A property's return should be calculated based on the total cost of entry and after accounting for vacancy, taxes, building expenses, management, and maintenance. The calculation for apartment 403 at Dēco Maggiolo below serves as a specific example of this model rather than a promise of results for another property.
Example calculation · Dēco Maggiolo · Apartment 403
NON-VPReady for immediate rental: 4th floor, 1 bedroom, 58.43 m² of living space, and a 20.22 m² terrace.
IRPF 10.5% on rental income – standard tax regime

The same net income is compared using two calculation bases: payment to the developer with Gastos and the total entry cost with all specified costs.

Methodology
The calculation was prepared by Uruguay Smart Estate based on market data from July 2026. VP status does not apply; IRPF of 10.5% applies to rental income. The developer discount is 10%. Scenario A's ROI is based on the post-discount price plus Gastos. Scenario B includes ITP, notary fees, Montepío, and the Uruguay Smart Estate commission of 3% plus IVA of 22%.
Detailed ROI calculation
At a rental rate of $1,650 per month, gross income is $19,800 per year. After IRPF, the management fee, and Contribución Inmobiliaria are deducted, net income is $15,323 per year.

Basis of calculation
To compare properties, use one entry basis, one period, and the same mix of income and expenses. Otherwise, a more attractive percentage may result from an incomplete denominator.
Full financial picture
The model should show not only income from the tenant, but also periods without income, regular payments, maintenance and costs that occur less than once a month.
Allow for a realistic vacancy period between leases and time to prepare the property for the next tenant.
Separate gastos comunes into the tenant’s payments and amounts that remain the owner’s responsibility under the contract or because of the nature of the work.
Confirm applicable taxes and municipal payments with a contador for the specific owner and ownership structure.
Consider management, tenant search, move-in, ongoing communication, and monitoring of the property’s condition.
Include insurance, minor repairs, appliance replacements, and a reserve for more substantial work on the building or apartment.
For a furnished property, include the initial furnishing and periodic replacement of furniture and equipment.
Separately, check bank expenses, currency conversion, and remittance costs if they are relevant to your scenario.
Stability testing
The numerical example Dēco 403 compares two entry bases. An investment decision requires a sensitivity model with the same formula and different assumptions about income and expenses.
Uses the confirmed rate, a typical lease-up period, and expected operating costs as of the calculation date. This is a working hypothesis, not a guaranteed forecast.
Checks for a longer vacancy, a rent concession, additional move-in or repair costs, and a more cautious estimate of net income.
Combines a decline in effective income with rising costs and unforeseen repairs to assess the liquidity buffer and allowable entry price.
Specify the source and date for price, rent, vacancy, expenses, taxes and management.
In all scenarios, use one period, one entry base, and the same income and expense categories.
First assess the impact of each parameter, then combine adverse changes in the stress scenario.
Check whether the property can support your intended holding period, cash-flow needs, and a contingency reserve.
Model risks
Two properties with similar calculated ROI may behave differently when tenants change, repairs are needed, the property is sold, or it is managed remotely.
The rental rate and time needed to find a tenant depend on the area, apartment type, condition, season, and competing supply.
Major work, changes in common expenses, or an inadequate building reserve fund can reduce actual cash flow.
An absent owner requires clear authority, reporting, oversight of contractors, and a reserve for urgent decisions.
The timing and price of a future sale are not known in advance; the base model should not substitute them with an assumed constant increase in value.
The owner’s income, expenses, and personal obligations may be denominated in different currencies, creating a separate risk.
Tax status, contractual structure and applicable payments require up-to-date verification for the specific owner.
