My goal is to make the process of buying, selling, or owning a home efficient, enjoyable and rewarding for you. See what my clients have said about my real estate services...


Ethan has worked with me as my buying agent a few years ago and more recently as my selling agent and did a stellar job both times. He was very professional while still being fun to work with, he went outside of his way to help me fix the few things that needed repair around my place and was always courteous. He was always on time and was very respectful of any concerns I may have had during the pandemic. He would regularly update me after the many open houses he conducted, and would help me understand all the options that were presented in front of me. Not only would I highly recommend him, but I’m also looking forward to working with him again in the future.

We had the best experience with Ethan.  Very patient, knowledgeable, and professionalism.  We would recommend him highly.  Can't go wrong with Ethan on your side.  He found our forever home.  Thank you Ethan from the bottom of our hearts!

Translation: "Thank you very much for your trust and help.  I am really lucky to have met you.  Your friendliness, patience, professionalism, and gentlemanly manner have left me a very good memory.  In the process of buying a house, you have been patient to help me choose.  Your sense of responsibility and dedication, as if purchasing for yourself, have helped me buy my dream home. This is the first home I bought in the United States.  At first, I thought it was going to be a complicated process but it was really easy because of you.  So, I am very grateful to you.  If my friend is going to buy a house in Irvine, I will be the first to recommend you."




Zhang & Jing, Aliso Viejo

"It has been our pleasure to have met Ethan. From the beginning to end, the process was seamless. We wouldn't have asked for any better service than was given. Ethan has been nothing but professional, knowledgeable and patientHe sent us listings as soon as it was on the market, worked with our schedule to see the homes. Handouts were provided for every tour which helped us understand the market better. Ethan also made sure everything went smoothly with the loan and escrow office on every step, assisted us in providing contractor referrals and many other things. The service he has provided more than exceeded our expectations of a realtor. We absolutely recommend him to everyone."





Meisenhelder, Huntington Beach

"My husband and I just bought a home with Ethan’s help, and he was really wonderful to work with!

In the early stages, he kept us up to date on new listings and was always available to show them to us around our busy schedules. He also gave us great advice on our initial offer when we asked for it and kept us very informed about seller’s responses, inspection schedules and results, and appraisal process. When the inevitable little hitches in the process happened (a termite inspection, for instance, that wasn’t 100% clear about findings), he jumped into action to get a revised report done immediately.

We couldn’t have asked for a better realtor—Ethan was amazingly responsive (I don’t think we ever even had to leave a voicemail!), knowledgeable, and pleasant. He worked very well with both our loan officer and the escrow company to make the whole home-buying process for us virtually stress-free—and that’s something when you’re buying property these days in Orange County!"

Thank you so much for all of your help!  I've never worked with someone with so much professionalism and care for all details!  We genuinely appreciate

working with you!

Thank you!

Yamamoto, Fountain Valley







Translation: "Thank you for assisting us looking and obtaining a lease property.
He worked hard to meet as many of our humble requests as he could.  Showed us many properties that exceeded our expectations.
My husband and I do not speak English, Ethan took care of all our needs without hesitation or  reluctance, however small.
We were able to smoothly accomplish all contractual transactions with his help.  And now, we are enjoying our living in a comfortable new home.
For us, Ethan has been a perfect 100% angent and we plan to ask for his service when we are ready to purchase our own.


Noda, La Palma






Translation: "We are grateful that Ethan took quick actions with sellers to properties we hoped to purchase, and explained to us all aspects of a purchase transaction which were difficult to understand.
He took time and effort to answer our questions, gave us proper advices, and helped us make all the right decisions.
It was important to us that an agent works with professionalism and perfect timing.  We are very happy and satisfied with Ethan who helped us purchase the home of our choice.
We recommend Ethan who is also very skilled in negotiating to any one who is thinking of purchasing or selling his or her home.

