How Rendio works

The same listing on Idealista, read for what actually matters to a buy-to-let investor — net yield after real costs, price against real comparables, and the legal and tenancy risks the description quietly carries.

Three steps from listing to decision

1. Every new listing, in one place

Each morning Rendio pulls the day's new listings from Idealista across Spain's major cities. You don't keep refreshing — you open Rendio once.

2. Analyzed against real numbers

For every listing, we compute the net yield against real local rents and full ownership costs — ITP, notary, registry, community fees, IBI, vacancy, maintenance. We compare the asking price to actual nearby sold-and-asking comparables. We surface days on market and price drops. One 0–100 score summarizes the deal.

3. The decision-ready ones rise

Sorted by score, the deals worth your hour come to the top. Dealbreakers — VPO, sitting tenants, energy band — are stamped on the card so you skip the ones that don't fit. You spend your time on the 10 you'd actually buy, not the 200 you'd reject.

What you see on every listing

A deal score that means something

0–100, calibrated against five components: cashflow, yield, expected appreciation, total return, and risk. The breakdown is on the page — no opaque box.

Net yield, not gross

Real net yield, computed against real local rents and the actual cost stack of owning the property in Spain. Not the inflated gross figure portals quote.

Price against the neighborhood

How this listing's €/m² compares to recent sold and asking prices on the same streets, with the number of comparables behind the comparison.

Dealbreakers up front

VPO, sitting tenant, illegal occupation, structural reform pending, derramas (pending building works) — surfaced before you click, not after you've spent an afternoon.

We read the fine print

Most risks hide in the description, not the data fields. Rendio reads every listing and flags the verbatim phrase that gave it away — so you skip the trap before you waste an afternoon.

What Rendio doesn't do

Not financial advice

We surface the evidence in one place. The decision — and the offer — is yours.

We don't list properties

Rendio reads the listings that already exist on the major Spanish portals. We don't represent sellers and we don't take commission on a sale.

We don't replace a notary

Once a deal is on your shortlist, the conveyancing checks — title, charges, tenancy — go through your notary and lawyer. We help you not waste that step on the wrong listing.
