Kauai property values are higher than the national average. But resident home ownwers here enjoy the lowest property tax in the USA.
That makes housing much more affordable that the sticker price implies for people moving from higher tax states like California and much of the USA.
Residents also get a home exemption that reduces your tax base, and that exemption increases for seniors to keep it affordable for those on fixed income. (Image courtesy of sscreations at FreeDigitalPhotos.net)
