Also, I have a rule that says only registered guests allowed at the Airbnb without approval from the host.

If you haven't found it yet, we host a networking meeting nearby on the second Monday of each month.

Who hosts that investor lunch?

@Darren Sager hosts great meetups (complete with industry leading guest speakers) in Manhattan.

However, last night I had attended webinar hosted by Brandon Turner where he walked us through an analysis of a rental property.

The difference is that there's a professional salesperson (real estate agent) hosting the appraisal who in no small part justifies real estate values for a living (to clients, to appraisers, etc etc), versus a consumer on a refi just opening the door and saying "yup come on in, I'll be in the other room if you need me."

It's simply not worth the issues you will face as an investor from a whole host of restrictions in place and now being more strictly enforced. 

If i'm not wrong, our Host, Brandon Turner has weekly webinars, I think it is a very good place to start.
