1) You need to ask your lending bank whether they are ok without the CCC.
2) If the bank accept the old CF (the original ones from developer) it might affect the bank's valuation report and margin of finance.
3) negotiate with the seller to discount RM10k for you to re apply the CCC.
4) you have to bear the risk of MPSJ may not approve your new house plan application and you need to re-do certain parts of the renovation in order to comply with MPSJ's buildings rules and regulations.
