Unfortunately, just being placed on legal title to a home after a loan is already in existence does not entitle you to automatically assume the loan. I suggest that you carefully read the loan agreement that your mother has for the home that she is in to assist you in understanding whether or not the loan is assumable.I suggest that you consult with a Wills and trust attorney about the best way to have your mother's home transferred to you upon her passing. To get a stepped up basis, transfer of title should either be by Will or a trust.
