My specific questions are:1.

The California Secretary of State website can walk you through the process.   

This could be dangerous ground if full disclosures were not made and state specific laws were not strictly adhered to.

Hey Sammy, In Columbus, Ohio, your rental strategy—whether it's Short-Term Rentals (STR), Medium-Term Rentals (MTR), or Long-Term Rentals (LTR)—depends on your goals and the specific property. 

You can be a private lender and hold the first note.I specifically said not hard money lender unless someone recommends it.Mike, I'm guessing you're not a private lender but thanks for the advice. 

Hey Account ClosedI can't speak too much into the LA market specifically, all I've seen personally is that a BRRRR-strategy in LA is tougher because of property values.

Another option is a revised Tenant-in-Common agreement, outlining property management, expense sharing, and a potential buy-out provision in the future under specific conditions.

@Joe Rinellakeep in mind MA (all states) has a state specific tax code beyond the federal tax code.

Without hearing the details its hard to make a specific recommendations, but frankly, being under rent control, that's a 'pass' for me. 

Are there specific websites where I can find these or do I just need to search on mls?
