First SF Home has been vacant for 6 months! Help

[Martin Warren]

I signed up with a property manager to lease and manage my single family rental and it has been almost 5 months and still no renter.  This is a very reputable property manager in my area (several people recommended them).  I have asked them if there is anything I can do to help get it rented and they keep telling me that it is a great house and they are confident that it is priced correctly.  They have already dropped the price by $75/month.  From what they say, they are showing the house 3-4 times a week but nobody has put in an application.  They even told me that houses in this price range are the easiest to rent back when I signed the contract.   I have an investor friend that owns three similar houses on the same street and he has never had any trouble renting them.  Is this common?  Are they not doing their job or does this actually happen a lot?  Do I have a crappy house?  Can I get out of this contract?  What can I do?  Thanks.
