The Livonia Housing Commission uses both. It is mandatory for our Section 8 landlords and we have been doing this for almost 5 years. We do not send statements to the landlords, our computer software vendor (HAB) has a product that we use which allows the landlords to view their payment history on line and print their detail pament history for up to 18 months. This has worked great for our PHA.
We also offer our public housing tenants the option to sign up to have their rent automaticaly taken out of their bank accounts and we have approximately 65% of our tenants who participate.
