The Private Client Guide to Jumbo Loans (2026): How to Qualify on Income a Tax Return Does Not Describe

What is a jumbo loan in 2026?

A jumbo loan is a mortgage whose loan amount exceeds the conforming loan limit set each year by the Federal Housing Finance Agency, which means Fannie Mae and Freddie Mac cannot buy it. For 2026 the baseline limit for a one-unit home is $832,750, and the ceiling in designated high-cost areas is $1,249,125.

The limit matters because it divides two different credit systems. Below it, a loan is typically underwritten to the agencies' published rules and sold. Above it, the lender either holds the loan or sells it under its own guideline, and that lender decides how income, assets and property are read. That freedom is the whole reason a jumbo can qualify a borrower whose tax return understates what the household earns.

This guide covers jumbo financing from $1,000,000 upward, the range served by Mbanc Private Client Lending, the $1,000,000-minimum desk of Mortgage Bank of California Inc. dba Mbanc. Every Private Client loan sits above the baseline limit, and most sit above the high-cost ceiling as well.

Why does tax-return underwriting understate high earners?

Tax-return underwriting reads income after every legitimate deduction, so the better your accountant does, the smaller your mortgage becomes. A business owner whose company deposits several million dollars a year can show modest adjusted gross income once depreciation, retained earnings, vehicle and travel costs, retirement contributions and entity structure are applied. The return is accurate. It was simply built to measure taxable income, not the cash flow that services a mortgage.

Three kinds of institution see the same client differently. Preferred retail banking treats the client as valuable but underwrites the mortgage on tax returns, exactly as it would for a salaried borrower, so the CPA's lawful minimization is counted against the file. The wealth-management private bank will read the balance sheet, but usually as an accommodation to a substantial asset relationship moved into its custody. Private client lending reads the profile as it actually earns and holds wealth, and asks for nothing to move. We have defined the category in what private client lending is.

The pattern shows in our own book. Of the 440 loans of $1,000,000 or more that Mbanc funded from February 2021 to 7 July 2026, 83% went to self-employed borrowers, and 92% were documented without a tax return at all. Those borrowers were not marginal. They were people whose income a tax return was never designed to describe.

What is a non-QM jumbo loan, and is it still fully underwritten?

A non-QM jumbo is a jumbo mortgage that falls outside the federal Qualified Mortgage definition, usually because of how income is documented or because it carries a feature such as an interest-only period. It is still fully underwritten: every mortgage on a home you live in, QM or not, must satisfy the Ability-to-Repay rule in Regulation Z, 12 CFR 1026.43.

The Consumer Financial Protection Bureau describes a Qualified Mortgage as one without risky features such as interest-only periods, negative amortization, or terms longer than the regulation's maximum. An interest-only loan is therefore non-QM by definition, however strong the borrower. Ability-to-Repay still requires the lender to make a reasonable, good-faith determination, verified with third-party records, of income or assets, the payment, other debts, and credit history.

Plainly stated, this is long-term, fully underwritten residential mortgage financing from a licensed mortgage bank. It is not short-term hard money or bridge capital, and it is not a loan made on the property's value alone.

Which jumbo loan program fits how you are paid?

The right program is the one whose documents describe your income most completely: deposits for business owners, 1099s for independent earners, account balances for the asset rich, and rent for investors. Each of the four is a full jumbo program with its own formula, and a borrower can sometimes qualify on more than one. When two fit, the desk shows both and lets the numbers decide.

Each program has its own guide: qualifying with bank statements, qualifying with 1099 income, qualifying on assets instead of income, and qualifying an investment property on its rent. The program pages set out current terms: bank statement jumbo loans, 1099 jumbo loans, asset-based jumbo loans and DSCR jumbo loans.

How is qualifying income calculated on each program?

Qualifying income is calculated from the documents themselves, with a fixed formula per program, and then tested against a maximum debt-to-income ratio of 50% (55% on a primary residence with $3,500 of monthly residual income, 6 months of reserves, a qualifying LTV and bank statement income) and a minimum monthly residual income of $1,500 on the three alternative-documentation programs. The investor program skips personal income entirely.

