How Accurate is free version of AirDNA?

[April L.]

I'm a newbie investor in North Georgia mountains and Western NC. I use the free version of AirDNA as my primary tool for estimating rental potential. However, sometimes, I'm really surprised at the results. It spits out either very disappointing numbers in areas I think would be popular, and in some cases, spits out high numbers in areas I don't think would be successful at all. Also, I notice that I don't always get the same result when I plug in the same address on a different day. 

How much faith should I put into this free tool?

What @John Underwood said. AirDna is pretty worthless even with their paid tools. Why let an algorithm give you guesstimate numbers when you can get the real ones yourself?
