I am on Social Security and my income is low.

My advise is to concentrate heavily on social interaction with people.

My professional background is in clinical social work and healthcare administration and, not being familiar with real estate, I was at first skeptical and kept telling myself "maybe one day."

The next best is to put collections against her name and social security. if you don't know her social, it is still okay, as collection agency can get that info. 

Drew,May sound silly, but did you try call, text, email and their social media accounts, this may tell where they are or if something has happened?

You arent a social worker...............................lol.

Adding my two cents here - I think Oakland will be the next (or already is) place for younger professionals in the Bay Area to live and socialize in.

She actually gave us a 6 digit Social Security Number.

Send out new social media requests.

Where that social security number has lived for the past 20 years, Credit score, Nation wide criminal history search, Nation wide eviction search and many other items.We use a tenant screening service called Rent Perfect (formerly Investigative Screening and Consulting or ISC).
