Not really, although if you have happen high outstanding charged to your cards when bank/lender do CCRIS search on you, they'll lower your credit score when assessing your repayment capability. This is because they don't actually get the full details of what outstanding you have (example, instalment plans, they'll only see the FULL amount owed not your monthly repayments amount)

Yes, and don't spend too much until loan approved 🤣
