Can You Get a Bank Statement Loan in Washington With 12 Months of Statements?

The Quick Read: Yes, twelve months of bank statements is a normal, recognized way to document income for a non-QM mortgage, and it works for Washington buyers when the deposits are steady, the credit and reserves are sound, and the lender’s program allows the shorter window. Non-QM means the loan sits outside the Qualified Mortgage box that agency loans follow. The loan is reviewed on documented income under the applicable program, subject to lender guidelines.

• Twelve statements is the shortest common window. Many programs also accept 24, and the choice usually turns on your income trend.
• On a primary residence purchase or rate-and-term refinance, select lenders in Lendmire’s network typically go up to 90% LTV. Stronger files earn the top of that range.
• On an investment property, cash-out typically tops out around 75% LTV. Investment purchase leverage on this documentation varies by lender.
• Loan sizes typically run from $125,000 to $3,500,000, with reserves commonly around six months of the housing payment.
• The window is set by the program, not by Washington law. State rules affect licensing, not how many statements you send.

How Does a 12-Month Bank Statement File Work?

A twelve-month file replaces traditional personal-income documentation with your account history. The lender reads twelve consecutive statements, strips out deposits that are not income, applies an expense factor if the account is a business account, and averages what is left. Trade press describes the typical scenario as 12 to 24 months of personal or business statements showing consistent deposits, with details that vary by lender.

Here is the flow, step by step:

1. Collect twelve consecutive, complete statements. Every page, every month, no gaps. Business, personal or both, depending on the program.

2. Screen the deposits. Transfers between your own accounts, loan proceeds and one-off windfalls come out. What remains is eligible income.

3. Average the eligible deposits over the twelve months.

4. Apply an expense factor to business accounts. The factor reflects the costs of running the business.

5. Underwrite the rest of the file. Credit, assets, reserves, the property and, for the self-employed, proof that the business exists. Trade press notes that non-QM underwriting is mostly manual, so a person reads your file instead of a scoring engine.

Across the wholesale network, the expense factor is the piece borrowers underestimate most. It is lender-specific. It depends on the program, the type of business and how well the business is documented. No one can promise you a universal formula, and any broker who does is guessing.

What Does the Math Look Like?

The math is simple: eligible deposits, minus the expense factor, averaged across twelve months. The table below uses index numbers, not dollars, so you can see the logic. Every input is an illustrative assumption. The 50% expense factor is the example used in trade-press coverage of non-QM lending, not a rule.

Read the last row carefully. The same deposit pattern produces very different qualifying income depending on the account type. A business account with a 50% factor needs about twice the deposits to reach the same income as a personal account with no factor.

Some programs also accept a profit-and-loss statement prepared by a CPA or tax preparer as another income tool. Others use a fixed expense ratio, and an accountant-prepared ratio can sometimes change the result. Ask which version the program uses before you pick a statement set.

Twelve Months or Twenty-Four?

Twelve months fits when your income is climbing. Twenty-four fits when it is steady, seasonal or uneven. Only the most recent year counts in a twelve-month file, so a strong trailing year is not diluted by a slower one before it. A 24-month average smooths out lumpy years, which helps when income swings and hurts when it has recently jumped.

“12 months is always easier” is a myth. It is easier only when the trailing year is your strongest year. If the prior year was better, the shorter window works against you.

Lendmire has a piece How to Pick 12 or 24 Months of Statements for a Bank Statement HELOC. The same trend logic applies to purchase and refinance files.

What Do Lenders Screen For in Those Twelve Months?

Lenders screen for deposits that look like repeatable income. Because a person reads the file, small patterns matter. Expect a reviewer to look at these items:

• Deposit consistency and trend. Steady or rising deposits help. Lumpy or falling deposits lower the average.
• Unexplained large deposits. A big one-time deposit needs a letter of explanation and a paper trail. Without that, it comes out.
• Transfers and loan proceeds. Money moved between your own accounts is not income.
• Mixed accounts. When personal and business money share one account, the lender has to separate them first.
• Overdrafts and returned items. A pattern of them signals cash-flow strain.
• Ownership share. If you own part of a business, income is generally prorated to your share.

There is a reason lenders are strict here. The federal ability-to-repay rule requires a lender to consider eight underwriting factors, including the characteristics of your employment, and that includes self-employment. The CFPB’s compliance guide linked above also says a lender that sees an unidentified deposit must take steps to confirm it is your personal income. So a bank statement loan is not “no documentation.” It is a different set of documents.

How Much Leverage Can You Expect?

Leverage depends on what the property is and how you will use it. Occupancy sets the ceiling. Quoting one number for every property type misleads borrowers, so here are the ranges by transaction. All are typical ranges from select lenders in Lendmire’s wholesale network and are subject to lender guidelines, credit and loan size.

