Devoted - It took me one and half years to find a house I like.
Understanding - I am very picky and OCD about everything. The smallest thing would turn me away from a house within seconds of getting there.
Knowledgeable - Not only did he know about all the rules and regulations, he knew about construction, being able to tell you about the quality of the house, what materials were probably used based on the year of the house, and he would point out flaws in the house that I didn't notice.
Thanks again, John for helping me find my first house.
