AnnuityWhat about an annuity?

Obviously, if you are getting a retirement payout or have regular annuity payments setup, those would be used as well. 

IMO it's a niche product like an annuity. 

This is a great opportunity to listen to your CPA who knows about your taxes, finances, different type of IRAs. annuities, life insurance.

As much as I hate annuities, you might speak with an annuity agent about the employer awarding a bonus in the form of a single premium deferred annuity invested in index funds and that you do not have the right to access until a date certain and then a full payout over time.

That's why you see so many annuities out there for people who don't need them. 

I focus primarily on the Medicare (65+) market, life/health/annuities.

If you want to earn 3% return you could just invest in a conservative annuity or something!

Do I save up enough money to buy an annuity to get that guaranteed income?

You should definitely look into some sort of annuities stream your funds can offer you and roll a portion of that into real estate investments.
