My question is does anyone know how long you must actually live in there as a PPR from the date of acquisition?

To qualify for a full CGT exemption, the property must have been your main residence from when you acquired it. If you move out of the property and rent it out, you can continue to claim an exemption from CGT for up to six years after you move out. If you do not rent it out, you can claim a CGT exemption for it for an indefinite period after you move out.
