Underwriting a Portuguese residential development

Portugal licensed 42,048 homes and completed 26,714

Those two figures, both from 2025, describe the Portuguese development opportunity and the problem with it in a single comparison.

Licensing rose 21.4% year on year. Completions rose 5.5%. The gap is not a planning failure — it is a funding failure. Projects are being approved faster than they are being financed and built, in a country with a structural housing shortfall and a domestic institutional equity market too shallow to close it.

That is why foreign capital is being offered Portuguese development equity, and why most of what is offered will not perform as presented.

What follows is a practical framework for underwriting a Portuguese residential scheme: the costs that are understated, the risks that are binary rather than scheduled, and the exit assumptions that most sponsor models get wrong.

The five variables

Every residential development model in Portugal reduces to five things. Land, construction cost, soft costs and time, finance, and exit value. Four of them are routinely underestimated by foreign investors and one is routinely overestimated.

1. Land, and whether you can actually build on it

Entitlement risk in Portugal is binary, not a schedule variable. This is the single most common analytical error made by investors arriving from markets where planning is a matter of negotiation and timing.

Portuguese land is classified urbano or rústico. Rustic land does not carry residential development rights as a matter of course. The National Ecological Reserve and National Agricultural Reserve — REN and RAN — overlay large areas independently of the municipal plan and can prohibit construction on land that appears clear under every other instrument. Natural park designations, coastal programs, and heritage protections each apply on their own terms.

A parcel can be permitted under one framework and blocked under three others.

What to require: written viability confirmation from the relevant câmara municipal for the specific parcel, plus REN, RAN, and any protected-area boundary checks. Where a sponsor presents land without a licence or an approved project, the appropriate treatment is not a discount — it is exclusion from the base case entirely, with any residual value assigned to an upside scenario.

Land with an approved project and a paid construction licence is a materially different asset, priced accordingly, and the premium is usually justified. Two checks remain: whether the licence is within its validity period, and whether the approved scheme is the product you intend to build, since amending an approved design can reopen the approval process.

2. Construction cost, and the quote that is not the cost

Current Portuguese construction costs for 2026:

And now the trap. Portuguese contractor proposals routinely quote the construction cost only. The total cost of a scheme delivered ready to occupy commonly runs 25% to 40% higher.

A published worked example for an 830 square meter residential building puts construction at €913,000 — roughly €1,100 per square meter — and the total cost excluding land at approximately €1,351,000, or €1,628 per square meter. That is a 48% gap between the contractor’s number and the real one.

What sits in the difference: external works and site preparation, utility connections, elevators, technical installations beyond the base specification, landscaping, common area finishes, contingency, and the items a contractor excludes as “client supply.”

An underwriting model built on a contractor quote is understating cost by a quarter to a half. Demand the full development budget, not the construction tender.

Cost inflation is live. Construction costs for new housing rose 6.9% year on year in May 2026, with materials up 6.4%. A model built on 2024 figures is already wrong.

3. VAT, and the clawback that sits on your exit

Decree-Law No. 97/2026 cut VAT on qualifying residential construction and rehabilitation works from 23% to 6% — a seventeen-point reduction on the construction contract.

This matters more than it appears, because Portuguese residential property transfers are generally VAT-exempt without the right to deduct input tax. A developer building housing for sale cannot ordinarily recover VAT charged on construction. It is an absorbed cost, not a timing item.

On a €5 million construction contract, the reduction saves €850,000.

The conditions are strict and they constrain your exit. For the owner-occupier route, property value may not exceed €660,982 and the sale must complete within 24 months of the utilisation licence. For the letting route, rents may not exceed €2,300 monthly and the property must remain let for at least 36 months within the first five years.

If the conditions are not met, the seventeen-point difference becomes payable.

For an underwriting model this is a contingent liability sitting on the exit, and it must be modelled as one. A scheme that applies 6% during construction and then sells above the threshold, or to investors rather than owner-occupiers, or outside the 24-month window, faces a retrospective VAT charge on the entire construction contract.

Two practical consequences. The benefit limits who you can sell to and at what price. And the letting route commits capital for three years of operation beyond completion, which converts a development return into development-plus-hold.

A separate provision allows restitution of 50% of VAT on architecture, project design, and studies. The measures run to 31 December 2029, with transitional application to licensing procedures commenced from 25 September 2025 — which makes the licensing commencement date on any acquired pipeline a diligence item with direct margin consequence.

4. Soft costs and time

Professional fees. Architecture plus specialist engineering typically runs 3% to 6% of construction cost. Municipal licensing fees for a single house sit around €2,500 to €6,000; larger schemes scale accordingly.

The realistic timeline for new construction:

Preliminary study and project: 2 to 4 months.
Licensing: 2 to 6 months, varying substantially by municipality and complexity.
Construction: 12 to 24 months.
Total: 18 to 36 months from start to delivery.

Add acquisition, marketing, and sale and most schemes run three to four years from capital commitment to full exit.

