Is Cold Calling Tax Delinquents an Efficient Use of Your Time?

[Erik A.]

I recently whipped out the credit card and bought a list of 750 Tax Delinquent properties in my county 

and a few surrounding ones -followed by Skip Tracing them. Many of the numbers I've contacted at this 

point are either the "wrong number", not interested in selling, or the occupant straight up curses me out.

Now, I think one key trait separating the winners from the losers in this business is sheer Iron Will. So,

I do not mind going through the wringer. However, is cold calling Tax Delinquent leads an efficient

use of one's time, or would you just send them direct mail? 

Also, my intro when starting each call is something along the lines of this: 

"Hi John, my name's Erik. I'm a local real estate investor interested in purchasing the property at

 789 Live Oak Dr. I'd like to have a quick conversation about it if you have a few minutes."

I never mention they're tax delinquent.

And while we're on the subject, which leads list would you recommend calling? (Probate, 

Pre-Foreclosure, etc.)

Thank you all
