I would like to get some opinion on this issue as i'm not very well-versed in property matters...

Say i live in an area where the MRT project is announced (pretty much walking distance)... Certainly my property would appreciate in value... But let's say my area is already very well-developed and there aren't any more development planned in the vicinity (shopping malls, offices etc) so the MRT project is pretty much the sole reason for the appreciation of the surrounding property... The project would take years to complete, so would the prices of the property continue to rise throughout those years? And if i'm planning to sell my property, when would be the best time? When it's completed? Or wait a few more years AFTER it's been completed? Is there a risk that after the project has been completed, the property prices would then reach it's max and start to depreciate? Thanks for any opinions on this...

but what if i want to sell because my family just can't stand the noise and overcrowding (which would be much worse later on)? And the idea of renting it out is also out of the question as we could use the money for a home in a more "relaxing" location..
