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

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.

Just drive to a high-traffic intersection and count the number of these hastily made plastic signs.The "BSI" matters because it is direct evidence of under-capitalized amateurs trying to get into the game.

I've also just learned about inserting a new plastic pipe inside the main and epoxy lining all the pipes.

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.

Transaction fees for plastic are always high.If you only have a few rentals, go to your bank and ask them for direct deposit instructions.

I rarely use the actual stakes as I tend to put them on concrete or inside, but they attract a lot of ants and unlike the Terro liquid that goes on cardboard, it doesn't dry out nearly as quickly as the stake stations (I also add liquid Terro to the tops and four corners of the stake stations to attract more ants).The plastic bait stations are also decent but if they're on even a slight decline they empty out all over the ground.  

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.  

Some even have plastic sheeting for skirting! 

A nice white plastic privacy fence, metal roofing, 3 other sheds, new a/c, home water filter system, just to name a few key selling points.
