Finance New Construction With A Super Jumbo Bank — The Quick Read: A super jumbo bank statement loan lets high-income, self-employed buyers finance a newly built home using deposit history instead of traditional personal-income documentation. It only works once the home is finished and has a certificate of occupancy — it is not construction funding. Loan sizes run from $300,000 to $30,000,000 through select lenders in Lendmire’s wholesale network, with leverage stepping down as the loan gets bigger. Above $4,000,000, every file gets reviewed case by case before it goes to a lender.
Key Takeaways
- This loan pays off the builder or refinances a finished, occupancy-certified home. It does not fund the actual build.
- Income is calculated from 12 or 24 months of bank deposits, minus a standard expense ratio — not from traditional personal-income documentation.
- Leverage steps down as loan size grows. A $900,000 primary residence purchase and a $4,500,000 purchase are underwritten on completely different grids.
- Above $3,500,000 on a primary home (or $3,000,000 on a second home or rental), overlays tighten: higher credit floor, longer seasoning on credit events, and cash-out proceeds can’t be counted toward reserves.
- A newly built, unleased home is appraised using a rent schedule, not an actual lease — that appraisal does double duty on value and rent.
What Counts as “Super Jumbo,” and Why Does New Construction Change the Rules?
There’s no federal definition of “super jumbo.” The only government number in this conversation is the annual conforming loan limit set by the Federal Housing Finance Agency. Anything above that limit is simply “jumbo” by definition. “Super jumbo” is a lender-invented tier, not a regulated one. Different lenders draw that line in different places.
New construction adds a second layer that trips up a lot of buyers. Bank statement financing — like most non-agency mortgage products — is take-out financing. It buys or refinances a home after it’s built, not during. The property needs to be 100% complete with a certificate of occupancy before a lender will touch it with permanent financing. If you’re trying to fund the actual build — the lot, the draws, the framing-to-finish process — that’s a construction loan, a separate product entirely, and this article isn’t about that. This one is about what happens once the builder hands you the keys and you need a large, income-flexible mortgage to close.
Key Terms Defined
Bank statement loan — A mortgage that qualifies a borrower’s income from bank deposits instead of traditional personal-income documentation, common for self-employed buyers whose returns understate real cash flow.
Super jumbo — A loan amount well above the standard jumbo threshold, generally discussed as several million dollars and up; the exact starting line varies by lender since no agency defines it.
Expense ratio — The percentage of gross business deposits treated as business costs before the rest counts as qualifying income. A lower certified ratio means more income counts.
Certificate of occupancy — The local government sign-off that a newly built home is legally safe to live in. It clears one hurdle, not the whole loan file.
Take-out financing — The permanent loan that pays off a construction loan or purchases a finished home from a builder, replacing short-term construction funding.
What Has to Be True Before You Apply?
The property has to be finished, safe, and documented. That’s the gate before lenders even discuss income or leverage. Lenders in this space generally want the certificate of occupancy or final inspection. They also want evidence that utilities are active. If there’s already a tenant or builder lease in place, they want a signed lease with the lessor’s W-9. Ground-up construction, incomplete structures, and homes without a certificate of occupancy generally aren’t eligible for this kind of permanent financing at all.
When the home is new and has no sales or rental history, the appraisal carries more weight than usual. For a single unit, appraisers typically use the Fannie Mae Single-Family Comparable Rent Schedule (Form 1007) alongside the standard appraisal report; two- to four-unit properties use the equivalent income property form. Fannie Mae’s own documentation describes Form 1007 as the tool lenders use to pull market rent from an appraiser when there’s no lease yet to point to. That form isn’t exclusive to agency loans — it’s the industry reference point non-agency lenders lean on too, because it’s the only standardized way to estimate rent on a home nobody has ever lived in.
That appraisal is doing two separate jobs. It sets the value that leverage gets applied against, and — if rent matters to the file — it sets the income figure too. A soft appraisal can shrink both the loan amount and the rent number in the same report, and investors sizing a super jumbo purchase should model both outcomes before they get attached to a number.
How Does Income Get Calculated From Bank Statements?
Qualifying income comes from deposits divided by the number of statement months, after an expense ratio is applied — not from a tax return. Across Lendmire’s wholesale network, the standard approach uses 12 or 24 consecutive months of bank statements, and the ratio applied to business deposits depends on the type of business.
Fixed ratios generally scale with business size and type. Businesses with no employees typically see one ratio. Those with a handful of employees see a higher one. Larger or product-based businesses see a higher one still. A borrower can also bring an accountant-provided ratio instead. Or they can use a profit-and-loss method capped at 80%, if either option produces a stronger number than the default. Personal-account deposits are treated differently. Money transferred from a borrower’s own business into a personal account counts at 100%, with no haircut.
That ratio matters more than most borrowers expect. A service-based sole proprietor and a retail business owner with identical gross deposits can qualify for very different loan amounts once their expense ratios are applied — which is exactly why a CPA-certified ratio is worth chasing before locking in a purchase contract on an expensive new build.
Business deposits generally only count toward one borrower’s income if that borrower holds at least 25% ownership in the business. Statements also need to be continuous — a printed transaction history isn’t a substitute for actual bank statements in most underwriting files.
For borrowers who don’t want income tied to deposits at all, asset-based paths exist. An asset allowance divides liquid assets by 36, 60, or 84 months to produce a supplemental or standalone income figure, while an assets-only path requires liquidity equal to the loan amount plus closing costs, with no debt-to-income calculation at all. Both are worth exploring for a borrower whose deposit history is thin but whose balance sheet isn’t.
How Big Can This Loan Get, and What Leverage Applies?
