A new home for an old soul

I would like to ask some help from you guys to help me with finding a new home for me and my parents. I am an only child and my mother works as a house maid for more than 35yrs and my father has a health issue thus making him unable to find a job. My mother's wage is only 4,000 a month which cannot cover even the half of our monthly expenses. As for me, I my salary is above minimum but with the declining health of my grandparents I am also shouldering not only our families expenses but also my grandparents basic & health expenses.Since I am the only child I am responsible for all of their needs and with that reason I can't even save up enough money for even the downpayment of the house's that are being offered in our country. Me and my mother have been living with my mother's employer ever since but since they have been planning on living with their daughter in abroad and selling the house which we live in soon, this will result us to being homeless soon .My father have been living in some small house in one of the slum areas near our place. Being both of them almost senior citizens I am dreaming of giving them atleast the comfort of having our very own house which we can live together for the rest of our lives . I do hope that you can help me in fulfilling my wish for my parents . Thank you in advance and may God bless you.
