For example, one property had a collapsing sewer line.

The distance did not stop an apartment building’s wall in my neighborhood from collapsing.

What a long post...I am in Macae, Rio de Janeiro, Brazil for the first time in 9 years after the 2008 Collapse of the US Economy, Hep C and the new cure, almost dying from the tumor on my liver that showed up four years later and was not discovered by all my Primary Physicians, my Oncologist sitting on my bed when they were pulling the tubes out of my throat to see if I was waking up as a vegetable...the only thing she said was, "you need to get your affairs in order...you have three years to live."

Years ago before the economy collapsed, we used to fix and flip homes.

thinking the collapse would not hit Arizona where there is a shortage of land.

I can't imagine what the impact on my life would be if I designed something that collapsed.....it would hardly make up for the measly salary I was collecting at the time.  

The sewage work came to $3000 (the catch basin had collapsed and plumbers thought it should be removed, dug to standard 5 feet depth, and replaced).Also, the other CHA inspection issues required repainting both units, along with some fixes that had been observed during the due diligence property inspection.  

In 2008 we had the Economic Collapse and anyone who did not own their Rentals outright or had saved a lot for the downtrends, lost all or most of what they had.

The tenants also left behind a: collapsed garage, 2 sheds, collapsed pool, and some structures for holding dogs outside (we removed all).

It would be unwise to think the economy will remain strong while almost every credible leading economist has been shouting as loud as they can that we are on the edge of a pending economic collapse.
