I believe says "the home will be used for your primary residence".
"will be" is different than "has-been". i presume it means going forward (post transfer), you plan on using the home as PR.
i noticed this clause "If you purchase an existing home, you must move into the home within 92 days of the date you register title to the property."
so i guess if house will be built within 92 days you're okay?
