First you ascertain if it is designated as bumi lot or it's just that the owner bought it with bumi discount. There is a difference in both. If just bumi discount, then no worries, go ahead. If bumi lot, then you first need to check with the developer as to the particulars of the Master Title and ascertain the restrictions placed by the State Authority.

In most instances of bumi lot, transfer/assignment to non-bumi is not allowed, as it defeats the purpose of bumi lot allocation. You can apply to the State Authority for consent, but it is not easy to obtain same, especially for subsale. If new development, the developer can back you up by showing supporting documents to prove that they have advertised and tried to sell the bumi lots to bumis, but no response. So they assist you to open bumi lots up for non-bumis to take up.

Some people claim can do under table, under water and under a lot of things to get consent but your bear the risk of all that as all that is unofficial.