• Primary residence purchase or rate-and-term refinance: typically up to 90% LTV. LTV, or loan-to-value, is the loan amount divided by the property value.
• Primary residence with asset depletion: qualifying from liquid assets instead of deposits runs to about 80% LTV.
• Owner-occupied cash-out (primary residence or second home): typically up to 80% LTV with a fixed expense ratio, or 75% with an accountant-prepared ratio. It never reaches the 90% purchase ceiling.
• Investment property cash-out: tops out around 75% LTV.
• Investment property purchase: varies by lender. Treat any single number you see as one lender’s rule.

Loan sizes typically run from $125,000 to $3,500,000. Reserves are commonly around six months of the housing payment, meaning liquid funds left after closing. Term length follows each lender’s program sheet, so do not assume a longer or interest-only structure comes with this documentation.

Occupancy also decides the paperwork. An owner-occupied file is a consumer mortgage, so TRID disclosure rules apply. A bank statement loan on a non-owner-occupied rental, including a short-term rental, is business-purpose and exempt from TRID. 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.

Rate and payment figures live in the calculator, not in prose. Any calculator estimate is illustrative.

Does Washington Change Anything?

Not for the statement count. Nothing about a twelve-month window depends on being in Washington. The window is a program rule, set by the lender’s guidelines.

State law matters in a different place: who has to be licensed. Washington’s rule on consumer loan licensing exempts loans made primarily for business, commercial or agricultural purposes, unless the loan is secured by a lien on the borrower’s primary dwelling. That is a licensing point for lenders and brokers. It does not change what you send for documentation.

Availability is a separate question. Lendmire’s consumer mortgage licensing covers 16 states, so confirm that your state is covered before you plan around a specific program. If you are buying outside that footprint, the options and the lenders will differ.

One last note: this is about Washington State, not Washington, D.C. Plenty of search results for this topic are for the District, so check which place a page is describing.

If a spouse is on title or on the loan, ask early how the lender handles their income and obligations. Programs differ.

What If You Have a Short History or Uneven Income?

Short history is where program sheets differ most. Some lenders want two years of self-employment. Others accept less when your prior work history is in the same field. Neutral sources do not set a standard here, so the honest answer is that it depends on the lender and the file.

What you can control is the story the statements tell:

• Under two years in business: show a clear prior-industry history, steady deposits and strong reserves. Those help a reviewer get comfortable.
• A new account opened mid-year: you may need to supply statements from the account it replaced, so the full twelve months are covered.
• Seasonal or commission income: the 24-month window often fits better, because a longer average captures a full cycle.
• Declining deposits: lumpy or falling income pulls the average down. Expect the lender to read the trend, not only the average.

A stronger credit profile, a larger down payment and extra reserves can offset some of that. They do not guarantee an outcome. Qualification is subject to lender guidelines, credit approval and property review.

When Does a DSCR Loan Fit Better Than a Bank Statement Loan?

For a pure rental, DSCR often fits better because it reviews the property’s rental income and not you. A bank statement loan underwrites your personal cash flow, so each new loan counts against your debt load. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. DSCR means debt service coverage ratio, the property’s rent divided by its monthly debt obligation.

In practice, many investors split their strategy. They use a bank statement loan for a home they will live in, and DSCR for rentals. It is a common broker view, not a regulatory rule. A self-employed investor whose traditional personal-income documentation shows heavy write-offs can fit a bank statement loan on the home. The same investor often scales better on DSCR for rentals.

Lendmire’s comparison of a DSCR loan versus a bank statement loan for investors goes deeper on that choice. For the full program picture, see the complete DSCR loans guide.

Programs below 1.00 coverage are available through select lenders in the network, but LTV and terms adjust. Falling or uneven deposits do not matter on a DSCR file, because your personal deposits are not the yardstick.

Tax treatment varies; consult a qualified professional before relying on any deduction.

Checklist: What to Gather Before You Apply

Start gathering these months before you plan to apply. Gaps and missing pages cause the most avoidable friction.

• Twelve consecutive statements, every page, personal, business or both
• Proof that the business exists, such as a license, registration or certification where applicable
• Letters of explanation for large or unusual deposits
• A clean separation between personal and business money, if you can manage it
• Credit reports and an honest read of your score
• Documentation of assets and reserves
• A CPA-prepared profit-and-loss statement, if the program allows one
• The prior-year statements too, in case the 24-month window fits better

Stop moving money around in the months before you apply. Frequent transfers between accounts make the deposit screen harder.

LTV: loan-to-value, the loan amount divided by the property’s value.

Reserves: liquid funds you hold after closing, usually counted in months of the housing payment.

DSCR: debt service coverage ratio, a property’s rent divided by its monthly debt obligation.

Asset depletion: a way of qualifying from liquid assets instead of income deposits.
