Foreigners can rent on a passport with the same rights as nationals - no residency or visa status required to sign a lease
Panama uses the US dollar, so rents are quoted in USD with no FX risk or conversion for many nomads
Private hospitals in Panama City are high quality, with two JCI-accredited facilities (Hospital Punta Pacifica, affiliated with Johns Hopkins Medicine International, and Hospital San Fernando) and many US/Europe-trained, English-speaking doctors.
MINSA public clinics and ERs are open to everyone, including foreigners and tourists, at very low cost — a basic public GP visit can be roughly USD 9-11 and a public ER visit around USD 50-100.

Watch out for

The 45-day minimum-stay rule in the District of Panama (Ley 80 de 2012) bans sub-45-day rentals without an ATP tourism-lodging permit; it applies district-wide, including Casco Antiguo, so true short-stay options are limited unless the host holds a permit
Lease contracts are legally valid only in Spanish (the Spanish version controls) - get a reliable translation before signing
A temporary resident or nomad cannot join CSS (the contributory social-insurance fund) — that requires being a formally employed permanent resident who pays into it — so plan to rely on out-of-pocket payment, MINSA public clinics, or private health insurance.
Quality and English-speaking care are concentrated in Panama City; rural public facilities are more basic and may have longer waits and limited English.
