I'm an investor & sub-sale buyer. The landed property is gated & guarded, freehold land, strata title issued but the State Authority places a restriction in interest in the Land / property. So, the State Authority Consent is required for sub-sale. Further, the developer is not issued the vacant possession to the new purchaser(s) until such time the strata title is registered under the new purchasers' name. In short, sub-sale will take some time to complete the transaction i.e obtain the state authority consent will take months. Worst part, the developer is not allowed the new purchaser(s) to stay or renovate the property although all legal documents have executed & stamped (SPA, LACA & etc between the original purchaser(s) with the new purchaser(s)). Don't understand why the developer have such powerful right?

Yes. Fully disbursed. Bank & lawyers confirmed & acknowledged.
