Air Conditioning: Many houses do not have central A/C and consider the costs of running the A/C because electric is incredibly expensive.
Parking: Many places have crowded parking and different towns have vastly different road conditions.
Pet Deposit: A lot of places don’t accept pets or some of the ones that do will want ridiculous things like additional month’s rent in collateral. Yikes!
Weather: Different parts of the island have widely different weather (look up annual rainfall, etc)
Jalousie windows: This is something I wished I learned about before I moved in. They are great for letting air in but if you want to run an A/C a lot of the older windows have large gaps in between when you close them.
Appliances/Utilities: So I’ve noticed many homeowners will say ‘The rent covers utilities’ especially if they have solar panels. Keep in mind what your likely costs of utilities might be with the cite listed here and if the homeowner wants to regulate your electricity usage.
Garage/storage spaces: Most of the homes we looked at had park ports with an outdoor storage closet.
Location: Considering children there are a few websites like Family WatchDog for crime. For education, there is SchoolDigger to find schools and Hawaii DOE to find what school district they would be placed in if you choose a certain neighborhood. Also, think about the proximity to work and traffic hours.
If you rental shares walls or you live on the same property as the homeowner: I know this sounds odd to most people but places like Haleiwa do have large places but the only drawback is your property owner might be a little too close for comfort.
Home Owner Associations: This is pretty important for my husband and I, the nicer parts of town typically don’t let you have cars on jack stands if leave tools out and for good reason! But the good thing is a lot of the associations have benefits like access to the YCMAs in the area (if your property owner will pass that info to you).
Closet/room space: I’ve found many homes had little to no closet space even in the master bedroom.
