Super Jumbo Bank Statement Loans In South Carolina — The Quick Read: These are large mortgages, generally above the $2 million range, that qualify a self-employed or high-net-worth borrower off deposit history instead of traditional personal-income documentation. Size runs from $300,000 up through wholesale programs that carry files as large as $30,000,000 on tiered leverage ladders, with credit, reserve, and documentation rules tightening as the loan size climbs. Above roughly $4,000,000, every file gets reviewed case by case before it’s even submitted. South Carolina carries no special rule set for this product — the mechanics below are the same wherever the property sits, with one licensing note near the end that matters specifically for South Carolina borrowers.
Key Takeaways
- Qualifying income comes from 12 or 24 months of bank deposits, not traditional personal-income documentation. – “Super jumbo” is not a federal category — it’s the point where a lender’s own overlays get materially stricter, usually once a loan clears the $3.5 million range.
- Leverage steps down as loan size climbs: strong files can reach 90% at the smallest sizes, but the largest loans, north of $10 million, generally land in the mid-50s.
- Business-account deposits absorb an expense ratio before they count as income; personal-account deposits generally don’t.
- Above roughly $4,000,000, files move to manual, case-by-case underwriting before anyone submits them anywhere.
What Actually Makes a Loan “Super Jumbo”?
There’s no government line that separates a jumbo loan from a super jumbo one. It’s a lender overlay, not a regulatory tier, and it moves depending on which wholesale program is reviewing the file.
In practice, once a purchase or refinance clears somewhere around $3 million to $4 million, credit standards, seasoning rules, and reserve requirements all tighten together. That cluster of tighter rules — not one single dollar figure — is what the industry means by “super jumbo.” Across the wholesale programs Lendmire places files with, the overlay genuinely shifts above $3,500,000 on a primary residence and above $3,000,000 on a second home or investment property. Here’s what that typically means: a 700 credit floor, a clean 24-month housing-payment history, 48-month seasoning on any credit event, and no non-occupant co-borrowers allowed on the file. Final terms still depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
Below that line, bank statement underwriting behaves like any other non-QM file — deposits get totaled, an expense ratio gets applied if the money moved through a business account, and the resulting income figure feeds a standard debt-to-income calculation.
How the Underwriting Actually Works, Step by Step
A bank statement loan trades traditional personal-income documentation for deposit history. Here’s the order underwriters actually work through.
Step one — pick the lookback window. Most files use either 12 or 24 consecutive months of statements. This is a math choice, not a risk grade. A business that’s grown recently often qualifies for more using 12 months, because a 24-month average dilutes a strong current run with weaker older history.
Step two — sort the account type. Personal-account deposits and business-account deposits are not treated the same. Personal deposits generally count without a haircut. Business deposits get reduced by an expense ratio first, because the underwriter has to assume some of that money covers overhead rather than the owner’s actual take-home pay. Transfers from the borrower’s own business into a personal account still count in full — this is one of the more common file-structuring decisions a broker makes, since it can change the qualifying income figure meaningfully.
Step three — apply the expense ratio. On the programs in Lendmire’s wholesale network, business deposits typically run through a fixed ratio that scales with headcount and business type, or an accountant-documented ratio, or a profit-and-loss method capped at 80% of deposits. Ownership of at least 25% of the business is generally required to use its statements at all.
Step four — run the standard ratios. Once average monthly qualifying income is set, the file gets underwritten just like any other mortgage: credit score, debt-to-income up to roughly 50% on most files, and a reserve calculation based on loan size. The documentation method changes; the underlying repayment analysis doesn’t.
The Consumer Financial Protection Bureau’s ATR/QM compliance guide explains the reasoning behind this policy. Before the last housing downturn, low- and no-documentation lending left borrowers with mortgages they genuinely couldn’t afford. That’s why non-QM lenders still have to independently verify repayment capacity, even when a borrower has no W-2.
