It looks like a pricey investment but I'm not super wealthy and don't know anything about container construction. https://www.columbusnavigator.com/box-hop-hocking-hills-airbnb/

Where/How do i find the best portable storage containers? 

Have they got this contained?

NOTE: Please be warned that the images contain pictures/videos of inside a toilet!!!

I mention that because your post contains none of the information that would be needed to know which calculation is applicable. 

The property isn't in too horrible shape.Now, here's the question:There is a posting on the window, a warning stating that this property contains mold.

This is why they are building the detention ponds and culverts to contain the water.

State law really affects your question regarding the collection of late fees.In my agreements for properties I own, manage, and sell with owner financing in Texas and Colorado, my agreements contain the following:Payments are first applied to any unpaid obligations such as late fees, service fees, any other associated fees, or monies owed to the Seller under this Agreement, then lastly to the lease payment regardless to notations on checks or money orders.In this way, if a late fee is due under the agreement, the agreement is in default because the entire payment was not made unless the late fee, and all other fees have been paid.Thus, you can legally evict or foreclose.Again, state law rules.

But you will have to make more passes since the coverage stripwidth is only as wide as the container on the drop spreader.

Let's hope they find some way to contain it asap.
