can you still get a pro rated exclusion?
No. Since you did not sell the home within a reasonable time after your move, but intsead converted it to rental use (which is a form of business use), you don't meet any of the above criteria at all - not even for a partial exclusion.
If the property was your primary residence for at least 730 days of the last 1826 days you owned it, then you qualify. The look back day count starts from the closing date of the sale.
