My mother land got indebted in bank

Hi ! Im Girlie Macagaling (facebook.com/m.ghe826) I need help financially.My mother land got indebted in a bank...amount of 450 000 in peso(Philippine money). I have no one can borrow money because its too big so nobody want to trust and my salary is not enough to reach the amount.The bank said it will be porfeited for good.(Begged for the second time and this the last chance).My mother is 72 this year.she doesnt want to give up the land because its her and her late husband(yeah my parents).I have no other choice of calling help .im the 6th and the youngest and my elder siblings no help can do too.
Im the last person my mother really can rely on.
I really appreciated cents or any amount because its a big help when it all combine.
Thankyou so much in advance and
P.s sorry for the grammar☺️
