Generally landlords must be comfortable with a prospective tenants ability to pay the rent each month for the term of the lease. A great rule of thumb is 1 month rent should equal 1 week gross salary. A landlord can only determine ones ability to pay by tenants legal source of income. If employed, a prospective tenant can have ready a verification of employment or a person in the company whom a landlord or agent can contact to verify income. If income is from social security or a trust fund or other similar type of resource the proper award letter should accompany an application. Having this inforation available should help a prospective landlord make an imformed decision.
