Take that with a grain of salt. I've been renting in the US since I got into college, 5 apartment complexes later and I have yet to see a single place that will not let you pay online. This might be the case for some smaller apartments, but anything bigger and they will always have online payments. I think OP might be a renter in NYC / SF where you have smaller landlords that aren't running 300+ unit complexes.
