I wouldn't even *think* of owning the tank with the numbers
being that the tank "could" pay for itself in just a couple
of fills.

In my other house (currently rented and under contract), the 250gal
propane tank is rented. I think they wanted something like $500
($1500 if buried) for it, IIRC. The rental is $45/year. There was no
way I'd buy it.

That it might spontaneously ignite is not a worry.

Right.

More to the point of home repair, the regulators (of which I have
3 low pressure and 1 high pressure) seem to need replacing, by
law? about every 12 years (if you believe Amerigas) or every
15 to 25 years (if you believe the propane association).

Amerigas: 12 years:

Propane Association: 15 to 25 years:

The cost to replace 1 regulator is $300 if Amerigas does it,
and about $73.22 if we do it ourselves.

....and if I change my mind, I want to get rid of it without issue.
When we sold the house there was a question about the tank. Don't
want it (no fireplace and no gas stove), fine. Take it out.
