Getting an offer in right before a price drop sometimes helps take some psychological pressure off the Seller: they're already emotionally prepped by their agent (if their agent is doing his/her job) that a price drop is coming in a couple of days. 

Like those that buy an underperforming business and turn it around.To Darius’ point, assuming we can even assume the financing, I know in one sense, they are not completely free of that financing for a while till we could sell it, but perhaps it would be psychologically freeing that they don’t have to worry about managing it from across the country.Question, what would be another solution?

I read every book about personality, psychology, selling etc.

But, there's lots of offline data:  The psychological state of the seller, the intent of the seller, unlisted properties, unlisted property details, etc...2.  

I feel a profound psychological peace in owning my own home.

If I didn't make the real estate investment move mentioned herein, psychologically, I would have felt forever imprisoned - chipping away for 10 years or more.  

Anger management issues, psychological problems, drug abuse, criminal behaviors, etc. are more prevalent in those areas.

Which between psychology, economy or finance would benefit the most my career as a real estate investor? 

In townhomes we get the guiding psychology from it being a community, with community rules.

Just to boil things down, I tend to look at multi-family from the standpoint of mass psychology, plus the relative nature of different markets.
