Nope, if you attempt to buy another horse, the seller will tell you that you have bought his last one. This is because horses are expensive to keep in modern times, and being able to sell their manure and urine for money allows them to be worth keeping. Housecarls usually work for the lord of the manor or for the merchant community. They tend animals on land that doesn't belong to anyone in particular, transport goods, and perform other tasks as needed. Usually they are given some land by the lord they work for, but sometimes they can even be given money instead. The more land they have, the more freedom they have. If they don't have any land, then they may still be free, but they can only go so far before they are forced to return home. The housecarl's main weapon is a sword. He may also have a spear or axe depending on what role he plays on his master's team. They are trained to fight just like knights, but since they don't hold land they can't call upon men-at-arms to help them in battle. The housecarl can marry after serving for several years. His wife works alongside him and has equal status.