The Size and Leverage Ladder
Leverage steps down as the loan gets bigger, and it steps down differently by occupancy. Here’s the primary-residence ladder as it typically runs through select wholesale programs, subject to full underwriting on every file:
| Loan Size | Purchase LTV | Credit Floor | Notes |
|---|---|---|---|
| $300K–$1M | Up to 90% | 680+ | Best-available cell, strong file |
| $1M–$2M | 80–85% | 700–720+ | Tightens in $500K bands |
| $2M–$3.5M | 75–80% | 720+ | Super-jumbo overlay begins at $3.5M |
| $3.5M–$4M | 75% | 760+ | Full super-jumbo overlay applies |
| $4M–$6M | Case-by-case, generally 60–65% | 680+ | Every file reviewed before submission |
| $6M–$30M | Case-by-case, 50–60% | 680+ | Bank portfolio program’s own ladder |
Second homes and investment properties generally run a step lower at every size band — a $2 million investment purchase, for example, tops out closer to 75–80% rather than the primary-residence figure, and the super-jumbo overlay for those occupancies kicks in earlier, above $3,000,000 instead of $3,500,000.
Cash-out works the same way, on its own lower scale: unlimited proceeds are available at or below 60% LTV on the portfolio program, but cash-in-hand above 60% caps at $1,500,000. The bank portfolio program, which carries 12-month-statement files up to $30,000,000, has no published cash-out cap but layers its own ladder — 65% to $5,000,000, 60% to $10,000,000, and 55% clear out to $30,000,000, with interest-only capped at 60% or the band ceiling, whichever is lower. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
Structures and Variations Beyond Standard Bank Statements
Not every high-income borrower fits a clean 12-month deposit average, so the wholesale programs Lendmire works with carry a handful of alternate paths.
Asset allowance. Liquid assets divide by 36 months as a supplemental income source when overall debt-to-income sits at or below 60%, or by 60 months when it’s above that. At any loan above $3,500,000, or as a standalone qualification method, assets divide by 84 months instead. This path is primary and second-home only, capped at 80% LTV. Retirement accounts count at 70% of value, or 80% for a borrower over 59½. Business funds, gifts, trusts other than a revocable living trust, unvested stock, and cryptocurrency never count toward the total. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
Assets-only. No debt-to-income calculation at all — the borrower just needs U.S. liquid assets equal to the loan amount, plus closing costs, plus 60 months of any net loss on other residential real estate they own.
Interest-only. Available to 85% LTV with a 700 credit floor on the portfolio program, structured as a 40-year term with a 10-year interest-only period. The bank program caps interest-only at 60% LTV, using 5- and 7-year fixed-period adjustables (a 10-year fixed-period option is fully amortizing instead). Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
Profit-and-loss statements. For borrowers whose bank deposits don’t tell the whole income story, some lenders in the network will accept an accountant-prepared profit-and-loss statement in place of the flat expense-ratio math — capped at 80% of gross revenue as usable income.
For a look at how business-account deposits specifically get treated at this loan size, see how these programs handle business bank accounts on a super jumbo. And for the mechanics of using a shorter statement window, this breakdown of the 12-month statement path covers when it helps and when it doesn’t.
Where the General Rule Breaks
The clean version of the story — 12 or 24 months, apply an expense ratio, run the ratios — has real exceptions.
Statement sequence, not statement count, is what stalls files. A broken sequence or a commingled personal/business account causes more delays and outright declines than the actual number of months reviewed.
Occupancy changes the math, not just the label. A borrower buying a $2.8 million investment property doesn’t get the same leverage as one buying a $2.8 million primary residence — the super-jumbo overlay starts $500,000 earlier for non-owner-occupied purchases.
Above $4,000,000, “underwriting” means a human committee, not an algorithm. Every file at that size gets reviewed case by case before submission, regardless of credit score or reserves on paper. That review can adjust leverage, require additional seasoning, or ask for a larger reserve cushion than the published minimum.
