Cash Flow Question; Money set aside for vacancy, repairs, cap ex

[Account Closed]

From what I have gathered, if a potential investment doesn’t cash flow with 5% vacancy, repairs and cap ex then it should be a hard pass. We are looking at a property that MIGHT cash flow $50/month but I am also allotting 5% vacancy, 5% for repairs and 5% for cap ex which according to BP rental calculator will be roughly $700/month. Is the $8,400 that is set aside for the inevitable essentially cash flow for time being? 

Thank you in advance
