The area I was in was a heavy medical and college district. 

- Do you have any advice for first-time investors tackling a rehab-heavy property?

I understand certain neighborhoods in America will be heavy to section 8 and its preferred as the market tenants tend to not pay .

Heavy duty, old fashioned machines that don't have motherboards or other electronics that tend to burn out.  

Construction can have unforseen costs, construction loans for rounds of funding can be more expensive over time, rent markets can drop, vacancies in market can increase.Typically entitlement phase of land most risk, followed by development, followed by vacant building turn around, followed by half vacant building, followed by mainly full building with value add component, followed by brand new building with market or below in place rents and everything new with good location.Along that spectrum of course you go from heavy equity upside potential to mainly just the cash flow return and hopefully price appreciation over time.Investors have to decide on the spectrum of their risk assessment to capital over what period of time how they will allocate between all one type of investment or multiple and what percentages.

If things got heavy I would tell them to follow the lease and send their complaint officially in writing, and I will respond accordingly,  usually that ended it.

BP staff confirmed it was a heavy swing, not even considering the whole hurricane aspect. 

These are heavy-hitter, regular buyers.

I like Columbus because of the city's massive growth, but other markets like Cleveland will be a little more cash-flow heavy. 

Depending on the size of the ADU vs the main property, you would probably be looking at either a "heavy rehab" loan - or a "ground up construction" loan.
