Your first mistake is having those funds in a 401K. The absolute only reason to have a qualified 401K is to take advantage of any employer matching funds. When you withdraw those funds you are going to be hit with income taxes on what you deferred and on the earnings. You could create a charitable remainder trust, either a CRAT or a CRUT. But that is going to limit your yearly distributions
A ROTH is a much better option, pay the taxes now and the money is what I call NONEYOU money. What you take out during retirement is none of the government's business. Of course, there are contribution limits with the ROTH. But investing non-qualified money means paying capital gains taxes instead of income taxes on any distributions.
Your second mistake, not wanting to make moves. Harvesting losses within nonqualified investments is an integral part of proper portfolio management. I know the mantra, invest for the long-term is always spouted, but just like in retail, profit is in turnover, not carryover. Warren Buffet may be the most famous value and long-term investor, yet he still utilizes loss harvesting.
And speaking of Buffet, what the hell is a retirement home? Selling the family home, with the revenue being tax-free, and moving to a two-bedroom condo in the Villages might be a better move than biting off a new house, and certainly not taking out a mortgage for it.
But perhaps your biggest mistake, flippin Florida. Damn skippy insurance is through the roof, because Florida is a shithole. Hell, they are giving South Carolina a run for their money now. Western North Carolina is a much better option, and even the Piedmont and Coastal areas have a lower cost of living, and in most cases, better healthcare and safer. Hell, I don't even bother locking my door when I leave.
The rest of your rant is just political posturing. Sure, the market did good under Trump. S & P up 67%. And yes, that was better than Biden. But Obama, up 182%. Clinton, up 210%. Eight years of Bush Jr. , down 40%. Even his Daddy, in four years, posted a gain of 51%. Reagan, up 118%. The day Obama was inaugurated I left for work, driving a mile down my private drive, a hawk following me overhead. That day I took in hundreds of thousands of dollars in investments and by the time he left office, well my ass was a hero.
