yeah, im not too sure about it either, but since it IS an essay, and those can be h3ll at times, here's my best...
i think that money should be used for business foremost. mainly because from that business more income can come from, thus also providing money for "house". also because spending money on a business obviously can help that business mature. the only drawback to this would be if the business wasn't entirely appealing.
idrk if this is helpful, but...lol
anyway good luck
