The Quick Read: The savings come from the gap between what your old debts cost and what the line costs, applied to the balance you retire, minus fees and the interest on any borrowed money you do not need, and the bank statement part changes only how you qualify, not the math. There is no fixed savings number, because the result depends on your actual debts and your actual line. The sections below give the formula, a worked structure, and the places where the savings shrink or disappear.
- The formula: annual interest saved is roughly the balance retired times the gap between old blended cost and the line’s cost, less fees and idle-draw interest.
- The best targets: high-cost revolving balances such as cards and business cards gain the most. Low-cost secured debt can lose money when it rolls into a floating line.
- The network quirk: at least 75% of the line is drawn at closing, so an oversized line can quietly erase the savings.
- The pricing risk: pricing floats for the life of the line and never converts to fixed, so a wide gap at closing can narrow later.
- The investment-property ceiling: an investment line tops out at 70% CLTV and $500,000, and the property must be titled to you personally or to a revocable trust.
What Actually Creates the Saving?
The saving is a spread, not a product feature. You pay off debts that cost more than the line, and the difference in interest cost, multiplied by the balance moved, is your gross saving. Everything else here either subtracts from that number or protects it.
How large a line the equity supports.
An equity line is sized by combined loan-to-value, occupancy, and credit — not by rental coverage. Switch the occupancy or the credit band and the ceiling moves with it.
Investment-property lines require a 700 minimum credit score; second-home lines start at a 640 minimum and primary-residence lines at 600, and the combined-LTV ceiling steps down as the credit band drops on primary-residence and second-home lines and holds on investment-property lines; the line cap steps down on primary-residence lines and holds at every tier on investment-property and second-home lines.
A debt-to-income ratio above 45% requires 680+ credit. Profiles under 640 are limited to single-family homes. At least 75% of the approved line is drawn at closing. Ceilings, floors, and caps update from Lendmire’s centralized guideline source.
Line estimate
Illustrative estimate only — not a quote, Loan Estimate, approval, or commitment to lend. The rate is an editable assumption; equity-line pricing is variable through both the draw and repayment periods and never converts to fixed. Occupancy and credit drive the ceiling together: an investment property tops out at 70% combined LTV (minimum credit 700, line cap $500,000); a second home tops out at 90% combined LTV (minimum credit 640, line cap $500,000), with the ceiling stepping down as the credit band drops (the cap holds at every tier); a primary residence tops out at 90% combined LTV (minimum credit 600), and its $750,000 maximum line is available only at 75% combined LTV or below with a 700-or-better credit profile (720 on the longer-runway program) and a full appraisal. Lines above $500,000 require a full appraisal. Credit, debt-to-income, property type, and full underwriting review all affect the final line.
Here is the formula as a broker would sketch it on a napkin:
1. Take the balance you retire.
2. Multiply it by the gap between your old blended cost and the line’s cost.
3. Subtract closing and valuation costs, plus any fees.
4. Subtract the interest on any part of the line you draw but do not need.
5. Adjust for pricing moving over time, because the line floats.
What does the bank statement part change? It changes qualification. A bank statement HELOC is a revolving line of credit, secured by the property, that verifies income from 12 or 24 months of deposits instead of traditional personal-income documentation. That helps a landlord or business owner whose returns look thin after depreciation and write-offs.
It does not change what the line costs. A borrower approved on deposits pays the same kind of floating price as any other borrower. The loan also still gets a credit review, a debt-to-income test, an equity test, and a property review.
Key Terms Defined
CLTV (combined loan-to-value): Your existing mortgage balance plus the new line, divided by the property’s value.
Draw period: The stretch when you can borrow from the line and payments are interest-only.
Repayment period: The stretch after the draw ends, when the balance is paid down through full amortizing payments.
DTI (debt-to-income): Your monthly debts divided by your qualifying monthly income. On these lines it is tested on the interest-only payment at the maximum draw.
