(I believe this to be an analytics fail as I found this community through word of mouth and one I checked out the website, then these posts about MI shot to the top of the search - just an interesting aside.)

My question is: what would be some impactful pieces of automation or analytics in the investment space?

Some might consider that gambling, but I call it being analytical.

Say initial investment was 30k, can you add the hidden 2500$ saved in taxes to whatever the income earned on the property was to find the ROI for analytical purposes?

Closing on 151 units in that period of time is impressive.Forgive me, but the analytical side of my brain can't quite accept your magnitude of success.

You seem like you are a very analytical person and are big on numbers, which is great because they are very important.

In fact not one person has complained to me about extra fees.Homeaway now has awesome analytic tools, graphs and charts that are superior to anything you have to pay for on airdna.

I see people making this analytical error all the time on this site: asking what they should pay for an asset "in this market," as if the only thing that matters is buying an asset, regardless of where we are in the cycle or whether they will make money at that price.Real estate does NOT always appreciate, not even in New York.  

The goal is to use the information in the classroom and work on building useful analytics from sources with different formats and levels of detail.

I compute valuation metrics for various states/counties in my data analytics LLC, as well as for multifamily investment out of state.As of Q1 2020 data it looks as follows: while Washington state is among just 8 overvalued states nationwide (>10% overvalued based on deviation from historical price-income relationship), King County (Seattle-containing) was the least overvalued at ~2% valuation.
