Andrea Romero is also known as “The Singing Realtor” — her parody cover of Taylor Swift’s “Shake It Off” (“One Day Off”) in which she swapped out the lyrics for real estate-relevant language went viral last year, racking up more than 200,000 views on YouTube. The Arizona broker has plans to put together more parodies about the daily lives of her colleagues, and when she’s not taking center stage, she’s selling homes, of course.
