When I went to rent, several neighbors called the City and reported me.They claimed I am devaluing their property values.

I think I could do well with it on airbnb, a neighbor has been doing it and is cleaning up. 

Hi Marc,I'd assume it will draw a particular type of tenant, and a particular type of criminal.Plus you could only enforce it after the fact, and would it stand up in court (Constitutional Right, will they evict for that).And would you be opening yourself up to a lawsuit for not being diligent enough in enforcing it when someone shoots through a wall and injures a neighbor?

You might ask a neighbor. 

After we purchased the property, we found out the neighbors are wanting to sell their house too.

How to find buys? This is my first deal.

I have tenants in a rental property and they are having trouble with the neighbors.  

You had a verbal agreement with your father and you fulfilled it.  

I already had a case that someone asked me why i approached her and not her neighbors. 

I grew up in Woodland Hills... howdy neighbor!
