This is not the only thing that plays into their ranking algorithms they take into account online bookablity, instant quotes, conversion rates, response scores, reviews, ad level, calendar update time etc--you can buy a promo to help you start collecting reviews even price a little lower to get your first few. 

We found that with a little tweaking, our algorithm could also find emerging or declining areas of residential real estate.

I asked about sending over financial docs and they said they have a algorithm and that be doing so is not needed.

I've integrated automation for messaging and dynamic pricing, and taken all the necessary steps (that I'm aware of) to align with AirBnB's algorithm - Instant Book, flexible stay minimum and cancelation policy, building up 5 star reviews etc.

It is important to note that FICO has many scoring algorithms and the score from say your credit card is a different algoritihim that the lenders use.

They use an algorithm and cross reference lists with other lists where the seller is more motivated. it's a shipwrecked list as they call it.

@Matt Grubb I have found the algorithm to be somewhat unreliable depending on the area.

If you are however not using reality to value properties, and instead think some algorithm or formula is the way to value properties...well dont do that. 

I dont know how their algorithm works.

Each has their own algorithm.
