Valuation

Three questions Valuation must answer

In Portugal there is no broad seller disclosure regime. Sellers are not obliged to highlight illegal extensions, rising damp behind fresh paint, or roof and structure works that will fall due shortly. Once you sign the CPCV, those problems become yours. Valuation exists to surface price, renovation, and structural risks while you still have room to negotiate or walk away.

• 1. Is the asking price real or inflated? Smart Valuation compares the listing against recent SIR transactions in the same building, street, and neighbourhood so you see a realistic price band—not just the seller's number.
• 2. What will renovation really cost? Renovation Scanner translates "needs work" into numbers, from cosmetic refresh to structural overhaul, so you can budget total cost (purchase + works) instead of guessing.
• 3. Are there hidden structural or legal problems? Technical Deep-Dive coordinates independent engineers to check the fabric of the building and Simplex risks before you commit at CPCV.

What happens if you skip valuation

Imagine a "recently renovated" apartment in Graça. The finishes look great, the agent says the works were done "professionally," and the price feels high but justified for the views. You agree a price based mainly on the asking number and sign the CPCV.

Six months after deed, damp stains appear on two walls. An electrician explains the wiring is decades old, not part of the recent refurbishment. A plumber finds original galvanized pipes that now need replacing. The "renovation" turns out to have been cosmetic—paint and finishes over unresolved technical issues.

Between hidden defects and corrective works, your true cost ends up far above what similar apartments in the same area are selling for. With a structured valuation approach—Smart Valuation for price, Renovation Scanner for works, and a Technical Deep-Dive where needed—you would have seen the likely value range, budgeted realistic renovation costs, and had evidence to either renegotiate or move on to a better property.

What you get from Valuation

This phase answers: Is the asking price fair? What will renovation cost? Are there structural or legal red flags? In a "Simplex Urbanístico" environment, more due diligence falls on the buyer.

• A realistic price band (not just listing price)
• Estimated renovation cost by tier (cosmetic to structural)
• Flags for structural or legal issues before you commit at CPCV

Structural risks in Lisbon's building stock

Lisbon has a mix of historic and mid-century buildings. Two common risk areas:

• Gaiola Pombalina (post-1755): Timber frames inside masonry walls absorb seismic loads. Unauthorised removal of timber diagonals for open-plan layouts can compromise earthquake resistance. A structural check should confirm the cage is intact.
• Lusa slab / early reinforced concrete: Carbonation and "concrete rot" (oxidising reinforcement that cracks concrete) are common in mid-20th-century builds. Inspectors can flag these before you proceed.

Simplex Urbanístico and "zero licensing"

Under recent reforms, many interior works no longer require municipal approval, and sellers are often not required to hand over a usage licence at the deed. That can mean you are buying a property with unregularised additions or alterations. Cross-check the Caderneta Predial (tax record) and Certidão de Teor (land registry) with the physical property: any mismatch in area or room count should be treated as a "Simplex risk" and verified with a professional before you sign a CPCV.

Renovation costs (2026 Lisbon–Cascais–Sintra)

Renovation budgets depend on scope. In 2026, reduced VAT (6%) can apply to qualifying rehabilitation in ARU (Urban Rehabilitation Areas)—our tools can help you check ARU status for a given property.

Tools for Valuation

Most buyers follow a three-step path: first, run a Smart Valuation to see if the asking price sits within a sensible range; second, use the Renovation Scanner to understand what "needs work" really costs; and third, order a Technical Deep-Dive where the building age or condition calls for independent engineers.
