What's the best way to proceed?

Ok, here is my background:

My wife and I live and work in Qatar and have since 2006. Our family income is around 140k, with housing provided here and no other debt (besides the house mentioned below) we keep about 100-110k of that as Net income. We also have no Tax burden at all.

I just purchased my first investment home Aug 2007 and had renters move in almost immediately, we get $1100/m with $88 of that going to the management company. We paid $225000 for the house, we financed 168k of it at 6.35%/15yr.

Here is my question, with our current family income I can pay the house off completely by June 2009 (This has been my goal but have been re-thinking thigs), is that the right move? If not what should I be doing instead?
