Advice Needed - Purchasing Parents Home

[Ketra King]

Hi all. My father recently retired and he's struggling to make ends meet. My parents owe about $20,000 on their original mortgage on their home, and there's a HELOC with a balance of about $40,000. The interest rates for both loans are variable and constantly increasing. Making it harder for my dad to pay now on his fixed retirement income. They could potentially lose their home, and I really want to help. I am a newbie in real estate investing and I have no idea of where to start. I was thinking of potentially purchasing their home to get a better mortgage with fixed rates and a better monthly payment. I would have my dad pay that mortgage for as long as he lives and then take over the payments. Their home could potentially be an investment property for me in the future. Not sure if this is the best route to take, but I am open to opinions and suggestions.
