I especially am unsure because I am new to the NJ market and am not sure if the costs drastically change for location/supplies/labor/etc. 

Supply & demand, too many people coming into the note space paying too much, which will cause them to make low gains and hopefully motivate them to find the next shiny object. 

You have Ohio Revised Code working against you anywhere in the state and you have all the water supplied by the Cleveland Division of Water who supplies water to almost every city in the greater Cleveland area.

Nor do we ever supply a tenant with a lawn mower, chain saw or even a snow shovel!  

The idea of going to a Benjamin Moore store or painting supply store isn't a bad idea... 

Back in the day of having a JOB I spent a lot of time on the road so our company librarian would supply me with any audible books I requested.

As for the tenant, if you are supplying window units temporarily, they have no leg to stand on.

I am a farmer, from my perspective farmers are squeezed about as tight as they can withstand before some farms fall and supply/demand equilizes.

And while I love my job, my business partner and team, my clients, and the business itself... the music business is very a much full-contact sport.  

The contractor knows hes going to be paid because he can do a Mechanics lean on the property.I would only do this if I was directly paying the supplier and the supplies were delivered straight to the job site.
