A mirror held up to see yourself without seeing yourself physically.

Before spending six months, third party costs, wiring investor money...perform the physical inspection.

Otherwise it could be thrown out and notice would have to be served again.This is good to know, and I looked it up and it seems like in CA it's expected to be handed in person or hung on the door - but what do I do besides send an email if I've never physically met her and she doesn't live there?

Quote from @Timothy Dunn: I would love to know the physical home address as well.

This gives you boots on the ground who can physically walk the property, verify rent rolls, review comps, and protect your investment—not just at purchase, but long-term.

It’s still a good idea to have someone check the home’s physical mailbox periodically to clear out junk mail or catch anything that slips through.

I am a husband, soon to be new father, and work as a physical therapist in my day job.

A property profile is a physical description of what and where the target tenants rented.We bought similar properties, over 580 to date.
