Bank Statement HELOC Lenders to Pay for a New Deck

The Quick Read: A new deck can be funded with a home equity line reviewed on documented bank deposits under the applicable program, subject to lender guidelines, if your home has enough equity after the full line limit is counted, your credit clears the tier, and the line is sized close to the project.

• Self-employed owners can document income with deposits instead of tax returns, but equity, credit, property type and debt load still decide the outcome.
• Most of the line is drawn at closing, so a deck-sized line behaves more like a loan than a flexible credit card.
• Pricing floats for the life of the line, and the payment steps up when repayment starts.
• Which lender fits depends on your property, credit profile and leverage need. A broker can shop several wholesale lenders and match the file to a program.

What Is a Bank Statement HELOC?

A bank statement HELOC is a home equity line of credit where the lender reads your deposits instead of your tax returns. Everything else works like a standard line. It is a lien on your home, you borrow against a limit, and the pricing is variable.

Self-employed owners often show low taxable income because business deductions shrink the bottom line. Their bank accounts can tell a different story. These lines exist for that gap.

The product is proprietary. Each lender sets its own statement window, expense factor and deposit screening, and those rules change from one program to the next. A year or two of statements is the usual ask. Lendmire is a mortgage broker, not a lender. It arranges these lines through select wholesale lenders, so the matching work happens before you apply.

How Do Underwriters Treat Your Statements, Step by Step?

Underwriting follows a set order. Each step can stop the file, so knowing the order helps you prepare.

Step 1: Deposits are totaled. The underwriter adds up eligible deposits across the statement window and averages them. Business and personal accounts can both be used, depending on the program.

Step 2: Non-income deposits are screened out. Transfers between your own accounts, refunds, and loan proceeds do not count as income. Commingled personal and business money makes this step harder, because the underwriter has to separate it.

Step 3: An expense factor is applied. The lender subtracts an assumed share of business expenses from the averaged deposits. What is left is qualifying income. The factor varies by lender and by business type.

Step 4: Debt-to-income is tested. On this network, the maximum DTI is 50%. For credit profiles from 600 to 679 the maximum is 45%, and a ratio above 45% requires a score of at least 680. The 600 floor applies to primary residences only, while second homes start at 640 and investment lines at 700, so second-home and investment files enter this band only at their own minimums, if at all. The line is qualified on the interest-only payment calculated on the maximum draw, not on what you plan to borrow.

Step 5: Equity is tested. Your existing mortgage balance plus the full line limit, divided by the home’s value, gives combined loan-to-value, or CLTV. Because the full limit counts, a line sized larger than the project raises your CLTV and can limit how much you qualify for.

Step 6: Value is confirmed. Lines at or below $500,000 ordinarily use an automated valuation with no traditional appraisal. A higher CLTV may require a second valuation, and you can request a full appraisal at any time. Every line above $500,000 requires a full appraisal.

A falling deposit trend can draw a letter of explanation or a shorter lookback. Keep your statements clean for months before you apply.

How Much Equity and Credit Does a Deck Line Need?

Across the select wholesale lenders in Lendmire’s network, maximum CLTV depends on occupancy and credit tier. The ceilings are not the same for a home you live in and a rental.

• Primary residence: The ceiling reaches 90% CLTV only at a 720 or better credit profile, with a line up to $500,000. A 700 profile reaches 85% CLTV up to $500,000, and 75% up to $750,000 is available at 700 or better on the 3-year-draw program, or at 720 or better on the 5-year-draw program. At 640 the ceiling is 80%. At 620 it is 70% on a line up to $400,000, and at 600 it is 60%.
• Second home: The ceiling reaches 90% CLTV only at 720 or better, with a line up to $500,000. At 640 it is 75%, and the minimum score is 640.
• Investment property: The ceiling is 70% CLTV, the minimum credit score is 700, and the maximum line is $500,000.

Lines run from $25,000 to $750,000. A line above $500,000 is primary-residence only. It needs a credit profile of 700 or better (720 on the 5-year-draw program, described below), caps at 75% CLTV, and requires a full appraisal.

Credit is scored on a single bureau model keyed to the primary wage earner. The report can be no more than 90 days old at closing, and rescores are not allowed. A bankruptcy needs four years of seasoning from discharge or dismissal. These are guideline ranges, and every file is underwritten individually.

Why Do Most Deck Lines Behave Like Loans?

At least 75% of the line is drawn at closing. That one rule changes how you should size a deck project.

Say you hold a primary residence with a first mortgage at about half its value. You open a line equal to roughly 15% of the home’s value. Your CLTV counts the full line limit, so you land near 65%, even if you only plan to spend part of it. That sits well below the 75% CLTV available to a 700 profile on a line up to $750,000, and below the 85% available up to $500,000, but it shows why a large contingency cushion costs equity.

