There's easier fruit to pick.I heard a smart CPA/investor present a case for buying flood properties on the cheap because of the flood insurance for cash, not getting a mortgage and self insuring. 

My mother had one that would accept and grind up shrimp shells with no problem, but would barf all over any fruit peels.  

A good tree bears good fruit.."

A contractor gave us a box of fruit, pears, oranges and grapefruit. 

Look up "fruits of the land" which is the right of economic pursuits.

I might knock on his door with a nice gift- maybe a fruit basket or something, and just say you are introducing yourself to the neighbors and tell him how excited you are to be a part of his beautiful neighborhood.

To someone who invests in multi-family buildings, the apartment building will be more valuable.Really, that's like asking if you had an orange tree next to an apple tree, and both were prolific producers of fantastic fruit, which tree would be more valuable?  

Maybe offer a fruit bowl in the kitchen they are welcome to share.

That may well prove to be a more fruitful proposition than trying to sell a house with an uncooperative tenant, and dog hair.
