Most listing sites tell you the asking price. IQRend tells you whether to pay it. The product reads the listing, runs the same calculations a Paris-trained property analyst would run on a yellow pad, and writes the verdict in a sentence.

Section 01 · Method

01

The six questions, answered.

Every analysis returns a verdict that sits on these six pillars. No upside framing, no urgency copy, no rush to buy.

  1. 01

    Is this property a good investment?

    The 0–10 IQRend score weighs yield, cash flow, payment-to-rent ratio, and market-price gap. Above 7.5 is a buy; below 4.5 is a walk-away. Anything in between gets a written reason.

  2. 02

    What's the cash flow?

    Monthly cash flow after mortgage, taxes, insurance, vacancy, and maintenance. The number you actually keep, not the gross rent.

  3. 03

    Is the market overheating?

    Asking price compared against the rolling 24-month median €/m² for the precinct, with confidence bands when comps are sparse.

  4. 04

    What are the risks?

    Eight flag codes from the same engine that runs the score: thin DSCR, single rental comp, rent control, age of roof, deferred maintenance. Always shown above the verdict.

  5. 05

    Long-term, Airbnb, flip, or avoid?

    Each strategy is scored separately and the best one is named. Tax regime is read from the country, not assumed.

  6. 06

    How does it compare?

    Three nearby comps and the same money in a broad-market ETF, side by side, over the same 10-year horizon.
