My father in law just sold his house and want to purchase a house with me and my husband. He will provide 150K for DOWN PAYMENT and we all together will finance the mortgage. A family member said we should not "purchase" a house with his name on it,because Medicaid can put a lein on our house. How can we go about purchasing a house together with out it affecting his medicaid eligibility? he does not want to "gift" us the 150K.
