The Quick Read: Open the equity line on the home you are leaving while it is still unlisted, draw the amount the down payment and closing costs need, buy the next place, and let the sale proceeds pay the line off when the old home closes. Timing decides the whole plan, because many lenders will not open a line once a home is on the market.
- Open before you list. In a few states a listed home, or one listed in the past 60 days, is ineligible outright. Elsewhere it depends on the lender.
- Size the line to the plan. On Lendmire’s wholesale programs, at least 75% of the line is drawn at closing. An oversized line means paying for money you do not need.
- The line does not move with you. It is a lien on the old home and is repaid from the sale.
- The new loan decides how the line is judged. A DSCR loan reads the new property’s rent against its payment. A conventional loan counts your whole debt load.
How Does the HELOC Bridge Actually Work?
A HELOC bridge borrows against the equity in the home you own now to fund the purchase of the next one. You carry both properties until the first one sells. Then the sale pays off the line.
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.
Equity is the home’s value minus what you owe on the mortgage. A home equity line of credit, or HELOC, is a revolving credit line secured by that equity. You draw cash, make payments, and during the draw period you can often borrow again.
The sequence is simple:
1. Open the line on the current home.
2. Draw what the next purchase needs.
3. Put that money toward the down payment and closing costs on the next property.
4. Carry both homes while the old one is for sale.
5. At the sale closing, proceeds pay the first mortgage, then the HELOC. Whatever remains goes to you.
A HELOC is not a true bridge loan. A bridge loan is short-term financing built for the gap between buying and selling. A HELOC is a general-purpose line that happens to work for that gap when the timing is right.
The next home also has to be financed. If you will live in it, that is an ordinary owner-occupied mortgage, and your income and debts drive the decision. If it is a rental, a DSCR loan may fit. DSCR loans are designed for non-owner-occupied investment properties. Because they are business-purpose investor loans, they are reviewed differently from a standard owner-occupied mortgage.
Open the Line Before You List
The line should be open, and ideally drawn, before the home goes on the market. Many lenders treat a listed home as a reason to decline a new line or freeze an existing one. Some of that is guideline, not a judgment about your credit.
The wholesale programs Lendmire places home equity lines with are explicit about it. In a handful of states, a property that is listed for sale, or was listed in the past 60 days, is ineligible. In other states it comes down to the individual lender. Availability matters too. Lendmire places these lines in 16 full-service states, a narrower footprint than its DSCR lending.
Here is the order of operations that works:
1. Decide the next-home plan and the likely down payment before you call a listing agent.
2. Apply for the line while the home is still unlisted.
3. Draw what the plan needs once the line is open.
4. List the old home only after the money is in hand.
Reverse that order and you may find the door shut right when you need it. The same goes for an undrawn line left open “just in case”. A line you have not drawn is permission to borrow, not committed money, and a lender can freeze it.
How Much Can You Borrow, and How Much Should You?
Size the line from the equity you have and the cash the purchase needs, with a cushion. Lenders limit the combined balance of your first mortgage and the new line, called combined loan-to-value, or CLTV.
On Lendmire’s network, the ceilings depend on how the property is used:
- Primary residence: the ceiling reaches 90% CLTV, but only at a 720-or-better credit profile and only on lines up to $500,000. At 700 and above, a line up to $750,000 tops out at 75% CLTV. Lower credit tiers step down from there, and the program minimum is a 600 score.
- Second home: the ceiling reaches 90% CLTV at 720 and above, on lines up to $500,000. The minimum score is 640.
- Investment property: the ceiling is 70% CLTV, with a 700 minimum score and a $500,000 maximum line.
Market surveys such as NerdWallet’s look at HELOCs on investment property report that investment-property lines come from fewer lenders and carry stricter terms. They cite typical credit scores of 720 or higher and maximum loan-to-value up to 80% across the broader market. On Lendmire’s network the investment-property figure is 70% CLTV, with a 700 minimum.
Run a modeled example. Say your home is worth 100 units and your first mortgage is 50 units. At a 75% CLTV ceiling, total debt on the home can reach 75 units. That leaves room for a line of up to 25 units. Selling costs will come out of the proceeds later, so do not borrow to the ceiling just because it is there.
Two structural rules matter for a bridge:
- Most of the line is drawn at closing. At least 75% of the line funds on day one. Size it close to what you need.
- Payments float. Both draw structures stay variable and never convert to fixed.
On a primary residence, the draw structure is either a 3-year interest-only draw followed by a 17-year repayment period, or a 5-year draw followed by 25 years of repayment. Investment lines run only the 5-year/25-year structure. A bridge ends in months, so the draw period is rarely the constraint. The interest-only payment is. If the home sits, you keep paying on the full drawn balance.
