Looking for an agent or companies to get quotes for home insurance services including wind coverage for 3 airbnb properties in Palm Coast, FL.Any help would be great!

I would talk to your servicer to see if they can assist you. 

Not going to give here a lecture on S-corps, but take my word: no benefits, only extra hassle and extra cost, such as preparing another tax return.

As the old saying goes, it's better to "get prepared, aim, and then shoot vs. shoot and then aim." 

Also doing all new plumbing and electric service/panel upgrade to 200amps.

When you have employees promoting the platform like it is the best platform ever and free accounting services, it was going to go down sooner or later.Pretty sure their other services are going to go down shortly.Baselane is offering assistance I believe, but they are just like Azibo.

How much of a credit do they offer at closing to cover the servicing fee?

Many ServiceTechs cover this via a service call fee. 

A debt service loan is popular for that step.

If you dont have time to do it yourself, you can usually rent the equipment and hire an operator hourly for less than what a full service company will charge you.
