There are multiple reasons why one person might decide to rent rather than buy a house. One of the most common reasons could be for temporary living. A lot of people will choose to rent out a home when they know they won't be staying there forever to save money. If you rent a house you only pay for however long you own the house but if you buy a house then you are tied to it until you pay it off. Another reason could be inability to buy and own a house. Whether it be because your credit is low or you just can't find a house that suits you, you might just choose to rent. Also, in case of an emergency such as a fire in your home you might choose to rent a home until the damage is fixed or until you buy another home.
