Whatever you buy, do it with a margin of safety (reasonable discount to market value) to ensure that you can weather some storms.

Talk to Los Angeles Building And Safety Department.

Tenants move out for the same reason.A property manager is there to oversee the safety of the building.

Some of this is foreign money that is being parked here -not for appreciation but merely for safety. 

So legally couldn't spend the money anyway, so I've got a safety there lol.

However, for most of us, we don't have staff manning the address and you definitely don't want to put your home address either for privacy and safety reasons..

There is enough risk and more than enough moving pieces in real estate as it is, no need to compound the risk by not having a safety net and buying with high interest debt.

Occam's Razor suggests it will be the latter.

I have a code enforcement inspection each year and the biggest issue is usually smoke detectors and any other safety violations.

My theory is to follow Warren Buffet, who preaches to make money when you buy the asset, have the financial wherewithal to hold on to it forever if you could and always keep a margin of safety.