Licensing deserves separate treatment. The OECD identifies permitting delay as a primary constraint on Portuguese housing supply, alongside construction costs, skill shortages, and regulatory burden. Municipal processing times vary widely and are difficult to predict from outside.

Model licensing as a risk, not a date. Where approval is not yet in hand, construction should not be underwritten to start on an assumed date, and the capital should not be assumed deployed on that basis.

5. Contractor risk

Underweighted by almost every foreign investor, and the failure mode that destroys development equity fastest.

The Portuguese construction sector carries an estimated labour shortage exceeding 90,000 workers. That produces three effects: contractor pricing power, extended programmes, and — most consequentially — contractors taking on more work than they can deliver.

Contractor insolvency mid-project leaves a part-built scheme, a performance dispute, a re-tender at current prices, and months of lost time. It is the single largest execution risk in Portuguese development and it is not reflected in any sponsor model.

What to require: the contractor’s audited accounts, their current order book, performance bonds or retention, a fixed-price contract where obtainable, and a genuine plan for what happens if they fail. A sponsor who has not thought about this has not developed before, or has been fortunate.

Finance

The rate environment turned. The ECB raised its key rates in June 2026, the first increase since September 2023, with Euribor rising across the curve. Development finance models built on 2024 assumptions need rebuilding.

Corporate acquisition and development finance sits outside the consumer lending framework. Banco de Portugal’s Macroprudential Recommendation No. 1/2026, which cut the maximum debt-service ratio to 45%, governs credit to consumers. Development lending is a bank credit decision rather than a regulated one — which widens what is negotiable and narrows what is predictable.

Model the funding cost on the drawn profile, not on the facility size, and stress the interest line against a further 100 basis points.

Exit: where models break

The optimistic variable, and the one requiring the most discipline.

Price evidence. Median bank appraisal values reached €2,174 per square meter nationally in April 2026, with apartments at €2,546. Lisbon’s city-wide average sits near €5,900, prime Lisbon between €8,000 and €10,300, and prime new build on Avenida da Liberdade, Chiado, and Príncipe Real reaching €12,000. Porto stands near €4,053, Braga €2,240, Guimarães €2,108.

Underwrite exit values on comparable evidence of achieved prices, not on asking indices. Portuguese asking prices consistently exceed transaction prices, and achieved prices in the Algarve typically settle 6% to 9% below final asking.

Do not underwrite continued price growth. Prices rose 17.6% in 2025 and 19.8% in the first quarter of 2026. Those are exceptional figures and projecting them forward three years is not underwriting, it is hoping. The defensible base case holds values flat from the current comparable evidence, with growth as upside.

Model the sale period, not the sale date. Well-priced apartments in Lisbon, Porto, Braga, Aveiro, and Faro have cleared in 45 to 75 days. Ordinary resale nationally runs 90 to 120 days. Anything mispriced sits past 150. A twelve-unit scheme does not sell in a month, and the sales curve drives the finance cost.

And the buyer-pool question, which is new. From September 2026, buyers who are not Portuguese tax residents pay a flat 7.5% IMT with no exemptions. If your exit depends on international non-resident purchasers, their total acquisition cost just rose by several points — and that is absorbed somewhere, usually in the price they will pay. Purchases by foreign families resident outside Portugal already fell 14.1% in 2025 while the overall market set records.

Identify the realistic buyer for your product before committing, and model the exit against that buyer’s position rather than against the market generally.

The returns question

Sponsors in this market typically present development IRRs in the high teens to mid-twenties with equity multiples of 1.5x to 2.0x over three to five years.

Those are targets, and they are highly sensitive to the five variables above. The sensitivities that matter most, in order:

Construction cost, because of the quote-versus-total gap and live inflation.
Timeline, because every month of delay carries finance cost and erodes IRR regardless of profit.
Exit value, because a model built on continued appreciation is a leveraged bet on a market that rose 19.8% in a quarter.
VAT clawback, if the 6% rate is applied and the exit conditions are not met.
Contractor failure, which is low probability and high severity.

Rebuild the model independently on conservative inputs: full development budget rather than construction tender, flat exit values, licensing unresolved treated as unresolved, and a realistic sales curve. If the project still works, it is worth considering. If it only works at the sponsor’s assumptions, you are being asked to fund their optimism.

What to require from a sponsor

Full development budget, line by line, not the construction tender.

Written municipal viability or the licence itself, with its validity period.

Contractor identity, accounts, and order book, plus the performance security and the contingency plan.

Comparable evidence of achieved prices for genuinely similar completed product in the same location.

The VAT position in writing from Portuguese tax counsel, including the clawback exposure under each exit scenario.

Track record to full liquidation, not to launch. A sponsor with three schemes started and none exited has no track record.

Co-investment in cash, as a figure, and whether it is cash or a fee waiver.

Information rights and reserved matters negotiated explicitly. Portuguese sponsors are frequently less institutional in reporting and governance than a European or North American investor expects, and this should be addressed in documentation rather than assumed.

