Another way to think about this is that this is how you become a slum lord/ B class neighborhoods decline to D class neighborhoods.

Decline that request.Tell them "I'm not comfortable with this guest staying in my house but more importantly I want to cancel due to the rules violation.

Do banks decline a lot of people who are not established in the industry?

Travel nurses still make a good income but declining rates will affect what travel nurses are able to afford currently and in the future. 

They started declining renewals on units this spring. 

In the last week I've spent *hours* on the phone trying to deal with multiple scam bookings, invalid and declined credit cards, and unearned commissions.

My pleasure and yes, Phoenix is a magical place ;-) Imagine though, we evaluated dozens of properties ranging from 11 to 562 units, made offers, most declined, some accepted and ran two on due diligence - none of them panned out.

To be clear, you can get sued and E&O may still decline coverage.

Many landlords during each of these eras experienced a 25%, or more, loss of gross rents.I can't predict the future, but our next major decline could be due to overbuilding of apartments, a continued trend of cost of living exceeding wage increases, a fracking industry that suddenly gets legislated out of existence, institutional owners of single family portfolios suddenly choosing to liquidate their holdings or even, as you'd said, governmental intervention in the form of rent control. 

Because while neighborhoods decline, sometimes it's not forever.
