Judging by http://www.theatlantic.com/magazine/print/2008/03/the-next-slum/6653/ http://www.theatlantic.com/magazine/print/2008/03/the-next-s... I'd say the probability is nonzero. And I'm pretty sure the owners described in the article will perform some critical maintenance like making sure vermin don't infest the house and fixing leaks because no one, not even a renter, wants to live in a place water rains down on them in their living room or where they have to dodge raccoons. Again, there are degrees of maintenance. They won't be incentivized to put in a new deck or repaint the whole house, but a lot of the value destruction associated with foreclosure has to do with simpler things: animals taking residence, water damage, thieves stealing the wiring/plumbing and ruining the walls in the process, etc.
