The fact is until they have actually sold (transacted), it's all talk. If I made an empty verbal offer of $1M for this property (assuming it really exists), I'm sure Kincella would use this as an example of a property going up 3 folds + and a warning that most won't like it.
Even if you don't take Kincella unverfiable tale with a grain of salt, the thing is if they actually sold and bolt out immediately of the housing market, then I could suggest they have made money. If they pour it back into the property black-hole, it will be a case of easy-come-easy-go. Sound like they are of the latter category.
BTW, anyone who loaded up on Sundance Resources 2 months ago and would have doubled their investment already.