The case, stated fairly

The opportunity is real and it is structural. Portugal needs roughly 70,000 homes a year and is delivering 20,000 to 28,000. Licensing is running 21% ahead of completions. Bank leverage has tightened and the domestic institutional equity base is shallow. The state has improved development economics with a seventeen-point VAT reduction and long-duration rental incentives.

The constraint is execution, not demand. Projects fail here on licensing, on cost, on contractors, and on exits modelled against the wrong buyer — not on an absence of people who need housing.

Capital that underwrites properly and accepts a three-to-four-year horizon has a genuine opportunity. Capital that accepts a sponsor’s model is funding someone else’s assumptions.

Underwriting support, independently. Independent review of the development budget against current cost evidence, the licensing position with the municipality, comparable achieved prices for the specific product and location, and the exit buyer pool — alongside Portuguese technical and legal partners.

Sponsor and contractor assessment. Track record to liquidation, co-investment level, delivery history, and what has gone wrong before and how it was handled. In a market with few institutional-standard counterparties, the counterparty is a larger share of total risk than the asset.

Origination against a defined mandate. Development opportunities and land positions in markets where a substantial share never reaches a public process, filtered against an investor’s sector, size, and return parameters.

Structuring coordination. The VAT position, the acquisition structure, and the holding vehicle settled with Portuguese tax and legal partners before heads of terms — and alongside an investor’s own counsel in their home jurisdiction.

FAQ

How much does residential construction cost in Portugal in 2026?
Between €850 and €1,100 per square meter for economy finish, €1,100 to €1,400 for medium, €1,400 to €1,700 for medium-high, €1,700 to €2,200 for premium, and above €2,200 for luxury. Multi-unit residential buildings at mid-range specification run €950 to €1,500 per square meter. Algarve turnkey villas run €2,000 to €2,800. Construction costs rose 6.9% year on year in May 2026.

Why do construction quotes understate the real cost?
Because Portuguese contractor proposals commonly cover the construction contract only. The total cost of a scheme delivered ready to occupy typically runs 25% to 40% higher, covering site preparation, utility connections, elevators, technical installations, landscaping, common areas, contingency, and client-supply items. One published example shows €1,100 per square meter in construction becoming €1,628 all-in.

How long does a residential development take in Portugal?
Preliminary study and project 2 to 4 months, licensing 2 to 6 months depending on municipality and complexity, and construction 12 to 24 months — a realistic total of 18 to 36 months. Adding acquisition, marketing, and sale, most schemes run three to four years from capital commitment to full exit.

What is the biggest risk in Portuguese development?
Entitlement, then execution. Land classification and planning permission are binary rather than schedule variables, since rustic classification, REN and RAN overlays, and protected-area designations can each independently prohibit construction. After that, contractor insolvency is the failure mode that destroys development equity fastest, in a sector carrying an estimated shortage of over 90,000 workers.

How does the 6% construction VAT rate work?
Decree-Law No. 97/2026 reduced VAT on qualifying residential construction and rehabilitation from 23% to 6%. Because Portuguese residential property transfers are generally VAT-exempt without deduction rights, this is a real cost saving rather than a timing item. Conditions apply: property value up to €660,982 for the owner-occupier route with sale within 24 months of the utilisation licence, or rents up to €2,300 monthly with a 36-month letting requirement.

What happens if the VAT conditions are not met?
The seventeen-point difference becomes payable. For an underwriting model this is a contingent liability on the exit, and it constrains both the price and the buyer type. A scheme applying 6% during construction and then selling above the threshold or to investors rather than owner-occupiers faces a retrospective charge on the full construction contract.

What exit values should a development model assume?
Comparable evidence of achieved prices for genuinely similar completed product in the same location, held flat as the base case. Portuguese asking prices consistently exceed transaction prices, and achieved prices in the Algarve typically settle 6% to 9% below final asking. Prices rose 17.6% in 2025 and 19.8% in the first quarter of 2026, and projecting that forward is not underwriting.

Does the new IMT rate affect development exits?
Potentially, yes. From September 2026, buyers who are not Portuguese tax residents pay a flat 7.5% IMT with no exemptions. Where an exit depends on international non-resident purchasers, their total acquisition cost has risen and that is usually absorbed in price. Purchases by foreign families resident abroad fell 14.1% in 2025.

What returns do Portuguese development sponsors present?
Typically IRRs in the high teens to mid-twenties with equity multiples of 1.5x to 2.0x over three to five years. These are targets rather than outcomes and are highly sensitive to construction cost, timeline, exit value, VAT clawback exposure, and contractor performance. Independent modelling on conservative inputs is essential.

Why is there a development opportunity in Portugal at all?
Portugal licensed 42,048 dwellings in 2025, up 21.4%, against 26,714 completions, up 5.5%. The country needs roughly 70,000 homes annually and delivers 20,000 to 28,000. Bank leverage tightened when the ECB raised rates in June 2026, and the domestic institutional equity base is shallow. Approved projects exceed the capital available to build them.
