How much cash flow are you seeing per unit in Akron/Canton area?

[Arthur Clark]

In the near future I will be using an FHA loan with a low down payment to purchase my first investment. I used the cash flow formula found on BP but it seems that the cash flow is small if not negative. What type of earning should I expect in the Akron area. Please see the example below. Let me know if you would make any adjustments to the way that I am calculating this.

I calculate a few of these daily  for practice. 

Highland square area. 

Loan amount $110,400

Gross rent: $1350 including $675 from a tenant and $675 from me. 

minus 

Mortgage $841 PITI

Repairs $100 ($50 per unit)

Cap Ex $100 ($50 per unit)

Vacancy $65 (roughly 5% of the rent)

$1106 in expenses 

$1350 - $1106 = $244 cash flow
