Meet the Person Behind the Promise
Real estate is one of the biggest decisions you'll ever make. I don't take that lightly.
My name is Jack Ma. I've been a licensed California Realtor® for over 15 years, and in that time I've had the privilege of helping more than 300 families across the San Gabriel Valley, Chino Valley, and North Orange County buy, sell, and navigate some of the most important moments of their lives.
I built this practice on a simple belief — that clients deserve more than a transaction. They deserve a trusted advisor who tells them the truth, shows up when it matters, and stays connected long after closing day.
That's why my commitment doesn't end when the deal closes. Whether you need a market update, a contractor referral, or just someone to talk through your options — I'm here. That's what being your permanent real estate resource means to me.
I'm bilingual in English and Mandarin, deeply rooted in the communities I serve, and genuinely passionate about helping families make smart, confident real estate decisions.
When you work with me — you're not a transaction. You're a relationship.
Where Local Expertise Meets
Personalized Service

I'm not just a real estate agent — I'm your trusted partner and long-term resource for everything real estate.
Deeply rooted in the communities I serve across the San Gabriel Valley, Chino Valley, and North Orange County, I bring 15+ years of local market knowledge to every client relationship. I know these neighborhoods — the school districts, the streets, the price trends, and the people — because this is where I live and work every day.
My approach is simple: give you the right information at the right time so you can make the best decision for your family — whether that's selling now, buying next year, or simply staying informed about your home's value.
Every client's story is different. My job is to listen, understand what matters most to you, and deliver a real estate experience that feels personal — not transactional.
Whether you speak English or Mandarin, whether you're selling a family home or navigating a probate sale — I'm here for you. Not just for the transaction. For the long term.

Frequently Asked Questions
Everything you need to know about working with Jack Ma — serving homeowners, buyers, and investors across Los Angeles, San Bernardino & Orange County.
I serve homeowners, buyers, and investors across three counties — Los Angeles, San Bernardino, and Orange County. My primary markets include Walnut, Diamond Bar, Rowland Heights, Hacienda Heights, West Covina, and Covina in the East San Gabriel Valley; Chino Hills and Chino in the Chino Valley; and Yorba Linda, Brea, Anaheim Hills, Placentia, and Fullerton in North Orange County.
This tri-county footprint is one of my key advantages — I can help families move within this corridor without having to switch agents. Explore my communities →
Yes — sellers are the core of my practice. 80% of my business is working with homeowners who are ready to sell or planning ahead. I bring a deliberate strategy to every listing: pricing analysis, pre-listing preparation, multi-channel marketing, Zillow Showcase placement, and skilled negotiation to maximize your net proceeds.
My approach isn't about waiting for a buyer — it's about creating demand before the home hits the market. Learn about my seller process →
My average list-to-sold price ratio is 101.1% — meaning my sellers consistently close above asking price. For context, the overall MLS average is 99.9% and the West Covina market average is 100.6%. That difference translates directly to more money in your pocket at closing.
This isn't luck — it's the result of deliberate pricing strategy, strong marketing, and skilled negotiation on every transaction. Ready to see what your home could sell for? Get a free home valuation →
Yes — I am fully bilingual in English and Mandarin Chinese. A significant portion of my clients are Chinese-speaking families across the San Gabriel Valley, and I understand both the language and the cultural nuances that matter in these transactions — from multi-generational living considerations to extended family involvement in the decision-making process.
I also maintain an active presence on WeChat for clients who prefer that communication channel. If you or someone you know would be more comfortable communicating in Mandarin, please reach out directly at 909.610.5188.
Yes — I am a Certified Probate Real Estate Specialist. Probate and estate sales involve a unique set of legal requirements, timelines, and family dynamics that require a different approach than a standard transaction. I have extensive experience navigating these situations with professionalism, sensitivity, and efficiency.
Whether you're an executor, trustee, or family member managing a loved one's estate, I can guide you through the process clearly and help you achieve the strongest possible outcome. Learn about my probate services →
My marketing strategy goes far beyond simply listing a home on the MLS. Every listing receives professional photography, a multi-channel digital campaign across MLS portals, social media, paid advertising, email outreach, and direct local targeting. For qualifying properties, I secure Zillow Showcase placement — a premium position reserved for only about 10% of listings — delivering up to 80% more views than standard listings.
I also actively reach out to my buyer database and network before a home goes public, generating interest before the first showing. The goal isn't to list your home — it's to create demand for it. See my full marketing approach →
Competing against cash buyers and investors is a real challenge in markets like Walnut, Diamond Bar, Chino Hills, and Yorba Linda. My approach focuses on making your offer as strong as possible — solid pre-approval, clean terms, strategic pricing, and a well-crafted offer letter that resonates with sellers.
In some cases, I connect buyers with lenders who offer bridge financing or cash-backed purchase programs that allow you to compete on equal footing with all-cash buyers. With 15+ years of experience and 300+ transactions, I know how to position an offer to win. Learn about my buyer process →
From our first conversation to closing day, here's what you can expect: a thorough pricing analysis based on current market data in your specific city; honest guidance on preparation and presentation; a full marketing launch with professional photography and multi-channel exposure; consistent updates on showing activity, buyer feedback, and market shifts; and skilled negotiation to secure the strongest possible price and terms.
I also offer an Easy Exit Guarantee — if I'm not delivering on my commitments, you can cancel at any time with no strings attached. I earn your business every day. Book a free strategy call →
Market conditions vary by city and price point, but well-priced, well-marketed homes in Walnut, Diamond Bar, and Chino Hills typically go into contract within 2–4 weeks. In North Orange County — particularly Yorba Linda and Brea — well-positioned homes are moving in 30–45 days on average in the current market.
The key factors are pricing strategy, presentation, and marketing reach. Homes that are correctly priced from day one and launched with strong marketing consistently sell faster and closer to — or above — asking price. Find out what your home is worth today →
