I’m assessing a 3-bed country home in Rio de Janeiro priced at R$6,300,000, with expected rent of R$28,180 per month. That supports the advertised gross yield of roughly 5.4%, but gross is doing a lot of work here. My model allows for vacancy, management, routine maintenance and a larger-repair reserve. The building appears sound, while insurance costs and possible rental-regulation changes concern me. Which local expense am I most likely understating, and how much net return would make the risk worthwhile?
