@Chad AcerboniConsider this a list of the top companies I would recommend in general.

Some common names you'll see thrown around a lot: Stessa, Apartments.com, RentRedi, TenantCloud, Innago, RentManager, Avail, Rentec Direct, Doorloop, etc.I recommend you search for each of those apps online and see what they offer, how much they charge, etc.

So, if interest rates are a buyer’s primary roadblock, then I recommend seeking opportunities to negotiate a rate buydown at a seller’s expense or looking at new construction, where builders are offering rate reductions and other substantial incentives.What if I’m a seller?

Any recommendation on building a team, accounting, etc and how to do this?

@Alex Shaughnessy Unfortunately, I don't know this company, nor do I have any PMC's to recommend in that area. 

I recommend you incorporate some of these and start systemizing your portfolio as early as possible.

I recommend looking into areas near economic bases - close to Nationwide Children’s Hospital, Ohio State Campus, New Albany, etc.

Did you work with any real estate professionals (agents, lenders, etc.) that you'd recommend to others?

I would recommend always use an attorney to draft your documents and use a title company to close.

I talked with a lawyer but I am running into the problem that his recommendation seems to be what is better for him, so also in search for other real estate lawyers in the area.
