Landlords pick applicants who have track records as good tenants. There’s nothing wrong with this approach, and it works, after all, people are creatures of habitl. But the other factors are less telling. Applicants should consider writing a letter of introduction in which they describe themselves and their commitment to being good tenants, with some supporting evidence, such as college transcripts. Good grades and no “incompletes” spell maturity and follow-through, both qualities that landlords look for.
