WTB Liveaboard Motor Yacht (Marina Del Rey)

I'm looking for a lease option on a live aboard boat in Marina Del Rey, Santa Barbara, Oceanside or San Diego.
Looking to try living on the water for 6-9 months before purchasing a boat.
Prefer 40-50 feet with legal livaboard slip space.
Would like two staterooms and two heads.
I've been living in Hawaii most of the year, but need a place for my daughter and I when she is in LA area for her acting career.
LMK what you have - will consider everything.
Purchases up to $50k for the right boat.
Thank you for all responses.
