If they refuse spit in their coffee when they are not watching and take a picture of that green brown yellow loogie floating in their coffee, and when they finished drinking it, ask for their number, then run away and once you are in your car send them a pic (or video even better) of that monster loogie and them drinking and chewing on that fat slimy loogie and then say in the text, if you only had given me their info.

Find Brandon's videos on YouTube for the "four square" method of analyzing homes and practice.

It's a mix of on demand videos, live Q&A sessions, and a step-by-step curriculum to help you get your first deal.
