Sell the house and downshifting into an apartment if you are willing would be a huge boon.
You're getting older, you won't have to worry about yardwork or maintenance etc.
Run the rent versus buy numbers (there are calculators for this online, NYT springs to mind). See if it makes sense... also keep in mind that you're 60, I presume if you have kids they're out of the house by this point, and you're not taking care of your parents in your home. (All big assumptions, correct me if I'm wrong).
Point I'm trying to make is, you probably don't NEED that much space, so renting a ~2bd apartment would be perfect and would instantly solve your cash flow problems in most locations.
You'd be debt free, with over 1M in retirement accounts (able to instantly be tapped due to your age) plus the equity in your home, and Social Security / Medicare starting soon.
Unless your spending is WAY out of proportion, which you didn't comment on, you won the game, you've worked hard, relax and enjoy yourself.
