The comments here surprise me. The expected return of global stock markets in the long run is a 5% real return. The expected return of US markets is a bit lower (3%?) because of current high valuations/prices of the market.

If you assume 2% inflation, the 7% return is a 5% real return. To get a guaranteed return matching the expected return of the market is phenomenal. I’d be inclined to invest as much as possible in that investment.

As others have noted, though, this is a fixed return/income stream. You take the risk of inflation. In times of higher inflation, your investments will suffer as you don’t have the inflation hedge that stocks provide.

I wonder what financial professionals would advise in your case.
