Super Jumbo Bank Statement Loan Requirements For New Construction — The Quick Read: These files run on two separate tracks that meet only at closing: an income track built from 12 or 24 months of deposits instead of traditional personal-income documentation, and a collateral track that needs a certificate of occupancy plus completion documentation before the permanent loan can fund. Loan sizes through select lenders in Lendmire’s wholesale network run from $300,000 to $30,000,000 across two different programs, with leverage stepping down as the balance climbs. The catch on new construction specifically isn’t the income math — it’s proving the building is legally done.

Key Terms Defined
Super jumbo mortgage — a loan well above standard jumbo size, generally into seven figures, with no government agency setting the line; every lender draws its own cutoff.
Bank statement loan — a mortgage that qualifies income from deposit history on personal or business bank statements instead of traditional personal-income documentation or W-2s.
Expense ratio — a fixed percentage subtracted from business bank deposits to estimate overhead before the rest counts as income.
Certificate of occupancy (CO) — a document issued by the local building department confirming a structure passed inspection and is legally safe to occupy. The lender doesn’t issue it and doesn’t control the timeline.
Form 1004D — an appraisal update/completion report used to confirm that construction items noted as “subject to” in an earlier appraisal are actually finished.
Temporary certificate of occupancy (TCO) — a short-term occupancy clearance, often valid around 90 days, issued when a building is mostly but not fully finished.
Why New Construction Complicates a Bank Statement File
New construction adds a second underwriting track that a standard purchase or refinance never triggers. On a resale property, income qualification and collateral qualification move in parallel. They rarely collide. On new construction, they can’t fully resolve until the building is finished. And “finished” is a legal determination made by a local building department, not by the lender.
That means a bank statement file on new construction has two clocks running. The income clock starts when the lender pulls 12 or 24 months of statements. The construction clock runs on its own schedule, tied to permitting, inspections, and the builder’s pace — none of which the lender controls. If the construction clock runs long, the income clock may need to be refreshed before the loan can fund, because deposit history six months old doesn’t necessarily reflect current cash flow.
How the Income Side Actually Gets Calculated
Income on these files comes from deposits, not returns, run through an expense ratio before it counts as qualifying income.
The lender picks a lookback window first — 12 or 24 consecutive months of statements. A longer window smooths out the lumpy deposit patterns common in construction and contracting income, where draws land unevenly around project milestones. A shorter window usually means tighter compensating factors elsewhere in the file, like higher reserves or a stronger credit score.
For business accounts, an expense ratio gets applied before the deposits count. Through select lenders in the network, this generally runs on fixed bands that scale with headcount and whether the business sells a physical product, with lower ratios for lean service operations and higher ratios as staffing or inventory needs grow. Some files use an accountant-provided ratio instead, or a profit-and-loss method capped at 80%. Transfers from the borrower’s own business into a personal account count in full — no expense ratio applied there, since the ratio already got applied on the business side.
This matters more for construction-adjacent borrowers than almost any other income type. A general contractor, developer, or builder-investor’s personal deposit history is often thin, since most of the cash sits and moves inside the business account. Getting the expense ratio calculation right — and choosing the account and lookback window that actually reflect the business’s real overhead — is the single biggest lever on how much qualifying income the file shows.
Statements have to be actual consecutive bank statements. Transaction printouts or downloaded histories don’t substitute. And for a business account, ownership share matters: most programs in the network require at least 25% ownership before those deposits count toward the borrower’s personal income.
What Has to Happen on the Collateral Side Before the Loan Can Close
The property side of a new-construction file needs proof the building is done and legally occupiable — a certificate of occupancy plus either a Form 1004D completion report or an accepted alternative — before the permanent loan can fund.
The certificate of occupancy is issued by the local building department after its own inspections, confirming the finished structure matches approved plans and passed code. Lenders lean on it heavily, but they don’t issue it and can’t speed it up. Delays in a builder working through a municipal inspection queue are a permitting problem, not an underwriting problem — but they still hold up the closing either way.
Form 1004D exists to confirm that whatever an earlier appraisal listed as “subject to completion” is now actually finished. The appraiser can complete this through an on-site visual inspection. In some cases, a virtual inspection, digital photos, or site video will work instead. Either way, the documentation has to include a visually verifiable exhibit. Some files skip 1004D entirely. Instead, they use a builder or borrower attestation letter confirming the home was completed according to plans, specifications, and any change orders. This is a common alternative on new-construction files in the non-QM space. It’s borrowed from agency-world practice, even though non-QM lenders aren’t bound by agency rules.
