legal fee is based on your selling price

u wouldn't need to pay stamp duty, it's paid by the new buyer, which is also based on your selling price.

your real estate tax is based on NETT PROFIT (you can deduct certain items such as legal fees incurred in buying/selling the house, agency fees, renovation fees etc).

u cannot deduct management fee or bank interest from ur real estate tax.

if after deduct, you're making a loss then u no need to pay anything.

if got nett profit then:-

below 3 years - 30% of nett profit
4th year - 20% of nett profit
5th year - 15% of nett profit
>5 years (provided you're a malaysian individual) - no real estate tax.
