"As first time buyers, it was great to have a helpful and understanding team on hand to deal with the purchase. Diane was great at getting things pushed along up the chain leading to a problem free transaction. She was also understanding and patient while we arranged our mortgage, which took longer than expected due to our first time buyer situation."
