Having poor credit can hurt your cause but if you have good references and stable income to support the rent often landlords will look past it.
* getting references from former landlords
* offering more security deposit
* asking for a face-to-face interview with the landlord to explain your situation
Speaking with a lender to determine how you can improve your credit is important. Often very minor things need to happen for your score to increase.
