It does not equate to non-functional toilets or no water or no heat, for instance.  

Your really investing in the property, the tenant is a small addition to the equation.

Our laundry for an 8-plex (2 bedroom units) only costs us about $160 per month in actual costs, including the use of our machines and all utilities.... which equates to about $20 per month per household.... and we don't even share the space with our tenants.

The software takes the human emotion out of the equation and tenants react to it like they would getting a bank fee or credit card fee which leaves little room for the typically excuses as well as having to deal with them.

Some landlords use a mathematical equation, called RUBS, to bill based on the size of the unit or other factors, this is just as inaccurate and down right illegal in a lot of places. 

So what is the risk of a $210K mortgage equal to in this equation?

The tenant would be responsible for seeing when they needed it and paying the oil company, and I'm out of the equation.

When it comes to service animals you are to act as if the animal wasn't even part of the equation.

I can't think of any other reason for that, except they expect that to be difficult = PITA.Maybe not, but in my life experience, you're way better off to deduct the reason is because the tenant is a PITA than some benign reason that equates to the tenant not being a PITA...And to anyone who is tempted to say something like, "Well, maybe the tenant is great, but the seller has cancer or whatever ----- my answer is, really?  

@James DeRoestI do most of my renovations in flipflopsThis is the perfect statement to illustrate the points of this thread.Being laid back should not equate to being unsafe.
