 Bills now can be paid online, including rent. More rental property owners are allowing their tenants to pay on online platforms, and a lot of those online platforms now are also accepting credit cards. Katherine Hamilton writes about this in the Wall Street Journal. Many are thinking that by using a credit card to pay for rent and almost everything else, they can rank up rewards points and pay for other things. But Hamilton warns those points are harder to get than you might think. Usually when you use a credit card, the fee is around 3%, which is higher than most percentage cashbacks.
