Brazil's housing market expands with new mortgage financing rules and rising Gen Z home‑buying interest

Banks in Brazil are updating mortgage‑financing procedures for 2026, requiring proof of income that does not exceed about 30% of a household’s monthly earnings. Accepted documents include pay slips, tax returns, bank statements, and, for self‑employed borrowers, the Decore declaration, invoices or service contracts. Digital platforms and artificial‑intelligence tools are now used to cross‑check data, speeding approvals and reducing reliance on physical paperwork.

A recent market study shows that 56% of Brazilian Gen Z (ages 21‑28) plan to buy a home, the highest share among all age groups. The generation values quality of life, flexibility and urban experience over sheer size, prompting developers to focus on green spaces, multifunctional areas and well‑located projects.

Meanwhile, Santander’s online auction lists 205 properties across 21 Brazilian states, with lot prices ranging from R$ 25.9 thousand in Pernambuco to R$ 2 million in São Paulo. Buyers can pay in cash or finance up to 420 installments, but must watch for hidden debts and occupancy issues.
