Help me to buy a house for me and my family

Since forever I was born, my mother, my brothers and I live away from the rest of my family. My grandparents, aunts and uncles, or cousins ??all live in the same town near Versailles, France. My mother has worked hard for years, and  has tried to save money in order to one day buy a house in this town. But life becomes more and more expensive, and the prices of real estates continues to grow.However, a house has just been put on sale in the same street as my grandparents. We would really like to buy it, but with the money that the bank lends us, we miss € 80,000.I appeal to your generosity, so that my mother can finally buy the house she dreams.Thank you in advance.
