The Quick Read: Interest-only suits a founder who wants cash kept liquid and a clear exit plan. Amortizing suits a founder who plans a long hold and wants the balance falling from day one. Which one fits depends on how long you hold, what you do with the freed cash, and which payment the program uses to test coverage.
- Interest-only changes the payment used in the coverage ratio. It does not change credit, reserves, or leverage limits.
- Through select wholesale programs, interest-only runs 120 months on 30- and 40-year terms, to 75% LTV, with coverage of 0.75 or better, subject to underwriting.
- Sale proceeds must be sourced and documented. After an exit, the paper trail often decides the file more than the loan structure does.
- The balance does not fall during the interest-only period, and the payment steps up when amortization begins.
Side-by-Side
The table below describes how the two structures are generally built. The amortizing column reflects published industry norms. The interest-only column reflects the select programs in Lendmire’s wholesale network, subject to underwriting.

What Is Actually Different Between the Two?
Interest-only and amortizing are payment structures. They are not different ways of qualifying. In both cases the loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines.
The difference sits in the denominator. On an amortizing loan, the coverage ratio divides rent by PITIA. On an interest-only loan, the program typically divides rent by ITIA, which drops the principal line. Same rent, smaller denominator, higher ratio.
Lendmire’s explainer Interest-only DSCR Loan Requirements walks through that same split. It also makes the key point that interest-only does not loosen credit, leverage, or reserve rules.
Here is the catch. Across the wholesale network, a few programs test coverage on the fully amortizing payment even when the loan is interest-only. A property that clears 1.00x on the interest-only payment may miss on that basis. Ask which payment the lender tests before you rely on the interest-only ratio.
Why a Company Sale Changes the Conversation
Qualification on these loans does not use personal income, so a founder with a large, one-time liquidity event is not penalized for having no paycheck. What matters is the property’s rent, credit, and clean, sourced assets.
That makes documentation the real work. Funds for the down payment and reserves must be traceable. A sale agreement, wire confirmation, closing statement, and a prior statement showing the pre-sale balance are the usual building blocks. Lendmire’s page on large deposit sourcing rules covers that paper trail in detail.
A few practical points on sale proceeds:
- Money sitting in a business account or an escrow holdback may not count as liquid. It may need to be documented as accessible, or moved and seasoned.
- An undocumented deposit is generally excluded from the file. It does not automatically sink the loan if other verified funds still cover the requirement.
- Cash-out proceeds from the subject never satisfy reserves on files above $3,000,000.
- Move money cleanly. Shuffling funds between accounts mid-file creates questions you do not need.
Reserves on the subject run six months of PITIA, or ITIA on an interest-only loan, and twelve months for first-time investors, subject to underwriting. There are no extra reserves for other financed properties, and the program allows up to 20 financed properties.
When Interest-Only Is the Better Fit
Interest-only tends to work for a founder in one of these positions. Picture an investor who just exited a company and wants to keep cash flexible for a tax bill, a second acquisition, or a later venture. Keeping principal payments out of the monthly obligation preserves that flexibility.
Say you plan to sell or refinance the property within the interest-only window. The runway on a 30- or 40-year term is 120 months, so a hold of a few years never reaches the step-up. Paying down principal you will hand back at sale is a choice, not a requirement.
It also helps a marginal-rent deal. A property sitting just under the program’s coverage floor on the full payment may clear on interest-only, without adding equity. That is a legitimate use, but treat it carefully. If the deal only works on interest-only, you are relying on the exit plan, not on the property.
The structure has real limits:
- The maximum LTV on interest-only is 75%, and coverage must be 0.75 or better, subject to underwriting.
- The balance does not fall. Equity builds only through appreciation or voluntary paydown.
Interest-only is not negative amortization. Unpaid interest is not added to the balance.
When Amortizing Is the Better Fit
Amortizing is the cleaner choice for a long hold. Principal drops from the first payment, equity builds on a schedule you control, and there is no later payment shock to plan around.
It also fits a founder who wants forced discipline. A fresh liquidity event can tempt a large bet. Amortization quietly turns part of every payment into equity.
Consider a property that clears coverage comfortably on the full payment, say around 1.2x. There is little reason to add step-up risk for a small ratio gain. Where the number already works, the simpler structure usually wins.
Amortizing also removes the question of which payment the lender tests. If the program reviews the file on the full payment anyway, interest-only may not improve the ratio at all.
The tradeoff is cash. Principal payments tie up capital that interest-only would leave free. If you can deploy that cash at a better return than your loan costs, interest-only is the stronger argument. If you cannot name the use, the case is weaker.
How Size Shapes the Choice
Super jumbo means the same mechanics at a larger balance, with tighter limits. Through select wholesale programs, the ladder steps down as the loan grows, subject to underwriting:
| Loan size | Purchase LTV | Cash-out LTV |
|---|---|---|
| $150K–$1M | 80% | 75% |
| $1M–$1.5M | 75% | 70% |
| $1.5M–$2M | 75% | 60% |
| $2M–$3M | 75% | 60% |
| $3M–$4M | 65% | — |
| $4M–$6M | 60%, on review | — |
| $6M–$10M | 60%, on review | — |
The top cell in each band needs a particular score: 660 or better to $1,000,000, 700 or better from $1,000,000 to $1,500,000, and 720 or better from $1,500,000 to $3,000,000. A lower score takes a lower leverage cell inside the same band.
Loans above $2,000,000 need two appraisals. Above $4,000,000, every request is reviewed case by case before submission, and it is purchase or rate-and-term only. Short-term-rental and no-ratio files stop at $2,000,000. Lendmire’s standard DSCR program stops at $3,000,000, and this ladder carries qualified investors past it.
Because interest-only caps at 75% LTV, it does not reach the leverage of a standard purchase at the smaller sizes, but at the larger sizes the ladder already sits at or below that figure. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
The Stress Test Before You Choose
A short test settles most of these decisions. Run it before you pick a structure.
1. Compute coverage on the interest-only payment. This is your closing ratio.
2. Recompute coverage on the fully amortizing payment over the shortened remaining term. This is your post-step-up ratio.
3. Test a weaker-rent year on both.
4. Ask whether the lender tests the interest-only or the amortizing payment.
If the post-step-up ratio falls well below 1.00x, you are betting on a sale, refinance, or paydown. That can be a sound bet. It should be a named bet, with a date, not a hope.
A voluntary lump-sum paydown can recast the payment before the scheduled step-up. Whether a given program allows it is a term-sheet question, not an assumption.
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.
The Tax Misconception After a Company Sale
One idea comes up often: using a rental purchase to shelter the gain. A 1031 exchange applies only to real property held for business or investment. The IRS instructions for Form 8824 state that like-kind treatment is limited to that kind of real property. Proceeds from selling a company’s stock or operating assets are generally not eligible. Tax treatment varies by situation; consult a qualified professional before relying on any deduction or deferral.
Business-Purpose Framing
These are business-purpose investor loans, so they are reviewed differently from a standard owner-occupied mortgage. The Federal Register’s final rule on ability-to-repay standards treats investment-purpose loans as business-purpose credit, outside the consumer ability-to-repay provisions. In practice, terms are set by program guidelines, so compare actual structures rather than assuming they match.
Where the General Rule Breaks
A few edge cases are worth knowing:
- Entity versus guarantor. Vesting in an LLC is welcome, subject to program terms, but a personal guarantee is typical. The entity does not remove personal exposure.
- Short-term rentals. Coverage of 1.00x or higher is required, income runs at 80% of gross, and the borrower must be experienced. Municipal permission to operate must be documented per property. Short-term rental rules can vary by city, county, HOA, and property type, so confirm local rules before relying on projected rental income.
- Sub-1.00 coverage. Select lenders in the network do review coverage from 0.75 to 0.99 at reduced leverage, with LTV and terms adjusting, subject to underwriting. That is a structure to justify, not a shortcut. If a deal only works below 1.00x, revisit the property before the loan type.
- Credit tiers. The program floor is 660 on loans to $3,000,000. Above $3,000,000 a 700 floor applies, along with a 0x30x24 housing history and 48-month event seasoning. A lower score takes a lower leverage cell, subject to underwriting.

