What kind of cashflow can I expect from turnkey rentals?

[Jack B.]

I'm considering my options, as I sit on close to 1.4 mil in equity currently. One option is to cash out refi and invest in an apartment complex.

Another is to cash out refi and put some money into out of state turnkey rentals. 

I'm not looking to take all of it out, but just enough that I can get some more cash flow, while keeping my appreciating single family homes in the Seattle area.

So what am I looking at for:

1) Cost to purchase from a reputable place.

2) Cashflow after ALL expenses including PM.

3) Opportunity cost since these types of investments don't really appreciate.

@Jack B. - I should also add that I accrue 15% for maintenance and vacancy. Even with that Income is still $433