実は、購入時のエージェントもEthanでした。 大変良くしていただき感謝しております。
よく住宅の売買のキーポイントは良いエージェントと出会う事と言われますが、本当にその通りだと思います。 迅速、丁寧、誠実、Ethanはそんなエージェントさんだと思います。
そのうえ、英、日、中語が日常的に話せる。交渉に際しても色々有利な点もあることと思います。 日本人として異国での住宅売買は分からない事ばかり。 Ethanに任せて本当に良かったと思つています。"
Translation: "I asked Ethan to be my Realtor to sell my home.  In fact, Ethan was my agent when I bought this home years ago, and I'm very thankful.
It's often said that the key to successful home purchase or home sale is a good agent.  I think that's absolutely right.  Responsive, meticulous, honest - I think Ethan is just such an agent.

Moreover, being tri-lingual and fluent in English, Japanese, and Chinese, I believe Ethan offers unique advantages in many aspects, including negotiations.  As a Japanese living abroad and not at all familiar with local real estate transaction processes, I was very happy being able to rely on Ethan.

Taylor, Irvine

Ethan Sun was our realtor for both the sale of our home in Tustin Ranch, and the purchase of our new home in Irvine.  He was an absolute pleasure to work with!  His skill and market knowledge make him an expert in the industry.  We were very impressed with his ability to speak many languages such as Mandarin Chinese and Japanese; this made it helpful when communicating with many different buyers and sellers in our community.

From handling our open house, to meeting us at various homes to tour, Ethan was always prompt and very professional.  We would not hesitate to refer Ethan to our colleagues, friends and family, and we will be using him again for our future real estate purchases.  He is the best in Orange County!”

Hennings, Huntington Beach

"I worked with Ethan Sun on a recent property purchase, where he represented the seller.  Ethan's professionalism, dedication to detail, and flexibility during the transaction made the difference between success and failure in this deal.  He was always available by phone, text, or email and that really made it easy to get things done for me and my broker.  I was so pleased that I had Ethan take on a rental listing for one of my investment properties and he found a well-qualified tenant within days.  Ethan was on top of the entire process.  I whole-heartedly recommend Ethan Sun for any of your real estate needs.




Wilson, San Clemente

"Dear Ethan,

I can't thank you enough for the ways you have handled the sale of my duplex in San Clemente.

From past experiences, I had a dread of dealings with a Realtor.  As a 78 year old lady, you held my hand all the way, guiding me through the stress of the sale - always there.

Everything was done with professionalism, expertise, attention to detail, honesty, negotiating the price to my advantage, and above all, kindness in helping me through this stressful situation of the sale.

I would happily sing your praises to anyone!

Angelas, Oregon

"Dear Ethan: 

I just celebrated my 68th birthday and Connie and I were reflecting on the significant events of the last year.  We agreed that meeting you was one of the blessings condoned on us by the fates or maybe even better.  We were comparing our agents (both sell and buy) and came to the same old conclusion that Ethan Sun was the most trustworthy, open, honest and personable (I argued against that one) agent we could have had.  Neither of us wants to let our contact with you to evaporate.  You know, we will be coming back to the OC sometime in 2013 so be forewarned that we will let you know when and make time to meet with us for a lunch or even just a cup of coffee somewhere.

We hope you are doing well and we think of you often.

All our very best to you and your family….

Gus & Connie"



Ozaki, Ladera Ranch

"I was thoroughly impressed with Ethan's level of committment and care in helping me find the perfect home.  His communication and patience with me as a new homebuyer was comforting and appreciated.   Even after escrow closed, he contacted me to wish me well in my new home and helped to ensure that all loose ends were tied up seamlessly.



Angelas, Tigard (OR)

"There are few better than Ethan Sun - knowledgeable with excellent communication skills and strategies that work!

Gus & Connie"


Longobardi, Huntington Beach

"Ethan Sun has been my real estate agent for over a year. He has a pleasant demeanor and is easy to work with. He is always prompt for appointment meetings and arrives well prepared with detailed reports. In each one he outlines the residence listed in a full client report including comparable homes in the area and an inclusive breakdown of current interest rates and a mortgage approximation. 

He is reliable, dependable and responds quickly to emails and telephone calls. He represented me in the purchase of my last residence and has continued to work hard showing me multiple listings in various cities throughout Orange County. I highly reccommend him for all your real estate needs.


