The Quick Read: A private bank adjustable loan fits a borrower who wants one institution to hold both the portfolio and the mortgage, and who expects to sell or refinance before the first reset. A non-QM fixed loan fits a borrower who wants a stable payment for a long hold and wants financing kept separate from custody. At a $3.5 million scale, the qualification path often matters more than the payment structure, and that path depends on how the property will be used.
- A private bank ARM usually underwrites the whole relationship, while a non-QM fixed loan underwrites deposits, assets, or property cash flow.
- Asset-based paths in Lendmire’s network cover primary and second homes only, so an investment purchase usually runs on bank statements or property income.
- The fixed structure removes reset risk. The adjustable structure can shift the payment after the initial period.
- A pledged-asset ARM can carry collateral-call risk that a plain fixed loan does not.
- Above $4,000,000 every file is reviewed case by case before submission.
The Honest Answer First
Neither option wins on its own. They solve different problems.
A private bank ARM is for the borrower whose wealth already sits at the bank and who values one relationship. The bank looks at total assets and may layer in a pledge. That can make sense on a short hold, or when the borrower plans to refinance or sell before the initial period ends.
A non-QM fixed loan is for the borrower who wants certainty over the full hold and does not want financing tied to custody. Through select wholesale programs, it is reviewed on documented deposits, on assets, or on property cash flow, subject to full underwriting.
An AUM-based borrower often has high net worth and modest taxable income. Both paths can work for that profile. The real question is which one fits the property use, the hold period, and the tolerance for a payment that can change.
The private bank column below shows published industry norms, which vary by institution. The non-QM column reflects typical guidelines of select programs in the network, subject to full underwriting. Nothing here is a commitment to lend.
Side-by-Side
| Factor | Private bank ARM | Non-QM fixed |
|---|---|---|
| Review basis | Whole relationship and total assets | Deposits, assets, or property rent |
| Documentation | Fuller personal financial picture | Statements, asset records, or lease evidence |
| Property types | Set by the bank’s credit policy | Set by program, with overlays at this size |
| Entity vesting | Varies by bank | Often possible, subject to program terms |
| Reset exposure | Payment can change after initial period | None during the term |
| Collateral terms | Pledge may require top-ups | No pledge needed |
| Reserves | Often judged against relationship assets | Months of reserves, rising with loan size |
| Custody | May be tied to keeping assets at the bank | No move of custody required |
Read the table as two different underwriting philosophies. One treats you as a client. The other treats you as a file.
How an AUM Borrower Actually Qualifies Through Non-QM
Start with the path, then the structure. Across the wholesale network, three routes serve high-net-worth borrowers whose traditional personal-income documentation understates what they can carry.
Bank statements. The lender reviews 12 or 24 consecutive months of personal or business deposits. Business statements need at least 25% ownership. Qualifying income is eligible deposits divided by the statement months, after an expense ratio. Transfers from the borrower’s own business into a personal account count in full. A profit-and-loss method exists too, capped at 80%.
Asset allowance. Liquid assets are divided by 36, 60, or 84 months to create supplemental or standalone income. The 84-month divisor applies to standalone use and to any loan above $3,500,000. It covers primary and second homes only, at 80% maximum.
Assets-only. No DTI is calculated when U.S. liquid assets equal the loan amount plus closing costs plus sixty months of any net loss on other residential property.
Not every dollar counts. Retirement accounts count at 70%, or 80% at age 59.5 and above. Business funds, gifts, most trusts (a revocable living trust is the exception), unvested stock, and cryptocurrency never count. An AUM statement showing managed brokerage assets may qualify as liquid assets, subject to underwriting.
Here is the catch for this article’s title. The two asset paths do not cover investment property. If the $3.5 million property is a rental, the realistic non-QM routes are bank statements or property-level rental coverage. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. The complete DSCR loans guide walks through how that route works.
What Changes at $3.5 Million
At this size, leverage and overlays tighten. The ladder below shows ceilings through select wholesale programs, subject to full underwriting.
| Use at roughly $3M to $4M | Purchase LTV ceiling | Credit tier shown |
|---|---|---|
| Primary residence | 75% | 720+ |
| Second home | 65% | 760+ |
| Investment property | 60% | 680+, with 700 overlay |
Super-jumbo overlays begin above $3,500,000 on a primary residence and above $3,000,000 on a second home or investment property. They include a 700 credit floor, a 0x30x24 housing history, and 48-month seasoning after any credit event. Borrowers must be U.S. citizens or permanent residents. Non-occupant co-borrowers are not allowed, rural property is out, and acreage tops out at ten acres. Cash-out proceeds cannot satisfy reserves.
Reserves run 9 months on loans above $1,500,000, plus 2 months per additional financed property up to a 12-month maximum. First-time investors typically need 12 months.
Above $4,000,000 the ladder changes and every file is reviewed case by case before submission. Any leverage figure at that size is a review outcome, not a promise.
The adjustable choice is not exclusive to private banks either. A bank portfolio program in the network carries twelve-month-statement files with 5- and 7-year fixed-period adjustables, interest-only to 60% LTV. Its 10-year fixed-period adjustable is fully amortizing. So the structural question and the lender-type question are separate. Lendmire’s piece How a Bank Statement Loan Weighs ARM vs Fixed for a Loan-Out Borrower covers that split in more depth. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
When a Private Bank ARM Is the Better Fit
A private bank ARM is the better fit when the relationship is the point. Consider a borrower with a large managed portfolio, a planned sale or refinance inside the initial period, and no wish to move custody. The bank can see the whole balance sheet, so documentation may feel lighter than a deposit-by-deposit review.
