Well, the big question is "What are your goals?" Both short term and long term. And what does your wife think bahahaha. But seriously.
What would be your reason to move? Bigger better house? Better neighborhood? Do you have kids (or plan to have kids) that these moving plans might affect?
Also, another thing to consider is what a second home is going to cost you. And what your home would rent for... and if you'd even be able to get a loan for a second house. Best to talk with your lender and see what might be possible.
If the long-term goal is to own multiple properties, and buying a second house to move into won't cause you to get into debt up to your eyeballs, and you can rent your current house for enough to cover all the bills, then go for it.
But depending on your family plans, that all might be different.
If you let us know a little more, perhaps we can give you better advice about buying a second house in Phoenix.
