PD Waterfront service apartments would be a better bet.

Incidentally, I am quite familiar with Malacca too since I travel there every week, for work related stuff.

Malacca's property scene is much more active, with more volume. I am guessing you are referring to Straits Residence? My response will always be, 'What's next once you get back the property?' or 'What's next if they don't extend the contract anymore?/Only for the first 3 years?'

Worth to highlight that it will be a real challenge to handle it on your own, especially if the rent is for short term only/a few days. The high ROI (6%) that developer is offering is based on the daily rental model, which will yield higher returns but at the same time, take much more effort since there is housekeeping and so on.

Unless you have a few units and have the time, and also a maid, I think it's better to look at other opportunities, it's just not worth the hassle, in my opinion. Market/demand for rental will be there, but are you up to it to do the dirty work on a daily basis?

Meet guest, collect deposit, record details, pass to them the keys, collect back keys, check suite condition, do housekeeping.
That's one complete cycle.

i already book that unit
