As the rent prices keep rising, the renter in the end will end up spending much more money in the same duration as a mortgage, won't they? After a few years, when they end up owning more of the property, they can secure a good deal with better monthly mortgage payments.
They can also quite easily set up an AirBnB or get proper renters, if they want to have some flexibility, and in most cases the rent money will be more than the mortgage payments, so if they want to rent another place of their liking, the additional income will offset the monthly costs.
