Land- to own or to rent

As a young farmer with only about 10 acres of tillable land owned by my family, the issue I am facing now is finding more ground. To add to the issue, every year more and more farmland is being split up and sold off for development, making it even more competitive to get ahold of any available land. Every now and again there is land that comes up for sale (happens far more often than land popping up for rent) and im wondering if it would be profiable to buy land instead of renting. Keep in mind that with the rate of development in the area any land for sale is pretty expensive. 15 acres just cane up diwn the road for about $8000/acre. Half is wooded the other half is tillable. Anyone have any comments/advice or experience with similar issues?