Blended cost: The average cost of all the debts you plan to pay off, weighted by balance.
Second lien: A loan that sits behind your first mortgage and leaves that first mortgage untouched.
DSCR cash-out refinance: A new investor loan that replaces the first mortgage and pays you cash. It qualifies primarily on property-level rental income covering the payment, subject to lender guidelines.
How Does Underwriting Treat a Consolidation Line, Step by Step?
Underwriting treats a consolidation line like any other line: it tests income, then equity, then the payment at the full line. The sequence below is how most files move through the wholesale network that Lendmire places bank statement HELOC files with.
Step 1: Income comes from deposits. The reviewer works from 12 or 24 months of personal or business statements. Transfers between your own accounts and one-time deposits come out. What remains is averaged, and business deposits are usually reduced further, sometimes through an expense factor. Exact treatment varies by lender.
Step 2: Equity sets the ceiling. The lender takes a percentage of the property’s value, subtracts what you owe on the first mortgage, and the remainder is the potential line. On an investment property, the network ceiling is 70% CLTV, with a 700 minimum credit score and a maximum line of $500,000.
Step 3: Valuation. Lines at or below $500,000 ordinarily use an automated valuation instead of a traditional appraisal. That keeps one cost out of your savings math. A higher CLTV may call for a second valuation, and you may request a full appraisal in any case.
Step 4: The payment is tested at the full line. This is the step that surprises consolidation borrowers. The DTI cap is 50%, and the lender calculates it on the interest-only payment at the maximum draw. Planning to use only part of the line does not help here. If your debts and the full-line payment together push DTI too high, the file fails even though you never meant to borrow the whole amount.
Step 5: Draw and pay off creditors. Interest accrues only on what you have borrowed, as the FTC’s explanation of home equity lines puts it for standard lines. On this network, though, at least 75% of the line is drawn at closing. Treat that as a sizing rule, not a footnote.
Step 6: Draw period, then repayment. During the draw, payments are interest-only, so the principal does not fall unless you pay it down yourself. When the repayment period starts, payments include principal and step up.
What Does the 75% Draw Rule Do to Your Savings?
It means the line should be sized to the debt, not to the maximum the lender will offer. If you draw at least 75% of the line at closing, every dollar of that draw costs interest whether or not it went to a creditor.
Picture a borrower with card and business-card balances that add up to a small fraction of the approved line. The creditors get paid, and the rest of the required draw sits in an account earning far less than the line costs. That idle money is a negative in the formula above.
The fix is simple. Ask for a line close to the size of the debts you are retiring, plus a modest cushion. A smaller line also lowers the full-line payment that the DTI test uses, so it protects both the savings and the approval.
Payment Saving Versus Total-Cost Saving
A lower monthly outflow is not the same as a lower total cost. A line can cut your monthly payments sharply and still cost more over the full life of the debt. The table shows how the same consolidation looks under three behaviors, with no dollar figures because your numbers will differ.
| Strategy | Monthly outflow | Total interest cost |
|---|---|---|
| Interest-only, never pay principal | Lowest | Highest over time |
| Interest-only, then repayment period | Low, then a step up | Middle |
| Pay principal down on your own | Higher | Lowest |
Interest-only draws help portfolio liquidity, which is a real benefit for a landlord. They also leave the original debt intact, only moved. Cash-flow relief is useful, but it is a different thing from savings.
The draw and repayment structures matter here. Two structures exist on primary residences and second homes. One has a 3-year interest-only draw followed by 17 years of full amortization. The other has a 5-year draw followed by 25 years of full amortization, and this article calls it the longer-runway structure. Investment lines run only the 5-year draw and 25-year repayment structure. A longer repayment window lowers each payment, but it also stretches the interest out.
Where Do the Savings Shrink?
