Choose ARM Vs Fixed On An Asset Depletion — The Quick Read: The rate structure and the qualification method are two separate decisions. Asset depletion turns your liquid assets into a qualifying income figure. ARM or fixed decides how your payment behaves later. Pick based on hold period, reserve cushion, and how thin your coverage figure already is — not on which one looks cheaper on day one.
Most borrowers walk into this decision thinking it’s one choice. It isn’t. One question is: how does the lender turn your bank balance into income? The other is: what happens to your payment five or seven years from now? Answering the first question does not answer the second. That’s where a lot of high-net-worth borrowers get tripped up.
Key Takeaways
- Asset depletion converts liquid assets into monthly qualifying income using a divisor — the choice of ARM or fixed doesn’t change that math.
- A fixed-rate loan holds one payment for the full term; an ARM resets after an initial period using an index-plus-margin formula.
- Loan size gates your options — fixed availability through a portfolio non-QM program generally runs to $6,000,000, with a separate bank-portfolio ladder carrying twelve-month-statement files to $30,000,000.
- Reviews above $4,000,000 happen case by case before submission on every leverage tier.
- The riskier side of an ARM reset usually lives wherever payment sensitivity is thinnest in the file — the property’s rent coverage, the borrower’s asset cushion, or both.
Key Terms Defined
Asset depletion (also called asset utilization): a qualification method that divides a borrower’s liquid assets by a fixed number of months to produce an imputed monthly income figure, used in place of traditional personal-income documentation or pay stubs.
Residual income: a dollar-cushion test that nets qualifying income against the proposed housing payment and other obligations, producing a leftover amount rather than a ratio — a structurally different concept from a DTI-style calculation.
ARM (adjustable-rate mortgage): a loan that holds an initial rate for a set period, then recalculates periodically using an index plus a margin, subject to rate caps.
Fixed-rate mortgage: a loan that holds one note rate for the entire term, so the payment never changes because of rate movement.
DSCR (debt-service coverage ratio): a measure of whether a property’s rent covers its full monthly obligation — Lendmire’s complete DSCR loans guide walks through the mechanics in more depth.
Interest-only (IO) period: a stretch of the loan term where the payment covers only interest, taxes, insurance, and dues — no principal reduction, which changes the coverage math if the loan later amortizes.
How Loan Size Gates Your Options
Loan size decides whether fixed is even on the table, and that gate matters more than most borrowers realize going in. Across the wholesale programs Lendmire places files through, a portfolio non-QM bank-statement program carries loans to $6,000,000, while a separate bank-portfolio program built for twelve-month-statement borrowers runs its own ladder to $30,000,000 — 65% at or below $5,000,000, 60% to $10,000,000, and 55% up to $30,000,000, with interest-only capped at 60% or the band’s ceiling, whichever is lower.
Leverage on a primary residence steps down as the loan grows: typically 90% to $1,000,000, 85% to $1,500,000, still 85% through $2,000,000, then 80% through $2,500,000 and $3,000,000, and down to 75% at the top credit tier through $3,500,000. Above that, every file moves to case-by-case review before submission — never assume a flat ceiling applies once you cross $3,500,000 to $4,000,000. Second homes and investment properties generally run about five points lower at every size band, subject to lender guidelines.
This matters for the ARM-vs-fixed question because the two structures aren’t always priced or offered the same way at every size. A borrower at $1.2 million has a wide menu. A borrower at $8 million is already inside case-by-case territory on the bank program’s own ladder, where the structure decision gets folded into a broader underwriting conversation rather than a simple menu pick.
The Decision Framework
The framework comes down to three questions: how long do you plan to hold the loan, how much cushion do you have if the payment moves, and which side of your file — the property or your personal asset base — is thinner on coverage. Answer those honestly before comparing rate structures.
