgrade that client to a better product (for their situation) the day it comes out of surrender. You'd need exceptional timing to do any real volume.What got me thinking on this line was a recent prospect who purchased an annuity 12 years ago, still hasn't turned on income and we showed an immediate increase in both accumulation and income benefit base value on day 1 (with few % surrender remaining) plus about 18% lifetime income increase. Figured there would be others in similar situations as her but I see that it is a very particular subset of purchasers who would meet the necessary criteria (i.e. very long deferral period and haven't yet turned on income).
