It seems like selling and renting is the biggest wealth builder in the end Rent in a lower cost area with a lower monthly payment and use the difference gained  to invest in the stock market ( which would yield around 8 percent) Keep the primary and hold it long term ( average appreciation in california from what I could see is about 5 to 6 percent if you look back in time Keep it as long term rental ,it would rent for $3800 current mortgage is 6150 $ - doesnt seem smart to me Let me know if you need any more details in order for you to give me a better answer or insights 

You are going to loose out on a lot of income by doing this .If your cleaner cannot complete a same day turn - time for a new cleaner You would if you were running a 53 acre ranch in Texas with significant additional logistical requirements and maintenance needs (both expected and unexpected) beyond what an average short term rental requires.
