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.
