Debt free before buying

I'm sitting in a place where this is possible. Finally hubby and I are on the same page financially.

Do we move into smaller rental for a year and attack the bills with the extra... Or do we just pay what we have in collection and keep paying the revolving lines i.e. Car payment and student loan, on time, perhaps with extra on principle every paycheck and when we hit the magic number buy?

I need an adviser who knows what they are doing.