Bank statements (Founder Loan)

The underwriter totals 12 or 24 consecutive months of deposits and divides by the number of months. On personal statements, qualifying deposits count in full; transfers between your own accounts are excluded, and one-off items are explained or excluded. On business statements, deposits are first multiplied by your ownership percentage (you must own at least 25% of the business; a sole proprietor or single-member entity counts as 100%), then reduced by an expense factor: the standard factor is 50%, or a lower ratio verified in writing by a CPA, EA or tax preparer, with a floor of 10%, or the net income from a third-party-prepared profit and loss statement that the statements support. The program does not look at the net profit line on a return.

1099 receipts (Operator Loan)

Qualifying income is 90% of gross 1099 receipts, the standard 10% expense factor, rather than net income after Schedule C deductions; some programs allow a lower factor when a CPA, EA or tax preparer verifies it in writing. One or two years can be used. On some programs, 1099s issued to your 100%-owned LLC are acceptable with a third-party letter showing expenses of 10% or less, a business narrative and proof of ownership. Year-to-date deposits or stubs are requested when the last 1099 is more than 120 days old.

Assets (AR Loan)

Eligible assets are valued per the investor guideline for your file: 100% of checking, savings, money market, CDs and short Treasuries, 70% to 80% of publicly traded stocks, bonds and mutual funds, and retirement accounts at 60% to 80% depending on your age. Eligible assets after the set-aside must be at least the lower of $1,000,000 or 150% of the loan amount. Funds needed for the down payment, closing costs and required reserves are set aside first, then the remainder is divided by 84 to give monthly qualifying income. Nothing is sold or moved. Asset depletion and asset utilization are used interchangeably for this method.

Rent (IL Loan)

The property qualifies itself: DSCR = gross monthly rent / PITIA. Qualifying rent is the signed lease or the appraiser's market rent analysis; where both exist, the guideline uses the higher of the two, capped at 120% of the other, and a lease that runs higher needs 2 months of receipts. On a refinance a signed lease is required, or a lower LTV applies. There is no personal income, no tax return, no employment verification and no DTI.

How much can I borrow on a jumbo loan?

Across the four programs, loan amounts run from $1,000,000 to a standard maximum of $3,000,000, rising to $4,000,000 for a primary-residence purchase at a 720 score and to $3,500,000 for an investment purchase on the IL Loan at 700. Cash-out stops at $3,000,000. The ceiling is always stated as a loan amount, never a purchase price, because the same loan amount can sit under very different homes depending on the down payment.

The loan amount that income supports is a separate question from the ceiling. On the three alternative-documentation programs, total monthly debts including the new PITIA may not exceed 50% of qualifying income (55% on a primary residence under the conditions above), and at least $1,500 of monthly residual income must remain. Every document by program is listed in the jumbo loan documents checklist.

Pricing follows the same variables that set eligibility: credit score, LTV, documentation type, occupancy, loan amount, interest-only, and prepayment structure. The desk does not publish rates. Terms are given in writing, per file, after the facts are known.

What LTV and down payment does a jumbo loan require?

Maximum LTV, and with it the minimum down payment, is set by program, occupancy, credit and transaction type. Cash-out is typically tighter than purchase and stops at $3,000,000. Exact LTV is a file conversation.

Interest-only does not reduce LTV on the Founder, Operator or AR Loan.

On a cash-out refinance, cash in hand is capped at $1,000,000 on the alternative-documentation programs above an LTV threshold and is unlimited below it; on the IL Loan the caps are $500,000 and $1,000,000. Six months on title are needed to use the appraised value; under six months the lower of purchase price plus documented improvements or appraised value applies. Refinancing a free-and-clear property is cash-out, and a cash-out within 12 months of a prior cash-out is itself cash-out.

How many months of reserves does a jumbo loan require?

Reserves on the Founder, Operator and AR Loans are 3 or 6 months of PITIA depending on LTV, 9 months on any loan amount over $1,500,000 and 12 months over $2,500,000; on the IL Loan they are 2 months, 6 months over $1,500,000 and 12 months over $2,500,000, with 12 months for a first-time investor. On an interest-only loan, reserves are measured on the interest-only payment. Reserves must be liquid or eligible after closing. They stay in your own accounts, at your own institutions; nothing is deposited with Mbanc.