Qualification looks at your debt load. The maximum DTI is 50%, or 45% for credit profiles from 600 to 679. A ratio above 45% requires at least a 680 score. Lenders calculate the payment on the maximum draw, so expect your debts to look heavier on paper than the amount you plan to borrow.
For lines up to $500,000, the valuation is ordinarily automated, with no traditional appraisal. Higher CLTV may require a second valuation, and you can always request a full appraisal. Lines above $500,000 are primary-residence only, top out at 75% CLTV, and require a full appraisal.
The CFPB’s plain-language HELOC explainer says a draw period could last 10 years, for example. It also warns that falling behind on payments could cost you the home. Both points matter when the “temporary” bridge stretches longer than planned.
Which Loan Buys the Next Property?
The loan on the new property decides how your HELOC is treated. This is the fork where plans succeed or stall.
If the next property is a rental and a DSCR loan buys it, the lender qualifies the file primarily on property-level rental income covering the payment, subject to lender guidelines. DSCR means debt service coverage ratio: monthly rent divided by the monthly payment covering principal, interest, taxes, insurance, and any HOA dues. Your personal DTI is not the main test. That is why investors who are tapped out on conventional debt-to-income often use a HELOC on their primary home for the down payment. Lendmire’s complete DSCR loans guide covers the full program structure.
Here is what DSCR files typically look like across the network:
- Purchase leverage: most files land at 75%-80% LTV on an investment-property purchase, meaning 20%-25% down. Select programs reach 85% LTV on a purchase with roughly a 700+ score.
- Coverage: 1.00x is where many select programs start. A separate select-lender path takes coverage below 1.00x, with leverage and terms adjusted. Stronger ratios open better leverage and pricing.
- Credit: a 620 floor exists in parts of the network, most programs want around 660, and 700+ unlocks the strongest leverage tiers.
- Reserves: commonly around 6 months of PITIA (principal, interest, taxes, insurance, and association dues). That varies by lender, leverage, loan size, and transaction type.
Clearing 1.00x is not the same as positive cash flow. DSCR compares rent to PITIA only. Repairs, vacancy, management, utilities, and capital expenses sit outside the calculation. Your HELOC payment is also outside the ratio, but it is a real bill you pay from your own pocket.
Whether HELOC money counts as your down payment varies by DSCR program. Some programs want part of the down payment from your own seasoned cash. Ask before you sign a purchase contract, not after. A larger down payment lowers the payment and can lift the coverage ratio. It never erases leverage caps, credit floors, reserve rules, or property eligibility. The strongest files have enough equity and enough rental coverage.
If the next property is your own residence, the new lender counts the old mortgage, the HELOC payment, and the new mortgage together. That is three obligations on one DTI. It is usually the real hurdle in a conventional bridge, and it deserves a hard look before you apply.
For related reading, Lendmire’s piece Does a Bridge HELOC Hurt Your Credit Before Your Home Sells explains the credit side of this plan.
What Does the Overlap Cost to Carry?
You pay for two homes at once, and the HELOC adds a third line item. Build the budget before you draw, using these pieces:
- the old home’s mortgage, taxes, insurance, and utilities;
- interest-only payments on the drawn HELOC balance, which float;
- the new property’s payment, plus any rehab or move-in costs;
- reserves, so a slow sale does not drain your cash.
A rental that covers an interest-only payment can come up short once principal is added. Rent usually does not rise to match. Test the plan on a longer overlap than you expect, then ask whether you could carry it without panic.
A useful stress test has three questions:
1. Can you cover everything if the old home sits for twice as long as you hope?
2. Does the plan survive a price reduction on the old home?
3. If the line were frozen tomorrow, would the purchase still close?
If the third answer is no, you are leaning on money that is not yet in your account.
Sell, Pay Off, and Walk Away
At the sale closing, proceeds pay the first mortgage, then the HELOC, then selling costs, and you keep the remainder. The line is tied to the old collateral, so it ends with the sale. The CFPB’s HELOC booklet lists repayment that is often required on sale as a downside of the product.
The same booklet says lenders can generally freeze or reduce a line if the home’s value falls or your finances worsen. It also notes that renting the home out may be prohibited under the line’s terms. That matters if you hoped to keep the old place as a rental. If the sale price does not cover the mortgage, the line, and selling costs, you must bring cash or get lender approval for a short sale.
Where the Rule Breaks
The standard plan assumes a primary-residence line, an unlisted home, and a clean sale. Several situations bend it.
- The home is already listed. The listing may make the line ineligible, or the lender may decline it as policy. Try a different equity source, such as a cash-out refinance, or wait. A cash-out refinance generally carries higher closing costs than a line.
- The property sits in an LLC. On Lendmire’s network, an LLC, a corporation, a partnership, and irrevocable, blind, or land trusts cannot hold title on a HELOC. Only an individual borrower or a revocable living trust can. A property already deeded to an LLC needs a vesting change, or a DSCR cash-out refinance instead.
