Calculating expenses in the Oahu area

[Trevor Yasunaga]

Hi BiggerPockets community! I'm an up and coming real estate investor looking to begin real estate investing as soon as I am able. However, before I start investing actual money, I would like to get a feel of what the market in Oahu is. I wanted to practice analyzing deals with some simulations prior to putting actual money down. I had a question concerning typical expenses on Oahu (Honolulu especially). Such expenses such as electric, water, sewer, gas, vacancies, etc.) Do these expenses change from zipcode to zipcode, the type of services you request, or is it a pretty constant number all around?? Thank you for your help!
