Congratulatons!
Since your retirement came up unexpectedly early, now might be a good time to review your investments and see how they will work in retirement. I posted this quote from William Bernstein in another thread:
William Bernstein, in talking about retirement wrote the following:
"Waring and Siegel’s conclusions apply just as well, however, to the individual retiree, who, according to the authors, should have two buckets of assets: a “liability matching portfolio” (LMP) that is structured to provide an adequate lifetime income and a “risk portfolio” (RP) of funds in excess of the LMP that serves for luxuries and bequests."[ 12]

With a rental property and your wife's income, you do seem very well situated.
