Rapporto Rata-Reddito (30%–35% DTI)

Italian credit institutions evaluate mortgage eligibility based on the Rapporto Rata-Reddito (installment-to-income ratio). Monthly installments should not exceed 30% to 35% of certified net monthly household income, after subtracting any ongoing consumer loans.

Fondo di Garanzia Prima Casa (Consap)

Young home buyers under 36, single-parent families, and young couples can access the Consap State Guarantee Fund, which guarantees up to 80% of loan principal on primary residences up to €250,000, enabling banks to finance up to 100% LTV.

Tasso Fisso (Eurirs) vs Tasso Variabile (Euribor)

Fixed mortgages (tasso fisso) are tied to the Eurirs (Euro Interest Rate Swap) benchmark plus the bank's spread, providing payment security for up to 30 years. Floating rate mortgages (tasso variabile) are tied to 1M or 3M Euribor. Borrowers can renegotiate or subrogate (portabilità del mutuo) to another bank free of charge under the Bersani Law.

TAEG and Imposta Sostitutiva

The TAEG (Tasso Annuo Effettivo Globale) represents total cost including appraisal (perizia), loan origination (istruttoria), and mandatory fire insurance (scoppio e incendio). The substitute tax (imposta sostitutiva) is 0.25% for a primary residence (prima casa) and 2.0% for second homes.
