That is a good question and the answer depends on local practice. If your mother continued to live in the home, Medicaid may consider that your mother made the utility and tax payments in lieu of rent rather than as gifts to you and your brothers. In other words, instead of paying you rent, she paid the housing expenses. But to be sure, you’ll have to check with a local elder law attorney.
