A recent single month's median sale price ran $1.1 million; Q2 2026 alone saw single-family homes trade at a $2,350,000 median -- multiples of the roughly $355,000-$375,000 range commonly cited nationally in 2026 (base record).
A real, structural long-term-rental scarcity
Vacation-rental investors compete directly with long-term renters and primary-residence buyers in the Poipu/Koloa corridor, pushing rents up and shrinking available long-term inventory (base record).
