The standard comparison: rental income divided by property value—the so-called cap rate—versus CDI. Done this way, the property almost always loses.
The problem isn’t the property. It’s that in this comparison, the investor is measuring the total return of fixed income against only half the return of real estate.
The comparison most people make—and why it’s incomplete
The typical reasoning: a property worth R$ 480,000 renting for R$ 2,500/month = R$ 30,000/year = 6.25% gross. CDB pays ~13.75% a.a. (⚠️ VERIFY—current Selic rate). The property “loses.”
This calculation ignores two components that make up the real return of the property:
- Asset appreciation: the property worth R$ 480,000 that became R$ 530,000 in 12 months delivered another 10.4%—which doesn’t enter the yield calculation
- Leverage: whoever financed 70% of the purchase put in R$ 144,000 of their own money—and the appreciation applies to the full R$ 480,000
Neither of these components exists in fixed income. They are structurally different, not merely numerically.
What the CDB actually delivers
A solid bank’s CDB at 100% of CDI delivers:
- ~13.75% a.a. gross (⚠️ VERIFY—current Selic target)
- ~11% a.a. net after income tax on the regressive scale (15% for terms above 720 days)
- Daily liquidity possible, but at the cost of higher withholding (22.5% below 180 days)
- Full return in reais—without structural protection against inflation of real assets
CDB works well for working capital, emergency reserves, and diversification. For long-term wealth, the real net return (above inflation) is what matters—and that number is smaller than it looks when inflation erodes the purchasing power of the amount.
The complete math for real estate in Florianópolis
Analysis scenario: 42 m² studio in Trindade, R$ 480,000 (⚠️ VERIFY average FipeZAP value Florianópolis 2026).
Return via rental (yield):
| Item | Amount |
|---|---|
| Gross annual rent | R$ 30,000 |
| Management fee (12% of rent) | -R$ 3,600 |
| Annual property tax (IPTUIPTUVer tudo →) estimated | -R$ 1,800 |
| Maintenance average (0.5% a.a.) | -R$ 2,400 |
| Net annual yield | ~R$ 22,200 (4.6%) |
Return via appreciation:
Florianópolis recorded average appreciation of 8% to 12% a.a. in the compact apartment segment between 2020 and 2025, according to FipeZAP (⚠️ VERIFY exact data in latest FipeZAP report). Using 8% conservatively:
- Annual appreciation on R$ 480,000 = R$ 38,400
- Total return (yield + appreciation) = R$ 60,600 = 12.6% a.a.
Against CDB net of ~11%, the property delivers more—with real asset protection and leverage potential.

Why Florianópolis has its own appreciation dynamics
Florianópolis doesn’t behave like the average Brazilian real estate market. Three structural factors explain the resilience and consistent appreciation:
Geographic supply constraint: an island with fixed perimeter and established neighborhoods. Horizontal growth hits physical barriers that don’t exist in continental cities. New supply is expensive and limited.
Structural and growing demand: Federal University of Santa Catarina (UFSC) with over 40,000 students and professors, University Hospital, expanding technology hub—constant generators of rental demand in specific neighborhoods.
Second-home and tourism market: Jurerê, Lagoa da Conceição, and Balneário Camboriú (broader region) sustain prices even in high-interest periods. Second-home buyers are less sensitive to Selic than primary-home buyers.
This combination of constrained supply with diversified demand creates an appreciation floor that less-specific markets don’t have.
The leverage factor—what CDB cannot replicate
Financing 70% of the purchase is an option that fixed income doesn’t offer.
Example with the same R$ 480,000 property:
- Down payment: R$ 144,000 (30%)
- Financing: R$ 336,000 (70%)
- 8% appreciation on R$ 480,000 = R$ 38,400
The R$ 38,400 appreciation gain applies to the entire asset—but the equity invested was R$ 144,000. The return on equity from appreciation is 26.7% before subtracting the cost of financing.
This mechanism only works when the rental income covers or approximates the loan installment. If rental income is insufficient to cover the debt service, the equation changes. The viability analysis should include this calculation before the purchase decision.
For owners who already have the property and want to maximize rental return, the guide on how to rent out a property in Florianópolis details the process and decisions that impact net return.
For whom this investment makes sense
Real estate in Florianópolis delivers the complete return for investors with a specific profile:
- 5-year horizon or longer: appreciation needs time to materialize; short-term operations are diluted by transaction costs
- Capital for down payment and reserve: financing requires minimum 20-30% down and reserve for any vacancy periods
- Interest in wealth diversification: property in Florianópolis is protection against real-asset inflation and uncorrelated from variable income
- Passive management as the goal: with professional management, the investor doesn’t need to be in the city to manage—receives the rent, reports, and operational decisions are made by the agency
With Regente’s Total Guarantee, the rent hits the account on the scheduled date, regardless of what happened with the tenant. The return projected in the analysis is the actual return—no surprises from defaults or prolonged vacancy that distort the math.

Frequently asked questions about real estate ROI in Florianópolis
Is real estate in Florianópolis a good investment in 2026?
For those with a 5-year or longer horizon and calculating complete return (yield + appreciation), yes—especially in neighborhoods with structural demand like Trindade, Itacorubi, and Córrego Grande. The combined historical return beats net fixed income in most scenarios.
How much does a rental property earn in Florianópolis?
Average gross yield ranges from 5% to 7% a.a. depending on neighborhood and property type. Net, after management, property tax, and maintenance, it’s between 4% and 5.5%. Asset appreciation adds 6% to 12% a.a. historical—total return typically runs between 10% and 17% a.a.
Is it worth more to invest in property or fixed income?
It depends on horizon and profile. Fixed income delivers liquidity and predictability without management. Property delivers potentially higher total return, real-asset inflation protection, and leverage—but requires capital tied up longer. For long-term wealth, the combination is more robust than choosing one or the other.
Which Florianópolis neighborhood has the best rental yield?
Neighborhoods near UFSC (Trindade, Córrego Grande, Itacorubi) have long-term structural demand and low vacancy rates. Coastal neighborhoods (Lagoa, Jurerê) have higher ticket and seasonal demand. The best neighborhood for pure yield often differs from the best for appreciation.
How do you calculate the real return of a property?
Real return = (net annual rent + estimated appreciation) / equity invested. Equity is the down payment (not the total property value). Include in the calculation: management fee, property tax, HOA if any, average maintenance, insurance, income tax on rent (if applicable).
