Investing in a 3-bedroom apartment in Barranco, Lima
Let me be direct about what the numbers say for a 3-bedroom in Barranco. On a long-term rental you're looking at roughly 5.2% gross yield. That's before management, maintenance, taxes, and vacancy, so treat it as a ceiling, not a take-home figure.
On the Airbnb side I have nothing solid to offer. The short-term data for 3-bed units in Barranco is too thin to call, so I won't pretend a number exists. If someone quotes you a confident nightly rate for this size here, ask them where it comes from.
Because I can't compare the two strategies, I can't tell you which one wins for this apartment. That's an honest gap in the data, not a soft recommendation for one side.
So who does a 5.2% long-term 3-bed suit? Someone who wants a predictable tenant relationship and is comfortable with a modest gross yield in a desirable district, rather than someone chasing short-term upside they can model. If your whole case depends on Airbnb, this isn't the size or district where I can back that up with figures.
None of this is investment advice. Run your own costs and get local tax input before you commit.
