I invest, flip, and own a property management company in CT. 

I personally recommend checking Columbus OH - lots of job growth, population growth, and major companies moving and developing here.

Maybe consider getting a p.m. company that would do some boots on the ground and some research for you to find out what some of these issues could be because you are not close to the residence in the location, unless you can do some research yourself online, or consult with the historical Society of the area, look things up at the library, there are lots of different ways that you could start this process, but my point being that you may end up losing more money in the long run.

Or hire a PM company to manage for you?

Just google all the property management companies in your area.

I also invest in other assets such as stocks, and private companies as well.

I've been following 'howtoadu" and that was mentioned by a construction company that builds ADUs. 

The insurance policy must name [Landlord's Name or Property Management Company] as Additional Interest, ensuring the Landlord receives notice of any policy changes or cancellations.

My top recommendation is to begin by contacting property management companies in each target area.

It took some digging, working closely with a title company, and negotiating with multiple parties to get it resolved, but in the end, it was a great learning experience—and a successful deal!
