Two acronyms decide whether Brazilian mortgage financing costs 9% or 13% a year — a difference that, on a high-end property, means tens of thousands of reais a year in interest alone. And in 2026 a change happened that shifts the game specifically for buyers in Balneário Camboriú, Itapema and Porto Belo.
Why this is the question that decides the cost of financing
Compare the two scenes below — the same financing request, two different agents:
- Agent who doesn't know: client asks "why did my financing come out with such higher interest than my friend's?" Answer: "each bank has a different rate." The client never finds out their property simply didn't qualify for the cheaper system.
- Agent who knows: same question. Answer: "your friend's property fell under SFH, with a R$2.25 million cap and interest up to 12% a year — yours, if it's above that, falls under SFI, with free-market interest, usually above 13%. Let's see if we can restructure it to fit under the cap." The client understands exactly where the money is going.
SFH: the system with a cap and lower interest
Brazil's Housing Finance System (SFH) is the "traditional," regulated financing, funded by FGTS (Brazil's severance fund) and savings deposits:
- Property value cap: R$2,250,000 (raised from R$1,500,000 in 2026).
- Interest: up to 12% a year by law, but banks typically offer between 8% and 10% a year in practice.
- FGTS: can be used as a down payment or to pay down installments.
- Term: up to 420 months (35 years).
- Minimum down payment: usually 20% (financing up to 80% of the value).
SFI: the system with no cap, for anything above the limit
Brazil's Real Estate Financing System (SFI) was created in 1997 specifically to cover what SFH couldn't reach: high-end, commercial, and land properties.
- Property value cap: none.
- Interest: free market rates — usually above 13% a year.
- FGTS: cannot be used.
- Funding source: the bank uses its own capital or funds raised from investors, not FGTS/savings deposits — which is why it costs more.
- Terms: negotiated directly with the bank, case by case.
The 2026 shift: the cap that changed the game in BC and Itapema
In 2026, the SFH cap rose from R$1,500,000 to R$2,250,000. That matters enormously for this region: 2-3 bedroom apartments in Balneário Camboriú and Itapema that used to exceed the old cap and automatically fall under SFI (pricier interest) can now qualify for SFH — if the price stays within the new limit.
| SFH | SFI | |
|---|---|---|
| Value cap | R$ 2,250,000 | No cap |
| Interest (per year) | 8% to 12% | Above 13% |
| FGTS | Can be used | Cannot |
| Maximum term | 420 months | Negotiated |
| Typical buyer | Residential up to the cap | High-end, commercial, land |
Example — the interest difference in the first year
A R$1,500,000 financing — within the new SFH cap — compared under both systems:
| System | Rate (illustrative) | Interest in year 1 alone |
|---|---|---|
| SFH | 9%/year | R$ 135,000 |
| SFI | 13%/year | R$ 195,000 |
| Difference | R$ 60,000 in the first year alone |
This is an illustrative simulation — the actual rate varies by bank, banking relationship, and buyer credit profile. But the size of the gap shows why it's worth checking which system a property qualifies for before closing the deal.
In practice: what to ask before financing
- Is the property's value within the R$2.25 million cap? If it's right at the edge, it's worth checking whether the price can be structured to stay under SFH.
- Can I use FGTS? Only possible under SFH — not under SFI.
- Which bank offers the best rate within SFH? Even inside the same system, that 8-12% range varies bank to bank.
The difference this makes in a broker's career
Knowing how to explain SFH and SFI — and remembering the updated 2026 cap — is the kind of information that can literally change the final price a client pays for a property over the years. An agent who helps a client fit into the right system saves them tens of thousands of reais — and earns a long-term referral.
