The Quick Read: The reset is the base case, not a surprise, so the plan is the exit route plus a reserve built before the interest-only window ends. Interest-only (IO) lifts coverage at the start, but the same rent is later divided by a larger payment. A stock holder can fund that step-up by selling in stages, borrowing against shares, or both, and each choice carries its own tax and margin-call risk.
- On a $4M balance, leverage on a purchase or rate-and-term refinance typically tops out at 65% up to $4,000,000, and at 60% above that size, reviewed case by case and subject to underwriting.
- Interest-only qualification is tested on interest, taxes, insurance and dues (ITIA), with coverage of 0.75 or better through select programs.
- The balance does not shrink during the IO window, so equity grows only if the property appreciates.
- Treat a refinance at the reset as the upside, and hold cash for the downside.
- The stock decision splits in two: what funds the down payment, and what funds the reset.
Key Terms Defined
DSCR (debt service coverage ratio): The property’s monthly rent divided by its monthly debt obligation. The loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines.
ITIA vs. PITIA: ITIA is interest, taxes, insurance and association dues. PITIA adds principal. Interest-only files are tested on ITIA, while fully amortizing files use PITIA.
IO window: The stretch when payments cover interest only. On this ladder, the interest-only period runs up to 120 months.
Reset: The date the loan starts repaying principal, so the payment steps up.
Balloon: A lump sum due at the end of a term instead of gradual repayment.
Concentrated position: A large, low-basis holding in one company’s stock, where selling triggers a big gain.
LTV: Loan-to-value, the loan balance divided by the property’s appraised value.

Why Would a Stock Holder Use an IO DSCR Loan?
Because it lets you buy or refinance a high-value rental without selling the stock first. Selling shares triggers capital gains tax, and holding them keeps your wealth tied to one company.
A $4M rental changes the picture a little. It moves part of your net worth from one company into real property. The loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines, so your stock gains never show up as personal income on the file. Across our wholesale network, entity vesting is welcome, with no layered entities, subject to program terms.
Tax treatment varies by how funds are used and how the property is held; consult a qualified tax professional before relying on any outcome.
What Does a $4M File Actually Look Like?
It is narrower than a standard DSCR file. The standard program stops at $3,000,000, and the super-jumbo ladder carries qualified investors past it. Here are the typical figures through select wholesale programs, all subject to underwriting:
| Band | Purchase / rate-term LTV | Cash-out |
|---|---|---|
| $2M–$3M | 75% | 60% |
| $3M–$4M | 65% | — |
| $4M–$6M | 60% on review | — |
The top cell in the $2M–$3M band needs credit of 720 or better. The top cells in the bands above $3,000,000 need 700 or better. Loans above $3,000,000 also carry an overlay: 0x30x24, 48-month event seasoning, citizens and permanent residents only, no rural property and ten acres maximum. Two appraisals are required above $2,000,000. Reserves are typically six months of ITIA on the subject property (twelve for first-time investors). Cash-out proceeds never satisfy reserves.
A true $4M balance sits at the edge of two bands. A request at exactly $4,000,000 falls in the 65% band, and anything above it is reviewed case by case. Price the deal so the loan lands where you want it.
Which Payment Gets Tested?
On this ladder, interest-only files qualify on ITIA, with coverage of 0.75 or better. Programs elsewhere differ, which is why you ask. Some test the IO payment, some the amortized one. Reserves can be sized the same two ways.
| Payment | What it includes | Question to ask |
|---|---|---|
| IO payment | Interest, taxes, insurance, dues | Is coverage tested here? |
| Amortizing payment | Adds principal | Is it a second test? |
| Post-reset payment | Principal over remaining years | Will my rent still cover it? |
IO does not lower the coverage requirement. It changes which payment the rent is divided by. A DSCR of 1.00 earns full leverage. Coverage from 0.75 to 0.99 is a real path through select programs to $2,000,000 at reduced leverage, though LTV and terms adjust, subject to underwriting. At $4M, plan around 1.00 or better.
Worked Example: Coverage Before and After the Reset
Use ratios, not payments. These inputs are modeled assumptions, not market facts.
1. Assume rent covers the IO payment (ITIA) at 1.25x.
2. Re-amortizing the full balance adds principal. Assume the payment steps up by about 30% on a 10-year IO on a 30-year note, so only 20 years remain to repay everything.
3. Divide the same rent by the new payment: 1.25 ÷ 1.30 is roughly 0.96x.
Same rent, same property, and coverage now sits just under 1.00x. A 1.25x file at closing becomes a sub-1.00 file at the reset. That is why you stress-test at the start, not at month 118.
The mechanism is simple. When the window ends, you can pay in a lump sum, refinance if refinancing is available, start paying down the balance at a higher payment, or sell the property. Those are your four exits, compared in a table below.
What Happens on the Reset Date?
The whole $4M balance re-amortizes over the years left. A 10-year IO on a 30-year note leaves 20 years, so the step-up is sharper than on a fresh 30-year loan. On a fixed-rate note, only the payment type changes. On an adjustable note, the end of IO and the first rate change can land on different dates, which means two dates to track.
