From an investment perspective, East Coast currently fetches the lowest rental yield compared to the rest of Singapore. But because the "east" part of Singapore is the most populated and dense (the top 3 most populated districts are all in the east), there is a fairly strong demand as people like to stay in familiar areas (e.g. near parents). But I suspect over time, people will move out of their comfort zone and move to more open and spacious part of Singapore. The higher temperatures (heavily built-up) frequent bush fires in the east, e.g. Tampines and Pasir Ris also makes the air there smells funny nowadays.
The east coast prices have doubled over the past couple of years which destroys its value-for-money advantage. Transport is also a problem since there is no MRT close by.
If there were an overhead mono-rail along the ECP on the water-side between say Suntec and Changi this would be huge plus.
However even around the quieter areas, Singlap Neptune Court, Fernwood, Mandarin Gardens etc remain over-priced with agents sending flyers "to buy your apt" and "to sell your apt" both claiming huge demand exists when the exact opposite is the case,
Elsewhere closer to Bedok MRT and other MRTs there are very nice 3-bed condos for S$1,500 - 2,500pm which is more closer to value-for-money and for the number of times I go to ECP, a near-by MRT is now a higher priority and would suit me better.
