Lastly, understand that for whatever reason, the Youtube algorithm doesn't love real estate.

I'm assuming they use some kind of mass marketing in combination with an algorithm to determine which properties to buy and how much to pay for them.

The market is part of it, but even within the same market you'll see huge variation from host to host.My experience has been that VRBO's algorithm is EXTREMELY momentum driven compared to Airbnb's. 

FB obviously has some algorithm to determine this isn't a legit personal profile. 2.

If you submit your offer the day or two before, it may hit the algorithm just right and you will have the jump on everyone else.  

So apparently Google changed their search algorithm yesterday in an effort to curb content farms, decrease the scoring for lower-ranked sites, etc.

Therefore, it is impossible to tell exactly how different actions will affect your score, unless you have somebody on the inside of the credit bureau who can deliver the up to date algorithms.

Since nothing is the same, a new valuation must be done every time and a computer algorithm wont be accurate. 

I do think these algorithms will get better over time, and that appraisers and agents can choose good or bad comps and skew an appraisal or BPO.

- Should I use tools like airdna and mashvisor to try to surface properties with good cash-on-cash potential according to their algorithms, and then bring those deals to her to compare them to her on-the-ground expertise?