Hold period and exit certainty. A borrower planning to sell or refinance well before an ARM’s first adjustment carries very different risk than one planning to hold for fifteen years. The catch: business-purpose and asset-based loans set prepayment terms independently of the ARM’s adjustment schedule. The prepayment window and the first reset date don’t automatically line up, so a plan to exit before adjustment needs to check both dates, not just one.
Reserve cushion and residual position. Reserves on files through Lendmire’s network typically run three months of payments to $500,000 in loan amount, six months to $1,500,000, and nine months above that — plus two months per additional financed property, up to a twelve-month maximum, and a full twelve months for first-time investors. That reserve cushion is the practical buffer that absorbs a payment increase if an ARM resets higher. A thin reserve position paired with an ARM is a stack of two risks in the same direction.
Which side of the file is thinner. This is the part almost nobody explains clearly. When a rental property is qualified on its own rent-to-payment coverage — a DSCR file — an ARM reset changes the debt-service side of that ratio directly. Coverage recalculates against the new payment. But a borrower’s personal asset-depletion or residual figure doesn’t move when the rate resets; only the payment being tested against that fixed number changes. Investor and DSCR loan production has grown from roughly 22% of non-QM output to about 35% over a recent multi-year stretch according to Scotsman Guide, so more borrowers now run exactly this dual-track structure — personal qualification on one side, property coverage on the other — and the two don’t behave the same way when a rate adjusts.
Are you combining a personal asset-based qualification with a separately DSCR-qualified rental? If so, figure out which side has less room before you assume an ARM’s lower starting payment gives you free cushion. Sometimes the property has less room. Sometimes the personal side does. Rarely does neither side have tight room.
Structure-Specific Mechanics
| Factor | Fixed-Rate | ARM |
|---|---|---|
| Payment behavior | One rate for full term | Fixed period, then resets on index + margin |
| Reset exposure | None | Recalculates at each adjustment date, within caps |
| Index/margin | N/A | Set at closing; margin never changes after closing |
| Best fit for | Long hold, thin cushion | Short hold, strong reserves |
| Loan size availability | Portfolio program to $6M | Available through both programs, incl. Bank ladder to $30M |
A fixed-rate loan carries no reset exposure at all — the payment tested against your qualifying income on day one is the same payment tested against it in year fifteen. An ARM holds an introductory rate, then recalculates using an index plus a margin the lender sets at closing; that margin is fixed for the life of the loan, but the index component moves with market conditions. Interest-rate caps limit how far any single adjustment can move the rate, and a lifetime cap limits total movement over the full term — but neither cap eliminates the possibility of a materially higher payment down the road.
The Ability-to-Repay rule under Regulation Z requires a lender to verify the income or assets it uses to qualify a borrower, per Consumer Financial Protection Bureau guidance. This rule is the legal foundation that lets asset-based income exist at all. But it says nothing about which rate structure fits your situation. You and the lender underwriting the file make that decision together.
Interest-only options add another layer. Through the portfolio program, IO runs to 85% LTV with a 700 credit floor on a 40-year term carrying a 10-year IO period; the bank program allows IO to 60% LTV on 5- and 7-year fixed-period adjustables (a 10-year fixed-period adjustable there is fully amortizing instead). An IO period paired with an ARM means the payment being tested only reflects interest, taxes, insurance, and dues at closing — it says nothing about what happens once the loan starts amortizing or the rate resets, whichever comes first. That’s a meaningfully different exposure than a fixed, fully amortizing structure carries from day one. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
Special Cases Worth Knowing
Sole-source versus layered qualification. Some asset-based programs require the asset-derived income to stand alone; others allow stacking it with rental income, a pension, or part-time wages. A layered file generally has more cushion to absorb an ARM’s post-reset payment than a sole-source file sitting near its qualifying edge — worth checking before assuming the two files carry equal ARM risk.
Retirement-account treatment. Retirement assets typically count at 70% of vested value for the asset-allowance calculation, rising to 80% once a borrower reaches 59½ — an adjustment that shrinks the effective qualifying figure independent of whichever rate structure you pick.
