If you are only purchasing one property and you don't foresee you will purchase another property in the next 10 years or you don't foresee you to move your house until the end of your loan tenure, you may opt to MRTA. If not, it's recommended to get MLTA because one MLTA may cover multiple properties since your outstanding amount is reducing over the years while you paying off the loan. Whereas, most of the time, MRTA is attached to the property and while you are selling off your property, the MRTA will be surrender.

Nope because you have absolute assign the MRTA to the bank. The MRTA is not "owned" by you anymore, the owner of policy is now CIMB.

You can't surrender the policy until the policy is assigned back to you when you fully settled the loan. This is the reason life insurance have better flexibility comparing to MLTA/CLTA because in life insurance, you own the policy instead of the bank.
