As with any model the motto "garbage-in, garbage-out" stands, so more detail often means harder to use and less accurate.

The comps of actual listings and how much they generate is way more accurate in my experience

I will start with what I know, someone of which may not be accurate but still trying to figure this out.1.

I bought a non performing note, the borrower sold the property sub-2 where the new buyer reinstated the loan but because of the transfer I am calling the due on sale clause.

Rare is it the builder's rep will accurately explain to buyers how the property taxes work. 

Pay for performance.  1st one is always at full price, if you want to discount a bit on future deals is your decision depending perhaps on the volume and the amount of work required. 

I don't think it is that accurate sometimes, but combined with the review on the 2 OTA's, you should get a pretty good idea.You can also go to Awning.com's estimator - https://www.awning.com/airbnb-estimatorIt is free and pulls the same basic data AirDNA does.

And you won't find more accurate or complete data.  

You can delete trips that were not made in the subject vehicle, so your percentages are accurate .  

Go talk to the the current PM....ask them about property performance, asked about rent bumps on upgraded units, ask about the competition and go visit.
