The Quick Read: An interest-only reset is the point where a super jumbo DSCR loan stops charging interest alone and starts paying down principal, so the payment steps up. You have four ways to handle it: let it convert, pay down principal ahead of time, refinance, or sell the property. Concentrated stock matters because it can fund reserves and paydowns, but it can also become a risk when it backs other borrowing.
- The reset is a scheduled step-up in payment, not a balloon due all at once.
- On the programs in Lendmire’s network, interest-only runs 120 months on 30- and 40-year terms, up to 75% leverage, subject to underwriting.
- The loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. Your stock is not the income source.
- A refinance before the reset is never guaranteed. It is a new loan that has to qualify on its own.
- Test the deal at the fully amortizing payment before you sign, not after.
Key Terms Defined
Interest-only (IO) period: The stretch of years when your payment covers interest, taxes, insurance and dues, but no principal.
Reset: The scheduled date an interest-only loan converts to amortizing, so principal is paid down over the remaining term. The payment rises even if nothing else changes. A reset is not the same as a recast, which is a separate event.
ITIA: Interest, taxes, insurance and association dues. It is the payment a lender tests on an interest-only loan. PITIA adds principal.
Super jumbo: A market label for very large loan balances. No regulator sets a DSCR loan-size ceiling. Each program sets its own tiers.
Concentrated position: A portfolio where one stock makes up a large share of your wealth.
Securities-based line of credit (SBLOC): A credit line secured by the stocks and bonds in a brokerage account.
DSCR (debt service coverage ratio): Monthly rent divided by the lender’s test payment. A reading of 1.00 means rent equals the payment.

What Does “IO Reset” Actually Mean?
An IO reset is the date your interest-only window ends and the loan converts to amortizing payments. It is not a formal product name. Lenders say recast, conversion or step-up. Borrowers use “reset” to cover both that scheduled conversion and any move they make beforehand, such as a refinance.
The key point is that the reset is not a balloon. Your full balance does not come due. The loan simply starts amortizing over whatever term remains.
Here is the shape. On the programs we place files with, interest-only runs 120 months on 30- and 40-year terms. A 30-year term with 10 interest-only years leaves 20 years to repay the whole balance. A 40-year term leaves 30. Scotsman Guide describes the same non-QM structure: a 40-year loan with interest-only payments for the first 10 years before converting to a 30-year fixed-rate loan. So “40-year IO” does not mean 40 years of interest-only. Ten years is the window.
Shorter remaining term, same balance, bigger payment. That is the whole mechanic. The jump is steeper on a 30-year loan than on a 40-year loan, because the 30-year squeezes the balance into 20 years instead of 30.
How Does Underwriting Treat an Interest-Only Super Jumbo DSCR Loan?
Underwriting starts with the property. The loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. On an interest-only file, the test payment is ITIA, so the coverage ratio looks stronger than it would on a fully amortizing payment.
Step by step, here is what the file looks like across our network:
1. Coverage test. Coverage of 1.00 earns full leverage. Interest-only programs run to 75% maximum leverage and look for coverage of 0.75 or better, qualified on ITIA, subject to underwriting. Programs that accept coverage between 0.75 and 0.99 exist through select lenders in the network, and LTV and terms adjust, subject to underwriting.
2. Size ladder. Leverage steps down as the balance rises. On an investment property purchase, ceilings run 80% to $1,000,000, 75% from $1,000,000 to $3,000,000, 65% from $3,000,000 to $4,000,000, and 60% from $4,000,000 to $6,000,000, reviewed case by case. Interest-only caps at 75% regardless.
3. Credit. The program floor is 660. Above $3,000,000, the super jumbo overlay raises it to 700, with 0x30x24 housing history, 48-month event seasoning, and citizens and permanent residents only.
4. Reserves. Six months of ITIA on the subject property, and twelve for first-time investors. Cash-out proceeds never satisfy reserves above $3,000,000.
