When I was younger, I had visions of retiring in my 50s. I used a dual track. I had been funding 401K for years and looked at all the options for retiring early. I could not find any way to reasonably use tax deferred funds for early retirement. I ended up saving outside the IRA/401K containers through austerity. Because I'm older than my wife, we eventually decided to retire together when she became eligible at age 56. I ended up using those additional savings to fund a slow transition to a retirement home. By buying a few acres of retirement land and building a barn with a tiny living space out of that savings, we now have a get-away place. We will be able to sell our suburb home and move into that tiny living space while we build our retirement home next to the barn. This avoids the high cost of a bridge loan (construction loan) which is especially helpful these days with supply chain delays. For me, things changed significantly at work since my 50s. I'm now outside the critical path and am functioning more as a grey beard. With COVID considerably easing the commuting pain, and increased flexibility with my work hours, I'm now enjoying work more than ever, so I'm in no rush.
Keep in mind there are both advantages and disadvantages to early retirement. On the plus side, it give you a lot of time to do the things you enjoy while you are in the best physical condition. On the other hand, unless you are quite fortunate, you probably have less discretionary funds to do the things you enjoy. Also, for every year you retire early, it is one more year you are eating out of your nest egg and one less year you are building it. It is hard to find the right balance.
Best of luck,
Jack