What credit score and credit history does a jumbo loan require?

The desk's credit floor is 680, with 700 required for the $3,500,000 investment ceiling on the IL Loan and 720 for the $4,000,000 primary-residence ceiling. Below 680, the file belongs to a different conversation, not this desk.

History matters as much as the score. A bankruptcy, foreclosure, short sale, deed-in-lieu or loan modification needs 36 months of seasoning, measured from the application date, for full terms; at 24 months a file can still proceed at a lower maximum LTV and a $1,500,000 loan amount. Mortgage payment history may show no more than one 30-day late in the last 12 months for full terms, and no 60-day late in 12 months on the same reduced LTV and $1,500,000 path. A recent housing late, an open foreclosure or an unseasoned bankruptcy usually ends the file, and the desk will say so on the first call rather than after a credit pull.

Credit is pulled only when you decide to proceed. The first conversation uses the score you report, and the answer you receive is conditional on the report confirming it.

Which properties and ownership structures qualify?

Single-family homes, 2 to 4 unit properties, warrantable and non-warrantable condominiums, condotels and completed properties of most kinds qualify; cooperative apartments and construction draws do not. Unique properties are reviewed case by case.

• Condos. Warrantable and non-warrantable condos are eligible. Condotels are eligible on the alternative-documentation programs to a $2,500,000 loan amount, and on the IL Loan to $1,500,000.
• 2 to 4 units and acreage. 2 to 4 units are eligible on every program (not on the IL Loan in Illinois or New York). Rural property is reviewed case by case, as unique properties are.
• Co-ops. Not financed anywhere at Mbanc. In New York City, condos yes, co-ops no.
• Construction. Completed properties only. A finished new build qualifies; a draw schedule does not.
• Appraisals. Loan amounts up to $2,000,000 need one full appraisal plus a desk review (CDA). Above $2,000,000, two full appraisals from different companies are required, and the lower value governs.
• Vesting. An LLC, partnership or corporation may hold title on investment property on every program, never on a primary residence or second home. The entity must be formed to own, finance or manage real estate, be U.S.-domiciled, and have at most four members and two layers; members holding at least 25% cumulative ownership apply, their credit is used, and every applying member signs a personal guaranty or the Note. Revocable trusts may hold title on any occupancy; irrevocable trusts, land trusts and IRAs may not.
• Texas homestead cash-out. A Section 50(a)(6) cash-out on a Texas primary residence is available on the Founder, Operator and AR Loans as a fully amortizing loan only (no interest-only), under the Texas constitutional rules (a combined loan limit, 12-day waiting period, 3-day rescission, one per 12 months, 2% fee cap).
• Portfolio size. There is no automatic cap at ten financed properties. A large portfolio is a risk discussion, not a disqualifier.

How the attorney's structure interacts with the loan is a question for the attorney, and how a purchase fits the wider plan is a question for the wealth manager. The division of labor is set out in the four-seat advisory table.

What loan structures are available, including interest-only?

The structures available on every program are fully amortizing loans and an initial interest-only period on a long-term structure; the exact structure for your file is set out in writing with your terms. Interest-only was the structure chosen on 68% of the jumbo loans in Mbanc's funded record (299 of 440).

On an interest-only loan, the payment for an initial period covers interest only. Principal reduction during that period is elective, not scheduled. How your loan treats extra principal is set out in your loan documents. When the period ends, the loan begins to amortize over the remaining term and the payment rises, often sharply. That is the main risk, and it should be planned for from the day the loan closes, not discovered when the period ends. On the three alternative-documentation programs, the borrower is qualified on the fully amortizing payment, not the interest-only payment, so the file has already shown it can carry the higher number. On the DSCR program, the ratio uses the interest-only payment (ITIA). Reserves on an interest-only loan are measured on the interest-only payment. Interest-only is available to foreign nationals on the IL Loan and is not available on a Texas homestead cash-out.

