Save Heathers house

My Aunt left me her house when she passed, inheritance tax is due and I have until November to pay it. I can’t get a loan, and an extension isn’t an option. This house has been the family home my whole life, I can’t lose it. It’s the only thing I have left of my aunt who was like a mother to me. I never ask for help, only want to help everyone else. I need help and I would appreciate any help. Advice and suggestions are greatly appreciated as well. I love all of you!
