Meet the Team

Hi there,

I am Billy, the founder of Earth Real Estate. I have been running this business for 20 years,

People often ask me how Earth Real Estate came to be and why I chose that particular name.

Truth be told, the business was born out of the basic yet vital need we all share on this earth; the need for a place to live.

Growing up in the Bay Area I was grateful to experience the security and peace a home provides. I witnessed firsthand how the stability and comfort of a well maintained home impacted the whole person.

As a young adult I learnt the value of hard work, the pride of ownership and the responsibility that came with owning a home. I knew I wanted to contribute to helping people find a home, maintain it and give property owners the peace of mind that their property as well as the tenants’ residence are well taken care of. I saw it as a beautiful cycle where I could serve two sides, property owner and tenant, ultimately acting as an intermediary and problem solver.

In the first years, we primarily focused on residential sales. As we grew over time, our clients had a greater need for tenant placement. We quickly embraced this naturally given opportunity.

One day, an owner asked us to collect rent while he was out of town. I remember walking out of the apartment on a Friday night with a backpack full of money and thought there must be a better way to safely and reliably transfer money from tenant to owner. That’s when we started to pursue transformation and (continuous improvements). *We saw our calling to embrace a full service property management business where the right systems are in place, modern technology embraced and human interaction valued. Our diligent work towards a high-standard service led to increased satisfaction and referrals which make up the majority of our clients.

We are continuously improving, never sacrificing our values and belief that relationships stand above all. Over time we honed a process to build a simple and straightforward property management business where we help owners build a financial legacy for their family and help tenants to be able to live in a safe, well maintained home.

It’s been an incredibly rewarding journey which we have so many people to thank for. Most of all, we fell a deep sense of responsibility and privilege to serve the owner and tenant so they not only live but thrive.

Thank you for taking the time to read. If you have any questions or want to give Earth Real Estate a try to help you create a more fulfilling future, contact me directly at billy@earthhh.com.

I look forward to hearing from you.
