It always helps for clients to have personal credit cards with the banks we utilize for our funding sequence.
Larger banks are considered Tier 1 cards such as Chase, Bank of America, US Bank, Wells Fargo, American Express, Capital One etc.
But if a client does not have cards from larger banks it is always good to look for Discover, Synchrony, Citi etc.
The lower tier cards are the credit builder ones like Credit One. They aren't the best because banks are aware of those cards and what their purpose is.
