According to the contracts from that time, there existed houses with one or two mills. Lease prices on an annual basis ranged from 110-131 perpers for a house with two mills, or 51 perpers for a one-mill house, and the lessees were mostly noblemen, citizens, or Konavle people from Ljuta and from surrounding villages.
The rent for a two-year lease was paid in four instalments, i.e. every six months in advance; only the last instalment could be paid one month later.
Penalties were also foreseen. The penalty for the delay was one more instalment and, in case such obligation was not paid on time, the lessee and his guarantor were imprisoned in the city dungeon, situated in the entrance to the Rector’s Palace, and were held there until full payment of the lease and the fine were made. Anyone who violated these rules could no longer, either personally or through others, lease or buy shares in the mills.
