Does anyone have any tricks or techniques to find a large parcel of land like this?

yes I see most of this advice above as assbackwards.if you don't know how to figure out what a deal is.. you don't know how to present to a seller and your don't know how to close.. its all moot. the amount of people that blow what little money they have and just send out letters etc with no skills to convert those leads are really wasting time money and energy and will usually just fade away into the sunset.. probably 95% who try to wholesale this happens to.if one was going to study anything its sales techniques ,, close techniques , and one thing agree with above is pick a very small area and become an expert in what a deal is.I see far to many wholesalers just getting leads throwing them up on the wall and preying..
