Barranco edges San Isidro on long-term net yield, about 4.7% against roughly 4.4%, and that is the whole of the case for it. A gap of near 0.3 points is not a reason to buy anything. If you are the foreign buyer this page is written for, you are not choosing between two returns here; you are choosing between two buildings, and the yield will not tell you which.
What you pay to get in is close to a wash. Barranco's median sits at about $2,545 per m2, San Isidro's at roughly $2,510 — San Isidro is about 0.2% cheaper, which is about $4 per m2. On a 70 m2 flat that is a rounding error, not a strategy. Do not let anyone sell you San Isidro on price.
The long-term figure is net: it subtracts property tax, arbitrios, rental income tax and a 3% vacancy allowance. It does not subtract mantenimiento, because in a Lima long-term let the tenant pays that, not you. The owner self-manages on both sides, so no management fee comes off either number — and the model does not subtract furnishing or fit-out, cleaning or turnover, so do not treat those as already paid for.
Airbnb is where the two actually separate. Gross, Barranco runs about 6.2% against San Isidro's roughly 7.2%. The Airbnb figure subtracts the platform fee, host-paid utilities and internet, income tax, mantenimiento, property tax and arbitrios — and the host pays mantenimiento here, with no guest reimbursing it. That is a full point in San Isidro's favour before you have done a single check-in.
So: San Isidro, on the short-let upside and on liquidity, with the honest caveat that the long-term yields are too close to call and the price difference is trivial. Barranco is the pick only if you want the tenant and the quieter building. Either way you are self-managing, and the data here is thin enough that I would not stake a mortgage on the decimal places. Not investment advice.
