The transfer of half of the house to you will have gift tax consequences for your mother to file a gift tax return.
If the goal is to avoid probate, then a trust is the best way to do that. A joint tenancy of the home assumes that you survive your mom and that you don't both die at the same time. Whereas a trust will provide for those contingencies.
