Or, maybe we need a different model than PLD.
As I understand it, the Australians have the Defence Housing Authority. Homeowners in Australia lease their houses to DHA, who then sub-lease them to service families. Why could that not work in Canada? People in the military could buy a house in place they like, but when they get posted, instead of selling it, they get an incentive to lease it to CFHA who then leases it to other CAF families.
They are still building equity, have low risk of managing a rental property and have a house at the end of their career. CFHA is not stuck managing a larger capital portfolio of PMQs (definitely keep PMQs- just add this ontop).
