$280,000 x 3 = $840,000. Therefore, based on OP’s thread starting post, the life insurance payout was in the area of $900,000 if $280,000 was almost one-third of the death benefit amount.
To lower your EFC, just select the death benefit in the form of an immediate annuity. (Please do not be confused by another poster’s reference to deferred annuities as this has nothing whatsoever to do with your situation.)
That should answer your question of “Any suggestions to lower my EFC?” because the lump sum death benefit amount is not relevant if you select the death benefit payout as an immediate annuity (which can be for any number of years including for the remainder of your life).
Any experienced life insurance agent or CFP (certified financial planner) or CPA properly licensed in your state should be able to assist you as this is a very elementary matter–although of great importance to you.
Nevertheless, a full review of your financial situation in light of your needs and goals does call for a comprehensive review by a properly licensed, qualified individual in your state. Typically, one would consider using a CFP or a CPA.
An important issue is whether or not you have already taken the death benefit proceeds in a lump sum and, if so, how long ago was that sum received (as it may be reversible within a certain time period in your state). Again any CFP, CPA, or experienced life insurance agent properly licensed in your state should be able to assist you.
