Hounding a Property Management Company

[Brent Sweet]

How often would you hound your property management company?  I just put one of my properties under a property management company so that I didn't have to self manage it.  I want to keep it that way.  Long story, but I want to be able to say to people my properties are managed by X so you have to go through them to apply and get approved to rent because I have some family that basically thinks I should just rent to them and they'd all be horrible tenants.

Anyway beyond my personal issues.  My property management company has been real good about some repairs I needed.  They got them done, were decently priced, didn't hassle me and took care of everything.  Right up until the property went on market they seemed really on top of it.  The listing is solid and they post it all over the internet.  I, however, have  been waiting and waiting for a tenant.  I emailed the other day and just asked how it was going, have they had any showings, etc.?  They said they had some showings but no bites and asked if I'd consider a move in special.  I was like yes waive the first month rent (I already made the payment this month anyway).  My issue is I'm not sure how often I should chase them without being a pain in the *** just to make sure my property is getting the attention I want it to.  I'm a little disappointed that they don't use yard signs (though I am not the professional so I don't know how effective that is I assume most people probably search online and they list everywhere there).  I don't want to be like the client everybody rolls their eyes when the number comes up on caller ID, but I also don't want to be put to the back of the line because I don't have 35 properties under their management.  Any ideas?
