Quoted from pinzrfun:Being mortgage free is not the goal. It's all how you look at things.
I was going to say that as well since our mortgages are paid by others, on top of which we make profit and can sell the paid-off-by-others real estate when we retire to have ample play money if need be. Property manager handles it all, so we don't do a darned thing but spend the cash. Mortgage free is not the way to go currently given the low interest rates in this country, but the last time I dared suggest that I got ragged on by the generally older audience here at pinside, so this time I'll let you take the slings and arrows for it and I'll leave it at that
As for the pins, honestly just sell all the common ones. I find it's good sometimes to just purge, it helps you to see what you really need. If you miss some no biggie, since they are common ones you can eventually re-buy them. But I suspect you'll find that you actually miss far less of them that you'd have thought!
