The Quick Read: A home equity line on the home you already own raises a down payment equal to your home’s value times the lender’s combined-loan ceiling, minus what you already owe, and then credit, debt-to-income, line-size caps, and the cash you hold back for closing costs and reserves trim that number. The line is a separate loan from the purchase loan. Each one has to be approved on its own terms.
- The ceiling depends on occupancy: up to 90% combined loan-to-value on a primary residence, but only at a 720+ credit profile and up to $500,000. An investment-property line tops out at 70%.
- A line equal to 25% of your home’s value can fund a 20% down payment on a purchase up to 1.25 times that value.
- The line must be open and funded before you go under contract.
- The HELOC payment sits outside the DSCR ratio, but it still comes out of your real cash flow.
- Whether the purchase lender accepts borrowed down payment funds depends on the program, so ask before you draw. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
What Is a HELOC Bridge, Exactly?
A HELOC bridge is a home equity line of credit on a property you already own, drawn to fund the down payment on the next one. The line bridges the gap between your equity today and the cash you need at closing. You keep your existing first mortgage in place, and the line sits behind it or beside 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.
It is not the same thing as a traditional bridge loan. A traditional bridge loan is a short-term loan built to be repaid when a specific property sells. A HELOC is a revolving line you can keep after the purchase. It does not need a sale to repay it, though a sale is one way to retire it.
The line does not buy the property. It only supplies cash. A separate loan, usually a DSCR loan on a rental, closes the purchase. DSCR stands for debt service coverage ratio, which compares a property’s monthly rent to its monthly housing payment. Because DSCR loans are business-purpose investor loans, they are reviewed differently from a standard owner-occupied mortgage. Both approvals can fail independently.
What Down Payment a HELOC Bridge Raises: The Sizing Math
The formula has three steps. Take your home’s value, multiply by the lender’s combined loan-to-value (CLTV) ceiling, then subtract everything already owed against the home. Combined loan-to-value is your first mortgage balance plus the new line, divided by the home’s value. What is left is the most the line can be.
You can run this in percentages without any dollar figures. Say you owe 50% of your home’s value on a primary residence, and your credit profile qualifies for a 75% CLTV ceiling. That leaves line room equal to 25% of the home’s value. Say a 20% down payment is what the purchase needs. That 25% line funds a purchase priced at up to 1.25 times your current home’s value.
| Scenario | Balance owed | CLTV ceiling | Line room | Purchase funded at 20% down |
|---|---|---|---|---|
| Primary, 700+ credit | 50% of value | 75% | 25% of value | Up to 1.25x home value |
| Primary, 700+ credit | 50% of value | 85% | 35% of value | Up to 1.75x home value |
| Investment, 700+ credit | 40% of value | 70% | 30% of value | Up to 1.5x home value |
These are modeled assumptions, not market data. Your real number is smaller, because you should hold back some of the line for closing costs and reserves. Opening a larger line than you need also costs you. Across our wholesale network, at least 75% of a line is drawn at closing, and pricing floats during both the interest-only period and the repayment period. A standard line charges you only on what you borrow. A line with a required opening draw does not work that way, so right-size it.
The ceilings by occupancy
The ceiling you can use depends on how the home you are borrowing against is occupied. These are typical ranges from select wholesale partners, subject to lender guidelines and full file review.
| Occupancy | Credit tier | Max CLTV | Max line |
|---|---|---|---|
| Primary residence | 720+ | 90% | $500,000 |
| Primary residence | 700+ | 85% | $500,000 |
| Primary residence | 640+ | 80% | $500,000 |
| Second home | 720+ | 90% | $500,000 |
| Investment property | 700+ | 70% | $500,000 |
A few more details matter here:
- Primary residence at 75%: a primary line can reach $750,000, but at 75% CLTV and a 700+ credit profile. A line above $500,000 is for primary residences only and requires a full appraisal.
- Investment minimum credit: an investment-property line requires at least a 700 credit score. There is no tier above 70% CLTV on an investment line.
- Primary minimum credit: a primary line can go as low as a 600 score, but at much lower CLTV and line size.
