I own several Airbnb's in San Antonio as well as have a company that manages them.

We're looking to branch out to the Maine seacoast, but the rental management company we are working with says you're lucky to get 8 weeks in high summer and then hope to rent monthly (at a much lower price) over the winter.

This has a lot to do with the proximity of the hospitals along with the some of the big companies headquartered downtown. 

I also own a plumbing and a construction company, so if you have any questions please fill to ask.  

I would seriously consider at least getting a quote from your insurance company and then shopping around.

This year we are purchasing about 3,000 leads per month and skip tracing all of them so we have narrowed it down to a few companies we feel comfortable referring. 

Multiple, billion dollar companies are investing substantial amounts of money into our area, such as Intel, Google, and Amazon.

You're in good company.

In other words, a company looking for qualified investors gives referral fees, but a nonrealtor knows some qualifed investors who may be interested and wants to know if there is an agreement for that.I believe there is a name for that, and are there examples?

A landlord, the local grocery store and the utility company etc have no business whatsoever knowing a tenants  SSN and if I were you avoid collecting them.
