BUSINESS INSIDER - July 20 - Elite matchmakers shared their vetting process for high-net-worth clients as part of Business Insider's "Dating Like a Millionaire" series. Two of the matchmakers said they make house calls to get a better feel for a millionaire's lifestyle and personality. An organized home can indicate that the owner is a grown-up, whereas a messy home can be a red flag. "You can tell a lot from a person by looking through a keyhole," said Mairead Molloy of Berkeley International, who is based in London. Berkeley's pricing starts from £15K and goes up to £60K for private headhunting, with a year of unlimited introductions. Highly tailored packages can run up to £100K. Mother-daughter matchmaking duo Janis and Carly Spindel of Janis Spindel Serious Matchmaking Inc. in New York City also make house calls. They said: "We go in the fridge, their medicine cabinets, and their closets."