Savings shrink when the line’s price rises, when costs pile up, when the payoff stretches out, or when the old balances refill. Each of these has a direct effect on the formula.
| Erosion factor | What it does to the saving |
|---|---|
| Floating pricing moves up | Narrows the gap on the whole balance |
| Fees and valuation costs | Subtracted once, up front |
| Idle draw (75% rule) | Adds interest on unneeded money |
| Longer payoff window | Lowers payment, raises total interest |
| Cards refill | Leaves you with the line plus new debt |
| Counted income below earned income | Shrinks the line and the debt you can move |
Floating pricing. A HELOC’s pricing has two parts: an index and a margin the lender adds. When the index moves, your payment moves with it. The CFPB’s HELOC explainer notes that some lenders let you convert part of a balance to a fixed price. The lines Lendmire places across its wholesale network do not offer that, because pricing floats across both the draw and the repayment period. Stress-test the saving by asking what happens if your line costs noticeably more than it does at closing. If the gap on your highest-cost debts survives that test, the saving is sturdy.
Refilling the cards. A consolidation can fail this way. Cards drop to zero, spending creeps back, and a year later you owe the line and the cards. The saving is gone, and the debt now sits on your property.
Counted income below earned income. If write-offs or an expense factor reduce the income that counts, the DTI test gets tighter and the line may come in smaller than the debt you wanted to move. That is a sizing problem, and it shows up before the savings math does.
Which Debts Are Worth Moving?
Move the debts that cost the most and carry no special protection. Leave alone the ones that are cheap, secured, or protected. Bankrate’s consolidation guide puts credit cards firmly in the consolidate category. It also notes that home equity borrowing generally costs well below typical card pricing.
| Debt type | Fit | Why |
|---|---|---|
| Credit cards | Strong | Highest-cost revolving balances |
| Business cards | Strong | Same logic, and they often carry high costs |
| Personal loans | Think twice | Depends on the gap and the remaining term |
| Auto loans | Leave alone | Often cheap, and already secured |
| Low-cost first mortgage | Leave alone | A second-lien line keeps it in place |
| Public student loans | Leave alone | Rolling them into private debt can forfeit protections |
The first mortgage deserves a second look. A bank statement line is a standalone line that can sit in first or second lien position. In second position, it leaves your current mortgage untouched. A line in first position sits ahead of everything else, so it fits a property with no mortgage on it. If your mortgage carries cheap pricing, keeping it in place under a second-lien line can be worth more than any consolidation spread. A cash-out refinance would replace it.
Business-purpose borrowing can also draw questions. Expect the lender to ask what the draw is for, and keep your records clean.
Bank Statement HELOC, DSCR Cash-Out, or an Unsecured Loan?
The right tool depends on how you hold title, how many properties you finance, and whether you want fixed or floating pricing. Here is how the main options trade off.
| Factor | Bank statement HELOC | DSCR cash-out refinance | Unsecured consolidation loan |
|---|---|---|---|
| Reviewed on | Deposits plus DTI | Property rent vs. payment | Borrower credit and income |
| Title | Individual or revocable trust | LLC may be allowed* | No collateral |
| First mortgage | Stays in place under a second-lien line | Replaced | Not affected |
| Pricing | Floats, never fixed | Fixed or adjustable options | Usually fixed |
| Leverage cap | 70% CLTV (investment) | Around 75% LTV on a standard rental | Not property-based |
*LLC-titled properties are subject to lender program eligibility.
A DSCR cash-out refinance on a standard rental tops out around 75% LTV across most of the network, and about 6 months of seasoning is the common expectation. The coverage ratio is monthly rent divided by the full monthly payment, meaning principal, interest, taxes, insurance, and any HOA dues. Many select programs start at 1.00. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
Clearing 1.00 does not mean positive cash flow. Repairs, vacancy, management, utilities, and capital expenses all sit outside the calculation. For a deeper look at how that product works, see Lendmire’s complete DSCR loans guide.
DSCR files also tend to suit larger portfolios. A bank statement line tests DTI at the borrower level, so many financed properties can block it even when every rent is strong. A borrower with more than 15 financed properties is not eligible at all. DSCR looks at each property’s own cash flow instead.
