I am sure that your Realtor has said this to you, and I am going repeat it and reinforce it:
If you are impatient, you should not be entering into a Shortsale.
If you are going to make life miserable for your Realtor by calling them and pestering them for the latest news; you should not be entering into a Shortsale.
If you cannot do these things, then do yourself and your Realtor a favor by getting the heck out!
There is NO NEXT!
The next word you hear may be six months from now!
Get used to it!
