Best practices to determine accurate home value when working leads ?

[Westin Hudnall]

I need some saavy investors to give me a few outside the box strategies for obtaining accurate home values when working property leads. I have MLS access but don't trust my judgments. Actual appraisals are too costly if you are working multiple leads per month (both financially and time wise) and as we all know ; judging a value wrong can kill a deal and hault business growth in its tracks.
