as the subject says I am getting out of the navy in 9 months. (oct 2009

)
by the end of that 9 months ill have a little over $20,000.
along with $5,000 or so in stocks.
out of that $20,000 at most $6,000 is going towards a ring and wedding.
we get married in nov
she is still in the navy so the house is taken care of. there is no need for that.
i dont know her income (it goes up if she is married)
and i have know clue as of what work I will find in Florida.
she only has a yean and half left in once we get married.
we are looking to build a house once her enlistment is up.
i haven't figured out if i should work two jobs or one.
i'll make a decision based on her underway schedule
besides saving pretty much everything.
what else can we do to save for a house?
we are both young and her debt will be taken care of by this time.
tips, tricks, and advice are welcome
