Before pricing finishes, check legality, planning, structure, moisture, energy, access, contractor, timing and financial contingency.
Key takeaways
- Check legality and planning before finishes.
- Inspect and budget by risk.
- Never assume an ARU benefit.
Start with legality, planning and building condition—not finishes. An older property may combine character with undocumented alterations, planning restrictions, moisture, structural issues and an incomplete budget.
Five checks before the final price
- Compare the land registry, tax record, use documentation, approved plans, energy certificate, boundaries, access and visible annexes.
- Consult current territorial plans. The DGT’s official SNIT provides written and mapped planning instruments, but confirm the specific proposal with the municipality.
- Ask a qualified architect or technician to identify the likely procedure, external opinions, unknowns and realistic sequence.
- Commission a risk-led inspection covering structure, roof, moisture, timber, drainage, electrical installation, water, ventilation, energy and site access.
- Build a layered budget: acquisition, surveys, design, regularisation, structure, envelope, services, interiors, external works, temporary housing and contingency.
For existing buildings, the DGEG explains that the energy certificate includes economically viable improvement measures. Use it as an initial diagnostic, not as a renovation design.
In Alcobaça, check the current PDM and whether the property lies in a published urban rehabilitation area. ARU status does not make tax support automatic; confirm boundaries, initial and final inspections, certification and recognition before relying on an incentive.
Verify the contractor’s licence or certificate through IMPIC and compare proposals using the same scope. If purchase depends on feasibility, inspection, regularisation or works finance, have those dependencies written into the CPCV with legal review.
Stop and investigate mismatched areas, unexplained cracks or moisture, missing plans, unrealistic approval assumptions, incomplete structural budgets or reliance on an unconfirmed tax benefit.
The 2026 planning update: three separate checks
Under RJUE article 4-A(14), amended by Decree-Law 108/2026, with its July correction, the transfer document must identify a presented planning title or record the seller’s declaration that they hold it without presenting it, or do not hold it; omitting the statement can make the transaction voidable. A seller’s declaration does not legalise building work or certify use.
Separate purchase formalities, lawfulness of the existing building and permission for future work. Obtain municipal records, compare approved plans to reality and commission a qualified feasibility assessment. Exemption from prior licensing is not exemption from applicable building rules or proof that an extension is allowed. Check the current Alcobaça PDM and the parcel’s municipal ARU boundary; ARU location alone confirms no tax entitlement.
Fictional budget exercise, not market quotes: works €40,000; surveys/design/supervision €8,000; temporary accommodation and indirect costs €6,000; contingency €8,000. Total €62,000 before acquisition, taxes and credit. This is not a recommended contingency percentage. Mark VAT treatment, exclusions, payment stages and supporting quote for each item; replace the figures with comparable quotes and risk-specific reserves. Before offering, request written feasibility and a total-cost range.
