One important question, is the Rm2400 rental sustainable? survey yourself or the seller told you one?

As long as the conversion of leasehold to freehold doesn't fully completed, can't take for granted. It is very dangerous to persume it will happen or happen smoothly. Please check properly if the leasehold can be changed to free hold one. Don't trust everything to the seller, although the seller might be a honest person, it is always better to check yourself with relevant authorities to verify it.

It is plain not wise just to save up Rm 2k for not converting he leasehold to freehold (if it is really true).

It is always to check through everything properly before commiting, verbal word carries no weight sometimes, black and white paper does.
