How does the 30-day primary residence window work?

Primary-residence occupancy windows show up in several different contexts, from a loan program requiring you to move in within a set period after closing to a property tax exemption requiring the home be your residence as of a certain date, so which one a 30-day window refers to changes the answer. VA and some conventional loans commonly require occupancy within a defined window after closing to keep owner-occupant loan terms valid. Confirming which specific rule applies means checking the actual loan, tax, or program document involved. Joel Boss can help identify which rule applies to your situation.
