For me, a big part of the purchase equation was the "arrangement" of the property--the shape of the property outline. Does the property boundary have big "arms" extending into neighboring properties or "coves" of neighboring property sticking into the property that would increase the influence of neighbors' hunting pressure? Preferrably, you want the property to be as "square" as possible.
Secondly, what primary type of habitat does the property have and do surrounding properties have something much different? It would be tough to draw deer to a property if the neighboring property is exceptional deer habitat.
Location, as in county. Athough I had been looking for property along the TN and AL or MS border (at the time, that's where the highest deer densities were), the county I eventually found property in was acceptable. I certainly wouldn't buy deer hunting property in a county that is struggling to produce a huntable population.
Size and price were last. Now the price I got was fantastic, but honestly I had bypassed much larger and cheaper properties because of habitat problems (land that had just been clear-cut).
