For older rentals this is something I would love to have a plan for, should the water ever stop draining due to a blockage/break/collapse  (or worse- a backup into the house) of an old underground main sewer line. 

Short of catastrophe - i.e. the economy collapses so hard that people are living under the bridge rather than paying for a rental because they can't - you are always going to find people that would rather live in a house than live in a cardboard box. 

It has been observed across the nation in the last 30-50 years that most injuries and deaths caused by earthquakes are caused by things falling on people (not structural collapse).

I think an underreported issue is that the prime first time homeowner demographic are 'children of the housing collapse', who grew up watching their parents and friend's parents lose their homes or be stuck with negative equity.

For the first 3 years after the great collapse all the turn key guys went to promoting IRA buyers.. all cash 60 % of all houses are bought with cash..

Unless the wall is literally on the verge of collapse, you should be able to stabilize it with an engineered solution and a lifetime transferrable warranty against further movement.

I find it so ironic that the majority of us are experiencing varying degrees of this good tenant fortunes, yet many are posting of "Housing Market Collapse" and speaking of how doom is happening, the end is near, blah blah blah.

If it collapsed like that condo building in Florida, or the fire in California, would they cover you, against the claims from the tenants and their survivors?
