The Bilt Mastercard has no annual fee, lets you earn points paying rent on your card, and has bonus categories similar to a Sapphire Preferred Card as well (2x travel, 3x dining). If you rent an apartment or house you can be 50,000 points richer each year with this card, and points transfer to great airline and hotel partners.
There’s a waiting list to get the card, but they gave me a code to skip the waitlist to share on this site. I do not receive referral credit of any kind if you do.
