Letter to Increase Rent is a document that serves as an official notice to a tenant from the landlord informing them of an upcoming rent increase. While the exact structure and language of the letter can differ depending on the rental agreement, generally it outlines the amount of time before the applicable rate change takes place, provides justification for the increase (such as inflation or changes in utility costs), and specifies the new rate. In addition, the letter should include any additional information relevant to the rent increase and contact information should the tenant have queries or concerns. At its core, a Letter to Increase Rent is designed to protect both parties involved: notifying tenants of their impending costs and protecting landlords’ assets while ensuring they remain competitive in the market.