Where Does the General Rule Break?
The “move the expensive debt, save the spread” rule breaks in a handful of named situations.
- LLC-held rentals. Only an individual 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 or a DSCR cash-out instead.
- Ineligible property types. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not offered. Single-family, 2-4 units, PUDs, townhomes, and condos, including non-warrantable condos, are eligible.
- Owner-occupied lines are a different table. The 70% CLTV ceiling applies to investment property only. On primary residences and second homes the ceiling reaches 90% CLTV, and only at a 720-or-better credit profile. A line above $500,000 is primary-residence only, requires a credit profile of 700 or better (720 on the longer-runway structure), caps at 75% CLTV, and requires a full appraisal.
- Line exposure. A borrower is limited to three lines in total.
- Line freezes. HELOCs generally let the lender freeze or reduce a line if the property’s value falls or your finances worsen. A plan that assumes continued access to the line can break when you need it most.
For readers whose situation is a self-employed owner clearing debts, Lendmire’s piece How Much a Bank Statement HELOC Saves a Self-Employed Owner on Debt walks through that case. For business balances in particular, see Lendmire’s breakdown of monthly savings on business debt.
Can Your Income Carry the Line?
Your income carries the line if your deposit-based income, after reductions, supports the full-line interest-only payment alongside your other debts at a DTI of 50% or lower. Credit tiers tighten that: the cap drops to 45% for profiles from 600 to 679, and a ratio above 45% requires at least 680.
Run this check before applying:
1. Add up the debts you want to retire and your existing monthly obligations.
2. Estimate your counted income, which will be lower than total deposits.
3. Test the payment on the whole line you would be approved for, not the amount you plan to use.
4. Check your slowest month, not your average one. Self-employed income swings, and the payment does not.
The site’s illustrative calculator can help you size a line against the debts you plan to retire. Treat it as an estimate, not a quote.
What Are the Risks, and Who Should Skip It?
The biggest risk is the collateral swap. Consolidating moves unsecured debt onto your property. A bad quarter that once hurt only your credit score can now threaten a property.
The CFPB’s HELOC booklet advises borrowing against your home only if you are confident you can keep up with payments. That advice fits this product well.
Skip the line if any of these describe you:
- Your cards tend to refill within months.
- Your income would not cover the full-line payment in a slow month.
- Your highest-cost debts are small relative to the line you would need.
- Your first mortgage is cheap and you would have to replace it.
- You hold title in an LLC and do not want to change it.
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.
A note on credit: the program uses a single-bureau score keyed to the primary wage earner, and the minimum is 600 on primary residences, 640 on second homes, and 700 on investment property. Paying off cards usually lowers your utilization, but the new line is itself a credit event. Plan around both effects.
Frequently Asked Questions
How much can I actually save by consolidating with a bank statement line?
It depends on the gap between your current blended cost and the line’s cost, the balance you retire, and what you pay in fees. Multiply the first two, then subtract the costs. Savings are largest when high-cost cards make up most of the balance and smallest when the debt is already cheap.
Does using bank statements make the line cost more?
Not by itself. Deposits change how your income is documented, not the structure of the line. Pricing on the loan reflects the line’s terms, your credit, and your leverage, and every file is underwritten individually.
Can I use only part of the line?
Not freely. At least 75% of the line is drawn at closing, and DTI is tested on the payment at the full line. Ask for a line sized close to your debts so you are not paying interest on money you do not need.
Is a DSCR cash-out refinance a better fit for rentals?
Often, for borrowers with an LLC, many financed properties, or strong rents. A DSCR file qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. The tradeoff is that it replaces your first mortgage.
Can I get this line on a property held by my LLC?
No. These lines require title in your own name or an inter vivos revocable living trust. An LLC-held property needs a vesting change first, or a DSCR cash-out refinance may fit better, subject to lender program eligibility.
