The Quick Read: Get the line from the bank, credit union, or broker-placed program that will hold the second lien on the home you currently own, and have it open before that home is listed, because lenders generally will not approve a line on a house already on the market and the balance is due when the house sells. The line supplies cash only. A separate purchase loan buys the new property, and that lender decides whether borrowed money can count toward your down payment.
- Timing decides everything. NerdWallet says a lender won’t approve a credit line once the listing goes live.
- Each lender runs its own approval. The line’s approval and the purchase loan’s approval are separate files.
- Capacity is often smaller than expected. It depends on combined loan-to-value, not the home’s price.
- On an investor purchase, the line payment sits outside the DSCR ratio. It still comes out of your real cash flow.
- Across Lendmire’s wholesale network, equity lines come only through select partners, and only in 16 states.
How Does Buying Before Selling Work With a HELOC?
A home equity line of credit (HELOC) lets you borrow against the equity in the home you already own. You open the line, draw cash, and use it for the down payment and closing costs on the next property. When the old home sells, the sale proceeds repay 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.
Here is the sequence, start to finish:
1. Size your equity and check what a lender would let you borrow.
2. Apply for and open the line before you list.
3. Draw cash for the down payment and closing costs.
4. Qualify for the purchase loan on the new property.
5. Close on the new property, then list and sell the old one.
6. Repay the line from sale proceeds.
The stakes sit in step two. Skip it and you are shopping for a bridge loan instead.
Why do investors bother? A funded line lets you make an offer with no sale contingency. That is a promise to the seller that your purchase doesn’t depend on selling your current home. NerdWallet notes that a contingency can make an offer less attractive to a seller because it adds uncertainty.
Key Terms Defined
HELOC: An open-ended line of credit secured by your home. You borrow what you need, up to a limit, during a set draw period.
Draw period: The stretch when you can take money out. After it ends, the balance starts paying down on a fixed schedule.
Second lien: A loan secured by your home that sits behind your first mortgage. If the home sells, the first mortgage is paid first.
CLTV (combined loan-to-value): Your first mortgage plus the new line, divided by the home’s value. It is the number that caps how much you can borrow.
DSCR (debt service coverage ratio): The new rental’s monthly rent divided by its monthly mortgage payment, including principal, interest, taxes, insurance, and any HOA dues.
PITIA: Principal, interest, taxes, insurance, and association dues. It is the payment side of the DSCR ratio.
DTI (debt-to-income): Your monthly debt payments divided by your monthly income. Equity lines are underwritten on it.
Sale contingency: A clause that lets you back out of a purchase if your current home doesn’t sell.
Where Can You Get One? Lender Types Compared
The line comes from whoever will hold the second lien on the home you own now. That is a different party from the lender on the new purchase. The main sources look like this:
| Source | Who it suits | Watch-outs |
|---|---|---|
| Large retail bank | Borrowers with an existing banking relationship | One set of guidelines; investment-property use may be restricted |
| Credit union | Members with a primary residence and steady income | Membership rules; policies on funds for another property vary |
| Broker-placed program | Borrowers who want several lenders compared | Availability depends on state and property type |
| Online lender | Borrowers comfortable with a remote process | Check listed-home rules and early-closure terms |
Every row has the same catch. No federal rule bars a line on a home that is about to be listed. The restrictions come from each lender’s own policy, so the answer changes by institution.
A broker sees many lenders’ guidelines at once, and that is the practical edge of the broker route. Lendmire places home equity lines through select wholesale partners in its 16 full-service states: AL, CA, CO, FL, GA, IN, MI, MT, NM, NC, OH, PA, TN, TX, VA, and WA. That is narrower than its 41-market DSCR footprint. Outside those 16 states, your options are the banks and credit unions near you.
What Do Equity Lines Allow Across the Network?
The ceiling depends on how you use the home, and the numbers differ a lot. Across the wholesale partners Lendmire works with, the top combined loan-to-value looks like this, subject to lender guidelines and full file review:
| Occupancy | Top CLTV | Credit pairing | Max line |
|---|---|---|---|
| Primary residence | 90% | 720+ | $500,000 |
| Primary residence | 75% | 700+ (720 on the longer-runway program) | $750,000 |
| Second home | 90% | 720+ | $500,000 |
| Investment property | 70% | 700+ | $500,000 |
Lower credit tiers on primary residences step the ceiling down, with the lowest tiers carrying the most conservative combined loan-to-value limits. A line above $500,000 is for primary residences only. It takes a credit profile of 700 or better (720 on the longer-runway program, described below), caps at 75% CLTV, and requires a full appraisal.
