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

Did you check FB?

Quote from @Jay Hinrichs: maybe make it like a Lenders license I have U have full fbi criminal and personal financial and credit report.. does not mean you have to be super star but just cant be bad.To get my GC in Cali, I had to do a full fingerprinting and state and federal background check.

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

This is how hotels often catch people faking service animals, as the person checks into the rooms, and then immediately leaves for 5hrs and leave the dog behind.  

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

For context, I have a business degree in marketing (not good I know) and work for the biggest single family rental company in the US doing entry level customer service.

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

@Joseph Weisenbloom - I normally don't counter sign leases before receiving cashier checks or the funds in my account for the security deposit and first months rent.

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