I'm looking for some information / guidance on cold calling.

To me, that makes a lot more sense than cold-calling someone.

For me, I knew I wanted to work on building out a listing business for luxury homes so I got to work cold calling luxury home owners and building my brand as a luxury agent.

There are no add-on fees (you pay the same if you came in cold, or if you got referred), their fees stay the same for everyone no matter what, and they are very honest.  

I looked into those markets for my group but unless you yourself can grind out your own wholesale deals meaning you run the skip tracing, you develop a list, and you cold call in hopes of getting a house under contract. 

You can also cold call them as well.I'll also point out that there are sometimes great deals on-market.

Not sure how cold is gets at night but lots of investors here in various report improved winter bookings when they have a hot tub. 

You also get the skiing traffic in the cold season (when it used to snow here).

If all you are looking for is motivated seller leads, I would recommend not using an agent and building another pipeline via direct mail, cold calling, ect.

A big one is cold calling but things like mailers, door knocking, mass emails any sort of direct response marketing is great to find actual deals.
