I would check out zip codes such as 44102, 44111, 44109, and 44125.  

Can anyone check this to see if I have made some Grave mistake and how to correct. 

Did you check FB?

Getting prequalified is free to do and is normally a "soft" credit check...so there's no downside to getting prequalified. 

If you are looking for just cheap properties, with decent cashflow and not much appreciation I'd check out the Dayton market.  

I know most of us have heard horror stories and/or have personal experience about criminals and unsavory characters taking over vacant properties then claiming squatters rights to avert the authorities. 

I knew the property was going to perform well- all the boxes were checked.

Property taxes - double check this assumptions here are reasonable in your cash flow projections.

I'd check out there calendar https://gareia.com/calendar-of-events/ - and see if there is anything close by to you!

I've gone through eviction court proceedings, ran thousands of background/credit checks for application, made numerous leases, dealt with repairs and whole house renovations when a few tenants nearly destroyed properties, and worked with property management companies on the HOA units.