Non-QM is not one risk category. Fully documented and investor-purpose non-QM products have performed noticeably better than alternative-documentation and low-doc products in the same space, according to Scotsman Guide’s coverage of loan performance across the non-QM sector — a reminder that documentation type genuinely affects how a file gets priced and reviewed, even within the same broad product family.
These borrowers aren’t the credit risk the label implies. Scotsman Guide’s reporting on non-QM lending found the average non-QM borrower carried a 776 FICO score in 2024 — essentially on par with conventional conforming borrowers, and non-QM has become the largest securitized non-agency mortgage product in the market. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
The South Carolina Scope Note
Consumer mortgage lending covers primary-residence and second-home loans. Right now, this product runs through a 16-state licensing footprint: Alabama, California, Colorado, Florida, Georgia, Indiana, Michigan, Montana, New Mexico, North Carolina, Ohio, Pennsylvania, Tennessee, Texas, Virginia, and Washington. South Carolina isn’t currently on that list.
Investment-property bank statement financing works through a different licensing lane. That’s because it counts as business-purpose lending, not consumer lending. It moves through Lendmire’s broader wholesale network, which covers 40 markets, including Washington, D.C. If you’re an investor in South Carolina looking at a rental purchase, confirm current program availability first. Don’t assume a specific structure applies. The licensing lane is what changes by state — not the loan math.
Key Terms Defined
Bank statement loan — a mortgage that calculates qualifying income from bank deposits over a set number of months rather than from traditional income documentation or W-2s.
Expense ratio — a fixed percentage subtracted from business-account deposits before the remainder counts as qualifying income, meant to account for overhead the tax return would otherwise show.
Asset allowance — a method of turning liquid assets into monthly qualifying income by dividing the total by a set number of months.
Seasoning — the minimum amount of time that has to pass since a credit event, such as a late payment or foreclosure, before a lender will consider the file.
Case-by-case review — manual underwriting applied above a size threshold, where a committee evaluates the file individually rather than running it through standard automated guidelines.
Frequently Asked Questions
Do I need any conventional personal-income paperwork at all for a super jumbo bank statement loan?
No — that’s the point of the program. Qualification runs on 12 or 24 months of bank deposits instead. Lenders still verify identity, assets, and credit, and the file still goes through a full ability-to-repay review; the documentation method is what’s different, not the underwriting standard.
Why would my qualifying income change just by switching from 12 to 24 months of statements? Because it’s a straight average. If your income has grown in the past year, a 12-month average usually produces a higher qualifying figure than a 24-month average that includes weaker older months. A broker will typically run both and use whichever produces the stronger number for your file.
Is there a hard dollar line where a jumbo loan becomes super jumbo?
No — it’s a lender overlay, not a government-set threshold, and it varies by program. Across the wholesale network Lendmire works with, the meaningful tightening — credit floor, seasoning, reserve rules — generally starts around $3,500,000 on a primary residence and $3,000,000 on a second home or investment property.
Can I use money my business transferred into my personal account?
Yes, generally at 100% of the transferred amount, since it’s already been counted once as business income and simply moved. This is one of the more common ways a broker restructures a file to improve the qualifying income figure without changing anything about the borrower’s actual finances.
What happens if my loan amount is above $4,000,000?
The file goes to manual, case-by-case underwriting before it’s even submitted to a specific program. Leverage, seasoning, and reserve requirements at that size aren’t published as a flat number — they get set individually based on the full file, subject to lender guidelines.
Are you self-employed or a high-net-worth buyer? If your standard personal-income documentation understates what you actually earn, you may be weighing a bank statement structure against a DSCR loan, which qualifies based on the property’s own rental income. Lendmire’s complete DSCR loans guide walks through how that comparison plays out. Lendmire can help compare options across its wholesale network, based on the property, the documentation path that fits your income, and your leverage goals. Nothing here is a commitment to lend, and every figure is subject to full underwriting.
