San Jose did as an example and there are a few resources they've put out. 

I’m in the San Diego area and my husband and I are adding 2 additional rental units to our property. 

Hi Renee,You’ve built an impressive portfolio, managing 100 units in San Diego is no small feat.

I would think transient room mates on renewable short leases would be much safer than bearing the brunt of San Francisco's LTR tenant laws.

Like I brokered a 22  lot development of duplex's for a builder and just charged him 30k flat fee per sale.. they sold for 225k each back in 05 when I did this and I sold them all in one weekend at a big event i paid for in San Jose CA.. all to CA investors it was my fly and buy program I did in those days..

. - The ultimate house hack, live in the small ADU unit and rent out the two levels of the main house on AirBnb in San Francisco (I would have thought STRs are oversaturated in S.F. but it worked for them and they stay fully booked).

I currently live in San Diego, Ca. but have been looking in the midwest, mainly Iowa, Indiana and Ohio, for properties. 

Hi Jerry, yes, San Francisco has some great limitations on STR's.

Secondary Markets Are ThrivingOmaha and San Antonio are two examples of secondary markets where the cost of entry is still reasonable.

@Josue Ramos I would recommend areas like DFW, HOU, SAN, OKC, Tulsa, Memphis or even Little Rock.
