son and daughter-in-law of dad

(waterloo ia)

my husbands dad is in a nursing home. his house has been sold. his dad holds the mortgage on our house that was purchased in 2004 with the agreement we pay the mortgage and all expenses involved with the house. we have pay all mortgage payments and all expenses including improvements and the cities demand that we replace some sidewalk. the will states the houses goes to us upon his death. my husband brother and sister-in-law have poa and have demanded us to get out since the day dad went to the nursing home. he will soon be applying for Medicaid and Medicaid of course wants it sold to. is there a chance Medicaid will accept money from us so we can keep the house
