<snip> They both claim that current building code in Raleigh requires R49 insulation in new construction and that any old homes sold now must be upgraded to current insulation codes at the sellers expense.:icon_scra This especially struck me as bandsaw since we're currently selling a townhouse in the area and our agent didn't inform us of that supposed requirement when we listed last month.

This is misunderstanding (or misinformation) about the Cap and Trade federal act passed by the House last year. Note this act is not law yet.
Basically, that act, if passed, would provide financial incentives for the *voluntary* improvement in energy efficiency for existing residences. Feds give the money to the states, who gives the money to the residents for improving efficiency. This is in addition to the current and so-called Cash for Caukers program handled via fed income tax credits.
It also proposed significant mandatory increases in efficiency requirements for new houses, but this would only affect houses built IIRC starting in 2012 - if the act ever passes.
