If you are losing money on it every month, it would almost certainly make more sense to sell it, and apply the money you'll be keeping to your savings. I don't think it's worth throwing away money every month based on the possibility that you might one day retire there. Condos generally don't hold their value as well over the long term as freestanding homes (well, maybe in Manhattan they do), so aren't worth betting on appreciation, and you are stuck with HOA fees and HOA hassles for all eternity.
I say sell and invest.
