How to valuate shop equipment for retirement sale

[Matt@RFR]

Matt have you considered selling the building and all for a percentage of the profits per year?

We've tossed the idea around, but investing the proceeds from selling the building would net far less than the rental income it will earn, plus renting the building still keeps the building as an asset for down the road. So, whether there's a machine shop or not, the building stays in our name for a couple more decades. I also like that when I die (I'm definitely dying first), my wife can sell it if she wants. We have no need for life insurance.
