Generally speaking, the withdrawal amount of a credit card is half of that of a credit card. If the landlord's credit card limit is 20,000, the withdrawal limit is 50% of the credit limit, that is, 10000.

The 5,000 yuan found by the landlord should be the available withdrawal amount, which means that the landlord may have withdrawn the cash from this credit card before and did not return it, occupying the available withdrawal amount or the landlord has spent15,000 yuan on the credit card (the credit card withdrawal amount is within the credit card credit limit, which means that if the credit card is used up, there is actually no available withdrawal amount to use, in other words, A 20,000 credit card can charge 20,000 cards and withdraw 1 10,000, totaling 30,000, but the credit card and withdrawal add up to 20,000, of which the withdrawal does not exceed 1 10,000).

If the landlord has other questions, you can ask.
