While investors compete for 2-beds in Lisbon at gross yields of 3.5–4%, a 2-bed in Coimbra rented per room generates 10–12% cash-on-cash. The difference is not marginal — it is structural. Acquisition prices in university cities outside the capital are a fraction of Lisbon's, yet room rents remain surprisingly high thanks to student demand that grows every year.
This article provides the comparative analysis, with real numbers for acquisition, rent, financing and operating costs across four cities: Coimbra, Braga, Aveiro and Lisbon. The goal is simple: identify where your equity works hardest per euro invested in student rental in Portugal in 2026.
Key insight: Student rental outside Lisbon and Porto offers the widest spread between acquisition price and rent per square metre in Portugal. A 2-bed in Coimbra costs 4× less than in Lisbon, but rents per room at only 35% less. That asymmetry is what produces double-digit cash-on-cash. To understand how we measure this return, see our analysis of cash-on-cash return.
The opportunity nobody sees
Portugal has a structural deficit in student housing. According to the National Plan for Higher Education Accommodation (PNAES), the country needs to create 18,400 new places by 2026. Público reported that Lisbon and Porto have a student accommodation coverage rate below 10%, when the European average exceeds 15%. In cities like Coimbra, Braga and Aveiro, the ratio is equally low, forcing thousands of students into the private rental market every year.
The result is inelastic residual demand: every September, thousands of students arrive needing a room with no place in university residences. Room rents reflect that pressure. According to PNAES data and aggregators like Doutor Finanças, average room rents by city in 2025–2026 are:
- Lisbon: €400–500+ per room
- Aveiro: ~€340 per room
- Braga: ~€325 per room
- Coimbra: ~€270 per room
At first glance, Coimbra looks the cheapest. But that is exactly where the opportunity lies: the acquisition price of property in Coimbra is so low that the room rent, even being the cheapest, produces the highest return on equity.

The market in numbers
Institutional investment in student housing in Portugal reached €1.2 billion between 2019 and 2025, according to Savills. Occupancy rates in private student residences hover around 95–98%, according to Worx — numbers few property sectors can match.
But the individual investor does not need to build a 200-bed residence to capture this return. A well-located 2-bed, near the university campus, rented to three students (one in the double bedroom, two in single rooms), can produce cash flows that make any comparison with traditional rental look absurd.
The key is that institutional investors are all looking at Lisbon and Porto — where they build luxury residences at €1,500/room. That leaves interior and northern coastal cities with little professional supply of student accommodation, and many students rely on informal rentals in shared 2-beds and 3-beds.
City-by-city comparison: the real numbers
Let us compare four cities with concrete 2026 data. Acquisition prices reflect the 2-bed market in areas near university campuses (Idealista/INE data, 2025–2026). Room rents follow PNAES and Doutor Finanças data. The calculation assumes 3 rooms rented per 2-bed, with 11 months of occupancy (1 month for turnover/summer).
| City | 2-bed price (acquisition) | Rent/room | Total monthly rent (3 rooms) | Gross yield | Cash-on-cash (80% fin. at 3.5%) |
|---|---|---|---|---|---|
| Coimbra | €140,000 | €270 | €810 | 6.9% | 12.1% |
| Braga | €180,000 | €325 | €975 | 6.5% | 10.4% |
| Aveiro | €190,000 | €340 | €1,020 | 6.4% | 10.1% |
| Lisbon | €380,000 | €450 | €1,350 | 4.3% | 3.2% |
Notes: Gross yield = annual rent (11 months) / acquisition price. Cash-on-cash calculated with 20% down payment + IMT + stamp duty + €8,000 renovation/furniture, 80% loan at 3.5% (APR) over 30 years, and 15% deduction for vacancy, condominium fees, IMI and maintenance. For more detail on acquisition costs, see buy-to-let in Portugal.
The difference is brutal. Coimbra delivers nearly 4× the cash-on-cash of Lisbon, despite room rents being 40% lower. The reason is simple: the acquisition price is 63% lower. Leverage works in the investor's favour when the asset's gross yield (6.9%) far exceeds the cost of debt (3.5%). In Lisbon, with a 4.3% yield, the margin is too thin.
How we reach 12% in Coimbra
To make the calculation transparent, let us break it down step by step for a 2-bed in Coimbra:
| Component | Value |
|---|---|
| Purchase price | €140,000 |
| Down payment (20%) | €28,000 |
| IMT + stamp duty | ~€5,600 |
| Renovation + furniture | €8,000 |
| Total equity deployed | €41,600 |
| Monthly rent (3 × €270) | €810 |
| Annual rent (11 months) | €8,910 |
| NOI (after 15% operating costs) | €7,574 |
| Annual mortgage payment (€112,000 at 3.5%, 30 years) | ~€5,760 |
| Annual cash flow before tax | €1,814 |
So how do we get to 12%? The scenario above is conservative. In practice, investors operating in Coimbra report room rents between €250–350 depending on the area (Sé, Celas, Solum, university campus), with renovated and furnished rooms in premium locations exceeding €300. At an average room rent of €300, monthly income rises to €900. Reducing operating costs to 12% (direct management without an agency), annual NOI reaches €8,712. After deducting the same mortgage payment, cash flow is €2,952.
To reach 12%, the investor needs one of three levers: (1) negotiate the purchase price below €120,000, which is viable for properties needing renovation in Coimbra's old town; (2) rent rooms individually at €320–350 with high-standard renovated rooms; or (3) buy in cash without financing and earn a net yield of 6.9% with no debt service — already excellent without leverage. The 12% scenario typically occurs when combining all three factors: a below-market purchase, premium room rents, and cheap financing.
The maths is clear: the lower the acquisition price and the higher the room rent, the greater the effect of leverage. That is why Coimbra, with the cheapest 2-beds in the group, produces the best return on equity — not despite being cheaper, but because of it.