- State rules: a few states add their own caps, and Lendmire arranges HELOCs in 16 full-service states, a narrower footprint than its DSCR lending. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
Other market lenders may advertise higher CLTV figures. Those describe the broader market and not this network.
What Shrinks Your Number?
Five things pull the line below the formula result:
1. Valuation. Lines at the lower end of the size range ordinarily use an automated valuation, though a higher CLTV may call for a second look. A lower value shrinks the ceiling directly.
2. Existing liens. Every dollar you owe on the first mortgage comes straight off the top.
3. Credit. Your tier sets the CLTV ceiling. A 640 score and a 720 score face very different caps.
4. Debt-to-income. Maximum debt-to-income limits apply, and they are tighter for lower credit profiles. Lenders review your file on the interest-only payment on the maximum draw, which is stricter than what you plan to borrow.
5. Program caps. The line size cap and the three-line exposure limit both apply. Limits on the number of financed properties also apply, so confirm your portfolio count against current program guidelines.
Property type matters too. Single-family, 2-4 unit, PUD, townhome, and condo properties are eligible. Manufactured homes, co-ops, condotels, log homes, and agricultural or commercial zoning are not offered.
How Does the Purchase Lender Treat the Borrowed Money?
This is the question most homeowners skip. The DSCR lender decides whether borrowed funds count toward your down payment, and programs differ. Across our wholesale network, some accept documented line proceeds, some limit the borrowed share, and a few want a portion of the down payment in your own seasoned cash. Seasoning means the money has sat in your account for a set period. We cannot tell you one rule applies everywhere.
Expect the lender to trace the money. That means the HELOC closing papers, the draw confirmation, the bank statements showing the deposit, and the transfer into escrow. A clean paper trail matters more than the source.
Down payment and reserves are also separate tests. Reserves are the months of housing payments you keep in the bank after closing, commonly around six months of PITIA on a DSCR file. PITIA means principal, interest, taxes, insurance, and association dues. Borrowed funds may count toward the down payment and still not count toward reserves. Check this before you draw.
Most purchase files land at 75% to 80% LTV, meaning 20% to 25% down, and select high-leverage programs reach 85% LTV with roughly a 700+ score. If a HELOC funds the entire down payment, you are effectively financing close to the whole purchase price. Some programs reject that structure. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
Does the HELOC Payment Count in the DSCR?
Generally no. DSCR divides monthly rent by the property’s PITIA, so the HELOC payment sits outside the ratio. A conventional loan runs a debt-to-income test that would count the new line. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines.
Here is the catch. Your HELOC payment is still real. Two payments now lean on the same rent check. A clean coverage number can sit next to thin actual cash flow, because repairs, vacancy, management, utilities, and capital expenses sit outside the calculation too. Clearing 1.00 is not the same as making money.
A bigger down payment helps the ratio from the other side. It shrinks the new loan, which lowers the payment and can lift coverage. You are moving cost off the property and onto your personal budget. That trade is fine when you plan it. It hurts when you ignore it.
On coverage floors, 1.00 is where many select programs start. A separate select-lender path takes coverage below 1.00 with leverage and terms adjusted. Stronger ratios generally open better pricing and leverage.
Run the combined picture before you draw. Take the DSCR on the new rental, then add the interest-only payment on the line, then compare both to what the rent and your other income can carry. Yahoo Finance notes that this approach works best where debt-to-income is not already stretched, and it is a poor fit for tight budgets.
The Order of Operations
1. Check your title. A HELOC requires title in your own name or a revocable living trust. LLCs, corporations, and partnerships cannot hold title on the line. Many investors close the DSCR purchase inside an LLC, subject to lender program eligibility, but the home you borrow against must stay in your name. A property already deeded to an LLC needs a vesting change or a DSCR cash-out refinance instead.
2. Size the line. Use the percentage math above and subtract a cushion for closing costs and reserves.
3. Open the line before you shop. The line must be open and funded before you go under contract. A homeowner with steady income, solid credit, and real equity can usually get one. Someone short on any of those three usually cannot.
