Help the Muniz family with buying a house.

Just recently the my family received some news from their landlord that he is selling the house they are renting. Within 2 weeks they now have a buyer and an inspector is scheduled to inspect the house. With this inspection the house will be sold fairly soon. This house is being sold to a broker who will turn around and lease the house for a hirer monthly payment and new rules which may not allow pets. My family will be given roughly 6 months to find a new place to live. With losing my job due to COVID-19 back in April and having several health issues preventing me from going back to work this makes our situation harder. With the my family afraid of this happening again we would like to buy a house but we will need to come up with $7000.00 dollars needed for a down payment. With your help my family can secure a home of our own and not worry about getting kicked out of another rental property again. Please help and share
