Although it took Makovik more than five years to close her first deal, she says she now sells up to three historic properties a month, priced from €12,000 ($13,000) to €4 million. She typically takes a 3 percent commission, which last year earned her about 4 million Czech korunas ($161,000). The 400 or so properties she lists range from relatively modest brick and stone manors to palatial expanses with gardens, ballrooms, and enough beds for the ball guests to sleep over.
