I am also considering trying them out as my 1st investment property.

I am also considering multiple rentals and it appears that I have found a pretty good property manager based on feedback I have. 

For anyone considering this, it’s probably worth consulting with a local land-use attorney or planner to navigate the specifics and make sure you’re maximizing the opportunity without running into red tape.

@Nicholas Dillon, a few things to consider:1.

As far as far as my research brings me, this is one of the zipcodes that is considered 'ok' in Detroit. 

They have good customer service, good online access, and take series LLCs.

I've considered a property management company, but the cost just doesn't seem worth it although it would be convenient.

If you're seeking a reliable income stream, you should definitely consider Cleveland.

Have you considered Arizona. 

However, you can likely sell all the properties in the required timeline to do the 1031k, although that will take some effort/cooperation between multiple buyers/brokers, considering the separate markets.
