The MCDA maintains two waitlists; the 667 State Elderly Waitlist and the Alternative Housing Voucher Program (AHVP) Waitlist. The average wait time is based on a myriad of factors including but not limited to; number of vacancies, status of Veteran or emergency applications, number of applicants on the waitlist, age of applicant (667 only), or resident status. Local residents and Veterans get first preference. The following is the estimated wait time for each waitlist:
667 State Elderly
| Veterans | Less than one year |
| Elderly Marlborough Residents | Two to three years |
| Non-elderly Marlborough Residents | Three to five years |
| Elderly Non-Marlborough Residents | Ten plus years |
| Non-elderly Non-Marlborough Residents | Ten plus years |
AHVP
| Veterans | Three to five years |
| Marlborough Residents | Three to five years |
| Non-Marlborough Residents | Ten plus years |
The Federal Department of Housing and Urban Development (HUD) Section 8 Housing Choice Voucher (HCV) Program has a state-wide waiting list that is maintained by the Massachusetts Chapter of the National Association of Housing & Redevelopment Officials (MassNAHRO). The average wait time for all Section 8 applicants is about ten years. This waitlist is not maintained by the MCDA.
