A place to live without having to handle maintenance/upkeep themselves, to be approved for a mortgage, save up for a downpayment, or to have to sell (and navigate all the mess of that process) when they need to move.
And you end up paying for all of those anyway, plus extra. Minus the equity increase as the house appreciates in value over time. The only party it makes long term financial sense for is the Landlord.
the maintenance costs passed to the renter are dispersed across time as well, so they aren’t having to foot the full cost of say, a new fridge suddenly.
But the landlord charges enough above the mortgage payments to cover that cost, on top of the extra added for profit. The renter could save that extra money, cover the sudden cost of a fridge or washing machine, and have money left over vs renting.
