What are some good tips to get the conversation rolling during a cold call?

You will network with people who offer tips on refinancing, good books, effective classes, ect.

Any beginner tips would be much appreciated.Have a blessed day :)  

I'm curious as to any tips you may have to finding the best rates/loans available.

I have quite a few apps that I've built for wholesaling that may be of help to you.
