Allow me to share a million-dollar secret: "Back in those days before the emergence of corona virus, many developers want to sell the large number of unsold units despite openly and shamelessly shouting "last unit for sale to be your ideal home."
These developers engaged multiple sifus and gurus who then organize seminars to "educate" the mostly innocent public at large on how to join property investment with the ultimate objective of selling them lower-than-bank value property. Those property price is in fact jacked up. Then the cash back gimmick starts to come along. Remember those compressed loan news articles? Those are the ones.
After some time, even banks don't want to do any more. Developers have no choice, then they do bulk bulk purchase. For first few projects, it did succeed, but after that a lot of projects using same trick got burned.
Few years later, the developers had to change their tactics. You know what, they now talk about cash flow cash flow cash flow, you know why? because those are for suckers. MCO strike and people are afraid of losing rentals. So they adapt at whatever market want and continue to do their seminars. The best part? You had to pay a shitload of money to join these seminars as buy ins, once you joined it there will be package offered. You will definitely take it cause you already paid for the seminars.
Now it worked like this, previously it was the property selling, now it was the renovation/airbnb package selling, see the difference? after they execute the package, they promised to find tenants and subsidies the tenant to stay for a while. How they subsidies it? They can even request rebates from the agents, think about that lah! Imagine those owner take out RM70k package, they had been promised RM5-6k, for first two years they get the tenants to cover for them, then the rental follows market rate RM3-4k, this type of scenario I seen too much."
Yet there must be differences between fully furnished nicely renovated unit and a bare empty unit, right?
An acquaintance of mine bought quite a few units at KLCC along with his staffs and friends. All rich guys with listed co background. My acquaintance renovated RM100k and rented it out at RM3k. His staff just rented it out bare at RM2k. The difference of one thousand ringgit. That is in KLCC. Imagine here at Bangsar South. Think about it. For the difference of one thousand, you'll need to first spend RM100k for it. In ordinary cases, even taking whatever package will cost the owner a whopping RM70k, it is a risky propositions.
And along with it a lots of owners are thinking the same and everyone else doing the same, it is not easy to fight for the same group of renters who are willing to pay such hefty rent? RM5000 is not a small amount. Look at that super atas building, they want RM7k rental, what they end up with? --- Low occupancy.
What about the property agents? They mentioned they rented out? and keep on emphasizing got strong demand?
It matters not. what matters is the restriction. some buildings starts to ban airbnb, some buildings ban students, some ban Africans or blacks. given the proximity of UM around Bangsar South, surely some restriction will be in place for these buildings. Go find out the restrictions then talk. Even someone offered sky high rental, if the building ban it, it is useless.
And it's all comes down to demand and supply. Rather than figuring out how much price it can fetch, figure out the factors why other similar building with similar location is fetching that level of pricing.
And to answers most potential renters' confusions, many agents are listing a high price with the objective of getting owners' profile and data. If they list low low price meaning they want to get tenant contact and offer them somewhere else

Not sure why you post this in Southlink thread but I can conclude you have zero clue of market demand in Southlink.
