for first house purchase, you are entitled to 50% remission of stamp duty for the transfer and for the loan.
In order to be entitled, you must meet the following conditions (valid from 01/01/2015 to 31/12/2016):-
(1) purchase price must be 500k and below;
(2) It is a residential property - SOHO, SOVO and SOFO excluded;
(3) You do not own any residential property (be it by way of purchase or inheritance or gift and regardless whether co-own or owned by you exclusively);
(4) you have not used this remittance before.
As for what you should look out for, I believe the usual things would be:-
(1) check and research on the property you would like to buy. Compare prices and rental rates, vide brickz, mudah, iproperty etc.
(2) arrange to view a few properties. Check whether title issued. Speak to management, security etc to get more info.
(3) Negotiate on price.
(4) check on loan entitlement.
(5) if you decide to purchase, you will need to sign the letter of offer, get financing, appoint lawyer.
