Analyze hair salon purchase

[William Walker]

I'm close to purchasing a hair salon - this would be my first commercial investment. I'm familiar with residential and own a few SFH but this is new.

Purchase price 100k

Rent $1,200/month

It is one building with 3 units that do not connect. Each with its own meter and bathroom. There is a sort of HOA (I'm sure not the proper term) that is $100/month that covers outside maintenance and insurance. The unit is currently being run as a hair salon with chairs, mirrors, etc and would directly roll over to new tenant.
Liability insistence for 1 million is 200/year. 
My current wall is financing. I am cash heavy and can put 25% down no problem, I spent a long time today calling lenders and I’m having difficulty finding a commercial lender. I’d like to do 15 years with 20-25% down. 

What else do I need to be considering in the finances other than taxes?  Do the numbers look profitable. This is in Wilmington, NC in a busy area with a good amount of traffic. I confirmed rental rate with 2 separate hair stylists that confirm it’s an appropriate rate. 

Any advise appreciated.