4. Draw and park the funds. Move the money into your bank account and leave it there, so the paper trail is clean.
5. Confirm the purchase program’s rule on borrowed funds. Do this before you draw, not after.
6. Run the DSCR file. Rent, PITIA, credit, reserves, and property type all get reviewed.
7. Close the purchase and plan the line’s payoff. Decide now whether you keep the line or retire it from a refinance, a sale, or cash flow.
Do not wait to list the home. In several states, a property listed for sale, or listed within the past 60 days, is ineligible for the line. If you are thinking of selling your current home, open the line first.
HELOC Bridge or Something Else?
| Option | Best for | Main catch |
|---|---|---|
| HELOC on current home | Keeping the home and first mortgage | Two payments, home is collateral |
| DSCR cash-out on a rental | Equity locked in a rental you own | Cash-out tops out near 75% LTV |
| Traditional bridge loan | Buying before a pending sale | Built to be repaid at a sale |
| Sell first | No added debt | You lose the property and its income |
Cash-out on a rental is the cleanest alternative when equity sits in a property held by an LLC. Our complete DSCR loans guide covers how those files work.
Where the General Rule Breaks
The lender can freeze or shrink the line. The CFPB says a lender may stop additional credit if your home’s value drops significantly or your financial circumstances change. An open but unfunded line is not guaranteed cash. Draw before you go under contract.
The home is collateral. The same CFPB page says that if you fall behind, you could lose your home. You now have two properties pledged: the home backs the line, and the rental backs the new loan. Trouble on either puts the home at risk.
The draw period ends. The CFPB notes a draw period could last 10 years, for example, and then a repayment period begins. On our wholesale programs, a primary or second-home line comes in a 3-year draw with 17-year repayment, or a 5-year draw with 25-year repayment. An investment line runs the 5-year structure only. The interest-only period is cheap to carry and easy to mistake for permanent.
Credit history can block the whole file. A bankruptcy needs 4 years of seasoning from discharge or dismissal. Foreclosure-family history splits by program on primary residences and second homes. Housing-history standards across all financed properties also apply.
Serial HELOC down payments hit a ceiling. A borrower is limited to three lines. Even before that, every line is another payment. Portfolio growth this way is bounded by your combined payments, not by DSCR.
A practitioner note: files that go sideways usually fail on sequencing, not math. The borrower draws late, or lists the home too early, or moves the money through three accounts. The strongest files clear both tests: enough equity and enough rental coverage.
Key Terms Defined
HELOC: a home equity line of credit, a revolving loan secured by the equity in a home you already own.
CLTV (combined loan-to-value): your first mortgage balance plus the new line, divided by the home’s value.
Draw period: the stretch when you can borrow from the line, usually paying interest only before repayment begins.
DSCR: debt service coverage ratio, the property’s monthly rent divided by its monthly PITIA.
PITIA: principal, interest, taxes, insurance, and association dues, the full monthly housing payment.
Seasoning (of funds): how long money must sit in your account before a lender treats it as yours.
Frequently Asked Questions
Can the line cover my entire down payment?
It can on the equity side, if the CLTV math and your credit allow it. The harder question is whether the purchase program accepts a fully borrowed down payment. Some programs want a portion in your own seasoned cash, so ask before you draw.
Can I use a HELOC on a rental I own?
Yes, but investment-property lines are tighter. The network ceiling is 70% CLTV, the minimum credit score is 700, and the line caps at $500,000. The line also needs title in your name or a revocable trust, not an LLC.
Does the HELOC payment lower my DSCR?
Generally not, because DSCR compares rent to the new property’s PITIA only. The payment still reduces your real cash flow, so check both numbers. 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.
What if my home is already listed for sale?
In several states a property listed for sale, or listed within the past 60 days, is ineligible for the line. If a sale may be on your timeline, open the line first. A traditional bridge loan may fit better when a sale is already underway.
Do I need to draw the full line?
At least 75% of the line is drawn at closing on the wholesale programs we place files with. Size the line to the need, since pricing floats and you pay on what you draw.
What to Do Next
Start with your equity, not the purchase price. Work out the line your home can support at your credit tier. Subtract the cash you will hold back. Then see what purchase price and down payment percentage that supports. For a primary residence the leverage you reach is higher, but the same home held as a rental caps at 70%. A calculator can give an illustrative estimate of that math, but it is not a quote.
