Wow, like drinking from a fire hose. :-)  I have a 1031 client looking for replacement options. 

It's going to be awful boring spending them all drinking Appletinis. 3.

You have a tenant living fulltime in a unit and likely is leaving their belongings in the unit while you occupy it.

At the same time, look to see if he left any contact information behind and reach out to family to determine his status.If you can't contact anyone soon, I would consider moving his belongings to storage, terminating the lease, and finding a new roommate.Because you are in California, I would consult an attorney.

If too many people are ignoring the data, why wouldn't you be quiet about it and pay attention to it yourself, and become insanely rich from it- and sit back on your private island and laugh at all the fools who ignored it while you drink Pena Coladas From a deck chair in the sand???

In short, getting the place restored was akin to remediating damage from a natural disaster.In the trash and belongings abandoned by the tenant, he also left the OM for his healthcare real estate endeavor, nasty-grams from the IRS about his personal taxes, and collections letters from several creditors after him.I got burned here and so did my property manager.

There is too much risk of damaging their belongings and work will be slower as people are working around things.

What MLS and board does your broker belong to? 

I am learning by drinking from a firehose. 

For the lease you can cancel if a unit in not habitable and your tenants renters insurance should cover their belongings.
