The 45-day notice is in the 2006 HUD letter (2006-28.) So it's been around a while.
Not sure about the gov't website on foreclosures - I don't think it's a requirement, though - more of a recommendation? I mean, you have to see if they're a covered servicemember, but I don't think the part about checking the website is mandatory.
