You're in a quite a difficult situation here but the good thing is you have options…
What ever you decide, don't let the house stand empty for a long time. Try to see if you can anyone to rent it for the max price possible. Put out an offer, look around, negotiate… you can always say NO if they aren't offering you enough to make it worth while.
If you can't find anyone to rent it for a price that fits you, then sell it. There's no point in having to tolerate the negative cash flow for years to come on the mere hope of the better times.