Divisor choice and standalone qualification. Through Lendmire’s network, the asset-allowance path runs on a 36-month divisor as a supplemental income source when DTI sits at or below 60%, a 60-month divisor when DTI runs above 60%, or an 84-month divisor when the asset income stands alone or the loan amount exceeds $3,500,000 — primary and second homes only, capped at 80% LTV. A separate assets-only path skips DTI entirely, requiring liquid U.S. assets equal to the loan amount plus closing costs plus sixty months of any net loss carried on other residential property. These are two structurally different tests, and which one your file runs under changes how much room you have to absorb an ARM reset. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
Property collateral and rent support. When a rental property sits alongside personal asset qualification, appraisers typically support the rent figure using the same forms agency lenders rely on even in a non-QM file — the Form 1007 comparable rent schedule for single-family investment property, per Fannie Mae, remains the industry-standard mechanism for that rent opinion, even though the loan itself never touches agency guidelines. If you’re weighing how a large asset-based file handles rate structure alongside heavier leverage, Lendmire’s writeups on how lenders choose ARM versus fixed on a large loan and on choosing ARM versus fixed on a super-jumbo cover adjacent ground worth a look.
Non-QM borrowers as a group carry credit profiles closer to conventional borrowers than most people assume — average FICO scores around 776 with average LTVs near 75% on recent vintage originations, per Scotsman Guide — so this is not a corner of the market reserved for weaker files. It’s a documentation path, not a credit-quality signal.
Common Misconceptions
People often treat asset depletion and residual-income qualifying as the same thing. They’re related, but they work differently. One produces a ratio from imputed asset income. The other nets that income against your obligations to produce a dollar cushion, with no ratio at all. If you confuse the two, you end up comparing files that aren’t actually comparable.
Here’s another common mix-up: people assume the ARM-versus-fixed decision and the income-documentation method are the same choice. They’re not. One proves your repayment ability at origination. The other determines how that proven payment behaves over time. A file can be strong on the asset side and still carry real exposure on the rate-structure side.
This is not legal or tax advice. Program terms also shift as lenders adjust their guidelines. If you’re weighing this decision on a specific file, confirm current terms with a lender. You should also talk to a qualified tax or legal professional about your own situation before you commit to a structure.
Frequently Asked Questions
Does choosing an ARM change how my asset depletion income is calculated?
No. The divisor, the eligible asset types, and the resulting qualifying income figure are set independently of the rate structure. ARM or fixed only affects what payment that qualifying income gets tested against, both at closing and after any reset.
Is fixed-rate financing available on every asset depletion loan size?
Not automatically. Through Lendmire’s network, fixed structures are generally available through the portfolio program to $6,000,000, with a separate bank-portfolio ladder carrying twelve-month-statement files to $30,000,000 on its own terms. Everything above $4,000,000 is reviewed case by case before submission, subject to lender guidelines.
Can I combine asset depletion income with rental income from a DSCR property?
Some programs allow layering asset-derived income with rental, pension, or part-time wages; others require the asset calculation to stand alone. Which structure applies changes how much cushion you have if an ARM resets, so it’s worth confirming which path a specific file falls under before comparing rate structures. Lendmire’s dscr-loan-vs-asset-depletion-loan breakdown covers how the two income methods interact.
Does an ARM reset affect a rental property’s DSCR the same way it affects my personal residual figure? No. A property’s DSCR recalculates directly against a new debt-service number when an ARM resets. A personal asset-depletion or residual figure stays static — only the payment being tested against it changes. The two react to the same rate event in different ways.
How do retirement account balances factor into the asset depletion divisor?
Retirement assets typically count at 70% of vested value, rising to 80% once the borrower reaches 59½, before entering whichever divisor applies to the file. That haircut applies regardless of which rate structure is ultimately chosen.
