Help me save my home

Please help me reach one step further to buying a home for my family,after several years of renting I am now in the process of becoming a first time house owner I got the opportunity to finally purchase the said house that we are living in presently . We had saved and got the down payment and so far have covered all other document cost etc now my family and I are looking to raise money to get the closing and legal fees for the mortgage and am being told if don't have the fees the vendor can still put up the house for sale and my family and I may end up in the streets.We are out of savings and have no where to turn, no financial institutions or family believe me I have tried .We just can't seem to find this money any where and after reaching so far and all the sacrifice I don't want to lose my down payment or become homeless or the opportunity to have a house for my family. Also in this pandemic it has made it more difficult for me to do any other means of getting extra cash. I have never done this kind of thing but really desperate and asking that people donate to this cause out of the goodness of their hearts. May God continue to bless you and your family and keep you all safe and healthy in this Covid 19 pandemic.