A temporary certificate of occupancy is the most common friction point on these files. A TCO gets issued when a property is mostly finished with only minor items left, and it’s typically valid for a limited window — often around 90 days depending on the municipality. A file that closes relying on a TCO carries real timing risk if the permanent CO doesn’t get issued before the temporary one expires. Confirming the TCO’s expiration date against the expected closing date is a basic step that gets skipped more often than it should.
CO requirements aren’t uniform everywhere, either. Some states require a certificate of occupancy for essentially all new construction, changes of occupancy, and additions. Other states leave more of this to the local building authority. A bank statement program operating across multiple states has to defer to whatever the local jurisdiction requires. There’s no single national standard to fall back on.
Size and Leverage — What the Ladder Actually Looks Like
Through select lenders in Lendmire’s wholesale network, super jumbo bank statement financing runs from $300,000 to $30,000,000 across two distinct programs, and leverage steps down as the balance climbs rather than staying flat at one number.
A portfolio non-QM bank-statement program carries files to $6,000,000. A separate bank portfolio program, using 12-month statements, carries files on its own ladder to $30,000,000 — 65% loan-to-value to $5,000,000, 60% to $10,000,000, and 55% to $30,000,000, with interest-only capped at 60% or the band’s ceiling, whichever is lower.
On a primary residence, leverage typically runs like this through select wholesale-network guidelines, subject to full underwriting:
| Loan Size | Purchase LTV | Credit Floor |
|---|---|---|
| $300K-$1M | 90% | 680+ |
| $1M-$1.5M | 85% | 700+ |
| $2M-$2.5M | 80% | 720+ |
| $3M-$3.5M | 75% | 720+ |
| $4M-$5M | 65% (case-by-case) | 680+ |
| $10M-$20M | 55% (case-by-case) | 680+ |
Second homes and investment properties typically run about five points lower at every size band. Every figure above $4,000,000 is reviewed case by case before submission — that review isn’t optional, and it applies regardless of how strong the file otherwise looks. Above $3,500,000 on a primary residence (and $3,000,000 on a second home or investment property), a set of super-jumbo overlays kicks in: a 700 credit floor, a clean 24-month housing payment history, 48-month seasoning on any credit event, no non-occupant co-borrowers, no rural property, and a 10-acre maximum lot size. Cash-out proceeds can’t be used to satisfy reserve requirements on these files.
Reserves, Credit, and DTI at This Scale
Reserves scale with loan size rather than sitting at one flat number: typically 3 months of payments to $500,000, 6 months to $1,500,000, and 9 months above that, plus 2 additional months per other financed property up to a 12-month cap. First-time real estate investors typically need 12 months regardless of loan size.
Credit floors run at 660 on the portfolio program, 680 on the bank program, and 700 once a file crosses into super-jumbo overlay territory. Debt-to-income can run as high as 50% on most files. None of these are hard universal numbers — they’re typical ranges from select wholesale-network guidelines, and every file still goes through full underwriting.
Where the General Rule Breaks
A few scenarios routinely knock a new-construction bank statement file off the standard path.
Deposits decline during the build. If a borrower’s construction-adjacent business slows during the build itself — common when an owner-operator is personally managing the project instead of running other revenue-generating work — the qualifying income calculated at application may not hold by the time the CO gets issued months later. A refreshed statement pull near closing is common on files where the construction timeline runs long.
The postponed-improvements carve-out doesn’t automatically apply. In the agency world, postponed work is allowed if the remaining cost is under 10% of the home’s value, the work finishes within a defined completion window, and the escrow account is funded at 120% of the estimated cost, according to Homebuyer.com’s explainer of the Fannie Mae rule. Non-QM lenders aren’t bound by this exact structure, but most portfolio programs build a similar logic into their own overlays — full completion, or a tightly capped and escrowed exception, is the norm rather than an open-ended allowance.
Cash-out after a self-funded build doesn’t automatically reach full appraised value. An investor who paid cash to build and wants to pull equity out once the property is finished and rented is often capped by documented cost rather than the new appraised value — the gap between what was spent and what the home is now worth doesn’t automatically convert to cash-out proceeds. Program-specific seasoning rules govern how soon and how much can be recovered, and they vary by lender.
Asset-based paths exist when deposit history is disrupted. If a construction project has interrupted a borrower’s normal deposit pattern, an asset allowance path — qualifying on liquid assets divided by 36, 60, or 84 months — or an assets-only path, requiring liquidity equal to the loan amount plus costs, can substitute for a clean deposit history. These paths apply on primary and second homes and cap at 80% loan-to-value.
