Ray - My 2-cents as a lender: Scott really nailed it with his advice above (Brent, too!).

Michael kinda nailed it.

I do require my tenants to call me before they dig or put a nail in a wall or installing anything.If you do have more than 3months on the lease, Then I would suggest that you do send them a violation notice, And start a discussion with the business owner who signed the lease.

If it is a tract home chances that copper plumbing are contractor quality and it can be pierced by a gravel, rock or a nail causing water leakage.

So effectively it limits what you can borrow in future.As far as the estate planning, you just need to nail down who owns what percentage of the asset. 

@Jerry W.hit the nail on the head.

Once you've nailed down a turnkey provider, though, your time and effort requirements going forward should be minimal.

I would need at least cross-streets in order to nail the value better for you.

@Dave Skowhit the nail on the head.
