What maintenance costs do you include?

[Dave Passey]

I have recently been seeing this quite a bit more lately and have been debating on how I should approach this in my own investing. I am regularly doing my numbers for maintenance on a deal and have been trying to determine if I should be including lawn maintenance and snow removal type things in my general 10% maintenance calculations. 

I feel like it is the type of thing that could potentially be passed onto the tenant in the right circumstance, but that is clearly not always the case. In the event that I am keeping up with the lawn care and general snow removal (if needed), should that be included in my 10% or should it be an additional amount that I am calculating in?
