It's by a company called Stonefeather Marketing and automates audience building on FB.

Those companies you asked about are more for deal finding and direct contact to off-market sellers, is that what you are looking for? 

There is a "sponsor exemption" but that only allows an unlicensed person to raise money but it cannot be more than 50% of their duties and the pay they receive cannot be based on how much they raised.If you have never raised $, a family office will be off the table as they typically want the company to ahve atleast $50-$100M in assets. 

My insurance company sent guy to inspect once.

How does the transaction work between me personally and my holding company LLC?

I like smaller companies whose owners are not brand new but not old and burned out either.

It may sound nice to pay a 6% management fee but the extra fees can add up to be more than the other company that charges 10% with no additional fees.

Currently my short-term management property is managed by the property management company.

I own an HOA management company in Hoboken and it's led me down this thinking-path as well.

I will note though that lots of people manage multiple rentals without hiring a STR management company (myself included).
