I gotta say Jessie well deserves five stars for all the four criteria above. Her local knowledge is impeccable. By local area I meant a few districts of San Francisco since I only interested in looking at certain districts. She very well understand the whole purchasing process and provided very useful tips in buying your first house.
She is very organized and promptly showing the properties to me that fit my budget and need.
Her persistent and persuading attitude definitely is a plus on her negotiation skill. She got me the condo I need in two weeks.
