Thanks @Dede Christensen for the article. Definitely an interesting bill for Hawaii where education is not funded by property taxes.
As a quick side note, Hawaii teachers are not paid enough. They could make $80k and still not be paid enough. Anyone who has chaperoned on a school field trip could attest! :) God bless teachers!
Without getting too political, and to keep it brief, I do not think the bill will make it out of the subsequent committees. Hawaii can be a funny place some times. The teachers union and education in general often get some pretty raw deals from the legislature here.
Now to real estate. Should the bill pass as is, you are right, the implications on residential real estate could be significant. With current property prices and a threshold of $500k for the tax hikes, the majority of properties could be effected.
I think two things could save us (in Honolulu/Oahu). First, a large portion of condos are still below the $500k mark and would remain unaffected. Second, the bill states "residential" properties, which may allow for a loophole for multi-unit properties of 5+ units, which could be categorized as commercial properties. Should these two items be true, then the large majority of the properties being effected would be single family homes.
From my experience, most people here renting out a single family home have a significant amount of equity and/or purchased years ago, meaning their monthly expenses are low enough, that they could (although they wouldn't want to) absorb this tax increase. Let's assume I am totally wrong about SFH owners. Then those owners renting out a SFH may choose to sell due to the increased taxes, but these homes would be picked up quickly by owner occupants, due to the absurdly low housing supply. Allowing prices to remain fairly unchanged.
Overall, I am bullish on the issue, but definitely something to keep an eye on! Maybe I will change my tune depending on how the bill progresses through the other committees.
