I figure I’m having a midlife crisis or making a smart move but you only live once so I’m ok trying this! 

The ordinance passed is basically "turning a blind eye" while the housing market is in a state of crisis.

A HELOC on your residence can be a useful tool in real estate but I would certainly be cautious about using that up since that is what could keep your head above water in a financial crisis in either your personal or REI lives.Play out some "what if" scenarios. ie, What if someone loses their job?

I wasn't involved during the last crisis, what is to be considered when using a BRRRR model?

I have seen some folks post on BP that credit unions didn’t call in HELOCs in the last crisis, but I did not have one in the last bust, so can’t comment from personal experience. 

I would suggest that the second floor tenant approach the first floor tenant and diplomatically address their concern. 

Everything is Just In Time, with low inventories.The economic impact may be similar to what happened in the Asian Financial Crisis of 1997, plus a bit of SARS from 2003, in a US Presidential Election Year!

When investment strategy has only been tested in bull markets, we really don’t know how the same will hold up in crisis situations.

Capital controls imposed on Chinese citizens really began around 2016, which may explain why homes prices really started jumping up early 2017 as the controls became effective around June-July of 2017 so presumably many buyers were rushing into safe haven assets in anticipation of this happening.Long story short on China, many citizens have fears of policies over there and feel that a weakening Yuan over the next several years in addition to bank runs and an impending credit crisis (China has printed more money over last 2 years than ever in their history) will have heavy implications on their wealth and they wish to diversify and send as much money out as they can before things begin to get really messy.

"The city is in crisis … with respect to housing and affordability."
