It wasn’t quite a “road to Damascus” epiphany, but Rob Serbin did find the road to Little Traverse Inn last year. The Glen Arbor realtor finally sold the restaurant on M-22 for the second time in seven years, this time to Scotsman Graeme Leask, after it sat idle on the market for 18 months. The sale was emblematic of Serbin’s monster year, which saw his company’s net sales surge by 250 percent. Numerous realtors in the Glen Arbor area shared that good fortune.
