Commercial property help with analysis

[Tony Velez]

I'm looking for my first commercial property. This property has a long standing nice Irish pub in one unit. There is another small unit upstairs. I'm not sure if its rented out yet. I will get more onformation tomorrow. My question is this? So far all the information I have for this property is what the realtor gave me. How can I find out the true expenses and rents for this property? 

This is what I know so far. According to the realtor. 

This is on a main busy road with a lot of businesses in the town over from me. I know the area very well.