Why Bank Statement Underwriting Fits This Borrower Population So Well
Self-employed workers made up 10.1% of all employed Americans as of June 2026, according to the Bureau of Labor Statistics. That’s roughly 1 in 10 working Americans. Construction runs one of the highest self-employment concentrations of any industry. This is exactly the population bank statement underwriting was built to serve: business owners, contractors, and builders. Their traditional personal-income documentation can understate real cash flow because of legitimate deductions and business structuring.
Non-QM’s footprint in the broader mortgage market has grown alongside this population. Weighted average credit scores on non-QM collateral pools sit in the mid-700s, with loan-to-value ratios around 70% and debt-to-income averaging in the low 30% range, according to Scotsman Guide’s Q3 non-QM issuance report. That’s a credit profile that runs counter to the “risky borrower” stereotype some investors assume comes with non-QM paper.
Across files placed through the wholesale network, a pattern tends to repeat on construction-adjacent bank statement borrowers. They typically show strong liquidity and thin recent-tax-return income. Their collateral timeline is also harder to predict than their income timeline. The files that move cleanest are the ones where the borrower’s deposit history is refreshed close to the CO issuance date. It shouldn’t be left to sit for months while the building finishes.
A Working Example of the Math
Consider a self-employed general contractor buying a newly finished spec home for personal use, priced at $3,200,000. Business deposits over the trailing 24 months average a certain monthly figure; after a 40% expense ratio (reflecting a business with one to five employees), qualifying income lands lower than gross deposits would suggest. At this size, the file sits in the $3M-$3.5M primary-residence band — 75% purchase leverage, 720+ credit floor, reviewed under standard (not yet super-jumbo overlay) terms since it falls under the $3,500,000 primary-residence overlay line.
If the same contractor instead wanted to buy a $4,600,000 new-construction property, the file crosses into the $4M-$5M band: leverage drops to 65% and the loan enters case-by-case review before submission, with the super-jumbo overlays — 700 credit floor, clean housing history, capped acreage — applying in full. The certificate of occupancy still has to be in hand, or a TCO with a confirmed expiration date well past the anticipated closing.
Property investors weighing this against a rental-income-based approach for a different property might find DSCR financing a more direct fit. This works once a new-construction property is finished and rented. DSCR loans qualify primarily on the property’s rental income covering the payment, subject to lender guidelines. They don’t rely on the borrower’s personal deposit history. The two approaches solve different problems. Bank statement financing fits a borrower buying or building a home tied to personal or business cash flow. DSCR fits a completed rental property that generates its own income stream.
Tax treatment of proceeds and deductions can depend on how funds are used and how title is held; investors should keep clear records and speak with a qualified tax professional before relying on any deduction.
Frequently Asked Questions
Does the lender re-check bank statements if construction runs long? Often, yes. If months pass between the initial statement pull and the CO issuance, a refreshed lookback is common, since deposit history from early in the build may not reflect current income by the time the permanent loan is ready to fund.
Can a temporary certificate of occupancy close the loan? Sometimes, but it carries real risk. A TCO is typically valid for a limited window, often around 90 days, and if the permanent CO isn’t issued before it expires, the file can stall mid-process. Confirming the TCO’s expiration date against the expected closing timeline matters.
How does an expense ratio affect a contractor’s qualifying income? It reduces gross business deposits by a fixed percentage before the remainder counts as income, with the percentage generally scaling based on business size and whether the business has employees or sells products — a leaner service operation typically sees a smaller reduction than a larger business with staff or product sales. Personal transfers from the borrower’s own business count in full, without that reduction applied again.
Is there a cap on cash-out for a self-funded new build? Cash-out is often tied to documented construction cost rather than finished market value, particularly soon after completion. Seasoning and cash-out limits vary by program, and appreciation between the build and the refinance doesn’t automatically convert to available proceeds.
What if deposit history doesn’t reflect current income at all? An asset-based path may apply — qualifying on liquid assets divided over a set number of months, or an assets-only approach requiring liquidity equal to the loan amount plus costs. These run on primary and second homes and cap at 80% loan-to-value.
A borrower or investor may be weighing two options for a finished construction property: a super jumbo bank statement approach or a rental-income path. Lendmire can help compare both. This includes how the deposit calculation, collateral documentation, and leverage bands actually apply to that specific file.
