House for 2 inseparable twins

I would like to be able to live in a house so that my twin sister and I can live together with our little family which includes adults and children aged years and the other month. Finally, all this in the Chambly area on the south shore of Montreal with bedrooms and a yard with pets allowed. I couldn’t ask for more to be perfectly happy. Things would be easier… Unfortunately we don’t have good credit so it’s very difficult, almost unimaginable!!!!
