Mary Fung

I have a background in finance and accounting. Prior to finishing my degree in business accounting, I worked for Deloitte & Touche preparing financial statements for audits, corporate and individual tax returns. I also worked for multiple private companies handling various levels financial responsibilities. In 2000, I decided to dedicate the next stage of my life to raising my children. After 15 years, I returned my attention to pursuing my professional dreams. I am excited and proud to say both of my children are close to finishing college. My dreams have led me to explore opportunities in real estate and mortgage finance, leading to professional licensing both the DRE, and NMLS.

My intricate understanding and knowledge base of corporate and individual accounting sets me apart in the finance field due to the complementary skill-sets of operational accounting and personal finance. My background as a financial accountant allows me the opportunity to add unique insights to my clients in their financial decisions. My clients can expect the same determination I used in raising my children, coupled with my experience in complementary industries to best meet their needs. At the end of the day, my interests are in steering sound financial decisions because I genuinely care for my client’s financial freedom and successes; a strong financial base promotes success in other areas of their lives

In my spare time, I enjoy a night of board games and reading with my family, and trips to parks and reservoirs.

I have insight into ever changing market dynamics, mortgage products and listen deeply to clients needs, which in a complicated real estate transaction can be the most valuable skill of all.

Accountability and Trust:

People do business with and refer their clients to individuals they trust. Staying on top of loan contingencies, setting proper expectations and meeting close of escrow dates can mean the difference between a happy customer or an irate one. I pride myself on open communication, due diligence and organization. When a client of mine gets their keys and opens the door to their future it completes a transformative process which I am honored to play a part in.

Residential and Commercial Financing:

In my career I have had the privilege of selling and financing a wide variety of condominium projects, single family homes and multi-family dwellings throughout the bay area. This breadth of experience has allowed me to work on a variety projects including small apartment conversions – built by Bay Area families – all the way to residential towers that make up the San Francisco and Oakland skylines. The nuances and hurdles of residential and commercial mortgage finance are significant, but with the proper planning and know how it [...]
