Id start with ringing the bell instead of knocking.

I would think 2" should be enough.  1x2 with drywall and extension rings on your outlets. 

However, less thought about individuals range from advertising agencies to commercial printers, Web hosting companies to wedding planners.

So many times I would tour a home with a client at 8:30am, go to the office and do some prospecting, meet with my team over lunch, research new listings and follow up on phone calls all afternoon, then go home only to have the phone ring during dinner because an offer was coming in at 8:00pm, so race back to the office or property and negotiate a deal, which may or may not close!

Did you try Groups, where each group has a unique ring tone and you assign contacts to one or more groups?

I'm completely new to investing, but I know I am made to hop in this ring.

Here's another article about the January 2016 sales in Memphis.For what it's worth, I just spent the day (Wed 2/10/16) driving around town looking at Class A and B properties with a CA hedge fund and was shocked by the lack of available inventory for sale.

If you just want the phone to ring be more open. 

Hello,I watched Brandon's webinar on Wed.

I have been working with some Atlanta rental property owners (with units in prime ATL locations) who have been looking for an experienced professional Airbnb rental manager to take over the management (they are looking to transition units from long-term to short-term rentals).If this is something that you think you might be able to help them out with, send me a message or give me a ring, and I would be happy to see if I might be able to get you in touch with the owners.
