LTV, or loan-to-value, is the percentage of a property's value financed by debt. In 2026, Portugal's average gross rental yield is 4.29% according to Global Property Guide, so investors need to be careful: high leverage can erase the operating yield through mortgage payments.
What is LTV?
An LTV of 75% means the bank finances 75% of the property value and the investor contributes 25% plus acquisition costs. Higher LTV uses less upfront capital, but it also increases monthly debt service.
LTV formula
The same property at three LTVs
Assume a €250,000 property with €13,000 NOI. The property is identical in every row; only the financing changes.
| LTV | Loan | Annual debt service | DSCR | Pre-tax cash flow |
|---|---|---|---|---|
| 60% | €150,000 | €8,340 | 1.56x | €4,660 |
| 70% | €175,000 | €9,720 | 1.34x | €3,280 |
| 80% | €200,000 | €11,100 | 1.17x | €1,900 |
Higher LTV can improve cash-on-cash only while the property remains comfortably cash-flow positive. Once DSCR falls too far, the apparent capital efficiency becomes financial fragility.
What LTV is prudent for Portugal rental property?
In 2026, with the ECB deposit facility rate at 2.25%, financing is easier than at the 2024 peak but still material. For long-term rental property, 65% to 75% is often the prudent zone if DSCR stays above 1.25x.
Run it now: use the LTV stress-test calculator to compare loan size, DSCR, cash flow, and risk across financing scenarios.
