And if a buyer gets "cold feet" as was said, they need to use that as motivation and then find a valid reason to get out of the agreement, but "cold feet" as far as I understand the law as a layman, is not going to be sufficient. 

Im just thinking about, in the event I want to move out / purchase the next property, how much I may be paying out each month to hold on for potential/eventual payoff when I sell.And how long would it take for sufficient appreciation for a decent return? 

Rul. 8429039, provided that a two-year holding period is sufficient to ensure treatment as a tax-free exchange (all other tests being met). 

This sounds like the price is too high or they have found a better deals after closer look.It really depends on many factors, like what is the exact location, what is the shape of the lot, how is subdivided,  how is it accessed, how far are the closes utilities, are those private / public, is there any public access, are the access sufficient or do you have to build a new roads etc. 

Mainly to make sure that I can sleep at night knowing that im providing value to people and to build a network of investors that are willing to work with me on future projects as well.

I mean, seriously, if you get married at least have the decency to keep it in your pants for two years before you start sleeping a coworker, right?

If someone were caught drug dealing in 2010 but finished their sentence in 2012, that would give them six years of history to prove they had changed their ways, which should be sufficient for any Landlord.In your case, the guy was honest and admitted his mistake.

Seems to me in general people are working and have a family, sleeping, eating, cleaning, maintaining a pet and a car is all a major % of their time, they don't or can't or won't spend the time needed to be expert/comfortable enough to participate in and be good at stock investing for example. 

@Joe Villeneuve words of wisdom indeed - couldn’t sleep after reading your comments :)Will be in touch for sure

I don't know that I personally would attempt this action though, but as long as you can sleep at night.
