Where do you live? The site may be specific to the HUD district that serves the marketing area where you live.
The HUD property site for your area is probably designed by the HUD marketing contractor for your area. HUD sometimes changes marketing contractors, so the site you seek may no longer exist.
I found this great hud website, it has a white background, and has the four hud houses in grey imbeded in the back gound. I lost the link to it when my cpu crashed, and I don’t remember the adress, if any one knows what I am talking about would you please post the adress.
