Hang on WM we are not comparing apples with apples
What you are buying is a totally different beast, you may be paying close to same price for land, however, end value for Mt Pleasant needs to be much higher to make it work, IMO harder to sell as there are not as many buyers and unfortunately there are many choices when we are talking $1.8M+.
Also different zoning/higher density with what you are buying, therefore you can maximise what you can build on the land.
At the end of the day we are all at the mercy of the market, all we can do is mitigate the risk, but somehow I think you have this covered
