How Soon to Tune?

Greetings, 
   This will depend on the quality of the service.  I suggest two weeks.   
This allows the piano to cycle through the household's day/night changes, and 
generally get acclimated to the relative level of humidity at that time.  
    A larger reason for the wait is that two weeks of play will call forth 
break-in problems like damper pedals losing regulation, "sticking keys", 
maybe a jack pad that didn't really have enough glue will have fallen off, 
and the damper wires that moved early in their settling will be rattling.  
    A couple of weeks delay in that first tuning/service can save extra trips 
in the first two months or so. 
Regards,
