MY SOURCES:SHORT VERSION ON CHINA:Information out of China on the CoronaVirus Can't be Trusted, so there is a huge amount of unknowns.

We buy properties in a land trust.

Get the cap rate from a trusted commercial realtor in your area. 

You'll need something deeply important to you to help push you through the challenges, because, trust me, they will come.

Assuming you have something written into section 6 of the RTA standard lease agreement about this expectation, I am guessing you would be able to hold up on handing over keys until this is done, but check it with a paralegal or trusted PM to be sure.

Curious as to what type of trust you are envisioning here? 

I would train them on a few of them before I can trust them to do it on their own. 

But even so, there's still risk and uncertainty.My question is:1) How do you get over the mental hurdle of trusting someone else will do a good job without you being there in person?

My recommendation would be to have a Realtor that you trust run some comps for you and provide you with a net sheet.

They are not professional so they are trusting you to look out for them.
