At first glance, Medical Properties Trust (NYSE:MPW) seems like an undervalued dividend pick. It owns and leases 420 hospitals/clinics under "triple-net" contracts that pass all property-related costs (and responsibilities) to its 54 tenants, allowing it to run an impressive $18.3 billion portfolio with only 131 employees. As a REIT, it distributes most of its income to shareholders, making it a rent conduit that links "economy-proof" hospitals to income-oriented investors.
