Hey guys, I'm the founder of Future Media Management, an internet marketing agency that is mostly me and a few friends allying as freelancers and doing marketing for private clients. 

I knew it was a wise idea to purchase houses here as then one could buy a house outright for not much more than $10K , but the most we could get in rents was $30.00 USD equivalent/mo. so we decided to pass on creating rental income but lately Airbnb has contacted us on renting through them at an average rate of $100.00 per day to vacationing tourist and that does sound attractive though we have not actually signed up with them yet but we are certainly thinking of trying it. 

These can be an attractive starting point, given their reduced price point for entry.

But the deal and the number look very attractive, with possible ways to make improvements.

This is a long-term hold, which steadily increases in value and attracts quality renters.

You probably would have been fine with investing in SFRs in Cleveland Heights, or with investing in apartment buildings in a less fussy city (like Cleveland proper), or with investing in apartment buildings in a city that attracts higher quality tenants in apartments (like Lakewood or Lyndhurst). 

So look for areas that attract people.

@Brooklyn Ron great questions, the fundamental basics are your knowledge in real estate and ability to use that to attract the right partners and capital for the deals.
