A Regra dos 30%

No Brasil, os bancos limitam o comprometimento de renda a 30% da renda bruta familiar para financiamento imobiliário. Com renda familiar de R$10.000: parcela máxima de R$3.000. Dívidas existentes (carro, cartão) reduzem o valor disponível. Um financiamento de carro de R$800/mês deixa R$2.200 para o imóvel.

Otimizando

Quite dívidas antes de solicitar financiamento. Quitar um carro de R$800/mês libera ~R$120.000 de capacidade de financiamento adicional (a 10%/ano em 30 anos).

⚡ CalcWolf Insight

The single most impactful DTI improvement: pay off credit card balances. Credit cards have the highest minimum payment relative to balance of any debt type. Paying off $5,000 in credit card debt eliminates roughly $150/month in minimum payments — a 2-3% DTI improvement on a typical income.
