@Nadir M.Two additional thoughts:1) A central boiler is a cost trap for owners.

The seller/landlord retains full value on the lease payments though if the option agreement is never exercised.

It's not in my current lease, but I will have several units open over the next month, so it's still an addition to my lease that I might want to add.
