JB market has been under performing ever since the Asian Financial Crisis. Comparatively, JB has not done much in terms of property prices up until 2009/2010. So, I am not surprised that you have been watching the space ever since! In fact, speaking to a few Johoreans, most still lack confident with JB properties (their home ground). Most Johorean would buy for their own stay but invest elsewhere. They would rather invest in Sg, KL or Penang. I also dont blame them for what they have gone through over a decade or so...
IMHO, JB has merely played the catching up game (with owners/investors coming from Sg, KL, Penang etc) thus far. So, if you think the prices are already high, you ain't seen nothing yet! The Johorean are just numbed to all these fanciful development around them in Nusajaya. Well, I dont know about you, if PM Lee sees it and Najib sees it and Johor State supports it - you either see it or missed it!
You can't blame anybody for it.... I do hope you seize it.
Cheers
