New Investor ? - Cap rates, etc.

[Jessica Fiesinger]

Hello everyone!  I am newer to investing and currently just own a commercial property, which I have a business being run out of.  I am looking to delve into owning and renting out multi-unit properties in the Cincinnati and Dayton Ohio areas.  

My question is before I get started, do you guys have set metrics for cap rates, gross rental yield, etc. that you like to always meet before purchasing a property?  What other metrics do you keep in mind to be sure it is a lucrative investment before purchasing?  I feel like I should have a set number of things I want before investing and am trying to determine those numbers.  Thanks in advance!
