It was well under market value as it was in rough shape, and I only negotiated a concession for the clean out from the hoarders.

Make it clear that if the house is left in good shape they will get their deposit back (but if it's in bad shape or rent is due that will be deducted). 

The bones of the building were in good shape since all of the plumbing and electrical was up to date.

Each of those factors directly or indirectly impacts the behavior of the housing market.Other factors include individual readiness, the location of the home, and ongoing housing trends, including interest rates.Despite the external shocks to the housing market, seasons remain a major driving factor in when to buy a home.

I dont think Grant Cardone is right, but I think the trend is towards a rental society and that we should expect that the future will have more renters than owner occupant 

., etc.Depending on these types of factors, what makes sense for one person might not make sense for another person...for instance, a person who has a net worth of $10k, and who has $10k of credit card debt is probably over-leveraged...but a person with a net worth of $1 mil who has $10k of credit card debt is probably in OK shape (I say "probably" because there could be other factors in these peoples' finances that could change our assumptions--for instance, if the millionaire had $5 million in auto loans for exotic sports cars, they might be in trouble).Context is everything.

The trend toward flat roofs is just silly in most areas (bc it causes water diversion problems, which then cause a myriad of other problems).

Doing some searching, my pool is a bean shape.

Your booms & busts will be closely tied to macroeconomic trends that are beyond your control.