5. Appraisals. Two appraisals above $2,000,000.
6. Vesting. Entity vesting is welcome, with no layered entities, subject to lender program eligibility.
The honest catch: some lenders test only the interest-only payment, and others also check that the deal works at the amortizing payment. That one detail can decide a marginal file. Where a lender tests the amortizing payment, interest-only adds no qualifying help. Ask which test applies before you pick a program. Our complete DSCR loans guide covers the basic coverage math if you are newer to it.
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.
Where Does Concentrated Stock Actually Enter the Deal?
Your stock does not produce the qualifying income. The property does. But the stock shows up in four places.
- Reserves. The six months of ITIA on the subject property has to be verified in assets. A brokerage account can serve, though how a lender treats a single-stock position (haircuts, restricted shares) varies by program. Plan on a conversation, not an assumption.
- Down payment and closing funds. This is where most borrowers feel the stock. Selling a large embedded gain to fund a down payment may trigger a taxable event. Tax treatment varies; consult a qualified professional.
- Cash-out. A refinance can pull equity from the property rather than from the stock. Cash-out runs 75% to $1,000,000 and 70% from $1,000,000 to $1,500,000. It is 60% from $1,500,000 to $3,000,000, and there is none above $3,000,000. A $1,500,000 cap applies to proceeds above 60% LTV, and cash-out never satisfies reserves above $3,000,000.
- Alternatives for qualifying on assets. Asset-based mortgages exist, and Scotsman Guide notes that asset depletion mortgages can turn idle brokerage and retirement balances into attributed income. That is a separate program from DSCR, with its own guidelines.
Borrowing Against the Stock: The Risk Nobody Prices
Some borrowers fund the down payment with a securities-based line of credit instead of selling. It avoids a sale, but it is a different kind of debt. The DSCR loan is a term loan secured by the property. An SBLOC is secured by your shares.
The SEC and FINRA investor alert on securities-based lending warns that when a portfolio is concentrated in one stock or sector, a single market event could cause the portfolio value to drop precipitously and trigger a maintenance call. The practical lesson: a falling stock can force you to put up cash or sell shares, and that can happen just as your reset date arrives.
Whether a given program allows borrowed down-payment funds, or counts SBLOC draws toward reserves, is a program-level question. Confirm it before you rely on it.
What Happens at the Reset Itself?
On the date the interest-only window ends, your original balance starts amortizing over the shorter remaining term. The payment rises. Practitioner commentary describes step-ups in a wide range, so treat any single percentage as illustrative. What you can count on is the direction and the cause: no principal was paid for ten years, and now it has to be.
Three things follow.
Your coverage ratio drops. The better ratio you enjoyed was a feature of the interest-only window. After reset, the test payment includes principal, so coverage trends back toward what a fully amortizing loan would have shown.
Cash flow tightens. Clearing 1.00 never meant positive cash flow. Coverage compares rent to the lender’s test payment only, not to your vacancy, repairs or management costs.
Stacked dates stack the pain. If you hold several interest-only loans that were originated in the same year, they all reset together. Staggering origination dates softens the combined step-up. Our network permits up to 20 financed properties.
A Modeled Example
Picture a luxury rental that qualifies at roughly 1.10x on the interest-only payment. This is a modeled assumption, not a market figure. At reset, the principal line joins the test payment. Unless rent has grown meaningfully, coverage can land near or below 1.00x on the same property, and on a luxury rental that rents for a small slice of its price, the drop can be sharp.
That is why you model the amortizing payment on day one. If the post-reset ratio sits below 1.00x, a refinance at that point would run through programs that review sub-1.00 coverage, where LTV and terms adjust, subject to underwriting. It would not be automatic.
Your Reset Paths Compared
You have more than one move. Here is how they differ.
| Path | Payment effect | Underwriting needed | Main risk |
|---|---|---|---|
| Let it convert | Steps up on schedule | None | Tight coverage |
| Paydown and recast | Lower than full step-up | Lender-dependent | Uses liquidity |
| Refinance | Resets terms | Full new file | Not guaranteed |
| Cash-out refi | New balance, new term | Full new file | Leverage limits |
| Sell | Ends the loan | None | Taxable gain |
Let it convert. Works when rent has grown and your cash flow absorbs the step-up. No new approval is needed.
