The primary reason borrowers must seek alternative financing to obtain Interest-Only payment mortgage is due to federal regulation established by the Consumer Financial Protection Bureau (CFPB).
Qualified Mortgage (QM) Restrictions: QM loans, which became the standard in 2014, were introduced to provide safer and more sustainable home loans for consumers. The Dodd-Frank Act requires lenders to determine a borrower’s ability to repay (ATR). Crucially, the act explicitly mandates that qualified mortgages cannot have risky loan features such as negative amortization, interest-only, balloon payments, terms beyond 30 years, or excessive points and fees.
Non-QM Allowance: A Non-Qualified Mortgage (Non-QM) is any home loan that does not comply with the QM rules. Since the IO payment feature is prohibited under QM rules, it is inherently classified as a Non-QM loan feature. Non-QM financing allows lenders to offer the IO option while still adhering to the Ability-to-Repay (ATR) rule requirements.
IO payment features are available across multiple Non-QM product lines, catering to different borrower profiles (e.g., standard income, alt doc, or investors).
| Non-QM Program | Example IO Product Terms | Applicable Loan Term | IO Period | Amortization Period |
| Standard/Full Doc | 30 Yr Fixed IO | 360 months | 120 months (10 years) | 240 months (20 years) |
| Alternative Doc (e.g., Bank Statement) | 40 Yr Fixed IO | 480 months | 120 months (10 years) | 360 months (30 years) |
| DSCR (Investor Cash Flow) | 40 Yr Fixed IO | 480 months | 120 months (10 years) | 360 months (30 years) |
| Non-QM ARMs | 7/6 SOFR ARM IO | 360 or 480 months | 10 years | Remaining term |
| Elite Jumbo | 40 Yr Fixed IO | 480 months | 10 years | 30 years |
Non-QM products commonly feature a 10-year interest-only period. After this period, the loan converts to a fully amortized payment for the remaining term. Loan terms offering IO payments often extend beyond 30 years, such as the 40-year fixed IO loan.
Borrowers, particularly investors and retirees, seek IO features for strategic financial management:
While IO features provide flexibility, they are subject to strict underwriting standards within Non-QM programs:
Interest-Only loans generally impose minimum credit scores and maximum Loan-to-Value (LTV) limits:
Although the borrower only pays interest during the IO period, the loan qualification is usually based on the higher, fully amortizing payment to ensure the borrower can afford the higher payment once the IO period ends.
The Interest-Only payment (ITIA) may be used to calculate the DSCR for Investor Cash Flow (ICF) transactions only if the LTV does not exceed 75%.
No, Interest-Only is not eligible for First-Time Homebuyers across several Non-QM programs.
The maximum LTV/CLTV allowed for Interest-Only features on purchase transactions is often capped at 85% in certain Non-QM series.
A minimum 700 FICO score is often required to qualify for Interest-Only payment features under many Non-QM programs.
The loan cannot be qualified at the interest-only payment. The borrower must qualify based on a simulated fully amortizing principal and interest payment over the remaining amortization term.
Non-QM programs frequently offer a 40-year fixed term loan that includes an Interest-Only payment feature.
The standard Interest-Only payment period is 10 years (120 months). After this period, the loan typically converts to a fully amortized payment.
Interest-Only Non-QM loans can help retirees manage cash flow.
A borrower must use a Non-Qualified Mortgage (Non-QM), which does not comply with QM rules. Interest-only loans are an example of a Non-QM loan.
Traditional loans, or Qualified Mortgages (QM), cannot have risky loan features such as interest-only, balloon payments, or negative amortization, as mandated by the Dodd-Frank Act.
