Testimonials
Recommended!! (10stars)‘ We met Owen 5 months ago. Owen was very friendly ,professional and easy going agent and he helped us to get our dream home. We've been looking for 4 years and we have been unsuccessful because we didn't know what's the process was. Ever since we've met Owen, he helped us from the very beginning. We've described to him what we wanted and he sent us a lot of options to look at. PLUS he is always willing to go the extra mile for his clients. We've had a private viewing at 11pm just to see the house as my mom normally finishes work at 11 and he never once complained nor had a second thought of helping us to do a private viewing on the middle of the night. We highly recommend Owen.- Jessa May Agac-ac
Excellent job!!! Owen is very professional, He knows the market very well and always put an extra mile to his clients. It only took us about 3 weeks to find our HOME. My family and I are very thankful to Owen. We highly recommend him to anyone who is looking for a home specifically to the first home buyers.- AJ & Jaine Plaza
He is professional, helpful, and a good person. Very organized and strategetic in marketing. He is a good agent and helpful. He didn't stop helping me until the end of my transaction. Thank you for your help and I will see you at my next purchase.- Johnny Sotelo
Anytime! Anywhere!˜Š The moment you contact Owen, day time or night time, he will respond and look after you. I asked him if we can view the property at around 9pm and he made it happen on a very short period of time. At 10pm a decision was made, we will join the auction the next day. And we WON! Thank you so much Owen for your assistance on our purchase. Great service indeed! 10/10 agent.- Elizabeth Presquito
