What should I request from seller when making an offer?

[Jonathan Nguyen]

I am making my first commercial real estate offer today and was wondering what I should request as part of the offer. I am putting subject to bank approval, copy of all expenses, profit and loss statements, half closing costs and some basic stuff. 

I was wondering if it was unusual or even possible to ask for warranty on the building appliances such as the ac units. I am used to residential and when buying homes on the mls I've got places to buy a warranty for them. 

Is there any other tips or things I should ask for as part of an offer?
