If the credit card limit of the landlord is 5000, then the withdrawal limit of the landlord's credit card is 50% of the credit card limit, which is 2500. Because no matter which bank's credit card, the withdrawal amount is half of the available credit card amount. In addition, if the landlord uses a credit card to spend, the amount that can be swiped is the total credit card available limit. That's all I know. I hope my answer can help the landlord!
