This document covers the property-transaction side of financing a Portuguese home purchase with a mortgage: the loan-to-value (LTV) ceiling that determines how much cash you need beyond the loan, the mandatory bank property valuation (avaliação bancária) that happens during the purchase process, and how mortgage approval timing needs to be coordinated with the CPCV and deed dates. For bank-product details — interest rate types, which banks lend to non-residents, and the loan application paperwork — see the separate banking mortgages document; this page only covers how financing mechanically fits into a property purchase.
Note: Banco de Portugal's own LTV/DSTI/maturity-limits page could not be directly fetched during this research (it returned an access-denied response to automated retrieval); the figures below were confirmed through a web search that itself drew on bportugal.pt content, including the Banco de Portugal report "Acompanhamento das medidas macroprudenciais em Portugal" and related FAQ/communiqué pages. Treat the exact percentage as needing a final human check directly against bportugal.pt before publishing as authoritative.
The LTV ceiling directly determines your minimum cash requirement at closing: it is not just the deposit and closing costs, but also whatever portion of the price the bank will not finance. Because the bank's own valuation (not the agreed purchase price) is what LTV is calculated against, a low bank valuation can force a buyer to bring significantly more cash to the table than expected — and this valuation typically cannot be obtained until financing is already in process, creating a timing dependency with the CPCV deadline.
Key Facts
Banco de Portugal's macroprudential recommendation caps the LTV ratio at a maximum of 90% for loans used to buy or build an owner-occupied permanent residence (habitação própria e permanente).
LTV is calculated on the lower of the purchase price and the bank's own property appraisal (avaliação bancária) — not on the price agreed with the seller. If a buyer agrees to pay €250,000 but the bank's valuation comes in at €230,000, the loan and LTV are based on €230,000, meaning the buyer must cover the €20,000 gap plus the normal down payment out of pocket.
For properties bought for purposes other than a permanent residence (e.g., a second home), banks generally apply a lower LTV ceiling; market reporting places it around 80%, though this specific figure was not independently confirmed against an official Banco de Portugal table during this research and should be treated as indicative rather than confirmed.
Non-resident buyers commonly face more conservative LTV ceilings from individual banks — market/industry sources describe ranges roughly in the 65–75% band even for a would-be primary residence — but this is a matter of individual bank risk policy, not a distinct Banco de Portugal regulatory ceiling for non-residents; it was not verified against an official Banco de Portugal source and should be confirmed bank-by-bank.
The bank's property valuation (avaliação bancária) is a mandatory step in the mortgage process — the bank sends its own certified appraiser (or a firm on its panel) to inspect the property before issuing a binding loan offer.
Steps
Coordinate financing with the CPCV — Because the bank valuation and full loan approval typically cannot be completed instantly, buyers relying on a mortgage should either build a financing contingency clause into the CPCV, or make sure the CPCV deadline for the final deed allows enough time for the bank's valuation, underwriting, and formal loan offer before the deed date. A CPCV signed without a financing contingency exposes the buyer to loss of the deposit if the mortgage falls through before the deed.
Bank valuation (avaliação bancária) — Once a mortgage application is underway, the lending bank commissions its own valuation of the property, independent of any price agreed between buyer and seller. This valuation — not the purchase price — sets the ceiling for how much the bank will lend under the applicable LTV limit.
Final loan offer and deed timing — A binding mortgage offer is normally only issued after the bank valuation is complete. The deed (escritura) cannot be signed until the loan is finalized (if the purchase depends on it), so the deed date in the CPCV should be set with this sequence in mind.
Common Mistakes
Signing a CPCV deed deadline that is too tight for the bank to complete its valuation and underwriting, risking forfeiture of the deposit if financing isn't ready in time.
Assuming the LTV percentage applies to the agreed purchase price rather than to the bank's own (potentially lower) valuation.
Treating the 90% LTV ceiling as available to all buyers uniformly — it is a maximum recommended ceiling for owner-occupied permanent homes, and individual banks can and do apply stricter limits, particularly for non-residents and second homes.
