Portugal Real Estate Investment Glossary.

The property's annual net operating income (NOI) divided by its purchase price, expressed as a percentage. It measures the property's return independent of how it is financed — making it the standard metric for comparing investments across different capital structures.

Formula: Cap rate = NOI / Purchase price × 100

In Portugal: above 6% is strong; 4–6% is average for Lisbon; below 4% is typical for premium zones where capital appreciation compensates for thin income yield.

Portuguese: Taxa de capitalização — Cap rate calculator →

Annual pre-tax cash flow divided by total capital invested (down payment + all acquisition costs including IMT, IS, legal fees, renovation). The most honest measure of investment performance — it accounts for financing costs and actual capital deployed, not just property price.

Formula: Cash-on-cash = Annual cash flow / Capital invested × 100

A leveraged buy-to-let in Portugal in 2026 typically generates 1–4% cash-on-cash pre-tax. After IRS at 28% on net rental income for non-residents, this can fall close to zero on many deals.

Portuguese: Retorno sobre capital investido

The Portuguese promissory purchase contract — signed after an offer is verbally accepted, before the final deed. The buyer pays a deposit (typically 10–30%). If the buyer withdraws, the deposit is forfeited. If the seller withdraws, they must repay double the deposit. CPCV is a binding legal document — always have a Portuguese lawyer review it before signing.

NOI divided by annual mortgage payments. Measures the cushion between rental income and debt obligations. A DSCR of 1.25x means the property generates 25% more income than needed to service the debt — the minimum most lenders and conservative investors want to see.

Formula: DSCR = NOI / Annual debt service

Below 1.0x: the rent does not cover the mortgage. Above 1.25x: healthy margin for vacancy, rate rises, or unexpected costs.

The percentage difference between a property's asking price per m² and the trailing average price per m² for comparable properties in the same zone. A negative delta (e.g. −12%) indicates the property is priced below the zone average — one of the primary signals investifique monitors to identify potential undervaluation.

The final deed of sale, signed in front of a Portuguese notary (notário) in the presence of both buyer and seller (or their legal representatives). IMT and IS must be paid before the escritura is signed. After signing, the transfer is registered with the land registry (Conservatória do Registo Predial). This is the moment legal ownership transfers.

The Euro Interbank Offered Rate — the base rate for most variable-rate Portuguese mortgages. Lenders price mortgages as EURIBOR (typically 3-month or 12-month) plus a spread of 1.5–2.5% for non-resident investment buyers. When EURIBOR rises, so does your mortgage payment — a key risk for investment properties with thin DSCR margins.

Annual gross rent divided by purchase price. The simplest yield metric — useful as a first-pass filter but not sufficient for investment decisions because it ignores vacancy, IMI, operating costs, and financing. Always model to cap rate before committing.

Formula: Gross yield = (Monthly rent × 12) / Purchase price × 100

Portuguese: Rentabilidade bruta

Portugal's annual property tax, levied at 0.3–0.45% of the VPT (tax assessed value) for urban properties. The VPT is typically lower than market value. As a working estimate, budget 0.4% of purchase price per year. IMI is a recurring cost that reduces NOI every year and must be included in any cap rate calculation.

IMI is paid directly by the owner — it is not charged to tenants. Bills arrive from Finanças (Portuguese tax authority) annually or in instalments.

Portuguese property transfer tax, paid once at acquisition. For investment properties and second homes (the category most foreign investors fall into), the rate is a flat 6.5% of purchase price. For primary residences, a progressive scale applies with rates between 0–7.5%.

IMT is one of the largest acquisition costs. On a €250,000 investment property: €16,250. Budget for it explicitly — many investors underestimate total acquisition costs by treating IMT as a footnote rather than a headline number.

The Portuguese income tax category that covers rental income. Non-resident investors pay a flat 28% on net rental income (gross rent minus allowable deductions: IMI, insurance, maintenance, condominium fees). Declared annually via the Portuguese tax authority (AT). EU/EEA residents may opt to aggregate with other income at progressive rates — potentially more favourable for lower income levels.

Stamp duty, paid at acquisition. Two components: 0.8% on the deed value (purchase price) and 0.6% on the mortgage amount. On a €250,000 property financed with a €175,000 mortgage: IS = €2,000 (deed) + €1,050 (mortgage) = €3,050.

The mortgage amount as a percentage of the property's appraised value. Portuguese banks lend up to 80% LTV for residents buying a primary residence; for non-residents buying investment properties, the typical maximum is 70% LTV. This means a minimum 30% down payment — before acquisition costs.

Higher LTV = more leverage = more sensitivity to rate changes and vacancy. A 70% LTV investment in Portugal at 5.5% interest rate leaves thin DSCR on most deals.

Portuguese tax identification number. Required for any property transaction, bank account opening, or contract in Portugal. EU citizens can obtain one at a Finanças office in person. Non-EU citizens need a Portuguese fiscal representative to apply on their behalf — this can be arranged remotely for ~€100–200/year. Getting a NIF is the first administrative step for any foreign investor.

Annual rental income minus vacancy loss minus all operating expenses (including IMI, condominium fees, maintenance, insurance). NOI is calculated before mortgage payments — it measures the property's performance independent of financing. NOI is the numerator in both cap rate and DSCR calculations.

Formula: NOI = Annual rent − Vacancy loss − Operating costs − IMI

Portuguese: Rendimento operacional líquido

The margin a Portuguese bank charges above EURIBOR on a variable-rate mortgage. Expressed in basis points or percentage points: a "1.8% spread" means the mortgage rate is EURIBOR + 1.8%. Spreads for non-resident investment mortgages typically range from 1.5–2.5% depending on the bank, loan-to-value, and applicant profile.

The percentage of time a property sits empty between tenants. In established Lisbon zones, vacancy for long-term rentals is typically 3–6%. In emerging zones or with high turnover, budget 8–10%. Vacancy reduces effective annual rent and must be modelled explicitly — not omitted from yield calculations.

Effect: 5% vacancy on €18,000 annual rent = €900 lost income per year.

The tax assessed value of a property, used by Portuguese tax authorities as the basis for IMI and other property-related taxes. The VPT is typically set below market value — often 50–70% of the actual transaction price — though this varies widely. IMI is calculated on VPT, not on purchase price; when estimating IMI for a property before purchase, use 0.4% of purchase price as a working approximation.

A general term for the return on a property investment expressed as a percentage of its cost or value. Yield means different things depending on what costs are included — always specify gross yield, net yield, or cap rate when quoting a number. In Portuguese property investment, "yield" without qualification usually refers to gross yield (annual rent / price).
