City Certified Rental - Michigan

[Margeaux Appold]

Hi everyone - 

I'm new to investing and I recently completed my real estate salesperson course, and passed the test. 

I'm running the numbers on several properties, and wondering if anyone knows the answer to this question:

Does a rental have to be city certified before I can start renting it out? Some of the areas I am looking in have backlogs months long that I would need to wait for an inspector to come over to certify the property. 

Has anyone experienced this?

Thank you!
