Prices on land in the DeRidder/Leesville area can vary greatly by location and use. For example, vacant land located off a local parish rd (rural area) will be less than vacant land located next to a more popular road or hwy (i.e: US-171, etc). Land used for residential/agriculture purposes in rural areas that is cleared and fenced will be higher than land w/ overgrowth, brush, and small trees that would need to be cleaned and cleared. Fortunately for you there are many land listings that offer a variety of acreage and locations.
It is best to contact an agent for a complete list of available land listings, bc real estate websites like Trulia doesn't feature all vacant land listings.
