So why would it cost so much to have a little hack like this on your document? This little green chop is actually a necessary part of real estate contracts and is called stamp duty. For example, your landlord wants to evict you from the house after renting his house for two months. But the agreement states that you can stay in the house for two years. The calculation is easier here. In the previous example of RM1,700 per month`s rent, the management fee is RM150. Therefore, for a lease of one year or less, the total amount to be paid (stamp duty and administrative fees): (RM82 + RM150) = RM232. Stamp duty is a tax levied on documents with legal, commercial and financial implications. It would cover things like leases, land titles, and even insurance policies. .