If the home you are selling is your primary residence, the first two rows are the ones to plan around, and the 90% row applies only with a 720 or better credit profile. If the home is a rental you are cashing out of, plan around 70%.
A few mechanics matter more than the ceiling:
- Two draw structures exist on primary residences and second homes. One has a 3-year interest-only draw and a 17-year repayment period. The other, the longer-runway program, has a 5-year draw and a 25-year repayment period. Investment lines use the 5-year structure only.
- At least 75% of the line is drawn at closing. You can’t open a big line and leave it untouched as a safety net. You carry interest on most of it from day one.
- The price floats. The line never converts to a fixed amount, and the payment can change over time.
- DTI tops out at 50%. It is 45% for credit profiles from 600 to 679. Qualification uses the interest-only payment calculated on the maximum draw, not on what you actually drew.
- Lines at or below $500,000 ordinarily use an automated valuation. There is no traditional appraisal unless a higher CLTV calls for a second look.
Title matters too. The property must be held by you personally or by a revocable living trust. An LLC can’t hold title on these lines. That is a sharp difference from a DSCR loan. If your old home is already deeded into an entity, you would need a vesting change, or a DSCR cash-out refinance instead.
How Does Underwriting Treat the Line, Step by Step?
Underwriting for the line looks at your credit, income, DTI, and the home’s value and equity. A lender sets your limit by taking a percentage of the appraised value and subtracting what you owe. Practitioners write it as maximum CLTV times value, minus the first mortgage balance.
The result is often smaller than borrowers expect. A home worth a lot with a large first mortgage can leave a thin slice. According to the CFPB’s overview of how HELOCs work, set-up and third-party costs can apply, and some plans require an initial draw or minimum draws. Here, the network sets the minimum subsequent draw at $1,000 after closing on one of its two draw structures.
Credit is read from a single-bureau score tied to the primary wage earner, and the report can be no more than 90 days old at closing. Bankruptcy needs 4 years of seasoning from discharge or dismissal. Foreclosure history splits by program. One seasons a foreclosure at 7 years and a short sale or deed-in-lieu at 4. The other declines that history regardless of age.
Property type narrows the field, too. Single-family, 2-4 units, PUDs, townhomes, and condos (including non-warrantable ones) are eligible. Manufactured homes, co-ops, condotels, log homes, and commercial, mixed-use, or agricultural properties are not.
A borrower can hold three lines at most. Anyone with more than 15 financed properties is not eligible. That second limit is easy to overlook for a seasoned investor.
What If Your Home Is Already Listed?
Listing first is where many plans run into trouble. Lenders generally won’t open a line on a home that is for sale. NerdWallet reports that some lenders won’t approve an application if the home was listed within the past 90 days. That is a market-wide figure, not a network one.
On Lendmire’s network, a property listed for sale, or listed within the past 60 days, is ineligible in six states: Indiana, North Carolina, Pennsylvania, Tennessee, Texas, and Washington. Policies in the other states vary by lender. Waiting until after the listing makes the options harder.
If you are past that point, you have three workarounds:
- Use equity in a different property. A rental you own may carry a line on its own terms, but investment lines run tighter. The network requires a 700 score and a 70% CLTV ceiling.
- Use a bridge loan. NerdWallet describes bridge loans as typically running up to 12 months with no prepayment penalties. They cost more and the old home still has to sell.
- Make a contingent offer. It costs you nothing upfront. It also hands the seller a reason to pick someone else.
Where Does the General Rule Bend?
Four edge cases come up often.
Borrowed funds versus reserves. Down payment, closing costs, and reserves are three separate buckets. A DSCR lender may accept borrowed funds for the first two and not for reserves. Another lender may accept them for neither. Treat it as a program-by-program question, and ask before you draw.
A lender that refuses the use. Some depository lenders won’t allow an equity line to fund an investment purchase. Others don’t care what you spend it on. Ask at application, and read how the line agreement describes permitted use.
Keeping the old home as a rental. The line can stay open if you keep the house. But the line agreement may restrict renting the home out, and a line on a former residence is underwritten as an owner-occupied loan. Converting that home to a rental can raise questions with the lender. The payment then has to be covered by rent or other cash flow.
The line shrinks or freezes. Per the CFPB’s HELOC brochure, lenders can reduce or freeze a line if the home’s value falls or your ability to repay is in doubt. A falling market in the middle of your plan is a real risk. If the line freezes before you draw, you lose your down payment source.
One more distinction. A “DSCR HELOC” is a line on an existing rental. It is a different structure from the one here.
How Does the DSCR Purchase Loan Treat the Line?
A DSCR purchase loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. The line’s payment generally isn’t part of that ratio. The new rental only has to cover its own PITIA.
