What to do when you want to stand out from the crowd of brokers trying to cash in on the Williamsburg condo boom? Incorporate the word ‘hipsters’ into your marketing campaign and recast it as an educational experience. Transparent? Maybe. But see, it worked: We wrote about it. Last seen in back in January, this Benjamin James-sponsored event purports to offer the freelance creative class the skinny on how to bootstrap into home ownership. Though “Home Buying for Hipsters” does have a myspace page (with 152 friends, no less), the organizers emphasize that Thin Lizzy t-shirts are optional. The “class” meets tomorrow night at 6:30 pm at the Treehouse at 430 Graham Avenue.
