When the necessary elements are present equity will always enforce the specific performance of a contract for the sale of land.

"One who has contracted to purchase a particular tract of land cannot get its exact counterpart anywhere, with all its surroundings and conveniences. It is a unique thing, not capable of being duplicated."2

The purchaser of land under a contract of which he seeks specific performance must either prove a legal tender of the purchase price or allege in his petition that he is ready and willing to pay, and show a sufficient excuse for not having made a formal tender.3 The purchaser in a contract for the sale of land is not precluded from maintaining a suit for its specific performance by the mere fact that the land has increased in value, where such increase has taken place after the payment of part of the purchase price, and the delay in the payment of the balance is neither unreasonable nor due to bad faith.4
