The Quick Read: Planning the reset on a $4M super jumbo DSCR loan means treating one date as certain. The balance stays flat through the whole interest-only window, then the payment recalculates over the shorter remaining term, and the coverage ratio you qualified on no longer applies. The work is to test the post-reset ratio early, then choose an exit while you still have options.
- Interest-only on this ladder runs up to 120 months on 30- and 40-year terms, qualified on interest, taxes, insurance and dues (ITIA), subject to underwriting.
- After the reset, coverage is measured on the full payment including principal, so the ratio can fall well below where it started.
- Above $3,000,000 there is no cash-out. The exits are a sale, a rate-and-term refinance, a paydown, or holding through the recast.
- A refinance is a new underwrite on the rent, value and credit you have at that time, not a promise.
- Business-purpose loans typically send no countdown letter, so the calendar belongs to the borrower.
What Actually Changes When the Interest-Only Period Ends
The only thing that changes at reset is the payment structure. The balance does not move, and on a fixed-rate note the interest rate does not move either. Principal payments simply begin, and they are spread over the term that remains.

That last point is where investors get surprised. On a 30-year note with a 10-year interest-only window, 20 years remain at reset, not 30. The payment is sized to retire the full balance in that shorter time. The step-up is sharper than a fresh 30-year loan would suggest.
| Item | During interest-only | After reset |
|---|---|---|
| Principal balance | Unchanged | Falls with each payment |
| Payment covers | Interest only | Interest plus principal |
| Remaining term | Full term minus time elapsed | Same, now fully amortizing |
| Fixed interest rate | Constant | Constant |
| Coverage ratio | Tested on ITIA | Tested on full PITIA |
Taxes, insurance and association dues sit outside the interest-and-principal line. They are in the denominator both before and after the reset, so they do not cause the jump. The jump comes from principal, which enters the payment only after the reset.
Why a $4M Balance Raises the Stakes
A $4M balance makes the reset a large dollar event, but the ratio is what decides your options. The reset happens on a schedule whether or not the market moved, and a high-balance file has fewer lenders and tighter terms waiting if you need to refinance out of it.
Here is how the loan sits on the ladder Lendmire sees across its wholesale network. Through select programs, and subject to underwriting, a purchase or rate-and-term loan between $3,000,000 and $4,000,000 tops out at 65% LTV. From $4,000,000 to $6,000,000 the ceiling is 60% LTV on review, because every request above $4,000,000 is reviewed case by case before submission. Cash-out is not available above $3,000,000. Credit of 700 or better applies above $3,000,000, with 0x30x24 housing history and 48 months of event seasoning. Two appraisals are required above $2,000,000. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.
Coverage matters differently at this size. The paths below 1.00 run only to $2,000,000 through select programs, with LTV and terms adjusting, subject to underwriting. A $4M file is built around coverage of 1.00 or better. That means a reset that pushes the ratio under 1.00 is a real problem, not a rounding error.
Interest-only is available up to 75% maximum LTV with coverage of 0.75 or better, qualified on ITIA. At $4M the leverage ladder, not the interest-only ceiling, is the binding limit. Plan around the ladder.
How the Ratio Moves: A Worked Illustration
Take a file that qualifies at roughly 1.25x on the interest-only payment. This is an illustration, not a market figure. After recast on a 30-year note with a 10-year interest-only window, the same rent can cover the full payment at something under 1.05x. Nothing about the property changed. The denominator did.
The method is simple. Divide your interest-only coverage by the ratio of the new full payment to the old interest-only payment. Ask the servicer for the post-reset payment figure and use theirs. Then test it, as described next.
Stress-Test the Post-Reset Coverage Ratio
Run the test at least a year before the reset, and repeat it as the date nears. A sound test follows these steps.
1. Confirm the post-reset payment. Get the amortizing payment figure and the exact date from the servicer in writing. Check the note for the end of the interest-only period, the amortization term and any balloon wording.
2. Use current rent, not hoped-for rent. Start from the signed lease or the current rent data, and apply a haircut for vacancy or a softer renewal.
