My question to y'all good folks: Do you know of, or can you recommend, a company or brokerage that deals in property management in California that I could work for full-time and learn everything there is to know? 

@Michael AddisonIf you're just getting started in Cleveland I would recommend being in areas on the West Side of Cleveland like West Blvd, Cudell, Old Brooklyn, Clark Fulton, Edgewater, Jefferson, and Brooklyn Centre.

The best way to get through the door with subs is a recommendation/connection from someone they respect.

Beyond trying to connect on this forum would recommend look in the BP Meet up section and checking out local DFW FB RE investor Facebook groups as well as Meetup.com and Eventbrite for local events. 

BiggerPockets also has a calculator to analyze deals, and I highly recommend you start this as soon as possible, even if you are not ready to buy.

I recommend having a contractor walk through the property before submitting your offer, or you could make your offer contingent on a contractor walkthrough.

I personally would recommend it but it isnt the best run 3 day. 

What strategies do you recommend for scaling my portfolio?

My property is fully renovated, furnished and ready for immediate occupancy, making it an ideal solution for families or individuals in need of temporary housing during their recovery process.I would greatly appreciate any insights, recommendations, or specific contacts that could help me effectively position this property in the disaster recovery housing market.I have one last question's lot of Insurance company stop writing policy in long island NY.

To get started - I’d recommend connecting with local STR investors and researching Hawaii’s regulations.
