Most brokerages do not require you to be a full time Realtor in order for you to hang your license with them.

So I shouldn't call mortgage brokerages, I should call mortgage companies?

Identify good brokerages and licensed R.E. professionals, and those who you send your marketing to.

I would definitely reach out to several brokerages within the area that could better facilitate as the middleman when Insurance Companies do reach out. 

-At the end of the day, if it were me and I was a wholesaler (as opposed to a broker/agent) in this scenario, I would say that "as a courtesy", you can try to help and see if you can sell it to someone else off market, but you should not be expected to do a due diligence for the buyer, that's their responsibility, and you said from the beginning that you are not knowledgeable on land. 

It's like real estate agents, the bar is too low, but the brokerages like it that way because they make money off the agents who do no deals.

Can name their brokerage in there also to go after insurance. 

Also the brokerage business is a relationship business.

One of my best friends owns one the largest brokerages in Miami, she says do not touch it, its going to crash. 

With the idea of "we can turn money today into more money tomorrow by investing it," I place most of this within a taxable brokerage account where it grows based on the market broadly speaking.
