I believe the newer ones are supposed to have drainage pans to address damage like this.

@Jonathan Styer is correct - simply having proper drainage prevents most of the issues. 

You plug it in to your computer's USB port and it heats up a surface where you set your coffee mug to keep your coffee warm.  

This barely scratches the surface, but hopefully it puts you on the right track.

But just because I think investing locally is better for me does mean I think it's better for everyone else here that lives in So Cal.I think part of the problem is that folks look at listings here locally and then look at listings provided by OOS turnkey providers and automatically see that on the surface, the proforma CoC is much higher OOS. 

The first property I bought had extensive deferred maintenance, which I knew going in and budgeted for, but did not budget for the extent of what could not be seen (poor drainage causing water intrusion during heavy storms, termite infestation after I bought the property that cost $2k to treat, ongoing A/C maintenance due to older systems, etc.)Knowing what I know now, I would factor up my repair budget and expect things to come up over the first few years after purchasing a house that was vacant or poorly maintained before.

I don't expect problems here.Plumbing--Also don't expect problems here.Elevator--No experience, so will get this checked.Landscape/irrigation/parking ingress/egress issuesGlass and exterior facadesAll interior surfaces and fixturesSecurity issuesInternet/phone access Examine all suites, common areas, and service areas, all I can see, smell, touch, etc.Anything else on physical due diligence?

Might be a value add in the rehab when the jobs surface.

Gas is preferred for the surface burners, by most cooks, while electric is generally preferred for the oven.  

Paint is cheap and covers the most surface area.
