Mine is customized to my properties and my needs.I have a tab for each property.

Additionally, I’ve been wondering if it might be possible to create an LLC, rent my house to the LLC through a formal contract, and then have the LLC operate the Airbnb.

One thing to keep in mind is that in some markets, including mine, you cannot segregate against Section 8 renters. 

In the next 5 years, we can buy one property per year with 25% down (~100K), and perform the same operation of using cash-flow for paying off properties next 15 years and we will have $15K/month net-profit which hits our goal adjusted for inflation (assumed at 3%).

@Tanya MaslachYou do not necessarily need to have an Ohio based entity to purchase and operate rentals in Ohio, HOWEVER, many lenders are beginning to require that either an entity based in the same state or a foreign entity is registered in that state in order to obtain a loan approval. 

Will share a similar update on mine when under contract. 

Their book is super helpful, and so far I'm guilty of at least half of all the newbie mistakes they talk about, so I expect my rental operation to improve as I implement their advice over the course of next lease term.

And when people get tunnel vision for lowest $ down, they tend to not give attention to the revenue generation of it, the operations, and that's a VERY dangerous combination of high leverage and not so-good revenue. 

Operations- how will operations be performed4.

Turnkey is generally a passive investment strategy, where you just buy from an operator and turn it over to them to manage.
