The Quick Read: A lender sizes your line by adding your first-mortgage balance to the full line limit and dividing the total by the home’s value. Bank statements prove your income but never change that equity math. Your low first-mortgage rate also adds no room, because only the loan’s balance counts. The ceiling depends on how the property is used, and it is lowest on a rental.
- On an investment property, the ceiling is 70% combined loan-to-value (CLTV), with a 700 minimum credit score and a $500,000 maximum line.
- On a primary residence or second home, the ceiling reaches 90% CLTV, and only at a 720-or-better credit profile.
- The lender counts the whole line limit toward CLTV, not just the amount you draw.
- Your first mortgage’s payment still counts in the debt-to-income review, even though its rate does not count in the leverage math.
- Every figure here is subject to lender guidelines and full file review. None of it is a commitment to lend.
Key Terms Defined
HELOC: A home equity line of credit. It is a revolving loan secured by the property, and you borrow against it in draws.
Bank statement HELOC: A line that is reviewed on documented income under the applicable program, subject to lender guidelines. The lender builds your income from 12 or 24 months of deposits instead of traditional personal-income documentation.
CLTV (combined loan-to-value): All loans secured by the property, added together, divided by the property’s value.
Second lien: A loan that sits behind your first mortgage. If the property is sold or foreclosed, the first mortgage gets paid first.
Expense factor: A discount the lender applies to business-account deposits to account for the costs of running the business.
DTI (debt-to-income): Your monthly debts divided by your monthly qualifying income.
Draw period: The early stretch when you can borrow from the line and pay interest only.
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.
Why the Lock-in Homeowner Looks at a Second Lien
Many owners hold a first mortgage well below today’s market pricing. ICE, a mortgage-data firm, says that gap is why second liens look attractive to millions of them. A line behind the first mortgage taps equity and leaves the cheap loan alone.
The catch is sizing. A Stacker analysis of the rate-lock effect puts total mortgage-holder equity near $17 trillion. It calls about $11 trillion “tappable,” meaning borrowable while leaving roughly a 25% cushion. That is a market-wide convention, not a lender ceiling. On this network an investment line stops at 70% CLTV, so the cushion there is larger.
How Combined LTV Is Calculated When You Keep Your First Mortgage
The formula has three steps. Add your first-mortgage balance and the full line limit. Divide by the home’s value. Compare the result with the ceiling for your occupancy and credit tier.
Run it backward to find your maximum line. Take the value times the ceiling, subtract every lien already on the property, and apply the dollar cap. The smallest of three limits wins:
1. Equity under the ceiling.
2. The program’s dollar cap.
3. What your debt-to-income ratio can carry.
Here is the part lock-in owners miss. Your first mortgage shrinks the line through its balance. Its terms add nothing to the CLTV formula. The first mortgage’s payment does appear later, in the DTI test.
Bank statements sit on the income side only. They never raise the ceiling. Across the programs we place files with, a self-employed borrower and a W-2 borrower face the same leverage cap on the same property.
Worked Example: What the First Mortgage Leaves You
Picture an owner of a rental who wants a line on that property. The ceiling is 70% CLTV. The table shows how the first mortgage’s share of value drives the room left. These are percentages of value, and the dollar cap can still bind first.
| First mortgage, % of value | Room under 70% | What it means |
|---|---|---|
| 40% | 30% of value | Room up to the dollar cap |
| 65% | 5% of value | A small line, if any |
| 70% or more | None | No line on this property |
Now take a primary residence at 720 or better, where the ceiling reaches 90%. A first mortgage at 60% of value leaves 30% of value. At a lower credit tier, the same owner faces a lower ceiling and less room.
Two things move the result after closing. Scheduled paydown of the first mortgage slowly adds room. A lower valuation takes room away, and the lender sets the value input, so that number drives everything.
