How 12 vs. 24 Months of Statements Affect a HELOC With a Loss on Returns

The Quick Read: A loss on a tax return does not set the income on a bank statement HELOC, because the file reads deposits instead of the return’s net line. The 12-month window suits rising or recently recovered income, and the 24-month window suits steady income or a recent dip that would drag a short average down. Either way, the underwriter still asks why the return shows a loss.

• Twelve months averages only the most recent year, so an older weak year drops out.
• Twenty-four months smooths seasonality but can expose a decline or dilute a recovery.
• A loss from depreciation is a paper loss, and deposit history supports that explanation.
• Credit, combined loan-to-value (CLTV), debt-to-income (DTI), and vesting still apply under either window.
• Which window a lender accepts is a program decision, and every figure here is subject to lender guidelines.

The honest answer comes first. Choose 12 months when the recent deposits are your strongest evidence. Choose 24 months when income is steady and a short window would catch a soft stretch. The window is a tool for presenting income fairly, not a way around a business that is actually shrinking. Lendmire brokers these lines through select wholesale partners and does not lend directly. Availability is limited to the 16 states where its full-service mortgage operation runs, which is narrower than its 41-market DSCR footprint (40 states plus Washington, D.C.).

Why Does a Return Show a Loss When the Account Shows Cash?

Usually because the return counts expenses that never left your bank account. Depreciation is the biggest one on rentals. BiggerPockets explains that a rental often shows a passive loss for tax purposes, and that adding back depreciation and amortization reveals the true operating result. BiggerPockets also notes that residential rental property is depreciated over 27.5 years, so that deduction repeats every year.

Aggressive planning widens the gap. Cost segregation plus bonus depreciation can create large paper losses early in ownership. A lender reading the net line on Schedule C or Schedule E sees a borrower losing money. A lender reading deposits sees cash coming in. That is why a deposit-based line exists.

A loss may not even be deductible. IRS Publication 925 says a passive activity loss is generally not allowed, with a $25,000 allowance for active participants that phases out between $100,000 and $150,000 of modified adjusted gross income. Suspended losses still show up on the return, and the underwriter may see them. Tax treatment varies by borrower and property; consult a qualified tax professional before relying on any deduction.

Side-by-Side

The table compares the two statement windows on a deposit-based HELOC file. Program rules vary by lender, and the table reflects typical practice, not a guarantee.

The bottom two rows matter most. The window changes the income figure. It does not change what the property can hold, who can hold title, or how much equity is available.

How Does a Loss Year Interact With the Statement Window?

Match the tax year of the loss to the months you submit. That mapping decides which window helps.

• Loss year sits just outside a 12-month window. The short window may never touch it. Deposits in the most recent year carry the file.
• Loss year straddles a 24-month window. Weak deposits from that period pull the average down, though stronger recent months can offset them.
• Recovering deposits. Twelve months usually reads higher. Twenty-four months dilutes the recovery with the weak stretch.
• Flat deposits. The two windows land close together, so the lighter paperwork load of 12 months often wins.
• Declining deposits. Neither window rescues the file. Many programs can shorten a 24-month average when deposits are falling, and a falling trend is flagged under either one.

Here is a worked example with no dollar figures. Picture a borrower whose first year had a depreciation-driven loss and weak deposits, and whose second year ran noticeably stronger. On a 12-month window the file averages only the strong year. On a 24-month window the weak first year drags the average down, so the qualifying income reads lower. The 12-month window is the better presentation. Now flip it. Picture a borrower with one unusually big spike in the latest year after a flat history. A 24-month window spreads the spike out and gives the underwriter a steadier read.

Some lenders will run both calculations and use the stronger one. Ask your loan officer whether the program does this before you submit.

How Does the Deposit-Based Review Actually Work?

The lender replaces the return’s net figure with an average of eligible deposits. It strips out transfers between your own accounts, loan proceeds, and other non-income credits, then applies an expense factor if the statements come from a business account. Scotsman Guide describes the typical setup as 12 to 24 months of personal or business statements, with income qualified through a standard expense factor or through a profit-and-loss statement from a third-party tax professional. Its example uses a 50% factor, which is a market illustration and not a Lendmire program figure. The lender sets the factor, not the borrower.

Deposits have to be identified as income, not merely totaled. Large or unusual deposits need an explanation. Overdrafts and returned items get reviewed. Expect to provide every page of every account you count, plus proof of self-employment or business ownership.

The qualifying income then runs through a DTI test. On the network’s HELOC programs, DTI tops out at 50%, with 45% as the ceiling for credit profiles from 600 to 679, and anything above 45% needs at least a 680 score. The line is qualified on the interest-only payment calculated on the maximum draw. Those figures are the network’s, not a federal formula.

