Lot going on here so I would try to slow things down a bit and take smaller bites of the apple. 

@Chris Heinmiller you can export a list of recent (i.e. 18 months) land trades from Redfin, but you do have to separate the apples from the orange and the bananas, but in an area that is somewhat homogenous, you'll usually be able to see a trend, i.e. you might have two low ones at 20-30k per lot, and one or two high ones at 175k-200k/lot, but then you'll see six or seven trades in the 55-65k range, and then you've figured it out. 

Clackamas county (slightly less expensive) or Washington county (intel,Nike,Apple,Microsoft) these tech companies have increased the cost of living and house prices  (it’s higher than downtown pdx) but the neighborhoods are good and safe. 

Under Reason for Amendment it says, "300 Apple Street is located on a residential street primarily consisting of single-story detached dwellings zoned TN-E (Traditional Neighborhood Existing).

Pretty soon here I plan to get a QR code to the direct booking site for my listings and put them on a fridge magnet or coffee mug. 

Eric I think we have touched on this before on appreciation.we do need to compare apples to apples.. 

HOWEVER, there's a great demand from travelers and tourists who need a place to stay in the Big Apple.

Compare apples at the net bottom line number.

Tesla is building their new semi-truck factory next to their battery factory, Microsoft, Apple and Google are investing millions into data centers.

That said, they all bought a few years ago at least so looking at their cash flow is not an apples to apples comparison if you're buying at today's prices.
