Hi Richard, I am a Certified International Property Specialist who works with a network of the same "globally focused real estate agents"  this group would likely have all the resources and information you might need.  

This seems like a terrible idea, no offense but if you have no clue where to start you're likely going to have a bad time with a flip.

The neighbor tried to sell it to a wholesaler who made a super low-ball offer which she found offensive.   

It’s just good to be aware of the laws as in some states the first offense is a misdemeanor and the second is a felony.  

To deny climate change outright is foolish.However, the degree of change is so minuscule that it would never be noticed in several lifetimes.Do not be surprised if 10 years from now the media will tout warnings of a global ice age.Just look at history:https://anhonestclimatedebate.wordpress.com/2009/08/02/climate-change-alarmism-timelin/

High end black and grey work nothing trashy/offensive. 

I plan to travel globally on a regular basis, but I went to Stanford, I work on AR/VR in the Bay Area, and my family operates a meat farm in Vacaville.

That's the first line of offense against sound.

For example, If The seller is asking $37,500 for a 2bed 2bath but you found a 3bed 2bath In the same neighborhood, same upgrades, same features, etc that sold for only $38k, then you have every right to convince them their home isn’t worth $37,500 because your home is missing an entire bedroom and it’s not nearly as upgraded, etc. as the 3bed 2bath home.But, this is a dance so you don’t want to offensive to the sellers if you really do want the property. 

Another unknown is what will Global Warming do to prices?
