Trying to Save a House

Me and my sister helped each other to pay for a house but recently we both lose our jobs due to the drop in oil price. We both worked in construction office job abroad and last 2015 I was sent home and my sister lost her job too. The house was intended to be for my sister and her kids when they finally come home because she plan to send her 3 kids to university here in Manila. I recently got a local job but its just enough for my rent and expenses. My sister is still unable to find a new job where she would afford the monthly amortization. I tried to help with my savings on months where we both have no jobs but recently all my savings are gone. It saddened me to lose that house because I want all my nieces and nephew to finally come home but we are unable to pay for months now and between the two of us its only me who has a job. Apparently the monthly is too high for me to pay because I also provide for my mom plus some bills. I would need some help until we are both back into a decent paying jobs so we can continue to pay it. I would appreciate any forms of help extended as my only wish is to have my sister, nephew and nieces back home. Some of the amount I would use for their flight ticket back here and to pay monthly amortization while we search better job. May God bless you for all your help.
