Why is Bristol Palin buying property in Arizona?

News has come out this week that Bristol Palin has bought a home – in Arizona, of all places.  She paid cash for the $172,000 property, located in the suburbs of Phoenix, and this has prompted a lot of speculation as to what she’s planning on doing with the house.  The current favorite theory is that Palin is planning on attending university at Arizona State, and she’s trying to settle into the area before she goes back to school.

The university has not commented on whether Bristol is enrolled or in the process of enrolling there, but it seems unlikely that a Palin would buy a house in the lower 48 unless there was a good reason for it.
