A question about the 70% rule for analysis, and real time use

[Jim Noseworthy]

Good morning all. New comer to the group and first post. As an investor that is just starting out, I am in the education process. I’ve been reading about assessing property values and utilizing the 70% rule. Can anyone share their experiences where using the 70% rule has elicited a deal, or have you had to use a “+/-“ approach (with a little bit of gut feeling) to determine an opportunity? Hopefully this question makes some sense. I look forward to your responses
