Too little cashflow?

[Rigo V.]

How much cashflow are you ok with? 

I am looking at a property duplex that would cashflow about 6k a year after piti and reserves (vacancy, capex and maintenance). Would be about 4k if I included property management but I plan to self manage. 

It would have enough equity to brrr it and would then cashflow only about 4K a year less with property management. 

Is this deal too light?
