Those Annuities don't sound great, 6.4% yield if just you on the policy and only 5.8% if you add your wife to inherit the policy if you die someday (sorry but high likelihood, nothing lasts forever)
consider as recc above, find a few good syndicators with several upcoming deals you can identify within 45 days of the sale of your condos (sell all 15 as a package to some investor), then invest as a TIC, tenant in common, with one syndication deal, there won't be any fees, then make sure it's a longer term 10 year at least investment, then keep rolling until death. Then kids get the step-up. I recc NNN-multi-tenant large shopping centers that due cost segregation analysis at purchase to get maximum depreciation up front. CRE retail has good fundamental outlook next 5-10 years due to lack of supply. This segment has been big picture stable last 100 years. Also, multifamily (now down 30%) but wait 1-2 more years for massive new supply to be absorbed. I just invested in 3 different Data centers, they are too high risk for most people to consider, especially in retirement. Industrial is great too, long term, but a little overpriced still for now.
or sell, pay the taxes, invest in VOO, get 8-10% next 30 years, or invest in REITs, get 10-12% next 30 years
or buy MUNIs, i'm getting 5% tax free, which is an effective yield of 7.94% for part of my emergency fund
If you die 1 day , 1 yr, 1 decade after you sign an Annuity, they keep all your money, your wife/kids get nothing, unless you add them, but then the returns do go way down and they were low to begin with, Remember the Annuity company is investing in VOO and last 20 years got 13% a year, (long term 8.4% since 1801) they pay you 6 and keep the rest, good luck brother :)
