But joining a good Mentor and Networking group can be advantageous if you are missing any of the needed components. 

I am sure some will do it with phone and e mail etc.. but I suspect they miss the best deals.Just like top wholesalers they have buying agents when a lead comes in that buying agent is over to the house and meeting with the folks ASAP so they can lock it up.. if they are non owner occ then yes this is different but now your talking about investors as sellers different mind set .  

It kills 2 birds with 1 stone in the sense that it offers me evidence that the property is cleaned and everything is in place before guests arrive and watching video after guest departs helps me make sure everything is there, and nothing is missing / damaged from last group.

Another question is… Which option would be better to cover the missing mortgage payments: a HELOC or forbearance?

You forgot to say, or I missed it, how much you paid for the property.

It sounds like you are missing a conversation with the tenant to understand the situation.

The only thing that I see missing if they are purchasing with hard money debt they may want to factor in 3% - 5% for closing costs (points, fees, title, etc) Thx Zachary!

Overall, I've lost confidence that he is doing a good job and wonder what else he has missed if I was able to catch the mistakes. 

Missed opportunities.

Because in vast majority of cases these same tenant applicants a few missed paychecks away from bankruptcy; are working only 1 job.