Do not count on a mailed reminder. DSCR loans are business-purpose, so you track the date yourself.
The Reset Calendar
| Time before reset | Decision point |
|---|---|
| 36 months | Re-run coverage on the post-reset payment |
| 24 months | Set the stock-sale schedule; review the old note’s prepayment terms |
| 12 months | Order a rent and value check; start the refinance prep |
| 6 months | Confirm reserves are liquid and seasoned |
Refinancing out of a DSCR loan can trigger a step-down prepayment penalty, and a new loan usually starts a new penalty clock. Know the date your penalty steps down.
Four Exit Paths Compared
| Path | What must be true | Main risk |
|---|---|---|
| Hold and absorb | Cash and rent cover the step-up | Coverage near or under 1.00x |
| Refinance | Credit, value and rent hold up | Appraisal comes in low |
| Sell the property | Equity exceeds costs | Market timing |
| Pay down | Stock proceeds are available | Tax bill on the shares |
A refinance is a new underwrite. The new lender runs a fresh appraisal, recalculates coverage and checks credit. On a $4M balance, the leverage tier at that future date may differ from today’s, and cash-out is not available above $3,000,000.
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.
Funding the Step-Up From the Stock
Treat the down payment and the reset reserve as separate decisions. Wealth managers describe several routes: selling a portion over time, exchange funds, borrowing against shares and gifting. Here is how each fits:
- Staged sales. Selling shares realizes a gain equal to the sale amount minus your adjusted basis, and IRS Topic 409 separates long-term holdings (more than one year) from short-term ones. Spread sales across tax years, and time them to land before the reset so cash is ready if the refinance falls through.
- Pledged shares. A securities-backed line of credit lets you borrow against shares and keep the stock. FINRA lists the risks: unintended tax consequences, a possible forced sale, and market volatility magnifying losses. The SEC and FINRA joint investor alert adds that a borrowing may avoid capital gains tax because you do not liquidate, but a drop in collateral value can force you to find money fast or lose your positions.
- Gifting. The recipient owes the capital gains tax on sale, so the tax does not vanish.
Here is the catch with pledging. A concentrated pledged position is the worst case, because one stock’s drop can trigger a call on the entire line. If that line funds your reserves, a call at the wrong time breaks the plan. Use a pledged line as a bridge, not permanent funding.
Source of funds matters too. Cash from a stock sale needs a paper trail, and reserves must be liquid on the subject property. Cash-out from the loan itself never satisfies reserves above $3,000,000.
Where Large Balances Narrow the Options
Availability tightens as size grows. Short-term-rental files stop at $2,000,000, and no-ratio files, through a handful of lenders in the network and subject to underwriting, stop there too. At $4M, you are on the standard 1.00-coverage track with a 120-month interest-only period, and the leverage ladder above sets your ceiling. The credit floor is 660 on the program, but 700 applies above $3,000,000, and a lower score takes a lower leverage cell.
For the full picture of how these programs fit together, see the complete DSCR loans guide. Lendmire’s piece on super jumbo IO reset options for a concentrated-stock borrower using a pledged line goes deeper on the pledged-asset side.
Common Mistakes
- Thin coverage at the start. A file at 1.05x on ITIA is a sub-1.00 file after the reset.
- Ignoring the penalty. Escaping the old note can cost you.
- Treating a pledged line as safe. It carries tax and call risk.
- Assuming exchange funds erase the tax. They only defer it.
- Tracking one date on an adjustable note. There may be two.
Questions to Ask Any Lender Before You Apply
1. Is coverage tested on the IO payment or the amortized payment?
2. Are reserves sized on ITIA or PITIA?
3. What is the longest IO period, and is a 40-year amortization offered?
4. What is the prepayment structure, and when does it step down?
5. Is the leverage tier at my size reviewed case by case?
Frequently Asked Questions
Can I extend the interest-only period?
Not as a matter of course. The window is set at origination, and an extension generally means a new loan and a new underwrite. That brings fresh appraisal, coverage and credit review, plus possible prepayment cost on the old note.
Does interest-only relax the other requirements?
No. It changes which payment the rent is divided by, not the credit, reserve or appraisal rules. Above $3,000,000 the overlay still applies, and above $2,000,000 two appraisals are typical, all subject to underwriting.
Can I refinance into another IO term?
Sometimes, through select programs, if the new file meets coverage, credit and leverage at that time. It is a fresh approval, not a renewal. Cash-out is not available above $3,000,000.
What if rent falls before the reset?
Coverage drops on the same payment, and a refinance gets harder. Hold reserves for the shortfall, and re-run coverage at 36 and 24 months out so you see it early.
Do I have to sell the stock?
No, but you do have to plan how to fund the reserve and any step-up. Staged sales, an exchange fund or a pledged line each shift the tax or margin risk. A qualified tax professional can sort out which fits.