Loan sizes on this strategy run from $300,000 to $30,000,000, and they get there through two different programs stacked on top of each other. A portfolio bank-statement program carries files to $6,000,000. A separate bank portfolio program, using a 12-month statement, carries loans beyond that on its own ladder — 65% at the lower end, stepping down to 60% and eventually 55% as the loan approaches $30,000,000, with interest-only capped at 60% or the band’s ceiling, whichever is lower.
Leverage on a primary residence steps down steadily as size increases: up to 90% around $1,000,000, tightening to roughly 75% near $4,000,000 at the strongest credit tier, then moving to case-by-case review as the loan approaches $6,000,000 and beyond. Second homes and investment properties run about five points lower than a primary residence at every size band. None of these are flat “up to” numbers that apply the same way at every loan amount — the leverage available on a $900,000 purchase and a $4,200,000 purchase come off entirely different parts of the grid.
Above $3,500,000 on a primary residence, or $3,000,000 on a second home or rental, overlays tighten further. Lenders typically want a 700 credit floor, a clean 24-month payment history, and 48 months of seasoning on any past credit event. Cash-out proceeds can’t be used to satisfy reserve requirements. Above $4,000,000 generally, every file leaves the standardized grid behind. It goes to individual underwriter review before it’s even submitted to a lender. That’s not a formality — it’s the actual process at that size.
Reserves scale with loan size too: typically three months of payments up to $500,000, six months up to $1,500,000, and nine months above that, plus two additional months for every other financed property up to a 12-month cap. First-time investors are often held to a 12-month reserve requirement regardless of loan size.
Where This Strategy Breaks — Tradeoffs and Failure Points
The single most expensive mistake is sequencing: assuming this loan funds the build itself. It doesn’t. If a builder is expecting the buyer’s capital during construction, and the buyer is counting on this financing to show up at that stage, the deal falls apart. This product closes after completion, as a purchase or refinance — full stop.
A second failure point shows up on refinances, not purchases. A vacant new-build is generally fine to finance on a purchase, using the appraiser’s market rent from the 1007 or 1025 form. On a refinance, most programs want the property leased or occupied first — a vacant refinance on a spec home an investor has been sitting on is a much harder file to place.
Commingled bank accounts cause real friction too. Business and personal deposits treated so differently under the expense-ratio math mean a single mixed account often can’t be cleanly parsed, and some lenders in the network won’t work with a commingled file at all. Separating accounts before the application, not during underwriting, saves real time.
An expense ratio running above the standard bands is another snag — a high-overhead business can end up qualifying for meaningfully less loan than gross revenue would suggest, which is worth modeling before shopping for a house, not after.
And for anyone planning a short-term rental on the new build, the standard rent schedule form has real limits. It isn’t built for short-term rental income and doesn’t account for nightly-rate variability or the operating costs unique to that model — appraisers sometimes need a different data source entirely, and lenders will scrutinize that income differently than a standard long-term lease.
DSCR loans are a related but distinct non-agency product. Lenders review them based on a property’s rental income, not the borrower’s deposits. Lendmire covers these in its complete DSCR loans guide. They’re worth a look if you’re an investor whose new-build purchase is purely a rental play, rather than a primary or second home.
Who Fits This Strategy — and Who Doesn’t
This works best for a high-earning, self-employed buyer — a founder, physician, attorney, or business owner. These buyers often have traditional income documentation that understates their real cash flow. They may be buying or refinancing a finished, occupancy-certified new build above standard jumbo size. It also fits an investor whose personal income looks irregular during a build cycle. For these investors, deposits or liquid assets tell a stronger story than a tax return does.
It doesn’t fit a buyer looking to fund the construction phase itself — that’s a different loan entirely. It’s also a rough fit for anyone with heavily commingled accounts, an expense-heavy business with no CPA letter to lower the ratio, or a plan to finance a short-term rental new-build without a clear appraisal strategy in place. And for a loan above roughly $4,000,000, anyone expecting a published rate sheet is going to be disappointed — that tier runs on individual underwriter judgment, not a fixed grid.

DSCR and bank statement loans are different from a standard owner-occupied mortgage. They’re business-purpose or alternative-documentation products, and lenders review them differently. Every leverage, credit, and reserve figure above is just a typical range from select wholesale-network guidelines. These figures are subject to full underwriting — they’re not a promise to lend. Tax treatment can depend on how you use the funds and how you hold the property. Investors should keep clear records. Talk to a qualified tax professional before you rely on any deduction.

Frequently Asked Questions
Can a super jumbo bank statement loan fund the actual construction of a new home?
No. This is take-out financing for a home that’s already complete and holds a certificate of occupancy. Funding the build itself requires a separate construction loan, and the two products aren’t interchangeable.
How is income calculated without conventional personal-income paperwork?
Income is based on 12 or 24 months of bank deposits, with an expense ratio applied to business deposits before the remainder counts. Personal transfers from a borrower’s own business generally count in full, and a CPA-certified ratio can raise the coverage figure above the standard default.
What happens if the new-build home is still vacant when I apply?
On a purchase, that’s generally fine — the appraiser provides a market rent estimate using a standardized rent schedule form since there’s no lease yet. On a refinance, most programs want the home leased or occupied first, which makes a vacant refinance on a spec home harder to place.
Is there a hard dollar line where “jumbo” becomes “super jumbo”?
No federal definition exists for either term beyond the conforming loan limit, which marks the start of jumbo. Super jumbo is a lender-defined tier that varies from one program to the next, which is why leverage and documentation differ across lenders at the same loan size.
What changes once a loan gets above $4,000,000?
Underwriting leaves the standardized grid and moves to case-by-case review before the file is even submitted. Credit, seasoning, and reserve requirements also tighten, and cash-out proceeds can’t be used to satisfy reserve requirements above the super jumbo overlay threshold. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
