Yes, I can handle multiple buyers in multiple cities at the same time. I'm here to negotiate for you and doesn't need to be in person anymore. All the signatures are done through docusign or other electronic means in the showing of a house is not a big deal that you need to have a buyer broker with you to see it.
Obviously I'm going to do my due diligence and either I or one of my licensed people can go and see the property if needed.
Currently, I have buyers in the SF Bay Area, LA and Philly. The idea of a "local" agent means nothing since the internet has better info than an agent's memory.
