If you look at the form that she wants you to fill out, you'll have the name of the program. And she probably has a caseworker/program administrator contact that she should be able to give you, who can explain how things work, what the duration is, whether they have any obligations in addition to your own lease, whether it's direct or indirect financial assistance, whether you need to submit your entity information so that they can mail you a paper for tax purposes, and things like that.
I've worked with a few independent rental assistance programs in the past-- through the workplace, or a state-run regional program that helps people get control of their lives. Everyone's different, but being able to talk to the people behind the program helps reassure me as to what we're all agreeing/committing to. --137.118.xx.xxx
