Mom wants me to take over her loan, how can this be done?

[Thomas Handy]

A little background on the story. I have been paying my mom's mortgage for the past decade or so. I pay the bank directly. She is retired and called me last night and wanted me to pay off her 15 year loan and take the property in my name. I don't want to come up with that money on the purchase since I'm fine paying the mortgage monthly as is.

Is there a way to legally take over the loan? I thought about calling the bank and see if I could assume the loan since I'm already paying for it.

Any suggestions?
Thx,
Tom