Lai, Irvine






Translation: "We are really thankful for the care and assistance you provided us in this endeavor.

We truly appreciated that you always responded quickly and precisely.  Being able to sign and execute documents electronically was a major convenience as well.  We were happy of the numerous Open-House you’ve conducted to showcase our home, and felt completely at ease even during our absence when we traveled to Asia.

You were there for us to the very end, even helping us with our move for which we are very grateful.  From beginning to end, this experience couldn’t have been more smooth, and it reinforced our belief that you are a “can-do” professional.

Thanks again, so much.  We hope that our families will continue to enrich this relationship.




Southard, Fullerton

"I had the pleasure of working with Ethan Sun on the sale of my house in Westminster, CA in July 2012. My sister is a Real Estate Agent in Florida and she did some research and found Ethan for me. Ethan was very professional and did a great job for me.

He was very organized and gave me a professional presentation of the current market conditions and comp sales in the area. Ethan gave his recommendations but also listened to my opinions as well. Ethan also did a great job on marketing the property, held multiple open houses and provided very nice brochures of the property to prospective buyers.
Throughout the process, I think Ethan represented me very well and had my best interests in mind. I really liked the "online signature" process which made all the documentation quick and easy and saved me a lot of time and had a minimum impact on taking away time from work.
I would highly recommend Ethan Sun if you are in need of a Realtor.



Strauss, Estero (FL)

"Hi Ethan,
I wanted you to know I believe you did a fantastic job with the successful closing of my brothers home in Westminster.
I could not have chosen a better, more professional Realtor! I would love to work with you again, if you know anyone who is moving to my area here in SWFL, Fort Myers, Estero, Bonita Springs, Cape Coral, Please send them my way.. I will take care of them and you.....

Thank you,



Angelas, Irvine


You showed our home yesterday and we just wanted to drop you a note. Whether or not you sell our home is not the point of this note. We just wanted to tell you what a pleasant and professional impression you made on us. Your clients must feel they are well represented.

We hope to see you again and continued good fortune to you.


Gus & Connie"



Nagano, Cypress


Translation: "Despite being first time home buyers who knew nothing about home purchase, we were able to buy the home of our dreams. We think the biggest initial worry is choosing the right agent, someone who is reliable, whom we can trust. Ethan provided detailed and crucial information in Japanese, and we are thankful that he always thought and acted on our behalf, in our best interest. In our year-long journey, it was not always smooth sailing – some properties we liked but were not able to get, untimely difficulties with lender, etc., Ethan was always encouraging and he never allowed us to lose hope. We will definitely rely on him again when we’re ready to move up.




Hsieh, Huntington Beach

"Ethan was very professional in assisting us with our condo rental. He explained the process well and was very strategic in planning the rental listings. As a result, our property was rental quickly despite being in a community with restricted rental criteria. more importantly, he was able to find an excellent tenant for us that match our rental property needs. He also efficiently took care of all the various tasks related to the listing process. throughout the whole process, he maintained excellent communication, guidance and advice. We are thankful for his efforts and very happy with the end result.

Leang, Anaheim

"It has been a while since we talked. I am busy with the kitchen remodeling. It was a pleasant to know you and had you as my real estate agent. After seeing many houses and multiple offering without any result, I was almost quit. But with your determination, patient, and persistence, I was able to get that I want. That is not to mention about your professionalism. Thank you and keep up the good work.




Jinno and Suzuki, Orange

"Ethan was our realtor and we had a great experience with him. He is professional, efficient, and very up-to-date with today's market. Not only did he save us so much time, his friendly nature also alleviates a lot of the stress. One of the best qualities we like about him is that he is not a pushy sales person. Ethan did not rush us or try to persuade us into making a buying decision, but was very patient and conscious of our needs. We strongly recommend him.

Martinez, Santa Ana

"I was extremely happy with the entire experience with Coldwell.  I really appreciated that my agent kept me well informed the entire time.  I did not even have to call him once regarding how things were progressing!  Thanks for everything!
