The Quick Read: A private bank mortgage is a loan from a bank that serves wealthy clients and keeps the loan on its own books, while a non-QM super jumbo is a very large loan documented outside standard mortgage rules; the two terms describe different things, so one loan can be both. The real difference is how the lender decides you can repay.
- A private bank usually underwrites your whole balance sheet and the relationship you bring.
- A non-QM super jumbo qualifies you through a documentation lane: bank statements, assets, or property cash flow.
- “Super jumbo” has no official dollar line. Each lender sets its own.
- Private bank terms often tie to deposits or assets held there. Non-QM programs generally do not.
- Above $4,000,000, Lendmire’s network reviews every file case by case before submission.
The honest answer is about fit. A private bank suits a borrower who already has, or wants, a deep banking relationship and whose wealth shows up clearly on a balance sheet. A non-QM super jumbo suits a borrower whose traditional personal-income documentation understates real income, who wants to keep assets where they are, or who owns property through an entity. Neither is cheaper or easier by default.

The right column shows guidelines from select wholesale programs, subject to full underwriting. The left column shows published industry norms, which vary by institution.
| Factor | Private bank mortgage | Non-QM super jumbo |
|---|---|---|
| Review basis | Whole balance sheet and relationship | Deposits, assets, or property rent |
| Documentation | Source of wealth, asset and liability statements | 12 or 24 months of statements, P&L, or assets |
| Property and vesting | Often case by case; usually the individual | Primary, second home, investment; entities vary |
| Relationship strings | Deposits or managed assets may apply | None needed to qualify |
| Credit and reserves | Set by the bank, judged on total liquidity | 660+ floor, DTI to 50%, 3/6/9 months reserves |
| Process shape | Credit-paper review, relationship-led | Guideline-driven, each file underwritten individually |
Key Terms Defined
Private bank mortgage: a home loan from a bank serving high-net-worth clients, usually held on the bank’s own balance sheet rather than sold.
Non-QM: a loan that falls outside Qualified Mortgage rules. It can be documented with statements, assets, or rental income instead of traditional personal-income documentation.
Super jumbo: a loan well above the conforming limit. No regulator defines the threshold, and each lender draws its own line.
Portfolio loan: a loan the lender keeps instead of selling. Private banks do this routinely, and some wholesale programs do too.
What a Private Bank Actually Is
Masterworks describes the dividing line as the balance sheet. A private bank takes deposits and lends directly, and it bundles banking, lending, and investment management. Its signature credit product is a securities-backed line, where your portfolio is pledged as collateral. The same source says entry points range from about $1 million to $10 million in investable assets, depending on the institution.
A mortgage from this kind of bank is typically underwritten as a package. The bank looks at your assets, liabilities, income streams, and what the relationship is worth to it. Published descriptions often mention flexibility on structure, such as interest-only terms or complex ownership. They also mention that pricing or approval may lean on deposits or assets you place there.
That model rewards people who fit it. It is not a standard scorecard, so results vary a lot from one bank to the next.
When the Private Bank Is the Better Fit
A private bank tends to win in a few situations.
You already hold substantial assets at the institution. Moving nothing is easy. The bank can see your wealth directly, which can make the credit story simple.
Your income is hard to document but your balance sheet is strong. Think concentrated stock, a recent liquidity event, or irregular compensation that deposits alone would not capture.
You want a bespoke structure. Unusual ownership, a custom repayment plan, or a single banker coordinating lending and investments can matter more than a standardized lane.
You value one relationship over several. If you plan to bank, borrow, and invest in one place, the ties may feel like a feature rather than a cost.
The trade-offs are real. A bank may want assets under management as a condition, and that puts part of your portfolio under the lender’s roof for the life of the loan. Terms can be flexible, but flexible does not mean cheaper. A private bank may also underwrite you personally instead of an LLC, which matters if you hold rentals in entities.
When the Non-QM Super Jumbo Is the Better Fit
A non-QM super jumbo tends to win when your traditional personal-income documentation does not tell the real story, or when you want financing that does not depend on where your assets sit.
You own a business. Lendmire’s wholesale network qualifies bank-statement files on 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 that depends on the type and size of the business, with service businesses that have no employees carrying the lowest ratio and product businesses or larger staffs carrying the highest. An accountant-provided ratio or a profit-and-loss method capped at 80% can also apply. Transfers from your own business into your personal account count in full.
You are asset-rich and income-light. An asset allowance divides liquid assets by 36, 60, or 84 months to build qualifying income, on primary and second homes only. An assets-only path needs liquidity equal to the loan plus closing costs and no debt-to-income calculation. Retirement accounts count at 70%, or 80% at age 59.5 and older. Business funds, gifts, unvested stock, and cryptocurrency do not count.
