I didn't dive into great detail but to me it doesn't seem like the contract between tenant and seller is a legally binding one, but I am not sure. 

Without proof and because of the 15 year clean history with the contractor (how well I knew the tenant would play-in here too), I would tell the tenant I do not believe the contractor stole the property, the complaint has gone on file, and I will be assuming innocence until proven otherwise, or until a second complaint from a different tenant is made.

Duplex tenants would be responsible for landscaping whereas the fourplex will require you to mow the lawn or clean the stairwell and common areas.I would probably take the duplex just because it would attract families with a little more money and probably have fewer complaints of noisy neighbors, parking, etc.

If there is another formal complaint, I will evict them.
