How Bank Statement Loan ARM Structures Work: 5/6 and 7/6 Options

The Quick Read: A bank statement loan ARM pairs two separate choices. Bank statements decide how your income is verified, and the ARM decides how your rate behaves. A 5/6 holds the rate fixed for five years and a 7/6 holds it for seven. After that, the rate adjusts every six months.

• The first number is the fixed period, not the loan term. The term is typically 30 years, subject to each lender’s program sheet.
• The 6 means the rate adjusts every six months after the fixed period ends.
• Your income and credit are not re-checked at reset. The note’s formula does the work.
• The 7/6 buys two more years of a level payment. The 5/6 usually suits a shorter hold.
• Qualification runs on documented income under the applicable program, subject to lender guidelines.

What Is a Bank Statement Loan ARM?

A bank statement loan ARM is a mortgage that is reviewed around deposits, then carries a rate that is fixed for a set period and adjustable after that. The two features have nothing to do with each other. Think of one as the entrance exam and the other as the contract.

On the documentation side, the lender reviews 12 months of business or personal bank statements. It averages your deposits, applies an expense factor, and arrives at a monthly income figure. Expense factors differ by lender, so no universal formula exists. A self-employed borrower whose traditional personal-income documentation shows far less than the cash that actually moves through the account uses this path.

On the rate side, you pick fixed or adjustable. Across the wholesale network Lendmire works with, both structures show up inside alt-doc programs. Some borrowers assume bank statement loans must be fixed, and that is simply wrong.

Lendmire is a broker. It arranges these loans through select lenders in its wholesale network and does not underwrite or approve them. Every file is reviewed individually by the lender.

How Do You Decode 5/6 and 7/6?

The first number is the number of years the rate stays fixed, and the second is how often it adjusts afterward. The federal consumer-finance regulator’s mortgage key terms explain that format using a 5/1 example. They also note that common fixed periods are 3, 5, 7 and 10 years.

Older loans used a 1 at the end, meaning one adjustment a year. Current ARMs usually use a 6, meaning one adjustment every six months. That is the reason you will see both labels. A 5/1 resets annually, while a 5/6 can reset twice a year.

Here is the mistake people make most often. They read 7/6 as a seven-year loan. It is not. The term is still typically 30 years, so a 5/6 has about 25 years left when the fixed period ends and a 7/6 has about 23.

What Happens Year by Year?

Nothing changes in the payment during the fixed period. The principal and interest payment stays level, just like a fixed-rate loan. Then the first reset arrives, and everything runs on formula.

Plan around the table, not around the label. If you expect to sell or refinance well before year five, the reset may never touch you. If your exit slips, the reset is the point where your plan meets the note.

How Is the Reset Calculated?

At each reset, the servicer takes the index value named in your note, adds the margin, applies the caps, and re-amortizes the payment over the remaining term. The index is a published benchmark. Many current ARMs use SOFR-based averages, which look backward over a 30-, 90- or 180-day window. That means a reset reflects recent rates, not a forecast.

The margin is the extra percentage the lender adds to the index. It usually stays the same for the life of the loan. The index is the part that moves.

Caps limit how far the rate can move. They are usually written as three numbers: the first adjustment, each later adjustment, and the lifetime limit. A first-adjustment cap can be larger than the later ones, so read all three numbers before you commit. Pricing and available terms vary by lender, borrower profile, property type, and full underwriting review.

Cap sets, margins and floors on alt-doc ARMs are note-specific. Most programs we place files with spell them out in the note, and they do not match one standard. Ask for the cap triplet, the margin, the index and the lookback in writing before you pick a lender.

Does the ARM Change How Bank Statement Income Is Calculated?

No. Documentation and rate structure are independent, and the table below shows where each choice lives.

Your deposit average sets how much loan you can carry. The ARM sets how the cost of that loan moves. One does not alter the other.

Here is the part that surprises people. Your income is not re-checked at reset. Neither is your credit. The rate changes by formula, and the lender does not ask whether your business had a good year.

That cuts both ways. You cannot lose the loan because deposits dipped, but you also cannot ask for relief because the payment rose.

How Does Qualifying Work on an ARM?

The lender decides whether the payment is affordable at the start, using the documented income from your statements. How it tests that payment varies by lender. Some qualify you on the note payment. Others use a higher, stressed payment so the file survives an adjustment.

This is one of the most important questions to ask early. Two lenders can reach different loan amounts from the same twelve months of deposits, partly because of expense factors and partly because of the qualifying payment. Because alt-doc loans fall outside the standard rules that give conforming loans a safe harbor, each lender makes its own judgment of your ability to repay. The CFPB’s compliance guide says that standard-rule loans are tested at the highest rate that may apply in the first five years. A 5/6’s first reset lands just after that window. A 7/6’s lands later still.

Typical program parameters on bank statement files, subject to lender guidelines:

• Up to 90% LTV on a primary-residence purchase or rate-and-term refinance, with the top of the range going to stronger files.
• Up to 80% LTV on an owner-occupied cash-out, using a fixed expense ratio, or 75% with an accountant-prepared ratio.
• Around 75% LTV on an investment-property cash-out.
• Loan sizes roughly from $125,000 to $3,500,000.
• Reserves commonly near six months of the housing payment.

