There was a party on too many people got on the deck and it collapsed, I think a couple died and several injured.

When the dotcom bubble collapsed in 2000, did California real estate prices crash along with it? 

cracked or collapsing pipes can cause items that would normally drain to get stuck.  

I've had concrete two story stairs collapse; a full room plaster and lath ceiling fell due to slow roof leak, narrowly missing occupants; kitchen waste line main was blocked, several floors above were draining out of our kitchen sink...in a million dollar plus 2 bedroom condo...for a couple of days, as the people below were out of town also so there was nothing reported; I've had Tenants on a few occasions walk out the door leaving EVERYTHING behind; a well known Bail bondsman vacated a property that had apparently let multiple pit bulls live and crap throughout the multi-million dollar house; Military Tenant who was separated from wife, but she came to visit, they fought, SHE got a TRO against him, and of course she had no income and paid no rent for the several months it took to evict; Another Tenant, quite elderly, lived in a walk up and had two yappy little dogs.

Sure, but it will be unstable and collapse.

Happily I got a pretty good property on which they did a good renovation job, and just before they went belly up I kind of smelled a rat and got the house out of their management, so their collapse didn’t affect me.  

Things have changed so much since the housing collapse.

The assessment probably has a lot to do with people wanting to sell, but I know a lot of the updating is foundational problems and after the condo collapse in south FL people are pretty leery of older condo buildings. 

So, a roof collapses on a tenant they sue me and my hazard and house.

I found out that right after closing they found out there was a collapse in the pipes and had to re-pipe the entire house.
