Risks of buying an off-plan property: how to protect your investment, from developer insolvency to purchase termination?
Risks of buying off-plan: developer insolvency, INCC adjustments and purchase terminations of up to 50%. See how the segregated estate (patrimônio de afetação) protects your investment.
The off-plan buying risks that destroy the most wealth are developer insolvency, the absence of a segregated estate (patrimônio de afetação, Law 10,931/2004), the mismatch between the INCC (Brazil's National Construction Cost Index) and your income, and a poorly calculated purchase termination — which lets the developer keep up to 25% (or 50%) of what you paid (Law 13,786/2018). Protecting the investment means choosing a project with a segregated estate, sizing the monetary adjustment and knowing your exits (assignment of rights) before you need them.
Buying off-plan is, at its core, a leveraged investment in a promise: you hand over capital today betting that a private company will finish a building in 3 years. When it goes well, the launch discount and the appreciation pay off. When it goes wrong — the developer goes under, the INCC spikes, life changes and you need out — the buyer discovers that a risk you never assessed is a risk you assumed. Famous insolvency cases in the industry have left tens of thousands of families with no home and no money.
While our articles on off-plan buying mistakes and construction delays cover the contract and the schedule, this one looks at the off-plan purchase as an investment: the structural financial risks and the legal mechanisms that shield (or expose) your capital.
What happens to my money if the developer goes under?
It all comes down to a single word on the property record (matrícula): afetação. Under the segregated estate regime (Law 10,931/2004), the project's land, construction and revenues are kept separate from the real estate developer's general assets — they cannot be reached by the company's debts. If the company goes bankrupt, the buyers can take over the project and finish it, preserving their investment. Without a segregated estate, your money goes into the company's single cash pool: if it fails, you become a creditor waiting in the bankruptcy line, often recovering cents on the real. Before signing, confirm that the segregated estate is annotated on the property record — it is the difference between project risk and company risk.
How can the INCC erode the viability of the purchase?
During construction, the outstanding balance is adjusted by the INCC construction cost index, which in high-inflation cycles has topped 14% a year — while your income does not keep pace. The financial risk is the mismatch: the final payment due at delivery keeps growing, the bank assesses the property and your income as they stand at that moment when you apply for financing, and the gap between the adjusted balance and the approved loan has to come out of your pocket. Protection: simulate the balance with a stressed INCC (pessimistic scenario), keep an income cushion of at least 30% and track the balance quarterly.
I need out of the deal: purchase termination or assignment of rights?
Life changes — and how you exit determines the size of the loss:
| Exit | How it works | Typical cost |
|---|---|---|
| Purchase termination (walking away) | Termination settled with the real estate developer | The developer keeps up to 25% of what you paid — or up to 50% with a segregated estate (art. 67-A of Law 4,591/64) |
| Assignment of rights | Selling your contractual position to a third party | Developer consent fee set in the contract; potential to recover up to market value |
It works well when the project has appreciated and there is demand — the assignment can even turn a profit. Risk: cold markets demand a discount; even so, it usually loses less than a purchase termination. The choice is mathematical, not emotional: run both numbers before telling the developer anything.
Which warning signs come before a project fails?
- Construction visibly behind the published physical schedule;
- Frequent changes of the contracted builder, or work stoppages;
- The developer falling behind with suppliers (protested debts, lawsuits at the TJSP — public search);
- Evasive communication in the construction progress reports;
- Aggressive “inventory clearance” promotions mid-construction (a sign of cash needs).
Spotting trouble early widens your options: an assignment before the crisis, formal notices preserving your rights, joining forces with other buyers and, at the limit, the buyers' committee provided for in Law 4,591/64.
A concrete example: Sandra's investment
Sandra compared two similar towers in 2024, both priced at R$ 480,000. Tower A, with no segregated estate, offered a 5% discount; Tower B, with a segregated estate annotated on the record and a developer with no protested debts, was full price. She chose B and kept a reserve for the INCC. In 2025, Tower A's developer filed for court-supervised reorganization with the building 40% complete — its buyers are still negotiating haircuts today. Tower B ran 3 months late (within the tolerance period) and was delivered; Sandra's unit was appraised at R$ 575,000 at handover. The 5% discount she turned down would, in the other scenario, have cost her the entire investment.
The most common (and costly) mistakes
- Choosing on discount, not on structure. Risk: saving 5% and risking 100%.
- Ignoring whether the segregated estate is annotated on the record. Risk: becoming an unsecured creditor of a bankrupt estate.
- Stretching your income to the limit, with no cushion for the INCC. Risk: losing the property in the final stretch because the financing falls through.
- Terminating on impulse. Risk: giving away up to half of what you paid when an assignment would recover far more.
Frequently asked questions
What is the segregated estate (patrimônio de afetação) and why does it protect buyers?
It is the regime created by Law 10,931/2004 that separates the project's land, construction and revenues from the real estate developer's general assets. Those assets cannot be reached by the company's debts: if it goes bankrupt, the buyers can take over and finish the construction. The segregated estate is annotated on the project's property record (matrícula) — confirm it before signing.
Is buying an off-plan property worth it as an investment?
It can be: there is a launch discount and appreciation potential until delivery. But the return depends on manageable risks — the developer's solidity, the segregated estate, the INCC index and your exit liquidity. Without that analysis, the off-plan “discount” merely pays you for a risk you did not realize you were taking.
If I back out of the purchase, how much can the developer keep?
In a purchase termination initiated by the buyer, up to 25% of the amounts paid — or up to 50% when the project has a segregated estate (art. 67-A of Law 4,591/64, added by Law 13,786/2018). Before terminating, run the numbers on an assignment of rights to a third party: in many cases it recovers market value and dramatically reduces the loss.
How do I know whether a developer is reliable?
Check: the segregated estate annotation on the property record, a track record of on-time deliveries, tax and labor certificates, protested debts, lawsuits over delays or defects at the TJSP (public search) and complaints filed with Procon-SP. A newly created single-project developer (SPE) with no segregated estate and no track record concentrates maximum risk in your contract.
When should I see a lawyer before investing in an off-plan property?
At the project analysis stage — before you make an offer. Verifying the segregated estate, the certificates and the contract is what turns the purchase into a calculated investment. And come back at the first sign of trouble with the construction, or before any purchase termination: the choice between exiting, assigning or holding on is legal and financial at the same time.
Investing off-plan is about managing risks — and almost all of them have a legal antidote
A segregated estate on the record, an INCC you have sized, construction warning signs you monitor and exits you have calculated: with these four safeguards, off-plan buying goes back to being what it promises — a discounted purchase with appreciation. Without them, it is a bet placed with a lifetime's capital. The difference between the two scenarios is decided before you sign.
