Florida has a housing crisis with a lack of inventory and we're in high tourist season right now - yet that market has 88 unrented units.

Speculation aside, I'm not only concerned about another crisis.

I have lived in 4 countries and have learned that politicians love crisis or war to infringe and steal whether you're in east or west.  

2.9%...1.9% during the housing crisis (worst thing ever to happen to real estate). 

The rent/price ratio was a rule of thumb created after the housing crisis as a way to compare the surface level of multiple deals.

The concept of a zero day in this context is that with every challenge, every setback, every crisis, every time there is a vulnerability in the system, there is a dip in performance, the system goes offline as the architect of the system attempts to resolve the weakness.

@Andrew Erickson Right now the ADU rules are being relaxed all over California in order to help solve the lack of housing crisis. there are a number of contractors who are specializing in helping home owners put small units in their back yards.

I have a brother in that area, and after the housing crisis, there were tons of cheap houses.  

Having been unable to get a satisfying price for it, I just got it rented and will be able to reserve about $500/month after PITI payments on the note (it's a small single fam worth about 230k with 125k debt on it)I am now licensed as a real estate agent and working with Keller Williams in Boston, I've spent the intervening time to analyze at least 200 maybe more small multifamily (3-4 family) deals in Worcester (I have actual cashflow calculations with reserves usually around 35-40% after debt service for around 50 of them).In response to the current crisis, I've purchased software and a camera to create 3D tours and video walkthroughs which I'm using to serve other agents and investors, and I've done about 12 3D-tours so far with 7 more lined up for the week.I'm also in the process of learning some proven strategies others use to find off-market deals and working with another agent/wholesaler to help grow his business and my own.I am actively looking to find more investors to work with to source deals for them, learn their criteria and add as much value as possible.My chief personal goal for the year is to purchase my first house-hack likely via a seller financing deal by the end of summer so that I never pay rent again after August 31st.

In addition to eliminating a single point of failure crisis for your business, you'll get the back end analytics and get to know your guests.