Pre-Application Checklist
- Which payment does the program use to test coverage?
- How long is the interest-only period, and what is the remaining amortization term afterward?
- What is the post-step-up coverage on the base case and a weaker-rent case?
- Can the sale proceeds be documented and shown as accessible?
- What is the planned exit, and what happens if it slips?
- Does a voluntary recast apply on this program?
If the exit slips, your options are a refinance, a paydown, or a sale on a different timeline. None of them is guaranteed, so size the file for the case where the exit is late.
Choosing by Profile
- Selling the property within a few years: interest-only usually fits.
- Holding long term for income: amortizing usually fits.
- Wanting cash for another deal: interest-only, if the use of cash is concrete.
- Wanting forced savings: amortizing.
- Rent barely clears on the full payment: re-examine the property first, then decide.
Neither structure is better in the abstract. It comes down to your hold period, your discipline with freed cash, and your tolerance for a later step-up.

Frequently Asked Questions
Does interest-only make it easier to qualify on a super jumbo DSCR loan?
It can raise the coverage ratio, because the program divides rent by a smaller payment. Interest-only caps at 75% LTV with coverage of 0.75 or better, subject to underwriting. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.
What happens when the interest-only period ends?
The payment is recalculated to repay the unchanged balance over the remaining term. After 120 months on a 30-year loan, that is 20 years, so the payment steps up. Plan the exit or paydown around that date.
Can I use company-sale proceeds for the down payment and reserves?
Generally yes, if the funds are documented and accessible. Expect to provide a sale agreement, wire confirmation, and a statement showing the pre-sale balance. Funds in a business account or escrow holdback may need to be moved and seasoned first.
Does an LLC protect me from personal liability?
Not by itself. Entity vesting is welcome on these loans, subject to program terms, but a personal guarantee is typical. Do not assume the entity removes your exposure.
Is interest-only the same as negative amortization?
No. Standard interest-only leaves the balance unchanged. Negative amortization adds unpaid interest to the balance, which is a different product.
