Ideas/techniques to inquire about vacant land from the owner

[William J Hamm]

I recently started walking around a few neighborhoods in the area so my FitBit will be happy after I've reach my 10,000 step goal for the day.  During these walks, I always look at houses. Walking for $$$.  I noticed that some houses were next to wooded areas or wooded lots.  I have checked the county GIS map and I found that those wooded areas or lots are owned by individuals.  There are no for sale signs on any of the wooded lots.  The property taxes are paid up to date on all the lots I've found.

I would like some ideas or techniques for approaching or mailing the land owners.  I would like to purchase the land and build.  Bring your creativity, what works, what does NOT work, experiences.  I would like some options for the best chance of success.  Thank you in advance to the BiggerPockets family.
