Good questions!
* Unfortunately, when either McCain or Obama is elected to the Presidency, it’s not a far stretch to see that the door to legalizing all the illegals that are already in the USA will swing wide open. So, once they’re legal (Probably within two years after the election), this will open another door for new government programs to help the poor immigrants find a low cost home. I can see it coming like a Greyhound Bus coming right at us.
Of course, as values continue to fall over the next couple of years, investors will buy many of these properties and convert them to rentals.
That’s my vision through the crystal ball. YMMV 🙂
