Buying an Off-Plan Property and Selling at Delivery: How Real Estate Arbitrage Strategy Works

Buying an off-plan property and selling at delivery is a strategy grounded in real estate market fundamentals: investors who enter at the pre-launch phase pay less than buyers purchasing at key handover, and that difference can represent a significant margin when all costs are factored in.

The problem lies in the “when.” Many investors who’ve heard stories of 30% appreciation over 3 years calculate using gross appreciation and forget to subtract the National Construction Cost Index (INCC), ITBIITBI — Imposto sobre Transmissão de Bens ImóveisImposto municipal sobre transferência onerosa de imóvel entre vivos. Em Florianópolis: alíquota de 2% sobre o valor declarado (STJ Tema 1.113).Ver tudo → transfer tax, Income Tax on capital gains, and resale brokerage fees. Real net margin typically falls well below the initial projection.

In Florianópolis, appreciation during construction can be substantial — historically between 15% and 35% depending on location and timeframe. But the strategy requires rigorous analysis before any commitment.

How does buying an off-plan property to resell at delivery work?

Buying an off-plan property and reselling means acquiring a property at the pre-launch or launch phase, paying installments during construction, and selling the contract or property — at a profit — before or shortly after key handover.

The arbitrage logic rests on three pillars:

• Entry discount: launches typically offer 10% to 20% discount off the list price for buyers entering at the pre-launch phase, before public sales campaigns begin.
• Appreciation during construction: a property under construction tends to be worth more at delivery than at launch, due to the risk the initial buyer assumes and market speculation during the construction period.
• Installment payments direct to builder: during construction, the buyer pays monthly installments directly to the developer — no bank interest, but with INCC adjustment.

The INCC is the variable many optimistic calculations ignore. This index adjusts installments during construction by the actual cost of civil construction, measured by Brazil’s IBGE statistical agency. In years with construction inflation above 10%, the outstanding balance grows significantly — reducing net margin even when the property’s market price rises.

The structure that maximizes return is: buy at pre-launch → pay installments during construction → sell the contract via contract assignment (cessão de posição contratual) before deed → or take possession, finance with a bank, and pocket the difference. For investors who prefer to keep the property and use rental income to service financing, leveraged hold is the alternative model.

What drives appreciation during construction in Florianópolis

Appreciation during construction is not uniform. It depends on variables the investor must evaluate before signing — not after.

The factors most influencing appreciation in Florianópolis:

• Location: neighborhoods with growing demand and limited land supply (Jurere Internacional, Centro, Coqueiros, Itacorubi) historically appreciate more during construction than regions with abundant supply.
• Builder quality: developers with proven on-time delivery and above-average construction standards attract buyers willing to pay more at delivery.
• Construction timeline: 36- to 48-month projects have more time to capture appreciation — and more time for INCC to erode margin. The ideal timeline for arbitrage strategy is 24 to 36 months.
• Market cycle: buying off-plan during a real estate cycle peak and delivering during stagnation can turn a 25% appreciation expectation into just 8% — insufficient to cover costs.

The real estate cycle matters as much as location. Entering at pre-launch at the start of an appreciation cycle and exiting at delivery with the market still hot is the ideal scenario. Missing timing is the strategy’s primary risk.

According to FipeZAP index data, Florianópolis ranked consistently in Brazil’s top 3 for appreciation between 2019 and 2025 — supporting the thesis, but not guaranteeing that any launch in any location will repeat that performance.

The costs that erode margin: ITBI, Income Tax, INCC, and brokerage

Real net margin from buying off-plan and reselling must deduct four costs that accumulate against gross appreciation:

INCC on installments during construction: average INCC in recent years has ranged from 6% to 12% annually, as measured by IBGE. On a 36-month project with 8% average INCC, corrected installments rise meaningfully — increasing total disbursement above the amount agreed at signing.

