Why don't you advertise 'FOR RENT' 6+ months in advance?

[Max James]

Is there a good reason why people don't advertise and market their units for rent well in advance of when it's time to turn it over?  I had great luck getting a leased signed in February for a July move in date.  I do not understand why people wait till 30-60 days to start advertising when they know the lease is going to end well in advance of that.  This way, you can also advertise for higher rent you think is within reason and if nobody bites, then drop it some.

How far in advance do you advertise and hope to get a lease signed?
