Airbnb would make recognizing that it's your property nontrivial. They don't show a specific address until a reservation is accepted; the point on the map is randomized and can be a few blocks away; photos are supplied by the host and may not match photos the landlord has (if the place is sufficiently well decorated and not distinctive, it may be hard for even a human to determine it's the same place).
If however you licensed some good facial recognition technology, perhaps you could compare the face in the Airbnb host's avatar with that on the ID each of your tenants supplied when applying for an apartment. It would be far from bulletproof, but could get you somewhere. In a less-densely populated place maybe you could even get away with "notify us if someone named Bob offers a new room within 0.5 miles of 622 Cedar St", perhaps hiring low-paid humans to sanity-check the results before passing the notification on to the landlord.
