I was considering hiring a professional (based on one of the podcasts I listened to), but I'm not sure where to start.

I am going to hire them to do a home inspection.  

If you don’t want to be as active in your property’s management (i.e. you’re not cut out for “by owner” management), then hire a good property manager to handle the nitty-gritty details like prepping the home for the next tenant. 

@Patrick Philip  you can alleviate all of your concerns by hiring a professional general contractor.

If you want retail and industrial lease forms, you're probably going to either need to hire a lawyer or find them elsewhere.Also, forms of that nature might be state specific, as state laws can vary from state to state.

After reading the clarifying language for opportunity zones, it seems as though a newly formed real estate fund could buy an office building in an opportunity zone and hire employees to help run the fund (they work in the OZ).

Have you talked to an attorney, or were you hoping to save money and not hire one?

So you could have hired a lawyer and evicted, but instead you gave them three free months before you now have to hire an attorney to evict them?

Hire a real estate agent.

They can transact real estate, hire and fire RE agents, make and originate real estate loans, as well as sell them to the public.
