Selling in Cascais, step by step
- The online estimate. The likely market value, the recommended asking price and the likely agreed price, from the INE medians for your parish.
- The free on-site market study. Tagus Property visits the property and carries out the market study: what the estimate cannot see (the real light, the building, the street) goes into the price.
- The documents. Gathered before the property goes on the market, they avoid delays at the deed (list below).
- The brokerage agreement. Always in writing, with the agreed price, commission and term (Law 15/2013).
- Listing, viewings and negotiation. Until an offer is accepted.
- Promissory contract and deed. With the buyer's mortgage, if there is one, and the bank appraisal ordered by their bank.
Documents for selling
- Caderneta predial urbana (the land tax register extract), from the Portal das Finanças: it identifies the property and its tax value (VPT).
- Certidão permanente do registo predial, the land registry certificate: it shows who the owner is and whether there are mortgages, attachments or other charges.
- Energy certificate (certificado energético), issued by a qualified assessor in the ADENE system: required as soon as the property is advertised for sale.
- Autorização de utilização (the former licença de utilização, the occupancy permit), from the câmara municipal: since 2024 it no longer has to be shown at the deed of sale (Decreto-Lei n.º 10/2024), but the buyer or their bank may ask for it.
- Ficha técnica da habitação, for more recent buildings: it has not been required at the deed since 2024 either, but the buyer may ask for it.
An inheritance, a divorce, a tenanted property or unlicensed works change the list: have a lawyer or solicitador check the documents for your case before the promissory contract (contrato-promessa).
Online estimate or bank appraisal
The Tagus Valor online estimate is automated and free: a statistical estimate from INE data, adjusted to the property, so that you decide with figures in hand. A bank appraisal is carried out by a valuer registered with the CMVM, at the request of the buyer's bank when there is a mortgage, and sets the loan amount; it can come in below the agreed price.
Only a registered valuer can produce a valuation within the meaning of Law 153/2015: the estimate is not one and does not replace one. It is the starting point for setting the asking price and for talking to whoever will handle the sale.
