They removed all their content from the web and I got an email from my coach saying she no longer worked for the company.

It will likely be a web of contractors, engineers, and architects, but some those are ultimately leading to the developer. 

An experienced broker with lots of choices at the palm of their hand is probably the best bet.

I’m not a betting man.

Quote from @Brandon Foster: Hello Ryan,STR is do able in the north county area but there are a lot of rules and regulations.The city of Oceanside right now will not allow anything STR unless it’s west of pacific coast hwy.This is changing a lot too so you need to be aware of that in your plans.Carlsbad is super strict too but there are some condos that are still available to do STR in.Medium term rentals are as safer bet but way less profitable.

If they have money and can compete on pricing, brokers will be the best bet.  

I like this, bet on the jockey more than the horse kind of situation.

From there, you can research through zillow/redfin whatever but your best bet would be to find an investor/agent (I a one but based in Fort Lauderdale) who can guide you through the process.

I'm betting he'd drive to that area.

You're best bet is to call a few brokers local to the area and see what they can come up with.It's definitely going to be a surplus or excess carrier that will do it and the premiums will be high.