The banker states in writing whether a prepayment penalty applies, before anything is signed. The full treatment of interest-only, including the tax deduction limit of $750,000 of acquisition debt, is in the interest-only jumbo loan guide; the program summary is on the interest-only jumbo loans page. Your CPA, not your lender, decides how the deduction applies to you.

Where does Mbanc Private Client Lending lend, and for which occupancy?

Primary residences, second homes and investment property are financed in 22 states, and investment property alone in another 24 states plus the District of Columbia, for investment coverage in 46 states plus D.C. Four states are not served.

• All occupancies (22 states): Arizona, California, Colorado, Connecticut, Florida, Georgia, Idaho, Illinois, Maryland, Michigan, Nevada, New Jersey, North Carolina, Ohio, Oregon, Pennsylvania, South Carolina, Tennessee, Texas, Utah, Virginia, Washington.
• Investment property only (24 states plus D.C.): Alabama, Alaska, Arkansas, Delaware, District of Columbia, Hawaii, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maine, Massachusetts, Mississippi, Montana, Nebraska, New Hampshire, New Mexico, New York, Oklahoma, Rhode Island, Vermont, West Virginia, Wisconsin, Wyoming.
• Not lending: Minnesota, Missouri, North Dakota, South Dakota.

The practical consequence: a residence in Manhattan, Boston or Honolulu is outside the desk, but a rental in any of those markets can be financed on any of the four programs, including on its own rent through the IL Loan. Only owner occupancy is excluded there. Licensing is listed on the licensing page.

What do 440 funded jumbo loans show?

They show that the borrower at $1,000,000 and above is overwhelmingly self-employed, documented without tax returns, and choosing interest-only. The record below is Mbanc's own, covering every loan of $1,000,000 or more funded from February 2021 to 7 July 2026.

The 97% pull-through is the number we would point to first. It reflects underwriting done in-house and up front: the desk says what a file needs before it is submitted, so very little fails late. A fuller reading of the data is in what 440 funded jumbo loans reveal.

What happens from the first call to closing?

Three steps: a 15-minute conversation with no application and no credit pull, a short document list for your program, and written terms before anything is signed. Mayer Dallal reads every inquiry and makes the call himself, and one banker owns the file through closing.

1. The conversation. Bring four facts: occupancy, state, loan amount, and how you are paid. No rate target is needed. You leave with a direct answer: what the file would take, or that it is not a fit.
2. What the file would take. Identity, the income documents for your program, evidence of funds to close, and the purchase contract if buying. Documents upload through the Aura portal. If you are buying, the property-level underwriting (appraisal, title, condo review) follows once the home is under contract.
3. Terms in writing. Rate, structure, interest-only period, payment before and after any reset, and prepayment terms, all in writing before you sign.

Recent complete files have closed in about 15 days, and earlier files in 18 to 21 days. That is typical experience, not a commitment; timing depends on appraisal, title and how complete the file is.

Who is this not for, and when is a conventional jumbo better?

If your income is salaried, your tax return describes it well, and you can document it with W-2s, a conventional or bank portfolio jumbo is often the better tool, and we will say so. Alternative documentation exists to read income a return misses; it is not a substitute for a clean full-documentation file that already qualifies.

• Loan amounts under $1,000,000. These belong on the core Mbanc desk at mbanc.com or (844) 918-1886.
• A W-2 file under the local high-cost limit. In a designated high-cost county, a loan amount up to $1,249,125 may be conforming. A salaried borrower who fits agency guidelines there should usually take the agency loan.
• Credit below 680. Outside this desk at every loan amount.
• Thin first-time W-2 files. A strong salaried first-time buyer is usually better served by agency or conventional jumbo guidelines.
• Pure rate shopping. The value here is in reading income correctly and structuring the loan; a borrower who needs only the lowest headline number on a conventional file should take the conventional file.
• Brand-new income without deposit history. Twelve months of self-employment can work and two years is cleaner, but income without a deposit trail is a poor fit.
• A clean conventional approval already in hand. The desk will not race it. Files in process elsewhere can be reviewed when the other lender is waiting on an investor and the income type fits.

The comparison is worked through in detail in non-QM jumbo versus conventional jumbo.
