At some point, I used to give “forever” as the fair estimate of time when E12 is live-able. But seeing things developing recently, it can happen little sooner than that.
Jokes aside, E12 is still advisable for investment purpose only not for house construction plans. It has performed exceptionally well in last 3-4 years and has great potential to double your investment in a couple of years if things go on the same pace.
