Quite possibly, but I _personally_ found that working with my hands complimented working with my mind alot better than putting in 16h days of straight programming. The returns may not be as good as a second job, but I also didn't burn out.

Of course, that assumes that you enjoy the reno/carpenter/craftsman thing.

That said, whatever way that allows you to bring in the most (net) money in the least amount of time will obviously be the most efficient way to pay down debt.
