I hope so.
MBR just informed me that I'll need to apply for Medicare in November even if I am still working. Which I will be. For a long time.
I did take a look at monthly expenses and even with my current mortgage, I could probably do it for around $6k/month. Less, if I am more frugal. But the issue with that is utilities (we had a ridiculous rate hike late last year), groceries and other things will not hold steady. If I am spending $300 on groceries now, what will that be 5 or 10 years from now?
