, lack of fence above bricks is a safety issue (is it up to code?).

Take photo from at least two different angles so I can see every section of fence, all trees, etc.Exterior photo of all four sides of the home.

I thought a great value add would be to add a fence to buy units (with a divider).I'm trying to decide what the best kind of fence would be: pine vs powder coated chain link?

I will tell you.You , Me, him , her, that guy that wants to list their house,  that guy that wants to sell it himself, that guy that wants to sell it to us for cash.YES EVERYONE wants to sell their house fast.No one wants to sell their house slow.It is NOT about search volume, it is about MOTIVATION.Those that look for keyword volume, no offence know NOTHING about lead gen.What do you rather have?

Withholding rent is a unforgivable offence in my books and clearly indicates a entitled individual that needs to be terminated with prejudice. 

And I am ok with that, again due to my financial goals and personal plan.I mean no offence Michael, I absolutely agree with the first half of your post. 

The city employees pick the sign up, then charge a littering offence for each sign to cover their costs---and the signs have the handy dandy phone number of who to site on them!

Is it possible to put up some kind of fencing so that they cannot damage the property?

Like one section of fencing that's the exact width of his gate.Just kidding.

Sorry you took offence, Look at all my response, very direct, tough love :) NOT here to discourage, Yes  I read it as you do not have the funds, If you do then there will be no issues.
