The macroeconomics for Columbus Ohio are on fire especially with population growth, job growth, and companies moving/developing here so there's amazing appreciation as well.

This is the value of having someone who has local experience.The company you said, if they are some "remote" company, I guess they could provide the things that you need and save money, but I would hesitate to feel confident if they do not have regional experience and that you would be left vulnerable if issues arise with the design later on. 

I would also check out NARPM for a list of local property managers. https://www.narpm.org/about/why-use-a-narpm-memberBest of luck!

Check with local realtors for handyman recommendations. 

I did not pay for the course or get any deeper because I figured 1) High return = high risk, and I am at a point where I can't afford to lose that kind of money; and 2) I didn’t see a value in a course- why not network with local investors who need down payment, and work it out directly on a deal that I could more easily underwrite?

I would talk to a local bank or mortgage broker to see what you can get for a loan first and then go from there. 

You can also check with a local independent insurance agent to see if any carriers that might not have been mentioned have a short term rental endorsement that they can add to a standard landlord policy (Travelers does in the states I write in). 

I may look at out-of-state investing in the future, but I think good deals can be found locally (which I think you acknowledged). 

Overall, it looks like a good deal, something you could probably even take to a local bank or credit union for financing.

In my area of NC, our local MLS's are writing rules to prevent wholesalers from being able to list and sell a property they have under contract.
