Super Jumbo Bank Statement Loans In Key Largo: How The File Is Read

The Quick Read: Yes, self-employed buyers can qualify on deposits instead of traditional personal-income documentation, even on very large Key Largo purchases. Through select wholesale programs, subject to full underwriting, files run from $300,000 to $30,000,000. Leverage steps down as the loan grows, and anything above $4,000,000 is reviewed case by case before it is submitted.

What Is a Super Jumbo Bank Statement Loan?

It is a mortgage for a self-employed borrower, sized well above the standard jumbo range, where income comes from bank deposits instead of traditional personal-income documentation. Nobody in government defines “super jumbo.” It is a market label, and each lender draws the line in its own place.

What is defined is the conforming loan limit, the ceiling for loans that big agency buyers will purchase. Florida Realtors reports the current baseline at $832,750, with Monroe County, home of Key Largo, at $990,150. That is the only Florida county with the higher high-cost limit.

Even that higher ceiling sits below a lot of Keys waterfront and canal-front pricing. So plenty of Key Largo buyers land in jumbo territory. Many land in super jumbo.

The people who use this product are founders, physicians, attorneys, entertainers, athletes, and investors. Their traditional personal-income documentation understates what they actually earn. Write-offs shrink taxable income. Deposits tell the fuller story.

How Is the File Actually Read?

The underwriter works through five steps: statements, expense ratio, credit and debt, reserves, then the property. Here is each one.

Step 1: Twelve or twenty-four months of statements. Across our wholesale network, borrowers choose 12 or 24 consecutive months of personal or business statements. The bank portfolio program uses 12. Statements must be consecutive. A printed transaction history does not substitute.

The window matters. A 12-month look leans on your recent run. One huge month carries more weight. A 24-month look smooths the swings, which helps if your income is lumpy and hurts if you are climbing fast.

Step 2: The expense ratio. A business account’s deposits are not your take-home pay. Payroll, inventory, and overhead come out first. The expense ratio is the slice the lender removes before deposits count as income.

Programs in the network use fixed ratios:

• The fixed expense ratio is lowest for a service business with no employees.
• It steps up for a business with 1 to 5 employees.
• It is highest for a business with 6 or more employees, or for any product business.

Or you can supply an accountant-provided ratio. A profit-and-loss method exists too, capped at 80%. Business statements require at least 25% ownership.

Step 3: Personal accounts and transfers. Money you move from your own business into your personal account counts in full. That is a big edge for owners who pay themselves by transfer. It can make the personal-statement route cleaner than the business route.

Qualifying income is eligible deposits divided by the number of statement months, after the ratio. Simple on paper. The work is in sorting eligible deposits from noise like transfers between your own accounts.

Step 4: Credit and debt. The portfolio program’s floor is a 660 credit score. The bank program’s is 680, and both rise to 700 above the super-jumbo line. Debt-to-income (your monthly debts as a share of qualifying income) can run to 50%.

For context, Scotsman Guide reports that non-QM borrowers averaged a 776 credit score in one recent vintage, with average loan-to-value near 75%. Market surveys describe the typical borrower. The floors above are the network’s actual guideline minimums, through select wholesale programs. Strong-credit borrowers dominate this space, so don’t assume a bank statement file is a weak file. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.

Step 5: Reserves and the property. Reserves are liquid funds left after closing. The network typically wants 3 months of housing payments to $500,000, 6 months to $1,500,000, and 9 months above that. Add 2 months per additional financed property, up to a 12-month maximum. First-time investors are typically asked for 12 months.

Here is what most first-time super jumbo borrowers miss: the property gets read as hard as you do. Appraisal, condo status, flood zone, and insurance all feed the decision.

How Much Can You Borrow, and at What Leverage?

Leverage (loan-to-value, or LTV, the loan as a share of the property’s value) shrinks as the loan grows. Each figure below is a ceiling on a purchase, through select wholesale programs, subject to full underwriting.

Credit floors climb with the size, typically from 680 or 700 at lower sizes to 720 through the mid-range. Some bands ask for 760. Files above $4,000,000 are reviewed case by case before submission, so the numbers in that row are starting points, not promises. Above $6,000,000 the bank portfolio program stands alone, and its ladder runs 60% to $10,000,000 and 55% to $30,000,000, again on review.

The bank program’s own ladder begins above $4,000,000 and overlaps the portfolio program up to $6,000,000. Both are shopped by the broker. You don’t pick one and hope.

Cash-out refinances run lower than purchases. Proceeds are unlimited at or below 60% LTV. Above 60%, the portfolio program caps cash in hand at $1,500,000. There is no published cap on the bank program. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.

