I-Hsiang Tsai, came to Hawaii when he was 13 years old, after many years of endeavors, he got his medical degree in Hawaii. However, instead of going into practicing medicine he started his own business path, started his own company, and initiated different projects internationally. He was a consultant to a public traded medical company in Taiwan and assisted many business entities in different deals in the past. In 2013, he received his Hawaii state real estate license because many of his business ties had the need for real estate investment. Although not currently practicing medicine, he shows his compassionate nature in his real estate work as well. He understands how important it is for a family to have a home. He helped many first-time home buyers and military buyers to get their first homes in Hawaii. With his language ability, he professionally assisted many international investors in getting their first Hawaii investment. With his business background and marketing experience in the past, he extends his marketing reach to many Asia countries. He set up a website mainly tailor to Asia clients and by doing so he is able to not only help the investors but also local sellers who would like to market their homes to both local and international buyers. So far, his success rate is close to 100% and has earned a 5-star rating on the Zillow website as well. Many client’s reviews do reveal that he is a responsible and reliable professional that you and your loved one can rely on.

" I think Rex is a realtor who is standing on your side. He is not the one who just wants to make the sale. He helped me so much when I was in a rush to find a place. He went to open house with me even when there was a storm. And he is an expert in negotiation as well. And he even reminded me to schedule with the electric company to turn on the electricity. I am looking forward to working with Rex again. "

Mr. Guo Honolulu, HI


" Rex is a consummate real estate professional. He listens, pays attention to my preference and our conversation. He actively solicits feedback from me without being pushy and assisted me in narrowing down my condo search. At stressful moments, he brings back laughter, joy, and calmness to cheer me on my condo purchase process. I would definitely recommend him and will engage him should I be looking for another piece of real estate. "

Bernard Tan Honolulu


The great home buying experience with Rex! Responsive, diligent, professional. Highly recommend Rex provide me good advice to do a 1031 exchange which provided me tax deferral benefits. It was a last-minute decision and he was able to get it all organized on time to meet the seller's schedule. It was a tenant-occupied unit that I was doing the exchange for and Rex managed the tenant relationship nicely. He provided me with many helpful pieces of advice and insights during the process. Really appreciate it"

Tony Wong


"Rex is very helpful. He is a “master” in creating strategies for our offer to be accepted. He is responsive to all questions and stays up all night to assist. He is a realtor that can be trusted. Very comfortable to work with, it’s like working with a friend. Very knowledgeable. The best realtor in town!"

Sheir Casandra Devera


Dr. Tsai provided me with outstanding service, particularly in those unprecedented times during the COVID-19 crisis. He provided me detailed and timely help and instructions during the transaction. His service really goes "above and beyond" my expectations of a REALTOR®'s role. It was my honor to nominate Dr. Tsai for the Honolulu Board of REALTORS® 2021 Aloha ‘Āina REALTOR® Awards.
