Rent Ready Time from tenant vacating to back on the market

[Robert Burge]

If you know the date when the property will become vacant, how long should an investor wait for their property manager to turn the property over and get it rented?  I have waited just about 2 months now for them to get the property back on the market and it still is not ready to market.  Am I being unreasonable?  It didn't need a heavy rehab, and I am not referring to it sitting vacant on the market.
