Property management/LLC formation/Collecting rent

[Alvaro Tuchan Jr]

Hello, my father recently made his single family home and is creating a 4plex in Los Angeles, CA which will be done in approximately 1 month. I have offered manage the property, since I want to begin real estate investing/STR in the near future. I am looking for advice regarding if we should create a LLC/corp? Depending on the answer to the question before a business account vs separate personal account? Efficient ways to collect rent? And other pieces of advice or book recommendations would be greatly appreciated.
