New to commercial real estate and looking at buying another property. Need help.
Hi. I am new to commercial real estate.  We purchased a building back in 2019, renovated it and turned it into our current 3 story restaurant and is doing well.  It was kind of mad money, so the next one I would like to have a bit more education and make the landlord side profitable.  
We are looking at another building down the street.  Asking high 3s. Say 3.7mm. 3 floors and basement.  First and potentially 2nd floor would be restaurant (me), 3rd floor is leased to a hair Salon. 
What are some resources or how do I calculate the roi with this?
