Last year Chase offered 100,000 points for a home mortgage. That offer was stackable with a fee rebate that required signing up for automatic monthly payments, and Chase Private Client customer discounts also.
One thing we learn about the Chase Sapphire Reserve cardmember population — in addition to average credit scores (785) and annual income ($180,000) Chase has shared before — is that “[t]he average Reserve customer has … more than $800,000 in deposits and investments.” So they figure a down payment shouldn’t be a problem.
