STR revenue projection questions

[Michael Steimle]

Hello BP! I am a general contractor that is beginning to investigate income generating property investment. I have no issues analyzing long term rental deals because it straightforward to forecast stable rental income. However I am struggling to find STR income data that I can trust when making decisions related to purchases in the millions of dollars. Is AirDNA reliable? Do they provide any type of guarantee on the accuracy of historical data? Is there an independent data clearinghouse out there somewhere? TIA
