Technically your mother's ownership in the home that you are writing about may disqualify her for section 8 housing depending upon the value of her interest in the unit she owns with you. Whether or not she can still receive section 8 housing and own an interest in the unit she has with you is something that can only be answered by reading the qualification requirements for section 8 housing.Your mother can quitclaim her interest in the unit she owns with you. Before that is done, I suggest that she consult with a real estate attorney on the subject who has experience with section 8 housing requirements.