You are buying rentals. One investor lane qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. That keeps each rental from competing with your personal debts.
You do not want to move assets. Non-QM programs generally verify reserves and liquidity without requiring a banking relationship. Investment-property loans can be vested in an LLC, subject to lender program eligibility.
Where Each Path Gets Tighter at Size
Size changes both routes. On the network side, leverage on a primary residence steps down as the loan grows, through select wholesale programs, subject to full underwriting. On a purchase, the ceilings run 90% to $1,000,000, 85% to $2,000,000, 80% to $3,000,000, and 75% to $4,000,000 at the top credit tier. Second homes and investment property run about five points lower at every size.
Two wholesale programs cover the range. A portfolio non-QM bank-statement program carries files from $300,000 to $6,000,000. A bank portfolio jumbo program carries twelve-month-statement files up to $30,000,000 on its own ladder. On a primary-residence purchase, that ladder runs 65% to $5,000,000, 60% to $10,000,000, and 55% to $30,000,000, always on case-by-case review above $4,000,000.
Credit tightens too. The portfolio program starts at a 660 floor, the bank program at 680, and both move to 700 above the super-jumbo line. Reserves run 3 months to $500,000, 6 months to $1,500,000, and 9 months above that. Debt-to-income can reach 50%.
Cash-out has its own limit. On the portfolio program, cash-in-hand above 60% LTV is capped at $1,500,000. Lendmire’s piece Private Bank vs Non-QM Super Jumbo on Purchase vs Cash-Out walks through that split. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
A private bank has no published ladder to compare. Its limits are set by the institution, and the largest loans are usually judged one at a time.
The Cost of the Relationship
Private bank lending often comes bundled with something else. That might be deposits, managed assets, or a broader account structure. If you were going to move that money anyway, the bundle can work in your favor. If you were not, the real cost of the loan includes what you give up elsewhere.
Non-QM super jumbo lending keeps the transaction separate. You document income or assets, meet the reserve tier, and keep your portfolio where it is. The trade-off is that you work within a fixed guideline set, and exceptions are narrower than a bank’s discretion.
Think of it as discretion versus predictability. One bends to your story. The other asks your story to fit a lane.
Hybrid Moves Worth Considering
You do not have to choose forever. Some borrowers keep their wealth at a private bank and finance a specific property through a non-QM lane, so investments stay put while the loan stays separate. Others start with a non-QM loan when income documentation is the obstacle, then refinance later once the profile changes. Either way, check the exit terms before you sign.
How Investor Loans Are Treated Differently
Loans for rental property are usually business-purpose. Compliance Alliance explains that coverage turns on the purpose of the loan, not the property type, and credit to buy non-owner-occupied rental property is deemed business purpose. That is part of why investor lanes exist at all. Non-QM is still underwritten, though. The CFPB’s compliance guide says the rule requires a good-faith determination of repayment ability and does not ban particular loan features.
Tax treatment can depend on how the funds are used and how the property is held; investors should keep clear records and speak with a qualified tax professional before relying on any deduction.
Balanced Verdict
Choose the private bank when your wealth is easiest to see on a balance sheet, you are comfortable with a relationship that may include assets under management, and you want a bespoke structure. Choose the non-QM super jumbo when your income lives in business deposits, your assets are liquid but you would rather keep them where they are, or you are financing investment property through an entity.
A few questions sort most borrowers:
- Does your tax return understate what your business deposits show?
- Would you move assets to get the loan, and are you comfortable with that?
- Is the property a primary home, a second home, or an investment?
- Does the loan size exceed $4,000,000, where review is case by case on either path?
Neither route is the safer choice by default. The better one is the one whose documentation matches how you actually earn and hold money.

Frequently Asked Questions
Can a loan be both a private bank mortgage and a non-QM super jumbo?
Yes. A private bank can hold a jumbo loan on its own books and document it outside Qualified Mortgage rules. The terms come from different frameworks, one naming the lender and the other naming the documentation.
Does non-QM mean the lender skips underwriting?
No. The lender still reviews your ability to repay, and each file is underwritten individually. Non-QM changes the evidence, such as deposits, assets, or rent, not whether the review happens.
What if a private bank says no?
A decline from one bank often reflects that bank’s relationship requirements or appetite, not your overall creditworthiness. A non-QM lane may fit if your income documentation or asset location is the sticking point, subject to lender guidelines and full underwriting.
Do I have to move assets to get a non-QM super jumbo?
Generally not. Programs verify liquidity and reserves, but they do not typically condition approval on a banking relationship. Reserves are 3, 6, or 9 months by loan size, and cash-out proceeds cannot satisfy reserves above the super-jumbo line.
