Yellow Letter List

[Danny Weber]

Hello BP! I haven't posted in a while because I've been caught up with work, school, and building a start company for real estate. I have a quick question about Yellow Letters. I used a list preivously based off of the pod cast of the Co-Founder of Yellow letters to make sure every person you mail to has greater than 40% Equity in each home. What are other parameters that I should filter my list to so I dive deeper to find those hidden gems? Any suggestions on how I should recreate my list and also what type of letters should I mail, Postcards or yellow letters? Thank you for taking the time to read this and I hope to hear from you all soon!
