If you put the house in her name and you have siblings or other folks who would have a claim as a direct heir on her estate, you run the risk of losing the property to another heir. 

That's the direction I was looking for.

I would start with them.I am not based in LA, so I don't know your exact laws, but I think I can still provide some initial direction for you to find answers, and maybe offer an idea to research.  

Whether it's optimizing listings on OTAs, leveraging social media, running targeted ads, or using dynamic pricing tools—I'd love to hear what’s working for you.Some strategies I’ve been exploring include: Enhancing property listings with professional experience photography and compelling descriptions, leveraging Instagram and Facebook ads to attract more direct bookings, and utilizing email marketing to engage past guests.What’s been a game-changer for your vacation rental business?

Or you can directly meet them by registering to real estate events around you: https://www.biggerpockets.com/forums/521-events-and-happenings 6.

Was it through networking, direct-to-seller marketing, or just keeping an eye on the market?

The first time they break rules (unless it is a direct danger to people/property) I have a kind chat with them and make sure they understand what they did was against the rules.

They are familiar with you and can give you direction and documentation.  

I would push for very low or no money down but having a Realtor that needs to have their fee paid it may still not work.Look up the owner if possible through truepeoplesearch.com and call them up directly.

Or you could go directly to the HR departments of these companies.
