The average wait time for many Housing Authorities ranges on average from a few months to 10 years. However, I believe you should go to the office and verify that you are still on the waiting list and make sure your contact information is up to date.
I must apologize I do not have the answers for you. I work for Housing Authority but I do building maintenance for them I have no Insight on any paperwork that is handled upfront or time frames on applications or anything.
Thanks! Your answer is awaiting moderation.
