Tenant 2 on the other side has supposedly been living in her unit for 20 years, and she currently has a roommate.

I would screen her first so you know who will be living there but assuming she's ok, would just add her as an occupant as opposed to a responsible party to the lease.

Here his videos

Most of the area it’s only allowed WHILE you are living in the unit as your primary home.

I also never looked at it as a way of quitting my job; to me, I think it would be more productive to just find a more profitable way to make a living that you enjoyed. 

Also, the state of formation is likely where internal disputes would be brought among LLC members, so if you and a partner and/or spouse live in CA, you probably want to arbitrate in CA if the two of you had a disagreement.

I caught the bug two weeks ago and have watched about 50 videos lol.  

We are planning to live in the owner's unit and tenants above have lease that is expiring mid 2024.

I also grew up in Cupertino and lived in Palo Alto Napa valley prior to Oregon..

Was trying to post a link to video that explains using single source funding to do a double close but it won't post.
