Example: $1M loan, 7.5% IO for 10 years. Years 1-10: $6,250/month (interest only). Years 11-30: $8,988/month (principal + interest on 20-year schedule).

Interest-only loan requirements: Credit: 680+ (jumbo IO), 620+ (Non-QM IO). Income: $250K+ annual (most jumbo lenders). Down payment: 20-30% (jumbo), 25-35% (Non-QM).

What happens after the interest-only period ends?▼
After IO period ends (typically 10 years), your loan converts to fully-amortizing and payments JUMP 30-50%. Example: $1M loan, 7.5% rate, 10-year IO. Years 1-10: $6,250/month (IO only). Years 11-30: $8,988/month (P&I on 20-year schedule) = +$2,738/month increase (+44%). Most IO borrowers (80%+) refinance or sell before IO period ends to avoid payment shock. Strategy: Use IO savings to invest, build business, or save for larger down payment on next home.
Are interest-only mortgages risky?▼
IO mortgages have 3 main risks: (1) Payment shock: Payments jump 30-50% when IO ends if you don't refinance; (2) No equity buildup: You don't pay down principal during IO period — only gain equity from appreciation; (3) Market risk: If home value drops, you could be underwater when IO ends. WHO SHOULD AVOID: Buyers on tight budgets, first-time buyers, anyone who can't afford the fully-amortizing payment. WHO CAN USE SAFELY: High-income professionals ($300K+), wealthy investors, borrowers with strong exit strategy (sell/refinance before IO ends), disciplined savers who invest the payment difference.
Can I refinance an interest-only loan before the IO period ends?▼
Yes, 80% of IO borrowers refinance before the IO period ends to avoid payment shock. Refinance strategy: (1) Start with 10-year IO at 7.5% = $6,250/month on $1M loan; (2) After 5-7 years, home appreciates $200K and your credit/income improve; (3) Refinance to new 30-year fixed at 6.5% or new 10-year IO; (4) Lock in lower rate or extend IO period. Best time to refinance: 2-3 years before IO period ends, when you have 20%+ equity and strong credit/income.