- You want a line on a rental you already own. The investment-property line tops out at $500,000, needs a 700 score, and has a 70% CLTV ceiling. There is no tier above it.
- The home type is unusual. Single-family, 2-4 unit, PUD, townhome, and condominium (including non-warrantable) properties can be eligible. Manufactured homes, co-ops, condotels, log homes, and commercial, mixed-use, or agricultural zoning are not offered.
- You are a larger investor. A borrower is limited to three lines, and one owning more than 15 financed properties is not eligible.
- Your credit has dings. A bankruptcy needs 4 years of seasoning from discharge or dismissal. Foreclosure history splits by program, and some decline it regardless of age.
- The DSCR lender questions the borrowed down payment. This varies by program, so confirm the source-of-funds rule before the contract.
If you plan to keep the old home as a rental instead of selling it, treat that as a different product decision. A line secured by a rental is narrower and comes from fewer lenders, per the NerdWallet piece above.
What If the Old Home Does Not Sell?
Set trigger points before you draw. The failure path has a few decision gates, and it is easier to follow a plan you made when things were calm.
1. First trigger: the price. If the home draws showings but no offers, adjust the price rather than let the interest-only balance run.
2. Second trigger: the carry. If your reserves fall below the level you set, stop adding new spending and consider a refinance or a smaller purchase.
3. Third trigger: the exit. If the home will not sell at an acceptable price, consider keeping it. Check whether the line’s terms allow renting, and look at a cash-out refinance on the old home as the way to retire the line.
4. Last resort: restructure the new purchase. Selling the new property is painful but less damaging than a missed HELOC payment on the old one.
One more caution applies to DSCR loans. Some carry prepayment penalties, which can make a quick cash-out refinance on the new rental expensive. Ask about that before you rely on it as an exit.
HELOC Versus the Other Ways to Bridge
| Tool | How it works | Main risk |
|---|---|---|
| HELOC | Revolving line on old home | Freeze; floating payment |
| Bridge loan | Short-term interim loan | Higher cost; repay at sale |
| Cash-out refinance | Replaces the first mortgage | Higher closing costs |
| Sell first, rent back | Proceeds before you buy | Housing gap; moving twice |
| Savings or sale contingency | Own cash, or offer tied to sale | Weaker offer; limited cash |
No single option wins. A HELOC is the lower-cost route when you have time, equity, and unlisted status. A bridge loan or sale contingency may fit better when the line is no longer available.
Key Terms Defined
Equity: the home’s value minus what you owe on the mortgage.
CLTV (combined loan-to-value): your first mortgage plus the new line, divided by the home’s value.
Draw period: the stretch when you can borrow from the line, often paying only interest.
DTI (debt-to-income): your monthly debts divided by your monthly income, the main test on a conventional loan.
DSCR (debt service coverage ratio): monthly rent divided by the property’s full monthly payment.
PITIA: principal, interest, taxes, insurance, and association dues, the full monthly carrying cost used in the DSCR calculation.
Reserves: liquid cash a lender wants you to hold after closing, usually counted in months of PITIA.
Common Mistakes
- Listing first. The line may no longer be available once the sign goes up.
- Treating an undrawn line as cash. It can be frozen or reduced.
- Skipping the source-of-funds question. Ask the DSCR lender whether borrowed down-payment money counts.
- Confusing 1.00x with profit. Coverage ignores repairs, vacancy, and capital costs.
- Borrowing to the ceiling. More debt on a home you are about to sell is a bigger payoff at closing.
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.
Frequently Asked Questions
Can I get a HELOC after my home is listed for sale?
Sometimes, but plan as though you cannot. Many lenders decline a listed home, and in a few states a property listed in the past 60 days is ineligible outright. Elsewhere it depends on the lender’s own guidelines. Open the line first.
Does HELOC money count as my down payment on a DSCR loan?
It depends on the program. Some DSCR lenders accept borrowed funds, and others want part of the down payment from your own seasoned cash. Confirm the source-of-funds rule before you sign the purchase contract. Typical purchase leverage is 75%-80% LTV on an investment property, so the down payment is 20%-25%. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.
Can I take the HELOC with me to the new property?
No. The line is secured by the old home, and the sale pays it off. A line on the new property would be a separate application with its own approval.
How much can I borrow against a rental I already own?
On Lendmire’s network, an investment-property line caps at $500,000 and 70% CLTV, with a 700 minimum credit profile. Market-wide figures can run higher, but those are not what the network offers. Every file is underwritten individually.
Does clearing 1.00 coverage mean the new rental will cash flow?
No. DSCR compares rent to PITIA only. Vacancy, repairs, management, and capital expenses sit outside the ratio, and so does your HELOC payment. A file that clears 1.00x can still lose money each month.
