 The UHERO study also estimates that 4,000 Maui residents have moved from the island since the fire. That's in large part because of the lack of available and affordable housing. Hawaii's rent is the most expensive in the country, and Maui's is now the priciest in the state. Median rent on the island has gone up 40 percent this year over last year. In West Maui, nearly 50 percent of housing is short-term rentals, while only 34 percent is residential units.
