As someone who is renting, I have found that whenever there has been an intent to sell, from any of my LLs, I never stuck around to see the results and I felt it was an intrusion on the life of my family. Thus I bailed regardless of the financial situation of the landlord, or now nice they were… I am simply more distrusting of people by nature then most I guess… (Yes I am a landlord as well!)
In fact not only are there no signs of distress, but if there is not a disclosure of a short sale on the MLS, it may be that indeed they will come in with cash on the shortfall.