ITBI on transfer: 2–3% of the assessed value. Applies if the investor registers the property in their name before selling. On contract assignment — selling the contract before deed — ITBI incidence varies by municipality and deal structure.

Income Tax on capital gain: Brazil’s tax authority taxes real estate profit at 15% for gains up to R$ 5 million. On a transaction with R$ 80,000 gross appreciation, Income Tax consumes R$ 12,000 — eliminating much of the margin on a R$ 200,000 investment.

Resale brokerage: 6% of sale price. On a R$ 480,000 resale, that’s R$ 28,800 paid directly from margin.

The real net margin is what remains after all these deductions:

Gross appreciation − Accumulated INCC − ITBI − Income Tax − Brokerage = Net margin

For a transaction with 25% gross appreciation and typical costs, real net margin lands between 10% and 15% on purchase price — over a 3-year period. It’s not a bad return, but it’s far from the “30% in 3 years” story without discounts.

In practice, what surprises investors most is the cumulative effect of these costs. Each one in isolation seems small. Together, they consume 10 to 15 percentage points of gross appreciation.

Contract assignment: how to sell before the deed

The contract assignment (cessão de posição contratual) is the legal mechanism allowing the buyer to transfer the developer contract to a third party — before key delivery and before any deed filing at the notary office.

It works as follows: the original buyer (assignor) transfers all rights and obligations of the purchase contract to the new buyer (assignee), through payment of an amount reflecting the asset’s appreciation. The developer must authorize the assignment — most accept, some charge an administrative fee of R$ 2,000 to R$ 5,000.

Assignment avoids notary registration and can defer or simplify ITBI incidence. But it creates its own tax event: the assignor calculates capital gain on the difference between amounts paid and amounts received from the assignment, and must remit corresponding Income Tax.

The opposite risk to assignment is rescission (distrato): withdrawing from the contract before delivery. The law allows rescission, but the penalty can reach 25% of all amounts paid — wiping out profit entirely and leaving the investor with real losses. Anyone signing an off-plan contract must have financial capacity to carry it through or find an assignee before needing to withdraw.

Verification of segregated funds (patrimônio de afetação), established by Law 10.931/2004, protects the buyer in the opposite scenario: if the builder defaults, project assets remain segregated from the company’s general assets — reducing the risk of losing the property due to developer financial problems. Verifying segregated funds status is a primary step before signing. See the guide on buying off-plan property in Florianópolis to understand this point in greater detail.

Comparing this strategy to house flipping, remember that off-plan requires less upfront capital (monthly installments versus cash purchase) and less renovation risk exposure — in exchange for longer duration and developer risk.

Frequently Asked Questions — buying off-plan and reselling: the real math

What is the real appreciation margin off-plan in Florianópolis?

Gross appreciation during construction ranges from 15% to 35% depending on location, timeline, and market cycle. Real net margin, after INCC, ITBI, Income Tax, and brokerage, typically lands between 10% and 20% on purchase price — over a 24- to 48-month period.

What is contract assignment and how does it work in practice?

It’s the transfer of the original purchase contract to a new buyer, before deed registration. The assignor receives accumulated appreciation; the assignee assumes the outstanding balance with the developer. The transaction requires developer authorization and triggers an Income Tax event for the assignor on the calculated gain.

Does rescission eliminate profit?

Yes, in nearly all scenarios. Rescission penalty can reach 25% of all amounts paid. An investor who paid R$ 40,000 in installments and decides to withdraw might receive back only R$ 30,000 — and still lose the time invested and cost of capital.

Can INCC erode all appreciation?

In periods of very high INCC (above 10% p.a.) and property appreciation below average, yes — INCC can consume significant portions of gross margin. Risk increases on long projects (more than 48 months) and in construction inflation cycles higher than expected.

How do you select the right launch for this strategy?

Four main criteria: location with growing demand and constrained land supply, developer with proven on-time delivery track record, construction timeline of 24 to 36 months, and pre-launch entry — when the discount off list price is still available.
