Seems like the vast majority of owners interacting on this and other platforms are from the Smokey Mountains or FL.

I think DSCR Loans are definitely in your future as you continue to grow your portfolio but probably not the best fit here:-Can strictly not use DSCR for any property you live in - would technically be possible if you moved out, leased up the unit you are currently in and provided good documentation that its legit - but this is a firm non-starter for DSCR (absolutely no occupying the property)-DSCR Rates at best are in the sixes on a cash-out refinance - so you would be doubling your interest rate at least on the current property - which could make sense but its a pretty high hurdle.

I am seeking a property management tool to schedule showings, screen tenants, collect rent, and allocate maintenance requests to one centralized platform.

But, I wonder if being an city-approved Airbnb host with a legit registration # is enough grounds to stand on legally if an Airbnb client reports/sues me because of, I don't know, a medical injury because of hitting their head on the short ceiling (even if I disclose info about the ceiling upfront on the listing).

We've been using Innago for years and we love their platform.

Lastly, if you have a large social media presence, you could simply promote the open house on those platforms. 

Utilize platforms like BiggerPockets and other social media to source your team.

Any recommendations on a platform to use?

Launching a new platform in April that will democratize real estate investing education, information and lending. 

You take care of California - we got Texas.Anyway...whatever you tell yourself in the mirror to make yourself seem legit is ok with me.I have no hate.
