I retired in 2019, and moved to be near my grandson in a HCOL area. Luckily, I sold my home at triple what I paid for it. Otherwise, I could not have afforded to live near my grandson.
My federal annuity and SS provide more than enough to live on while my TSP continues to grow. I raised my child to be educated and self-sufficient, which she is, so I don't need to support her.
The only thing I would do differently would be to stay in shape, so I could travel. I'm working on that now.
