My intuition tells me that the 16 rule will skew AirBnBs pricing algorithm and have some negative effect on search results and display ranking of the largest properties.Huge custom mansions (20 person plus) with a traditionally high minimum nightly rate will now be at a big disadvantage in search results against a true 16 person sleeper (mid size) which has considerably lower minimum rates.The largest properties are now in direct competition with mid size properties as far as sleeping capacity and as a result I expect AirBnBs algorithms will begin to ease prices down on the largest STRs because the mid size STRs will always appear as a much much better value.If my assumptions are correct then what follows is basic economics. 

They run an algorithm based on sales.  

Which is why people probably like ZIllow since I'm sure their algorithm is just raw number-crunching to get an average.  

If you are specifically looking for off market, yes your agent can filter by many different criteria...type off ownership, years owned, amount of equity, loan balance, out of state or in state owner, even ‘likely to sell’ based on algorithms and many others. 

Even Zillow has acknowledged their algorithm is bad, that's why they offered $1M to anyone to come up with a better valuation tool to help them out.

I don't know exactly how the algorithms treat 4/5 star reviews on the OTLs but for me in general...a 5 star experience means an 'exceptional' experience. 

In fact they almost never do, as central bank intervention, stock buybacks, an increase of passive investors, high frequency trading/algorithms, interest rate manipulation, quantitative easing, government stimulus spending etc. have been saving the global financial system from falling off a cliff, while befuddling bears and short sellers, for several years leading up to COVID 19. 

I am great at data analysis and software/algorithm development so if you need to automate or calculate anything I'm your man.

They did nothing with it and the site ranked high but had no content or value.Yahoo and Bing haven't changed their algorithms lately but Google has.Yahoo internet search volume is about 12% and Bing is at 18% and Google is in the very high 60's.

Just changing your search algorithm to require two upper-case letter abbreviations will help eliminate (or reduce) some of the problems.