Because most of the line is drawn up front, you pay interest on most of the balance from day one. The draw period is interest-only, so nothing goes toward principal. Sizing the line to the contractor quote plus a modest contingency keeps idle borrowed money to a minimum.

Two draw structures exist across the wholesale programs Lendmire places files with:

• The 3-year-draw program: three years of interest-only draw, then a 17-year fully amortizing repayment.
• The 5-year-draw program: five years of interest-only draw, then a 25-year fully amortizing repayment. This is the longer-runway structure.

Investment lines run only on the 5-year-draw structure. A few states shorten both windows. After closing, a subsequent draw carries a $1,000 minimum on the 5-year-draw program, with a higher minimum in some states.

What Changes After the Draw Period Ends?

The payment jumps. The CFPB’s HELOC explainer says you can no longer borrow once the draw period ends. Repayment then often runs over 10 or 20 years, and monthly payments are often significantly higher once it starts.

The same agency’s HELOC brochure adds two points. Interest-only draw payments put nothing toward principal. With a variable rate, payments can change even if you never draw again.

On this network the pricing floats through both the draw and repayment periods and never converts to fixed. Some HELOCs elsewhere let you lock part of the balance at a fixed rate. These programs do not, so plan for movement. Review the payment history example in your lender’s disclosures before you sign.

Where the General Rule Breaks

Several situations break the usual pattern, so check them before you chase a lender.

The line is too small to open. The minimum line is $25,000. A modest deck may not justify a line at all, and a smaller loan or cash savings may fit better.

The property is held in an LLC. Only you or an inter vivos revocable living trust can hold title. LLCs, corporations, partnerships, and irrevocable, blind or land trusts cannot. A property already deeded to an LLC needs a vesting change before a line can be placed, or a different tool such as a DSCR cash-out, subject to lender program eligibility.

The property type is not eligible. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use and agricultural-zoned properties are not offered. Single-family homes, 2-4 units, PUDs, townhomes and condominiums, including non-warrantable condos, are eligible. Modular homes are eligible on the 5-year-draw program only. A 2-4 unit property needs a 640 minimum on that program.

The score is below 640. Sub-640 profiles are limited to single-family residences with a clean 12-month housing history on the 5-year-draw program. In practice that restriction reaches primary residences only.

You own many financed properties. A borrower can hold only three lines. Combined exposure caps at $2,000,000 on the 3-year-draw program and $750,000 on the 5-year-draw program. A borrower with more than 15 financed properties is not eligible.

The home was recently listed. In some states, a property listed for sale within the past 60 days is ineligible.

You are an investor wondering about DSCR. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. A home equity line is a different product, and it follows personal income, credit and DTI. If you hold a DSCR first loan, a line in second lien position can leave it untouched. The complete DSCR loans guide explains how that first loan works.

How Does a Deck Line Compare with Other Options?

Each option trades documentation, collateral and flexibility differently.

A cash-out refinance resets your first mortgage, which matters if your current loan is one you want to keep. On a standard rental, DSCR cash-out refinances top out around 75% LTV across most of the network, with about 6 months of seasoning as the common expectation. A short-term rental caps lower, at about 70% on cash-out. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.

What Does a Deck Add to Value?

A deck may support a higher appraised value, depending on comps and underwriter review. Do not count on it. Lines at or below $500,000 usually use an automated valuation, which will not see work you have not done. The line is sized on today’s value, not the finished project.

Tax treatment can depend on how the funds are used and how the property is held; borrowers should keep clear records and speak with a qualified tax professional before relying on any deduction.

Key Terms Defined

CLTV (combined loan-to-value): Your first mortgage balance plus the full line limit, divided by the home’s value.

Draw period: The stretch when you can borrow from the line, usually with interest-only payments on these programs.

Repayment period: The stretch after the draw ends, when you pay principal and interest and can no longer borrow.

Non-QM: A loan outside standard agency guidelines, often used when documentation is not a W-2.

Expense factor: The share of business deposits an underwriter assumes goes to costs, which lowers qualifying income.

Lien position: Whether the line sits first or second behind your existing mortgage.

What Does the Process Look Like in Practice?

1. Get a contractor quote and add a modest contingency. 2. Gather your statements, mortgage statement and ID. 3. Check your estimated CLTV, counting the full line limit. 4. Have a broker match the file to a program. 5. Complete valuation and underwriting. 6. Close, then draw at closing to fund the deposit and early work. 7. Draw later only if the program allows it, mindful of the $1,000 minimum on the 5-year-draw program.

Before you submit, avoid large unexplained deposits and keep business and personal funds in separate accounts. Do not move money between accounts just before applying.
