Once you buy your piece of land, whether you want to build a home on it or keep it for a recreational reason such as hunting or off-roading, you need to get it into habitable shape. Preparing the land in general helps protect any structures on it and keeps trespassers out, ensuring your time on the land is a lot more peaceful. You'll have specific tasks to complete that depend on the purpose you've assigned to the land, but in general, these three need to be done for any property.
Aerial Photographic Survey
Even if the real estate agent provided you with photographs of the land when you bought it, you should arrange for a full aerial survey of the land as it is right after you bought it and the purchase process was complete. That ensures you have the most up-to-date information on brush location, lake or river flow, animal and pest infestations, and so on. Remember that the completion of the purchase will take some time, so the pictures the real estate agent showed you will technically be older even if they were new when you first started looking at the land.
Clear Old Brush
Now you need to clear old brush. You don't need to clear forests, grasslands, or any other healthy plants, but you want to remove old brush to reduce the risk of brushfires. Old, dry brush can spread flames like nobody's business, so removing what is essentially natural litter helps keep the land and any people or structures on it safe. You won't remove the fire threat entirely (unless you've purchased desert land that has no plant life on it), but removing the brush makes a huge difference.
Shore Up Fences
Inspect the fences that surround the property, and fix or replace any that are missing or in poor shape. These fences keep out larger wildlife and also prevent people from wandering onto your land. If you have land that you want to use for hiking or rockhounding, for example, you don't want strangers running over it in ATVs without your permission. Ensuring the fences are in good shape protects the land from unwanted intrusion.
Your real estate agent can help you find land that is well suited to the purpose you have in mind. Off-roading, fishing, ranching — no matter what recreational pursuit you're planning for, there is land out there that is perfect for you.