Limits by Occupancy and Credit Tier
Ceilings on this network depend on how the property is used. Pick your row first, then your credit tier.
| Occupancy | Credit floor | Ceiling | Max line |
|---|---|---|---|
| Investment property | 700 | 70% CLTV (700+ and 720+ alike) | $500,000 |
| Second home | 640 | Up to 90% CLTV, only at 720+ | $500,000 |
| Primary residence | 600 | Up to 90% CLTV, only at 720+ | $750,000 |
Some details sit under those headline numbers.
- Investment property: Credit above 700 buys nothing extra. A 720 score and a 700 score reach the same 70% ceiling. Below 700, no investment line is offered.
- Second home: The ceiling steps down with credit. It runs 85% at 700 and 680, 80% at 660, and 75% at 640. The 90% figure belongs to 720 and above.
- Primary residence: The ceiling steps up with credit, reaching 90% at 720 and above. At 700 or better, a line up to $750,000 caps at 75% CLTV. A 90% ceiling applies to lines up to $500,000.
Lines above $500,000 are primary-residence only. They cap at 75% CLTV and require a full appraisal. The credit requirement is 700 or better (720 on the longer-runway program, the one with the 5-year draw).
Market surveys sometimes report higher CLTV figures on equity lines. Those describe the broader market. On this network, an investment line stops at 70%.
What the Lender Does With Your Bank Statements
Equity and income are separate tests. The statements feed only the income test.
- Collect. The lender uses 12 or 24 months of deposits from business accounts, personal accounts, or both.
- Strip. Transfers and loan proceeds come out, because they are not earnings.
- Discount. Business-account deposits take an expense factor. The lender sets it from the business type and profit-and-loss picture. You do not choose it. Personal-account programs generally skip this step.
- Average. Eligible deposits are divided by the number of months, then reduced by whatever the expense factor leaves.
- Check the trend. Falling deposits can trigger a letter of explanation or a shorter lookback.
The resulting income goes into the DTI test. Maximum DTI is 50%. It drops to 45% for credit profiles from 600 to 679, and anything above 45% requires a 680 score or better. The lender tests the interest-only payment calculated on the maximum draw, not the amount you plan to use. Exact terms depend on lender and investor guidelines, credit profile, reserves, and property review.
So three limits compete: equity, the dollar cap, and DTI. A borrower with thick equity and thin deposits gets stopped by DTI. A borrower with strong deposits and a heavy first mortgage gets stopped by equity.
Why the Full Line Counts, Not Just What You Draw
Lenders count the full line limit toward CLTV. A line you plan to draw only partly still uses its full share of the ceiling. This surprises owners who want a large line as a safety net and a small draw.
The structure also pushes the other direction. At least 75% of the line is drawn at closing. Most of the line is a real loan on day one.
The line is a standalone loan in first or second lien position. Pricing floats through the draw and repayment periods and never converts to fixed. On primary residences and second homes, two draw structures exist:
- A 3-year interest-only draw with a 17-year repayment.
- A 5-year interest-only draw with a 25-year repayment.
Investment lines use the 5-year draw and 25-year repayment only. The CFPB’s HELOC booklet lists variable repayment as a disadvantage of these lines. Your payment can move after closing.
Where the General Rule Breaks
The rule is simple. Real files hit edge cases that end or reshape the line. These are the main ones.
A recently bought rental. Purchase leverage is often high enough that little or no room is left under 70%. Many owners need time and paydown before a line makes sense.
A portfolio. The ceiling applies to each rental’s own collateral. Equity in one property cannot cover a shortfall in another. A borrower can hold up to three lines, and an owner of more than 15 financed properties is not eligible.
An entity-owned rental. Title must sit with you personally or in an inter vivos revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. This is the sharpest difference from a DSCR loan. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines, and it can close in an entity, subject to lender program eligibility. A property already deeded to an LLC needs a vesting change or a DSCR cash-out instead.
Ineligible property types. These are not offered on a home equity line: manufactured homes, co-ops, condotels, log homes, and commercial, mixed-use, or agricultural-zoned property.
State overlays. New Mexico and Ohio apply a CLTV cap that depends on the credit profile. A Texas primary residence is a homestead and caps at 80% combined loan-to-value, so the higher primary tiers never apply there. Lendmire places these lines in 16 full-service states only, a narrower footprint than its DSCR lending.