Paydown and recast. You make a lump-sum principal payment and ask the lender to re-amortize. Whether a recast is offered is a lender decision, not a right. Confirm it is allowed before you plan around it.
Refinance. A new loan replaces the old one only if the property, your credit and the coverage ratio qualify at that time. Refinance availability is never guaranteed. On a refinance with a rate-and-term purpose, ceilings match the purchase ladder, subject to underwriting. The bank statement alternative is a different route if your income is better documented through deposits than through the property.
Cash-out into a new IO term. This can reopen the interest-only runway, within the cash-out leverage limits above. It also restarts the clock.
Sell. Sometimes the right answer. If the reset coincides with a strong market, selling the property ends the step-up entirely.
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.
How a Concentrated-Stock Borrower Should Choose
The right path depends on what your stock is doing, not just the property.
| Your stock situation | Leaning to consider | Watch for |
|---|---|---|
| Large gain, expecting a liquidity event | Let it convert, then pay down | Timing of the event |
| Stock has run up, holding long | Refinance or cash-out | Don’t pledge the same shares twice |
| Stock has dropped | Preserve cash, avoid new SBLOC | Maintenance-call risk |
| Vesting schedule ahead | Stagger paydowns | Lockups and blackout windows |
The common thread: don’t let one stock fund your down payment, back your credit line and cover your reset at the same time. That stacks risk in a single place. Tax treatment varies; consult a qualified professional before you decide whether to sell, borrow or hold.
A Pre-Reset Countdown
Twenty-four months out. Run the amortizing payment against current rent. Pull rent comps. Ask your lender whether it permits recasts.
Twelve months out. If coverage is thin, decide between paydown, refinance or sale. Check your credit, since refinance programs at higher balances want 700 and above.
Six months out. Line up appraisals (two above $2,000,000) and gather reserve statements. Confirm entity documents are current.
Three months out. Submit the refinance file if you are going that route. Don’t wait for the reset notice. Business-purpose loans may not carry the consumer-style payment-change warnings you might expect, so keep your own calendar.
Where the General Rule Breaks
Short-term rentals. Qualification runs on twelve months of operating history on a refinance, or the appraisal’s short-term-rent analysis on a purchase, at 80% of gross. These files are limited to $2,000,000 and require coverage of 1.00 or higher. Short-term rental rules can vary by city, county, HOA, and property type, so investors should confirm local rules before relying on projected rental income.
Your own use. A beach or ski home you plan to occupy for more than 14 days a year does not count as non-owner-occupied under CFPB Regulation Z. It belongs in consumer-credit territory, not a DSCR loan.
Business purpose is not a free pass. Larger transactions point toward business purpose, as the OCC’s Comptroller’s Handbook on the Truth in Lending Act notes with a $5 million real estate example. But it doesn’t change what a lender requires of you.
Above $4,000,000. Every request is reviewed case by case before submission, purchase or rate-and-term only. Figures above that size are always “on review,” never flat.
Rural and acreage. Rural collateral is excluded above $3,000,000 under the super jumbo overlay, with a ten-acre maximum.
What Nobody Can Promise
No one can promise an extension of the interest-only period. No one can promise a refinance will be available when you want it. Lenders weigh the property’s value, rent and your credit at that moment.
Tell your advisors early. A realistic exit plan, documented before you sign, matters more than any single structure.
Frequently Asked Questions
Can I extend my interest-only period?
Not as a right. An extension, if available, is a lender decision and often means a new loan. Plan for the scheduled reset and treat any extension as a bonus.
Does a lump sum lower my payment automatically?
Not necessarily. A principal payment reduces the balance, but the payment only re-amortizes if the lender offers a recast. Confirm that before wiring funds.
Can I pledge stock instead of selling it?
You can borrow against it, but the debt is secured by your shares and can be called if the stock drops. Whether a DSCR program accepts those funds for down payment or reserves varies by program.
Is a recast the same as a reset?
No. The reset is the scheduled conversion to amortizing payments. A recast is a lender-approved re-amortization after a principal payment. A refinance is a new loan.
What credit score do I need at super jumbo size?
The program floor is 660, and 700 above $3,000,000. Each leverage band wants a higher score for its top ceiling, subject to underwriting.
