Mary and I looked for a property in the Cambridge/Somerville area for around 9 months. Over time I changed from looking from a condo to a multi-family property. She was a great consultant throughout. I never felt rushed to make a decision.
She continues to help me years later. With her contacts and experiences, she is able to give advice on questions I have regarding the property. She is also able to recommend tradesmen when needed. I call her 'the Oracle'.