3. Refresh taxes and insurance. Use the current bills. Both sit in the denominator, and both tend to drift upward.
4. Recompute coverage. Divide the haircut rent by the full payment plus taxes, insurance and dues.
5. Read the result against your plan.
On the earlier illustration, a 1.04x post-reset ratio with a 10% rent haircut lands near 0.94x. That is the kind of result the test exists to find early.
| Post-reset ratio after haircut | Planning read | Typical action |
|---|---|---|
| 1.15x or higher | Comfortable | Hold, or refinance if it improves the file |
| 1.00x to 1.14x | Borderline | Build reserves, plan a paydown or an early sale |
| Below 1.00x | Needs a fix | Pay down, raise rent, sell, or restructure before the date |
These bands are planning guides, not program thresholds. Lenders set their own, and 1.00x is where full leverage generally begins on the network ladder.
Why Nobody Will Remind You
DSCR loans are designed for non-owner-occupied investment properties. Because they are business-purpose investor loans, they are reviewed differently from a standard owner-occupied mortgage. One practical result is that you should not expect a mailed countdown letter. The date is in your note, and tracking it is your job.
The federal CFPB explainer on interest-only loans is written for consumers, but it states the reset dynamic plainly. The balance does not fall during the interest-only period. At the end you pay it off, refinance if you can, or begin higher payments that retire the balance. Its caution carries over to investors: do not assume you can sell or refinance if the payment rises, because property value or your finances could change. The interagency guidance on nontraditional mortgage product risks calls the step-up payment shock and notes that obligations can increase substantially at the end of the interest-only period.
Reset, Recast and Balloon: Check Your Note
These terms look alike month to month but behave differently. The note controls which one applies to you.
| Term | What happens | Who triggers it |
|---|---|---|
| Scheduled reset | Payment recalculates to amortize the balance | The note, on its date |
| Voluntary recast | Payment recalculates after a lump-sum paydown | You, if the note allows |
| Balloon | Full remaining balance is due at maturity | The note, at maturity |
| Adjustable note | Rate can reset on its own calendar | The note, separately |
Two edge cases deserve attention. On an adjustable note, there can be two dates, one for the interest-only conversion and one for the rate, so both the interest and the future amortized payment can change. On a blanket loan covering several properties, every property in the pool recasts on the same date. Also keep in mind that no network program converts automatically to a fixed payment. Moving off the loan means a new application and a new underwrite under the guidelines in force at that time.
Qualification at closing also differs by program. Lendmire’s network generally qualifies interest-only files on ITIA. Some programs elsewhere in the market test coverage on the fully amortized payment, so the same property can pass on one basis and miss on the other. Ask which basis is used before you choose.
The Reset Calendar
Plan backward from the reset date. The milestones below are planning steps, not loan timelines. The most useful ones are the early ones, because they leave time to act.
| Months before reset | Milestone | Deliverable |
|---|---|---|
| 24 | Confirm date and amortization term | Note and rider reviewed |
| 18 | Run first stress test | Ratio after rent haircut |
| 12 | Check prepayment schedule against the date | Penalty overlay written down |
| 9 | Decide the likely exit | Hold, refinance, sell or paydown |
| 6 | Begin refinance readiness if chosen | Fresh valuation, rent roll, bills |
| 3 | Go or no-go gate | Execute the plan or the fallback |
Practitioners often start acting six to nine months out. That is useful lead time, but it is a habit, not a rule. A $4M balance has fewer refinance lenders and more appraisal risk, so earlier is better.
Choose Your Exit
Each exit has its own prerequisites. Pick the one your numbers support, and keep a second one in reserve.
| Exit | What it needs | Main risk |
|---|---|---|
| Refinance | New underwrite, 1.00x or better, value that supports the balance | Value, rent or credit slipped |
| Sell | A market and a price that clears the loan | Timing against the penalty schedule |
| Hold and absorb | Coverage and reserves for the full payment | Rent growth falls short |
| Paydown or recast | Cash on hand, a note that allows it | Locks up liquidity |
Refinance. A rate-and-term refinance at this size is reviewed on its own merits. Between $3,000,000 and $4,000,000 the ceiling is 65% LTV through select programs, and above $4,000,000 it is 60% on review, subject to underwriting. Because the balance has not amortized, the refinance LTV tracks the original loan unless value has moved. If value dipped, the gap becomes a paydown you fund yourself. Cash-out is not on the table above $3,000,000, and cash-out proceeds never satisfy reserves. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
Across Lendmire’s network, high-balance refinances most often stall on one of three things: a value shortfall on the new appraisals, rent that did not grow as projected, or a credit event after the original closing. A plan that treats the recast as the base case and the refinance as the upside holds up better than the reverse.
Sell. Check the prepayment schedule against the reset date. A sale or refinance before the penalty expires can trigger the remaining charge. Tax treatment varies; consult a qualified professional before relying on any outcome.
