The SIOR website lists 844 South Walbaum Road as "corporate headquarters," and both McCoy and Lloyd use it as their address for corporate purposes. Agents and officers often use work addresses, rather than home addresses (although I have no experience in Oklahoma).
The driveway certainly looks more like a work driveway than a home driveway, especially for a mobile home (as you say). Further, your Trulia.com link does not show a number of bedrooms, which is consistent with an office.
So remind us why you think that this address is someone's personal residence?
I am an amateur at this, and it would be unwise to rely on my opinions without your own independent confirmation in consultation with an investment professional.
