🧮 IO Payment Math — $800K Loan at 7.25%
| Scenario | Monthly | 10-Year Interest Paid | Balance After 10 Yrs |
|---|---|---|---|
| 30-yr amortizing @ 7.10% | $5,377 | ~$556,000 | ~$689,000 |
| 10-yr IO @ 7.25% | $4,833 | ~$580,000 | $800,000 (unchanged) |
| IO + self-pay $544/mo principal | $5,377 | ~$580,000 | ~$735,000 — equity built anyway |
The trade: IO costs ~$24K more interest over 10 years and builds no equity on its own — but frees $544/month. If you invest that at 8% (S&P average), you end ~$35K ahead. If you spend it, you're worse off. IO rewards discipline, punishes autopilot.

❓ Interest-Only Mortgage FAQs
How do interest-only mortgages work in 2026?
You pay only interest for 5-10 years (the IO period), then the loan converts to fully amortizing for the remaining 20-25 years — payments jump because you're paying off the full balance in less time. Example: $800K at 7.25% = $4,833/mo IO, then jumps to ~$6,320/mo when amortization starts. Most IO loans are structured as 7/6 or 10/6 ARMs.Get IO rate quotes →
What are interest-only mortgage rates in October 2026?
IO jumbo rates run 7.10-7.75% in October 2026, roughly 0.15-0.40% above standard jumbo pricing. Non-QM IO (bank statement, DSCR): 7.45-8.75%. The premium buys the lower payment during the IO window — on $1M, IO saves ~$800/month vs amortizing.See non-QM IO options →
Who should use an interest-only mortgage?
Legitimate uses: (1) High earners with variable income (bonuses, commissions) who will make lump-sum principal payments; (2) Investors maximizing cash flow on rentals; (3) Buyers certain they'll sell/refi within the IO period; (4) Wealth management strategy — invest the payment difference. NOT for: stretching to afford a house you can't carry amortized.Get IO rate quotes →
What are the requirements for interest-only loans?
Tighter than conventional: 700+ credit (jumbo IO), 20-30% down, 12-18 months reserves, and income documentation proving you can afford the FULLY AMORTIZED payment — not just the IO payment. Non-QM IO: 620-680 credit, bank statement or DSCR qualification.See non-QM IO options →
Are interest-only mortgages risky?
The 2008 risk was stated-income IO loans. Today's IO loans require full qualification at the amortized payment — the failure mode is different: the payment shock at conversion (typically +25-35%), and you build zero equity during IO unless the home appreciates. Best practice: set your own monthly principal payment anyway; keep IO as the floor, not the plan.Get IO rate quotes →
Can investors get interest-only DSCR loans?
Yes — this is the hottest IO product of 2026. Lima One, Visio, and Kiavi offer 10-year IO DSCR loans: rent qualifies the deal, IO period maximizes cash flow. A $300K DSCR IO at 7.40% = $1,850/mo vs $2,078 amortizing — $228/mo extra cash flow per property.See non-QM IO options →
