For our final heat of the week, before all this week's winners go head-to-head next week, it is all about leading real estate women. Yesterday, Atieno Williams of DC Home Buzz pulled ahead of DC Living Real Estate's Debbie Singleton. And today, we're witnessing Cristina Sison of Keller Williams facing off with Sheila Simkin of DCRE. Both ladies have their hands on the pulse of this city's real estate market. So who will reign supreme today?