What Does the Underwriter Still Check Beyond Income?

A loss on the return can raise viability questions even when it never enters the income math. Two consecutive loss years raise them harder. A short written explanation that ties the loss to depreciation or timing, backed by steady deposits, changes how the file reads.

If a year-to-date profit-and-loss statement is part of the file, it has to reconcile with the statements. A P&L showing strong income against statements showing thin deposits is a problem in either window. A 24-month window gives more months to reconcile, so more chances for a mismatch to appear.

Business versus personal accounts matters too. Business statements carry an expense factor. Personal-account deposits generally do not, though the lender decides how to sort rental deposits from business revenue. A borrower with a business less than 24 months old may be limited to the 12-month path simply because the history does not exist yet.

What Limits Come With the Line Itself?

The window only fixes the income side. The collateral side has its own limits, and they are the same under either window.

On an investment property, the line caps at 70% CLTV and $500,000, with a minimum credit score of 700. Investment lines run a 5-year interest-only draw followed by a 25-year repayment. On a primary residence, the CLTV ceiling reaches 90%, but only at a 720 credit profile and up to $500,000. Lines above $500,000 are primary-residence only, need a 700 score or better (720 on the longer-runway structure), cap at 75% CLTV, and require a full appraisal. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.

The structure is a standalone first or second lien. At least 75% of the line is drawn at closing, and pricing floats and does not convert to fixed. Lines at or below $500,000 ordinarily run automated valuation without a traditional appraisal, and a borrower may request a full appraisal anyway. Each figure applies within its own program’s terms and is subject to full file review.

Better income does not raise the ceiling. A borrower with excellent deposits on an investment property still stops at 70% CLTV. Window choice moves the DTI number. It does not move the leverage cap.

When the 12-Month Window Is the Better Fit

Twelve months works best in these situations:

• Deposits have grown over the past year and the older months are weaker.
• A loss year or a weak stretch sits just outside the most recent twelve months.
• The business is under two years old.
• You want less documentation to organize and reconcile.

The risk is that a single strong year can look like a spike. If the underwriter reads it that way, the file gets more questions. A short rolling-forward strategy sometimes helps: if one weak month sits at the edge of the window, waiting a month lets it roll out of the average.

When the 24-Month Window Is the Better Fit

Twenty-four months works best in these situations:

• Income is steady or seasonal, and a short window might land on a slow stretch.
• The most recent months dipped for a one-off reason, and the earlier months show the normal level.
• A paper loss from depreciation sits inside the window, and two years of consistent deposits support the explanation.
• The latest year has an unusual spike you would rather not lean on.

The cost is documentation. Twice the statements means twice the sourcing, and any decline in the second year stays visible.

When Neither Window Helps

A real revenue decline is not fixed by choosing a window. If deposits are falling under both, the file reads weak under both. In that case, the stronger path may be the property itself. A DSCR cash-out refinance is closed-end and qualifies primarily on property-level rental income covering the payment, subject to lender guidelines, so the return’s loss is not the income source. DSCR files typically need little or no personal income statement review, which is why 12-versus-24 is a HELOC question and not a DSCR one. A DSCR loan also allows LLC vesting, subject to program terms, while a HELOC does not. Lendmire’s complete DSCR loans guide walks through that alternative.

Vesting is the practical catch. On the HELOC programs, title must sit with the individual borrower or an inter vivos revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. A property already deeded to an LLC needs a vesting change or a DSCR cash-out instead. Eligible property types include single-family, 2-4 units, PUDs, townhomes, and condominiums, including non-warrantable. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not eligible. A borrower is limited to three lines, and anyone owning more than 15 financed properties is not eligible.

Pre-Submission Checklist

1. Pull every statement page for every account you plan to count, with no missing pages.

2. Mark and explain large deposits, transfers, and loan proceeds before the underwriter has to ask.

3. Write a short note tying the return’s loss to depreciation or timing.

4. Reconcile any P&L against the statements month by month.

5. Ask whether the program will run both windows and use the stronger result.

The Verdict

Pick the window that shows your income most accurately, not the one that sounds more thorough. Recent strength favors 12 months. Steady income or a recent dip favors 24. A loss on the return does not decide it either way, because the deposit-based file reads cash, though the loss will still prompt questions. For more on the choice itself, see Lendmire’s piece How to Pick 12 or 24 Months of Statements for a Bank Statement HELOC, and for how the window moves the line amount, see how 12 versus 24 months of statements change your bank statement HELOC limit.
