Help us buying house for our four litlle kids

We are living in house thats been sold and we have only 3 months to get another house. We cannot rent house becouse no one is willing to let 4 kids to live in their house. We are both unimployed and we do not have enough money to buy house. House in our city and in near circle its more then 250000e,and with 4 litlle kids and with no job we cannot take credit in bank. Our countri is giving us only social help and that is all. In few months we are going to be living on street.