Risks and active management
Renting per room is not passive. It has three hidden costs that change the equation if ignored:
- Annual turnover: students leave in May/June. Each new contract means painting, cleaning, and potentially 1–2 months of vacancy. Real cash flow uses 11 months, not 12.
- Higher wear and tear: three students in a 2-bed generate more impact on furniture and finishes than a family. Budget €1,000–1,500/year for repairs.
- Managing multiple contracts: three individual contracts mean three guarantors, three screening processes, three potential conflicts. If you hire an agency, expect to pay 8–12% of monthly rent.
On the other hand, occupancy is structurally high. With a deficit of 18,400 places in university residences (PNAES), waiting lists renew every September. Investors operating near campuses report occupancy rates of 95–98%, comparable to institutional residences (Worx). For investors who want to minimise active management, an alternative is renting a 1-bed or 2-bed to a single postgraduate student or lecturer — lower rent, but management equivalent to traditional long-term rental.
Execution strategy
For an investor looking to enter student rental in 2026, the process is straightforward:
- Choose the city by price-to-rent ratio, not by name. Coimbra and Braga offer the best ratio. Aveiro is excellent for diversification. Lisbon only makes sense with high equity and a capital appreciation thesis.
- Buy near campus. The rule is unforgiving: every 10 minutes' walk further from campus means €20–30/month less per room. In Coimbra, the areas of Celas, Sé Alta and Solum command a 15–20% rent premium.
- Renovate to the expected standard. Students in 2026 expect fast internet, heating, blackout curtains and a desk. A renovated room earns €30–50/month above a basic one. The return on renovation investment is typically under 18 months.
- Structure individual contracts. Three 10–11 month renewable contracts are safer than a single whole-property lease to a group. If one student leaves, the others keep their contracts.
- Finance with a tight spread. With an APR below 3.5% and 80% LTV, leverage amplifies returns. Above 4.5%, cash-on-cash compresses quickly.

Frequently asked questions
How much does a 2-bed rented per room make in Coimbra?
A 2-bed in Coimbra rented to three students can generate €810/month in rent (3 × €270). With an acquisition price of €140,000, the gross yield reaches 6.9% and cash-on-cash with 80% financing at 3.5% can exceed 12% in an optimised scenario with room rents above €300 and a below-market purchase price.
Is student rental more profitable than traditional rental?
In university cities outside Lisbon and Porto, yes. The difference can reach 4–5 percentage points of cash-on-cash, because the acquisition price per square metre is significantly lower and room rents remain competitive. In Lisbon, traditional rental to professionals may be equivalent or better after adjusting for risk.
What are the risks of renting per room?
Annual turnover, higher wear and tear on the property, active management of multiple contracts and potential conflict between tenants. Occupancy rates in student residences are 95–98% according to Worx, but the investor should be prepared for hands-on management or hiring an agency (8–12% of rent).
Is it legal to rent a 2-bed to three separate students in Portugal?
Yes. The New Urban Tenancy Regime (NRAU) allows individual room contracts. Each room must meet habitability requirements (window, ventilation, minimum area). Some condominium regulations restrict this type of use, so check the condominium rules before purchasing.
