I'd rather buy cheap and have reputable contractors put in new quality equipment than buy average properties that are functional but I have no idea the maintenance or service life left in these major systems.  

You said non profit, but I'm guessing you can charge membership fees or use fee for the climbing gym or renting equipments etc...

For instance, assuming you have 2 identical properties (hypothetically, but I have seen this quite often in new subdivisions where owners build the same model but some add a basement) one with basement and the other without basement.Property without basement:  3,000 square feet selling for $300K, or $100 per square foot.Property with basement:  identical 3,000 plus 1,000 basement, for a total of 4,000 selling for $450K.  

As a wholesaler, you can state that you have never lived in the property and have no knowledge of defects, materials, mechanical equipment or amenities.

I'm seeing many smaller towers near highways that are no longer holding the equipment.  

(b) If the records of a series are maintained in a manner so that the assets of the series can be reasonably identified by specific listing, category, type, quantity, or computational or allocational formula or procedure, including a percentage or share of any assets, or by any other method in which the identity of the assets can be objectively determined, the records are considered to satisfy the requirements of Section 10A-5A-11.02(b)(1).

For the most part we run credit and ask for taxes to verify identity.

There can be special equipment required by a tenant and equipment leased, the equipment provider may require the building owner to be on the lease or consent being responsible for removal fees.

i am looking for a shop to store my equipment and do routine maintenance in the winter.

The rules for securing information and the disclosure of the reports is getting increased pressure because of all the identity fraud publicity (and reality).
