Security deposit is legally capped at two months' rent (Rental Housing Market Development and Regulation Act, Art. 7), and 1-2 months is standard
591 aggregates the overwhelming majority of listings, giving a deep, well-priced long-term market once you navigate the Chinese interface
Among the world's best-rated systems for access and value — No.1 in Numbeo's Health Care Index for 7 straight years (2025, score 86.5) and top of the 2025 CEOWORLD index (score 78.72).
Very low point-of-service costs: NHI clinic copayments are around NT$50, with higher tiered copayments (up to ~NT$420) for unreferred visits to large hospitals to steer minor cases to clinics first.

Watch out for

591, the main portal, is almost entirely in Chinese, creating a language barrier that pushes some foreigners toward pricier English-friendly channels or agents
Some landlords request a local Taiwanese guarantor to co-sign, which can be difficult for new arrivals (though often negotiable, especially via an agency)
Non-employed temporary residents (incl. digital nomads / Gold Card holders without an employer) must complete six months of continuous residence before they can enroll in NHI — one trip abroad under 30 days is allowed, but the count otherwise restarts.
Until NHI enrollment, residents are uninsured for medical bills and should carry private/travel health insurance; major or hospital care can be costly out of pocket.
