There are limited numbers or other facts from before 1900. What is clear is that renting or tenancy of land and house found its origin in the Middle Ages, or even before that. The population was by far oriented on the agrarian way of life en the property or use of land was therefore one of the most important sources of income. Poor farmers leased land of a landowner and built a house on it by themselves. Permits et cetera were unnecessary, except tht the landowner wanted to collect a compensation (money or a part of the harvest of the land). By this means, a house was already for rent back then, although we do not know any renat contracts. To construct a house by oneselves, which remained in the family, was more common. Commercial renting of houses probably first started later.
