When renting, the owner has the right to change the terms of the rental agreement at will. In addition, a standard rental agreement is valid from month to month. For example, you and your long-term partner can sign a one-year lease. However, you may want to opt for a monthly lease when you first move in with your partner, as it`s more flexible (in case things don`t work). A tenant looking for a long-term lease may be put off by the flexibility of a monthly lease, which may allow them to be subject to frequent rent increases or indefinite rental periods. For landlords, the cost of more frequent tenant turnover should also be taken into account, including the costs of advertising, filtering and cleaning. .
