I am surprised these lending institutions don't regularly run algorithms showing which loans have been assumed Seems like an relatively easy thing to do to regulate and in a way minimize risk - maybe have more defaults but still maximize their loans by forcing compliance 

There is also algorithm advantageous to bi-weekly vs monthly, so a bit of a credit-hack boost effect to it. 

Indeed, the zEstimates are quite imprecise; its algorithm is a mystery.

Yeah, they have algorithms and search tools that scan your messages.

Maybe "a friend" used your computer and impacted the algorithm...

Motivated sellers aren't identified by an algorithm.

The person who gave me a demonstration mentioned that by using it, listings were much better ranked on Airbnb (he emphasized that the listing updates every night, which is good for the algorithm).

I am also a real estate professional and I use DIY cost seg to do algorithm based cost seg studies.

Different platforms use varying data sources, algorithms, and criteria for comps, so discrepancies are common.
