My bad misread where you said that you could afford rent. It seems like you are making the smarter play if you're really interested in home ownership. I think living at home for 2 more years till you...
OP you seem to have an actual reason for living at home, nothing wrong with it trying to save up to make a down payment. If you can't afford to rent then why would you waste your money doing so?
In on getting compensation from bb.com, I remember the good ole days of the pron forum and all the raids on other forums/sites. Fun times and lulz were had.
