I believe you need to resubmit your question. When you mentioned Burlington Trulia pointed your question to NC where we have a small city named Burlington. The Section 8 question though is federal so the guidelines should cross state lines unlike other real estate issues which are controlled by the individual states and can vary. The link below is to the HUD webite and the SEMAP program page. This will allow you to look throught the Section 8 guidelines.
Hope this helps,
