---The Oakland City Council is scheduled Tuesday to decide on a resolution proposed by Councilmember Lynette Gibson McElhaney that would establish a city loan program to help “distressed low-income homeowners” evict their tenants when the landlord or relative wants to occupy the property.Under this proposal, co-sponsored by Councilmember Rebecca Kaplan, the city would set aside $300,000 “to make available no-interest loans” to “cash-strapped” landlords to help them pay city-required relocation payments to tenants they are evicting.http://www.oaklandpost.org/2018/07/06/councilmembe...

I believe that was passed by the city council and subsequently thrown out by the court soon after as being unconstitutional

Just a thought. still suggest that given the city council just voted to ban STR in all but your primary home and even that for just 1/2 the year?

If you must form a partnership I think any competent council or CPA would suggest an LLC.
