Financing to build a house: complete guide for Criciúma and the region

Updated on 07/06/2026 by EZA Engenharia

Financing to build a house is one of the stages that weighs most on the decision of those who dream of their own project in Criciúma and the region. And it is different from buying a finished property: here the credit follows a logic all its own, with disbursement in stages, a stack of specific documents and technical monitoring from the first brick to the handover of the keys. After more than 35 years building high-end residences in the region, EZA Engenharia has seen this process from every angle, and knows that understanding how it works avoids delays, rework and budget surprises.

What is home construction financing and how it works

A home construction loan is a line of credit designed for those who will build a residence from scratch, whether on their own land or on land bought together with the project. The difference from a traditional loan for a finished property is simple to understand: the money doesn't land in the client's account all at once. The bank releases it gradually, tracking the real progress of the work, measured by periodic inspections.

This logic protects both sides, the bank and the owner. Each released installment corresponds to a stage that has already been delivered: foundation, structure, masonry, installations, finishing. That's why the physical-financial schedule needs to be well tied down from the start, with a construction company able to translate the project into clear stages for the lender to understand and release funds without hassle.

In Criciúma and the neighboring cities, Içara, Forquilhinha, Nova Veneza, this model is the normal path both for those who build on family land and for those starting from scratch on a new lot, including in areas like Balneário Rincão, where the standard of the houses tends to be higher.

Credit options available for those who want to build

There are several construction financing lines, each with its own rules for maximum amount, interest rate and term. The right choice depends on the client's income, the total cost of the project and the profile of the project itself.

Among the options that most often come up for those building a high-end house are:

• Real-estate financing under the SAC or Price amortization systems, with rates tied to the savings account (poupança) or to indexes such as the IPCA, offered by banks and credit cooperatives.
• Real-estate consortium, an interest-free option but with a waiting period for allocation that requires planning ahead.
• Own funds combined with partial financing, a common path in high-end projects to reduce the total financed amount.
• Specific lines for professionally assisted self-building, when the client takes a closer part in the management together with the construction company.

Technical documentation: what the bank requires before releasing the credit

The paperwork tends to be what raises the most questions. Unlike buying a finished property, financing to build a house requires a set of technical documents that prove the project is feasible and complies with the law.

Among the main items are the deed or updated land registry of the lot, the architectural design approved by the city hall, the ART or RRT of the responsible engineer, the detailed project budget and the physical-financial schedule. Many banks also request the structural calculation report and, in some cases, the descriptive specification of finishes.

Having a construction company with in-house engineering, as is the case with EZA, makes this stage much easier. The entire technical dossier comes from within, with the experience of those who have already led projects such as Residence V.S in Criciúma and Residence A.F in Balneário Rincão, without having to chase around between client, bank and freelance professionals.

Phased construction: how the schedule affects credit release

Building in stages is not just a bureaucratic requirement from the bank. It is also the safest way to run a high-end project. Each released phase is a physical milestone that can be verified, and this protects the client from paying for a service that has not even been done yet.

A well-planned schedule usually follows the sequence of site preparation and foundation, structure and masonry, roofing, electrical and plumbing installations, claddings and window and door frames, and finally finishing and landscaping. A delay in one stage holds up the release of the next installment, which is why professional construction management weighs directly on the client's cash flow.

Projects like the expansion we did in Althoff Laguna clearly show how a well-built stage schedule avoids stoppages and keeps the pace aligned with the bank's disbursement calendar.

Financial planning: beyond the approved financing

Getting credit approval is only part of the path. The amount released by the bank rarely covers one hundred percent of the final cost of a high-end residence, especially when design customization, premium finishes and items the client chooses over the course of the project come into play.

That is why the ideal approach is to keep a safety margin in your personal budget, accounting for possible material price adjustments, design changes during execution and complementary items such as landscaping, automation or climate control. The exact cost of a project varies widely depending on the site, the finish standard and the complexity of the design, which is why each estimate is handled on request, based on the descriptive specification defined together with the client.

EZA follows this planning from the very first conversation, helping the client see what weighs on the final cost before closing the financing, so that the amount approved by the bank matches the reality of the project.

The role of the construction company throughout the financing process

It is worth understanding the difference between a construction company and a real-estate developer in this context. The real-estate developer is the company that launches and sells developments, often with several units sold before or during construction. The construction company, on the other hand, is the one that actually carries out the project, from the architectural and structural design to the handover of the keys.

EZA Engenharia operates as a construction company, with an in-house engineering team, which means technical responsibility over every stage of the project, from assembling the documents required by the bank to the execution and the inspections that release each installment of the financing.

With more than 35 years of activity in Criciúma, Içara, Forquilhinha, Nova Veneza, Cocal do Sul and Balneário Rincão, EZA has already accompanied dozens of clients along this path, including large-scale projects such as the Hotel Centenário, which gives technical assurance both to the client and to the financial agent analyzing the project.

Each project has its own particularities, and that changes the financing strategy: the client's income, the site, the timeline they have in mind and the finish standard chosen. That is why the first step is not to go straight to the bank, it is to talk to whoever is going to build the house. EZA Engenharia has more than 35 years of experience in Criciúma and the region, guides each client on the necessary technical documentation and builds the project schedule already taking the banks' requirements into account.
