For this, you must ask them. I really don't know. Everyone buys with different objectives. Some buy to stay. Some buy to retire. Some buy to punt. Some buy because it offers them freedom. etc.
I suspect a lot of SPRs buy for retirement. They make use of the benefits in SG, save their money and want to eventually retire and die in MY. Which is what the SG govt wants anyway. Help us make money when you are young, but when you are old pls FO and die elsewhere. Pardon my French. Besides, as much as culturally, MY and SG are similar, they are still diff in many ways. MY SPRs frens have certain mannerisms that irk me... so much so that I have stopped asking them out for drinks or to my nite club parties. So quite many of them are more comfortable retiring in MY. Even Singaporeans will retire in JB one day. Just wait and see if I am rite. (Kindly note that I have nothing against SPRs. I am ok having meals and "frenship" with female SPRs. But when it comes to golfing, drinking and chionging, my requirements are a little more stringent.)
As for whether SPRs are punters or not, I am also sure, quite many of them are. Each Malaysian can get 90% loan for 2 properties - add in the DIBS feature, if I am Malaysian, I will also punt.
There are some of us SPRs who constantly get mistaken for Singapoean, pardon me but it irks me that it always happens to me. Unfortunately those of us who came here young, picked up many of teh Singaporean traits, if we're not careful we may have problems reintegrating back home.
As for 'punting', most of the SPRs I know ( and these are people who own a few properties in SG) dont want to take 90% loan as the interest will just bleed them. rates are much higher across the Causeway. As for younger ones who can't afford to pay down, many of them are reluctant to buy until they have enough to pay down or offset with flexi loan at least 50%, except if they are buying for own stay to commute daily. We know from our parents time, how interest just wipes out potential gains and adds risk. But if Ringgit continues to decline, its a good idea to borrow as you're locking in the price and will be re-paying less in SGD.However, your 'investment' may also fall in value in SGD terms.
For all these reasons most SPR's prefer to invest in SG first.
As for retiring in MY, its about lifestyle, its hard for us to stomach the crowds and we yearn for our moderate pace of life as we age.I believe SPR's also feel better equipped to cope with teh crime situation as we know hwo to be low profile and are betetr at taking precautions, am not saying we're smarter, its just that it comes more naturally to us. E.g when we park, my hubby looks for shade, I look for one nearest the shopping centre or guard post.
