I recently lead a round table discussion on viral marketing strategies and that brought to mind two recent, seemingly unorthodox real estate marketing tactics \u2013 \u2018Buy One (House) Get One Free\u2019 and \u2018Up For Auction\u2019\u2026 one more viral than the other, both likely promoted through traditional PR channels.In San Diego, Michael Crews Development is offering to give away a row home valued at $400,000, if the buyer purchases one of their luxury estate homes, in nearby Escondido. “We thought, ‘Why\u2026 (do these sorts of promotions)\u2026 just have to be on Pop Tarts and restaurants? Why not buy one home, get one free,'” Dawn Berry of Michael Crews Development told 10 News in San Diego.Hmm\u2026I immediately questioned the quality of the row home construction and the location. Why would a developer opt to market their luxury homes the same way they would market Pop Tarts? After scouring the web a bit, though, I was intrigued by the viral status the promotion had acquired.A quick glance at some of the major news outlets \u2013 Reuters, Yahoo News, The Street, US News, MSNBC, and The Wall Street Journal Online \u2013 revealed that nearly every major news outlet had picked up the story of the developer\u2019s wacky marketing ploy. Additionally, independent stories started to show up in my Google searches, as well as links to YouTube videos. Finally, bloggers \u2013 including this one \u2013 are commenting on the strategy and seeing it is a \u2018sign of the times\u2019 (or zeitgeist, if you will\u2026)To date, I believe only ONE individual has made an offer on a Royal View estate home, but the exposure has been impressive. I wouldn\u2019t be surprised if Michael Crews Development seeks to extend the offer beyond the original May 31st deadline. So, the \u2018Buy One (House) Get One\u2019 approach is not yet a case study in successful marketing strategy, but it certainly got a lot of publicity and achieved viral status. And, when the Southern California real estate market picks up again, the strategy may just achieve its original goal of closing more sales.Locally, Westrum Development, in an attempt to gain traction for their stalled \u2018Hilltop at Falls Ridge\u2019 development in East Falls, Philadelphia, opted to auction their remaining 11 Phase I units. Many saw the ploy as a risky strategy or a sad commentary on market conditions. However, all 11 units sold and \u2013 at least for now — their lender has been silenced. And, although the auction, which is more common than \u2018Buy One (House) Get One\u2019 didn\u2019t reach online viral status, there were a number of local threads and articles pertaining to the event. Good old-fashioned word-of-mouth also helped, contributing to the sizeable turnout at the auction. On to Phase II!
