Several things to consider. Mineral rights have already been mentioned. Right of ways is another. Sounds like you have access to utilities nearby in case you develop, so hauling them in to the property boundary probably won't be hugely expensive. Timber value is one that you should consider. If the property is for investment, you may want to consider cutting timber pretty soon as use it to pay off the property and then you have many years before you consider building on it and by then the timber will be back well enough, probably. If the property is far enough from a city, you probably don't have to worry about zoning changes, but it is worth considering. Finally, make sure you know about any restrictions on your development of the land. An in-law who lives way in the heck outside of any city, has country restrictions that says that he can't just pull utilities on to the land, he has to build to do that. He also can't just put in a pad or drop a pre-fab and can't dig a well unless a construction permit is approved. They tried to merely build a pole barn and that got slapped down as well.

It may be your property, but it's their rules.