A value drop after closing. The same CFPB booklet notes that lenders generally can freeze or reduce a line if the home’s value falls or your finances worsen. It also warns that renting the home out may be prohibited under the line’s terms. Read your agreement before you count on the line as a rental-funding source.

Keep the First Mortgage or Replace It?
A line behind the first mortgage and a cash-out that replaces it are different tools. They are underwritten differently.
| Factor | Bank statement HELOC | DSCR cash-out |
|---|---|---|
| Underwritten on | Your income, DTI, credit | Rent versus PITIA |
| Your first mortgage | Stays in place | Gets replaced |
| Leverage on a rental | 70% CLTV | Around 75% on a standard rental |
| Title | Individual or revocable trust | Entity allowed, subject to program terms |
| Best fit | Modest or uncertain need | Large, known sum |
PITIA is principal, interest, taxes, insurance, and association dues. On most DSCR files in the network, a cash-out refinance tops out around 75% LTV, with about 6 months of seasoning commonly expected. Seasoning is the waiting period between buying a property and refinancing it.
On coverage, 1.00 is where many select DSCR programs start. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Clearing 1.00 is not the same as positive cash flow. Repairs, vacancy, management, and capex sit outside that calculation.
The honest test has two parts. First, how large is the sum you need? A modest sum favors the line, since you keep the cheap first mortgage. A large sum favors the cash-out, because the line’s cap and ceiling may not reach it.
Second, how long will the payment float? The line’s pricing never converts to fixed. A cash-out can run a 30-year fixed structure, and extended terms and interest-only periods exist through select lenders. The complete DSCR loans guide covers those structures in full.
Most owners also ask how this compares with a rental-focused line. Lendmire’s piece Bank Statement HELOC vs Rental HELOC for a Lock-In Landlord covers that choice.
Risks and Who Should Skip
A line behind your first mortgage puts the home at risk if you stop paying. Skip it, or wait, in these situations:
- You have thin equity. If your first mortgage is near the ceiling, the room is too small to matter.
- Your deposits are falling. Lower income can fail the DTI test even with plenty of equity.
- You need a fixed payment. The line floats and never converts.
- The need is large. A big, known purchase usually outgrows the line’s dollar cap.
- The property sits in an LLC and you cannot change the vesting.
The line usually funds a down payment and part of the closing costs on the next purchase. It rarely funds the whole price. 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.
Pre-Application Checklist
Gather these before anyone runs the math:
- Your current first-mortgage statement, showing the balance.
- A realistic value estimate for the property.
- A list of every other lien on the property.
- Twelve or 24 months of bank statements for the accounts you want counted.
- A credit profile, since your score sets the tier.
- Your vesting: your name, a revocable trust, or an entity.
Frequently Asked Questions
Does the lender count my whole line or only what I borrow?
The whole line. The full limit goes into the CLTV numerator whether or not you draw it. At least 75% of the line is drawn at closing anyway, so a large line you barely need uses up ceiling you may want for something else.
Does my existing first mortgage help me qualify for more?
No. Only the first mortgage’s balance enters the CLTV formula. Its payment still counts in your DTI. A favorable first mortgage keeps your carrying cost down, but it does not buy extra leverage.
Will bank statements get me a higher CLTV than a W-2 borrower?
No. Deposits prove income and feed the DTI test. The equity ceiling depends on occupancy and credit tier, so a self-employed borrower and a wage earner face the same cap on the same property.
Can I use a line on a rental owned by my LLC?
Not as titled. The individual borrower or a revocable living trust must hold title. An LLC cannot. A vesting change may solve it, or a DSCR cash-out can work for entity-held rentals, subject to lender program eligibility.
Does a higher credit score raise my ceiling on a rental?
Not above 700. A 700 and a 720 reach the same 70% CLTV on an investment property. Score matters more on primary residences and second homes, where higher tiers unlock a higher ceiling.
