CLTA is basically a hybrid product of MRTA and MLTA. The main benefit it takes from MLTA is that it offers a fixed protection over the tenure, though there are still significant downsides to it, similar to MRTA, such as it not being transferable.

In summary:

MLTA:
- Has cash accumulation
- Transferable
- Can select beneficiary
- Coverage can be adjusted according to needs
- Flexible

CLTA:
- No cash accumulation
- Not transferable
- Coverage is fixed
- Beneficiary is bank
- Not flexible

Whether to choose the CLTA or MLTA will depend on your situation, but if you can support it, MLTA will be a better choice in the long run, especially if you buy another property later.

Cheers.
