Would like to fulfill my children’s dream.

Im trying to buy a home for my 4 children who are tired of living in rental homes. A permanent,safe place to actually call  "home" for the rest of their lives. On disability income,we will never be able to afford to buy one on our own. One of my children have aspergers and needs his own space(room). I would like to buy them a home away from any violence in the cities,and where we can relax from the stress of moving around throughout our lives. Would like them to live where they can form longlasting friendships with others their age,be a part of a community and grow into healthy responsible adults. My youngest is 8 and oldest is 15.  I promised them I would oneday find us a permanent home to call our own,but with all the obstacles we have faced in life,I now am uncertain of our dream. Anything helps, and something is better than nothing. Thank you
