Lastly, I do have enough cash reserve to acquire more property at the moment, which is my plan in the next 2-6 weeks. 

Both me and my brother are at this stage at the moment, I'm browsing all loans that I can that will seem beneficial between me and him.

You get your money without the tax hit at the moment and hopefully continue to profit off them,   If the objective is long term passive income, it doesn’t make sense to sell them… it moves you away from your goal post.

but get your point no tax at that moment.