Hold. This works if the post-reset ratio clears 1.00x with a cushion and you hold reserves for the higher payment. Reserve requirements vary by file and lender, and they may differ for first-time investors. Your post-reset reserves should be sized to the full payment.
Pay down. A lump sum lowers the balance, and a recast can lower the payment if the note allows it. This is a separate event from the scheduled reset, so confirm the terms before you plan around it.
DSCR vs. conventional financing
There are two common ways to finance an investment property, and they qualify you differently — here’s how investors weigh them.
Why investors choose it
- Qualifies on the property’s rental income — no personal tax returns, W-2s, or pay stubs needed to document income.
- No personal debt-to-income ceiling to clear, so existing mortgages and obligations don’t cap your borrowing the same way.
- Can be closed in an LLC, keeping the property inside a business entity.
- Built for scaling — not held to the limit on number of financed properties that conventional financing applies.
- Underwriting centers on the deal: generally qualifies when the rent covers the payment, a 1.00x coverage ratio being a common baseline (confirmed in underwriting).
- Designed specifically for investment property, including long-term and, where the program allows, short-term rentals.
Where it’s strong
- Often the lowest ongoing financing cost for a buyer who fully qualifies on personal income — a fit for a first property or a cost-first purchase.
Trade-offs for investors
- Requires full personal income documentation and must fit within a debt-to-income limit — salary, existing debts, and other mortgages all count.
- Typically held in your personal name rather than a business entity.
- Caps how many financed properties you can carry, which can become a ceiling as a portfolio grows.
- Evaluates you as a borrower as much as the property, which usually means more paperwork.
How investors usually choose: a first or single property often optimizes for the lowest financing cost; portfolio builders often optimize for leverage, vesting in an LLC, and scaling past conventional caps. The right answer depends on your goals, the property, and current guidelines — both paths run through select lenders in Lendmire’s wholesale network, with eligibility and terms confirmed in underwriting.
What If the Refinance Falls Through?
Write the fallback before you need it. The simplest version has three parts. First, size reserves to cover the higher payment for a defined period. Second, decide in advance what rent increase or paydown would restore coverage. Third, set a sale trigger: if the ratio stays under 1.00x after a set number of months, list the property.
A new interest-only loan can restart the clock, but only through a fresh underwrite. At $4M that means the leverage ladder, the 700 credit overlay, two appraisals and case-by-case review above $4,000,000. Do not plan around it.
Who Interest-Only Fits
Interest-only suits a defined hold or exit horizon, such as a planned sale near the reset. It also suits a property with real rent growth ahead, and an investor who keeps the cash savings in reserve rather than spending them. It fits poorly on a thin-coverage file with no exit plan. If the only way the numbers work is the interest-only payment, the reset is the problem you have deferred, not solved. Entity vesting is welcome on the network, subject to program terms, so ownership structure rarely changes the reset math.
Key Terms Defined
Interest-only period. The stretch of the loan, up to 120 months on this ladder, when scheduled payments cover interest but not principal.
ITIA. Interest, taxes, insurance and association dues, the payment basis on which interest-only files are qualified.
Reset. The scheduled date when payments begin to include principal.
Recast. A recalculation of the payment over the remaining term, scheduled or voluntary after a lump-sum paydown.
Balloon. A maturity clause that makes the full remaining balance due at once.
Post-reset ratio. Monthly rent divided by the full payment with principal, taxes, insurance and dues.

Frequently Asked Questions
Does the interest rate change when the interest-only period ends?
On a fixed-rate note, no. Only the payment structure changes, and principal payments begin. On an adjustable note, the rate can follow its own calendar, so read the note for two separate dates.
Will my servicer warn me before the reset?
Do not count on it. Business-purpose loans typically carry no mailed countdown notice. Put the date on your calendar, and ask the servicer for the post-reset payment figure well ahead of time.
What if I cannot refinance when the period ends?
You hold through the recast or sell. Refinancing is a new underwrite on current rent, value and credit, so it is never assured. Build reserves and a sale trigger into the plan from the start.
Does a lump-sum paydown lower my payment?
Only if the note allows a recast after the paydown. Voluntary principal payments are commonly allowed during the interest-only period, but a lower payment depends on the recast terms. Confirm both before you rely on it.
Can I roll into a new interest-only loan to restart the clock?
Possibly, but it is a new application and a new underwrite. At this size the leverage ladder, credit overlay, appraisals and review above $4,000,000 all apply again, subject to underwriting.
