Hi Maria and Jean, Thank you for getting new tenants into Apusento Gardens. That was very quick and greatly appreciated, especially at an increased rent!


Maria, Iris and I want to thank you for the quick sale of our unit. We thought it would drag out for months based on everything that is going on. We appreciate your efforts on our behalf and are glad that you were there to oversee it. Iris and Jim


A big mahalo to you, Maria, for working with us from day one! We appreciate all you've done for us! God was surely in this sale as we just put it in His hands and we had no stress and worries about any of it. Our God is amazing when you let Him do the work! God bless you abundantly and keep you healthy and happy! Aloha