Here is what that means for the loan itself. Across the network, most purchase files land at 75%-80% LTV, meaning 20%-25% down. Select high-leverage programs reach 85% LTV on a purchase (15% down), typically with a score around 700 or better. Credit floors run from 620 in parts of the network, to around 660 on most programs, to 700 and up for the strongest tiers. Loans typically reach up to $3,000,000 on standard programs, with smaller balances available through select lenders. A DSCR of 1.00 is where many select programs start. A separate select-lender path goes below 1.00, with leverage and terms adjusted. Stronger coverage opens better pricing and leverage.
Reserves vary with lender, leverage, loan size, and transaction type. Around 6 months of PITIA is common. Don’t assume your down payment line also covers reserves. The strongest files clear both tests: enough equity and enough rental coverage, as outlined in Lendmire’s complete DSCR loans guide.
Clearing 1.00 does not mean positive cash flow. Repairs, vacancy, management, utilities, and capital expenses sit outside the ratio. The line payment sits outside it too. Add the two and you get the number that matters, the property’s rent against its payment plus the line.
A larger down payment lowers the monthly payment and can lift the ratio. It never erases leverage caps, credit floors, or reserve rules. And leverage stacks. A line covering the down payment plus a loan for the rest leaves you at 100% financed across two separate loans. The line is paid back whether or not the rental performs.
Also check the prepayment terms on the DSCR loan. A line-funded down payment plus a loan with a prepayment penalty cuts your flexibility if you want to refinance out.
A Worked Example
Run the numbers on a modeled primary residence. Assume a credit score of 700 or better, a line of up to $750,000, and a ceiling of 75% CLTV. The first mortgage sits at 45% of the home’s value. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
- Room under the ceiling: 75% minus 45% equals 30% of the home’s value.
- At least 75% of the line is drawn at closing, so roughly 22% of the home’s value is borrowed from day one.
- If the new rental costs about what your current home is worth, a 20%-25% down payment on a standard purchase fits inside that room, with a little left for closing costs. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
Then the exit. NerdWallet warns that selling costs commonly run 10% to 15% of the sale price once agent commissions and closing costs are in. So the equity you walk away with is smaller than the equity on paper. The line gets repaid first.
The new rental, modeled at around 1.2x coverage, passes on its own. That says nothing about whether you can carry the line and a vacant month. The honest read is that this works, but the thin margin is the line payment itself.
What If the Old Home Takes Longer to Sell?
Stress-test the plan before you commit. Ask what happens if the sale slips by several months and the line balance sits at its maximum.
You carry the first mortgage, the line, the new loan, and the upkeep on two homes. NerdWallet puts it plainly: you could be stuck paying the mortgage and maintenance on two homes at once. Because the line is interest-only during its draw period and floats, the payment can also change while you wait. Plan for the high end.
Two fallbacks exist. You could rent the old home out, if the line terms and the lender allow it. Or you could reduce the line before listing. Skip any plan that depends on the sale happening on a date.
Questions to Ask Any Lender
Take this list to every lender before you apply:
- Will you open a line if I plan to list within the next few months?
- Does a recent listing disqualify me, and for how long?
- Can the funds go toward a down payment on an investment property?
- Is there a minimum draw at closing?
- What happens to the line when I sell? Is there an early-closure fee?
- Can the line stay open if I keep the home as a rental?
- How is my credit limit calculated, and what is the ceiling for my occupancy type?

Frequently Asked Questions
Can I get a HELOC after my home is already listed?
Usually not. Lenders generally decline lines on homes already for sale, and some look back over a recent listing period. On Lendmire’s network, a property that is listed or was recently listed is ineligible in certain states, and the length of that lookback varies by lender and by file. If you are past the lookback window, a bridge loan, equity in another property, or a contingent offer are the realistic options.
Can I put the line on the new home instead of the old one?
You can look at it, but it works differently. On a new purchase, your DSCR or conventional loan comes first and the line sits behind it. On a rental, the investment-property terms apply: a 700 minimum score and a 70% CLTV ceiling on the network. The new property has to already be owned and carry equity first.
Does the line payment count in the DSCR calculation?
Generally no. The DSCR compares the new rental’s rent to its own PITIA. The line payment still reduces your real cash flow, and some lenders look at your overall debts alongside the ratio.
Can an LLC hold the property for a line?
No. Title has to be held by you individually or by a revocable living trust on the network’s equity lines. A property already in an LLC needs a vesting change, or a DSCR cash-out refinance in place of a line, subject to program terms.
What happens to the line when I sell?
It is generally repaid in full at closing from the sale proceeds. If you keep the home instead, the line stays open and must be serviced from rent or other cash flow. Check the line agreement for any limit on renting the home.
