Is there a free grant for disabled single mother that will purchase and repair a used mobile home?

I'm a single mother who is staying with my mom and and the other five people that stay with us in a 3 bedroom mobile home. I found a mobile home for sale by the owner and he only wants $1650.00 for a 2 bedroom. I am disabled and need help to purchase this home. I wanted to know is there a grant that will purchase the mobile home for me and help me repair the home also?
