You want to stay away from the large lenders like WF that send their docs off to an underwriter in another state to run algorithms.

Our software application works on connecting sellers, buyers, renters and involves yield generation through advanced financial algorithms. 

I spoke with the founder of AirDNA and he said Revenue potential uses a complicated algorithm that says "what days were available, how many days was it booked, how many days was it unavailable, how much does it make compared to comps, and what would it bring it if it was available for the days the property was blocked." 

You can use facebook's algorithms to find like audiences that have similar behaviours and characteristics to those that have previously shown to be motivated, but as you can see... this is not at all what you were asking about right?

If they are the ones making the offers they are incentivized to tweak their Zestimate algorithms to produce lower numbers.I realize Zestimates are not always accurate or a good measure of home value, but there are many people out there that put a lot of stock in them.Would you hire a home appraiser that made cash offers on every home he or she appraised?

Don't forget that the vast majority of purchases are still to retail buyers so how the property looks is a HUGE deal and something an algorithm can't quite calculate. 

I spoke with the owner and we chatted about the algorithm.

Has to be something in an algorithm somewhere in the programming :)

FHLMC treats their exact algorithms as a trade secret. 

Those estimates are algorithms of comps, but they might aggregate anything 1-2 miles away.