It also suits a borrower who values single-point servicing and is comfortable with the bank’s credit policy on title and property type. Some banks lend to entities and some do not, and it varies by bank. Confirm entity vesting before choosing, because that one answer can end the comparison.
The structure carries two risks that deserve plain statements.
First, the reset. The CFPB explains that an ARM’s new payment rate is the index plus the margin once the initial period ends, subject to any caps. It also notes that the margin is set in the loan agreement and does not change after closing. Later adjustments follow the market, not the borrower’s personal finances. A strong portfolio does not soften a reset.
Second, collateral. When a loan is pledged against securities, a brokerage’s educational page on borrowing against assets explains that falling collateral values can trigger a demand for more cash or securities, or repayment. That page covers securities-based lines, not mortgages, but the mechanism is the same. A pledge ties the loan to market swings. The reset and the margin call can arrive in the same bad quarter.
An ARM works best when the borrower has a liquidity cushion outside the pledged assets and a clear exit before the first reset.
When a Non-QM Fixed Loan Is the Better Fit
A non-QM fixed loan is the better fit for a long hold where payment certainty is worth more than flexibility. Picture an attorney who owns a rental outright for a decade. A stable obligation lets the coverage math stay the same on day one and year seven.
It also fits when custody should stay where it is. Nothing here requires moving assets, though statements and seasoning must be documented.
Entity vesting is a second advantage. Through select programs, a loan can often be titled in an LLC at closing, subject to program terms. Expect a personal guaranty and expect it to count in the borrower’s global DTI. An LLC does not remove personal exposure.
For a primary or second home, the asset paths above help when taxable income undersells the borrower. The program can run on liquid assets alone, with no DTI, if the liquidity test is met.
The costs of the fixed structure are real. The fixed choice gives up the chance to benefit if the market moves in the borrower’s favor. It usually carries a tighter document load than a bank that already knows you. At $3.5 million, leverage is also lower on an investment purchase than the same borrower might expect on a smaller loan. Fixed-versus-adjustable is a bet on hold period and risk tolerance, not a sourced rule. Hold-period fit is general reasoning, so test it against your own plan.
The network’s portfolio non-QM program also offers a 40-year term with a 10-year interest-only period on eligible files. Interest-only leverage never exceeds the ladder for the property and loan size.
Where the Files Break
Operators see the same friction on these files.
- Occupancy gets muddy. If the borrower plans to stay in the property, the file is a consumer-purpose loan, and the underwriting changes. Decide the use before choosing a path.
- Assets count twice. If a bank ARM pledges the same securities that a non-QM file needs as liquidity, the borrower cannot count them in both places.
- Statements are not consecutive. Transaction histories never substitute for consecutive statements.
- Entity papers are missing. Articles, operating agreement, good-standing certificate, EIN, and signing authority should be in hand before submission.
- Cash-out reserves. Cash-out proceeds cannot satisfy reserves on super-jumbo overlays, so reserves must be sourced elsewhere.
- Case-by-case surprises above $4,000,000. Do not plan around a leverage figure at that size until review is done.
Business-purpose context is worth a single paragraph here. DSCR and similar investor loans are designed for non-owner-occupied investment properties. Because they are business-purpose loans, they are reviewed differently from a standard owner-occupied mortgage. The Federal Register notice for the ability-to-repay rule states that business-purpose loans fall outside that rule, and investment-purpose loans are treated as business-purpose. Cash-out used for consumer purposes can change that, so keep the use of proceeds clean.
Tax treatment varies; consult a qualified professional.

Asset allowance: A method that divides eligible liquid assets by a set number of months to create qualifying income.
Reset: The date an adjustable loan’s payment starts to follow its index and margin.
Collateral call: A lender’s demand for more cash or securities when pledged assets fall in value.
Guarantor: The person who personally backs a loan taken in an entity’s name.
Fixed-period adjustable: A loan with an initial fixed stretch (such as five or seven years) that then adjusts.
A Balanced Verdict
If the borrower holds a large managed portfolio, plans a short hold, can vest the way the bank allows, and has liquidity outside the pledge, a private bank ARM deserves a real look. If the plan is a long hold, entity vesting matters, or custody should stay put, a non-QM fixed loan is the steadier structure.
For an investment property at this size, the asset paths are off the table in the network’s guidelines. The decision then comes down to bank statements or property cash flow, plus how much reset exposure the borrower will tolerate.
Run both against the same hold period before deciding. The cheaper-looking structure on day one can be the more expensive one at the first reset.

Frequently Asked Questions
Can an AUM-based borrower use asset-based qualification on a rental property?
Not through the asset paths in Lendmire’s network, which cover primary and second homes only. A rental purchase typically runs on bank statements or on property-level rental income, subject to lender guidelines. Confirm the property’s use first.
Do I have to sell my portfolio to qualify on assets?
No. Assets are counted as evidence of repayment ability, not liquidated. Retirement accounts count at 70%, or 80% at age 59.5 and above, and business funds, gifts, and cryptocurrency do not count.
What leverage is typical at this size?
Through select wholesale programs, subject to full underwriting, the ladder around $3,000,000 to $4,000,000 shows 75% on a primary residence purchase, 65% on a second home purchase, and 60% on an investment property purchase. Above $4,000,000 each file is reviewed case by case before submission.
Does an adjustable loan always cost less over time?
No. Payment changes after the initial period follow the index plus the margin, so the outcome depends on the market and the hold period. A short hold with a clear exit favors an adjustable. A long hold favors the fixed structure.
Can I close in an LLC?
Often yes, subject to program terms, and a personal guaranty is typical. Private banks vary on entity lending, so confirm before choosing.
