You can get all sold data from county or propstream but it won't have "sold for" price.

The mechanics of how it's calculated are too complex to explain.

Here's the AirBnb listing, https://www.airbnb.com/rooms/3... and the complex website, https://www.harbourvillagefl.c.... 

Residential leases are far less complex than commercial leases, and most of the time, depending on how long seller has owned the asset, all leases will be uniform with the exception of lease start, end, rent and unit.

Can anyone tell me how accurate the crime data maps are?

OneSite really shines with the data analytics.

What do I do if the Buyer Estimate from a real estate agent does not have matching data to BP tool calculations?

Looking at the free data on AirDNA, it shows a 74% occupancy rate for the entire town but I don't know if that translates to this particular property.   

Or you can become an agent yourself and get the data yourself although becoming an agent does require a fair amount of time and money.

Sometimes Zillow or even the MLS will bring in public records data, and will show houses as have 1.5 baths or 2.5, etc.
