Real references of the same municipality and type, to cross-check rent and price. They are not necessarily active offers.

This is a shortlisting pass over the advert's data, not a due diligence report. Before deciding, check the points we cannot verify from here:

  • Possession: that it is vacant, with no squatters and no tenants on a live contract.
  • If it is let, the current rent, the type of contract and its expiry date.
  • The real state of repair and services (possible hidden renovation work) and a valid energy certificate.
  • The real service charge and, above all, whether any special levies are approved or pending: they appear in the minutes of the last owners' meetings.
  • The property's actual IBI: our figure is an estimate from the municipality's cadastral values, not the specific bill.
  • Charges, mortgages, seizures or easements in the Land Registry extract.