Interest-only is available too. The portfolio program allows it to 85% LTV with a 700 credit floor, on a 40-year term with a 10-year interest-only period. The bank program allows it at 60% or the band’s ceiling, whichever is lower. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.

Where the Rules Get Tighter

Above $3,500,000 on a primary residence, and above $3,000,000 on a second home or investment property, extra overlays kick in:

• 700 credit floor
• Clean housing history over the prior 24 months
• 48 months of seasoning after any credit event (seasoning is the waiting period since the event)
• U.S. citizens and permanent residents only
• No non-occupant co-borrowers
• No rural property, and ten acres maximum
• Cash-out proceeds cannot count toward reserves

None of these are exotic. Together they mean a borderline file that works at $1,500,000 may not work at $3,500,000. Plan for that before you fall in love with a house.

Where the General Rule Breaks in Key Largo

Four Key Largo situations bend the standard file.

Flood exposure. Monroe County reports 30,268 flood policyholders and more than $7.5 billion in insured value under the National Flood Insurance Program. That concentration matters to you. Flood coverage is a real line in the monthly obligation, it affects reserves, and it is required when a mortgaged building sits in a Special Flood Hazard Area. Get insurance quotes early. Insurance costs vary by property, elevation, and carrier, so treat them as a file input, not an afterthought.

Short-term rental income. Key Largo runs on visitors. If you plan to rent nightly, understand that the standard rent schedule appraisal form (Form 1007) was built for long-term leases. A nightly rate multiplied by thirty is not “market rent.” Lenders that finance short-term rentals typically lean on booking-platform history instead. Short-term rental rules can vary by city, county, HOA, and property type, so investors should confirm local rules before relying on projected rental income.

Condos and condotels. Warrantable condos can reach 85% LTV in the network, and non-warrantable condos reach 80%. Condotels (hotel-style condo units) are lower: 75% on a purchase and 65% on a cash-out, and 50% on the bank program. Keys condo buildings often mean higher scrutiny of the association’s finances and insurance.

Second homes are one-unit only. A duplex you plan to live in part-time doesn’t fit the second-home box. Investment property allows 2 to 4 units, up to 85% in the lower size bands.

That covers the broad picture. The mechanics for Key Largo specifically live in Lendmire’s bank statement loans in Key Largo page.

No Deposits to Show? Other Ways In

Some borrowers don’t fit the deposit model at all. A retired founder with a large portfolio is a common example. Two asset-based paths exist through select wholesale programs.

Asset allowance. The lender divides your liquid assets by 36, 60, or 84 months to create qualifying income. Use 36 when DTI is at or below 60%, 60 when it is above, and 84 for a standalone file or any loan above $3,500,000. It applies to primary and second homes only, capped at 80% LTV. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.

Assets-only. No DTI is calculated. You qualify when U.S. liquid assets equal the loan amount plus closing costs plus sixty months of any net loss on other residential property.

Retirement accounts count at 70% of value, or 80% at age 59½ and older. Business funds, gifts, most trusts, unvested stock, and cryptocurrency never count. (Yes, crypto. It surprises people.)

If you are buying a Key Largo rental, a third route is worth a look. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. It is designed for non-owner-occupied investment property and is reviewed differently from a standard owner-occupied mortgage. Our complete DSCR loans guide walks through it. Programs below 1.00 coverage are available through select lenders in the network, though leverage and terms adjust.

A Quick Scenario

Picture a physician-owner of a multi-location practice buying a second home on a canal at a price in the $2M–$2.5M band. Traditional income documentation shows modest income after depreciation and equipment write-offs. Business deposits are strong.

The broker checks the second-home column: 80% ceiling on a purchase, with a 720-plus credit expectation. The lender runs 24 months of statements to smooth a seasonal dip. The practice has six employees, so a 50% expense ratio applies unless the accountant supplies a lower documented one. Reserves land at 9 months, since the loan is above $1,500,000. Flood quotes go in early.

Now change one thing: the price jumps into the $4M–$5M band. Leverage drops to 65% on review, the credit floor moves up, and the whole file is reviewed before submission. Same borrower, very different structure. That is why the size of the loan changes the strategy.

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.

Seasoning: The waiting period a lender requires after a credit event or between two transactions.

Special Flood Hazard Area: A mapped zone with elevated flood risk, where flood insurance is required on a federally regulated mortgage.

Deciding What to Do Next

Start with a simple question: which income story is easiest to prove? If your deposits are clean and consistent, use them. If your assets are large and your income is irregular, look at asset paths. If the property itself rents well, price out DSCR too. The right answer changes the loan size, leverage, and cost.
