Most rental applications do not require a cover letter, but preparing one can help persuade a landlord to choose you as the successful applicant. Writing a cover letter gives you the chance to speak about your character and demonstrate how you will be a responsible tenant. Your cover letter should focus on the positives, without being misleading or dishonest. Consider writing about your job, interests, and hobbies, and why you would be excited to live in the landlord’s rental property. If you are applying with a roommate, partner, or as part of a larger family, make sure your cover letter describes everyone who will be included in the tenancy.