Investment-property purchase leverage on bank statements varies by lender. Investors who want property-rent-based lender review usually look at DSCR programs instead. Lendmire’s complete DSCR loans guide covers that side.

Which Rules Apply to Your Property?

Occupancy decides the paperwork. A primary residence or second home is a consumer mortgage, and consumer mortgage disclosures apply. A bank statement loan on a non-owner-occupied rental, including a short-term rental, is business-purpose and exempt from those consumer disclosures. Business-purpose investor loans are reviewed differently from a standard owner-occupied mortgage.

Do not mix the two. The same ARM label can sit on either one, but the leverage, the disclosures and the lender’s questions differ. The consumer lane at Lendmire covers 16 states.

5/6 or 7/6: Which Fits Your Hold?

The 7/6 gives you two more years before any reset, and the 5/6 usually starts with the more attractive entry terms. No neutral source publishes the spread on alt-doc loans, so this comparison is qualitative. Your actual terms come from the lender’s sheet.

Match the structure to the plan, not to a more affordable starting number. A business owner planning to sell the company in four years has a different answer from one who plans to hold the home for a decade. If your exit has a hard deadline, buy the extra two years. If it is soft, expect the world to run late.

Lendmire’s piece How a 5/6 or 7/6 ARM Lowers a Bank Statement Loan Payment goes deeper on the entry-payment side. Borrowers with very large balances may prefer the comparison in 5-year vs 7-year ARMs on super jumbo bank statement loans.

What Does Payment Shock Look Like?

Payment shock is the gap between your last fixed payment and your first adjusted one. It depends on the index, the margin and the caps. You do not need dollar figures to see the shape of it.

Say you hold a rental that covers its full monthly obligation at a 1.20x coverage ratio. If the adjusted payment rises about 20%, that coverage falls to 1.00x. A further rise pushes it below 1.00x. That is the test: run the worst payment your caps allow against the rent or income that pays for it.

Caps do not make a payment affordable. They only limit the damage. A borrower should consider an ARM only if the payment is affordable even at the maximum amount.

The rate can also fall. If the index drops, your rate follows, but only down to the floor, and never below the margin. Do not count on that.

Where Does the Rule Break?

Several edge cases change the picture:

• Interest-only periods. Some alt-doc ARMs include an interest-only stretch, and terms follow each lender’s program sheet. When it ends, the payment steps up on top of any rate change. That layering gives the lowest early payment and the biggest later jump. Interest-only is also one reason a loan ends up outside the standard mortgage box, because the CFPB’s compliance guide lists interest-only among the features that disqualify a general standard-rule loan.
• Prepayment penalties. Some investor-oriented loans carry them. A penalty can trap you in the loan if your plan is to refinance at the first reset.
• No conversion. Standard alt-doc ARMs generally do not convert to a fixed rate. Switching means a new application and a fresh review of your deposits.
• Naming drift. You may see 5/1 and 5/6 in the same conversation. Confirm the adjustment interval, because annual and semiannual resets feel different.
• Term length. Terms follow each lender’s program sheet. Never assume an extended term is on offer.

How Do You Plan the Exit?

Plan the exit before closing, not at reset. A refinance is not a promise. It depends on future value, your credit and the market on the day you apply.

Here is what trips people up. The next lender will read your deposits again. If your business income looks different from the first time, your refinance might not look like your purchase did. Keep clean statements through the hold, and know what your prepayment terms say.

Lendmire’s brokers see this pattern often. Borrowers pick the structure and skip the exit plan. The stronger files usually pick a fixed period longer than their honest timeline.

Today’s alt-doc loans are fully underwritten for repayment, which is a safeguard that earlier low-documentation lending lacked. The reset risk itself has not gone away.

Key Terms Defined

Index: A published benchmark rate that moves with the market and feeds the reset formula.

Margin: The fixed percentage the lender adds to the index to set your rate.

Fully indexed rate: The index plus the margin, which is where the rate lands once any starting discount is gone.

Cap: A limit on how far the rate can rise or fall at one adjustment or over the loan’s life.

Floor: The minimum level the note allows the interest rate to reach, no matter how far the index falls.

Re-amortization: Recalculating the payment at each reset so the balance still pays off over the remaining term.

Expense factor: The percentage a lender subtracts from business deposits to estimate what is left as income.

Common Misconceptions

• The 5 or 7 is the loan term. It is the fixed period only.
• The 6 means once a year. It means every six months.
• My income gets re-checked at reset. It does not. The formula runs on its own.
• ARMs only go up. They can fall with the index, down to the floor.
• Caps mean the payment cannot hurt. A capped worst case can still be unaffordable.

Next Steps

Qualification runs on documented income under the applicable program, subject to lender guidelines, and nothing here is a commitment to lend. Tax treatment varies; consult a qualified professional.

The right structure is the one whose first reset arrives after your plan has finished, not before.
