While being a responsible landlord requires preparation, knowledge and continuous education, it by no means implies that not having knowledge about specific issues makes one unqualified. The business of landlording is similar in nature (only by comparison) to cooking, driving, and other familiar activities. In that, most people assume that the ingredients, practice, and management are “common sense.”
Anyone who has tried to prepare a Thanksgiving feast is well aware that it is unlike preparing a weekday dinner. Anyone who has attempted to drive in a foreign country soon realizes it is unlike driving locally where the roads and signs are familiar.
Anyone who has attempted to manage property for rental soon comes to the understanding that the ingredients (the laws) and the road signs (the management) are fair more complex than a simple lease signing and deposit of fund. It takes time and experience to get all the ingredients time perfectly in harmony or to travel without a hitch. (Even then, people always have a new method of insight to complicate the rules.)
