Conflicting Advice: Need To Sell My Mother's House Without Impacting Her Medicare

TX

I'm trying to prepare for my mom's future medical care. My mother is considering selling her house to create a nice nest egg in her last years as it becomes more difficult for us to pay the taxes on it yearly. My mother has a Medicare Advantage Plan (Part C). She has not worked for the past 15 years. She lives with my sister.

I've reached out to some friends and received some conflicting advice:

• If my mother sells her house, it will have zero impact on her Medicare coverage.
• If my mother sells her house, it could potentially impact her coverage as it would be based on 1031 exchange rules given a 3-month window.
• My mother should deed over the house to me to avoid any issues.
• We should create an LLC, deed the house over to said LLC, and create an irrevocable trust to avoid tax issues.

My questions:

• Who can I talk to to get some help? Surely, this hasn't been the first time a scenario like this has happened? Do I need a real estate lawyer? Do I need an elder care lawyer? Do I need a CPA? All the above?
• Is there someone from Medicare that can talk about the tax and coverage implications?
