I've also heard about that $93,000 figure, but I have no idea where it came from, and I also seriously doubt it!
There are a good many folks here who live reasonably "comfortably" on their Social Security alone. There are also many who live on more "comfortable" retirement incomes combining Social Security with some other pension income (personal 401k, military retirement, corporate retirement, etc.).
I personally manage very comfortably with Social Security, military retirement and the income from my late wife's trusts. More than many, I guess, but considerably less than the $93,000 figure.
Surely, you do need to do some basic math to see whether you can retire here - or anywhere. But, know that The Villages should match 99.9% of the items on your "wish list."
Welcome to TOTV and to TV; this is where it's all happenin'!
