Would appreciated if anyone here able to explain in details what is CCRIS + CTOS + DSR ? Normally why it will cause blacklist and make us not able to buy property?

As I know, ptptn, credits card will affect one of these..

They won't affect you if u buy in cash without taking loan

Banks approve your loan based on your credit score. If you're a bad scorer they will judge you as unable to repay loan on time, thus borrow you less as you're not a good payer. Just imagine you borrow your friend money and he keeps procrastinating paying you back the money, will you lose trust in this person?

 CCRIS records all the financial information (mainly for loan)  you have with the financial institution, centralisted by BNM. 

CTOS includes the financial information not only from bank, it may contains your outstanding bills/debt from other company, such as TM, Yes, etc, if you does not make payment to them and they wanted to blacklist you, then they will lock a report to CTS.

For PTPTN, credits card limits and usage will appear in CCRIS & CTOS.
