Where I am, it is my opinion that multi-unit properties are less risk, in that, all of your eggs are not in the same basket. 

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. 

When tenants move in, I always have a small care package for them, some basic cleaning supplies and maybe a laundry basket.

Many of my "eggs" are in one basket so to speak, but this is simply the condition of my market in which I live. 

They love dog food and the fruit tree is good source of food also.Tell tenants not to leave any dog food outside..  

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.

I was thinking of a gift card for a dinner or maybe a place like Target for supplies in a card or gift basket.
