People are not careful and run too much grease down the drain and sewer clogs up, or baby drops a plastic lid in toilet that plugs sewer, $1200 later the plumber fishes it out after sewage backed up and ruined $1000 of carpet.

They are on a corner lot and inside their hillbilly fence they have 2-3 dogs, a dog kennel, a shed, a chicken coop with chickens (I think 5, which is allowable in our city) and now a duck as well as a plastic greenhouse.They do keep their yard mowed, but this fenced in menagerie is an eyesore.Would I be out of line to contact the landlord and ask him to PLEASE put up a privacy fence, so we don't have to look at all the junk these people have crammed into their back yard? 

Then to make matters worse after I’m already discouraged about my efforts as a real estate investor, I come home to find a dead chicken in my front yard wrapped up in a black plastic trash bag.

I'd try to rent it without it. at most,  go to HD and get a Sutter home or whatever it's called plastic shed for 650 bucks.  

Supposedly Delta puts more plastic in the fixtures that they sell to HD.

He did tell me though that I would also pay $200 to have a separate crew install a plastic covering on the roof from the inside of the house to prevent debris from falling through inside.

I have had this advice of a 6 mil plastic barrier in crawl space too. not for fungus but to decrease moisture.

I was l looking into bandit signs and saw a few videos on how to go to Home Depot to buy corrogated plastic sheet and to cut them to make the signs.

Aluminum wire has been the cause of fires, and may require special steps to reduce the risk.A local vendor producing plastic pipe years ago bought defective material that had been misrepresented.

I bet you can finance most of the project by returning all of those plastic bottles.
