Hospitality, attention to detail, cleaning/handyman team, programs used for bookings and calendar organization, inventory audits, home maintenance, etc. are all extremely important but all of that doesn't even begin to describe all of the things an experienced property manager does.It is a matter of how much time and energy you have to invest in your properties and if that time and energy is worth it to you.

From my experience, Aircover has been covering loss of income if there were bookings for those days. 

Also, many may disagree with me here but in my book, a smart and savvy attorney can make the case they are alleging.

But if anyone can recommend a book, a podcast, a youtube on how to start in AirBNB will be so much appreciated.

You could check out a book by Dave Van Horn called Real Estate Note Investing.

@Raul Velazquez The 3 things I would recommend besides reading books/audio/sites are:1.

Zoho Books, I am not using this as my partner uses it integrates nicely with CRM for book keeping and I could provide access to our CPA for Taxes. 

I was just reading Mark's book "The Tax & Legal Playbook" this morning and it specifically had a "critical warning" (page 31&32 in Chapter 3).

Just make sure you are saving towards those slow months during the peak months, buy a deal at the right price (don't overpay just because its a turnkey STR or you think it will make more money than projected), and look into ways to increase bookings during those slow months with some marketing and operation tweaks. 

I also like the strategies outlined in Brandon Turner's "Rental Property Investing" book.
