Sounds like fun! We've been living in a manufactured house for about 15 years now. Cheapest house in the neighborhood by about a factor of 10! Works fine for us. We don't entertain a lot. We live a ways from family & friends, so we meet at restaurants in between. We NEVER buy new cars. We usually keep them running for a decade or more. We have maxed out 401Ks and IRAs, saved about 15% of my income, and rented out houses instead of selling them when we need to move.

When I got Medicare, my last job terminated me and I was quite happy. I was just working because I figured they needed me. They probably made double my salary on my work, and it would have been even better with Medicare instead of group coverage. Oh well, their loss and my gain.

I have made a very comfortable retirement for us. I don't think we will ever need to touch the principal, so we could afford to be retired forever, in the off chance they make fantastic progress with medical care!
