The Quick Read: No single program is best for every borrower. The right line is the one that matches your equity, your credit profile, whether you plan to sell or keep the old home, and how the new property will be underwritten, so you should size the line before you list and test the new purchase before you draw.
- A HELOC (home equity line of credit) is a second source of cash that sits behind the home you already own. It supplies the down payment. It does not approve the new purchase.
- Open the line before the home goes on the market. In several states in our network, a property listed for sale, or listed within the past 60 days, is ineligible.
- On an owner-occupied home, the highest ceiling is 90% combined loan-to-value, and only at a 720 credit profile. On an investment property, the ceiling is 70%.
- At least 75% of the line is drawn at closing, so you start carrying most of the balance on day one.
- A DSCR purchase loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines, so the new rental must pass on its own.
What Does Best Actually Mean Here?
A program is best when it fits four things at once: how much equity you have, how much cash you need, how long you will carry two properties, and what the new lender will accept as a source of funds. Headline terms matter less than fit.
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.
Lendmire is a mortgage broker. It places files with a network of wholesale HELOC lenders, so it does not push one product. We see many lenders’ guidelines side by side, and the pattern is consistent. The line that looks more affordable on paper often fails on a detail such as property type, vesting, listing status, or credit tier.
Use these five tests to judge any program:
1. Occupancy. Is the line on your primary home, a second home, or a rental? The ceiling changes with each.
2. Combined leverage. How much of the home’s value will your first mortgage plus the new line consume?
3. Structure. How long is the interest-only draw, and what happens when repayment starts?
4. Eligibility. Does the property type, title, and listing status pass?
5. Exit. Can you pay the line off if the home sells, or if it does not?
How the Strategy Works, Step by Step
The sequence is simple. The timing is what trips people up.
1. Size the need. Add up the down payment, closing costs, and reserves for the new property. Most DSCR purchases land at 75% to 80% loan-to-value, which means roughly 20% to 25% down. Reserves are commonly around six months of the new property’s full monthly payment, though they vary by lender, leverage, and loan size.
2. Open the line before listing. Do this before a sign goes in the yard.
3. Draw the funds. Because at least 75% of the line is drawn at closing, size it close to what you need. It is not a standby cushion.
4. Move the cash and keep records. Funds usually sit in your own account before they go to the purchase. Some purchase lenders want to see them there for a period, so ask early.
5. Buy the new property. The purchase loan is underwritten on its own merits.
6. Exit. Either sell the old home and pay the line off from the proceeds, or keep the home and carry the line.
The payoff rule on a sale is firm. The CFPB’s consumer booklet on home equity lines says that if you sell your home, you are generally required to pay off the line in full. The same booklet says you could lose your home if you fall behind, and that a lender may reduce your line if the home’s value declines. A line can shrink before you ever use it.
Which Is the Best HELOC Program to Buy Before You Sell Your Home?
The best fit depends on your equity position and your plan for the old home. Here is how the main combinations sort out across the wholesale lenders we work with.
Strong equity, primary residence, 720 or better credit. This is the highest-leverage lane. The ceiling reaches 90% combined loan-to-value on lines up to $500,000. You can also choose a larger line, up to $750,000, but at a reduced 75% ceiling. The larger line opens at 700 or better, on a primary residence only, with a full appraisal.
Middle equity, 660 to 719. Ceilings of 85% combined loan-to-value are available on lines up to $500,000 at most credit levels in this range. At 700 or better, a line up to $750,000 is available at 75%.
Thin credit, 600 to 639. A 640 profile reaches 80% and a 620 profile reaches 70% on a primary residence. At 600, the ceiling is 60%. Lines at this level carry stricter overlays. Borrowers below 640 are limited to single-family residences with a clean 12-month housing history under one of the two programs.
Keeping the old home as a rental. An investment-property line has a 70% combined loan-to-value ceiling, with no higher tier, and a 700 credit floor. It runs the five-year draw and 25-year repayment structure only.
| Occupancy | Max CLTV | Credit needed |
|---|---|---|
| Primary, line to $500,000 | 90% | 720+ |
| Primary, line to $500,000 | 85% | 660+ |
| Primary, line to $750,000 | 75% | 700+ (720 on the longer-runway program) |
| Investment property | 70% | 700+ |
These figures are typical ranges drawn from select wholesale programs, not commitments to lend. Every file is reviewed individually.
A Percentage Example (No Dollar Math Needed)
Say your current home carries a first mortgage equal to about half its value. At an 85% ceiling, the line could reach roughly 35% of the home’s value. At 90% with a 720 profile, the room grows to about 40%. If you intend to rent the home out and the line sits on that investment property, a 70% ceiling leaves about 20% of the value. The line size cap and your credit tier can pull these numbers down further.
Now compare that room to the purchase need: 20% to 25% down on the new rental, plus closing costs and reserves. The primary-residence lane often covers that. The investment-property lane may leave you short. That gap explains why timing and occupancy matter so much.
One more point is easy to miss. If you fund the entire down payment this way, you are borrowing most or all of the purchase price. A BiggerPockets discussion on using home equity as a down payment makes the same observation: the investor is essentially financing the whole property. The new rental has to carry that load.
What the Purchase Lender Will Check
The new loan is a separate approval. A DSCR loan compares monthly rent to the full property payment: principal, interest, taxes, insurance, and any association dues. 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.
Here is what that means in practice:
- Coverage. 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 open better pricing and leverage.
- Credit. A 620 floor exists in parts of the network. Most programs want around 660. A 700 or better profile unlocks the strongest leverage tiers.
- Reserves. These vary. Many files see about six months of the full payment, and loans above $1,500,000 typically step up to about nine months.
- Source of funds. The lender will want to see where the down payment came from. A line that is documented and in your account is easier to explain than one drawn the week before closing.
A DSCR ratio above 1.00 does not mean positive cash flow. The ratio looks only at rent against the payment. Repairs, vacancy, management, utilities, and major replacements sit outside it. Add a line payment on top of that and a thin margin disappears fast.
For the full mechanics of these loans, see Lendmire’s complete DSCR loans guide.
The HELOC Side of Qualifying
The line has its own approval, and the numbers are specific:
- Debt-to-income. The maximum is 50%, and 45% for credit profiles from 600 to 679. A ratio above 45% needs at least a 680 score. The lender reviews your file on the interest-only payment calculated on the maximum draw, not on what you plan to use.
- Credit report. A single-bureau score keyed to the primary wage earner, no more than 90 days old at closing, with no rescores.
- Valuation. Lines at or below $500,000 ordinarily run an automated valuation. A full appraisal is required on every line above $500,000, and you may request one in any case.
- Large lines. A line above $500,000 is primary-residence only. It needs a credit profile of 700 or better (720 on the longer-runway program, described below), and it is capped at 75% combined loan-to-value.
- Property. Single-family, 2-4 units, PUD, townhome, and condominium (including non-warrantable) are eligible. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural zoning are not offered.
- Exposure. You are limited to three lines, and an investor with more than 15 financed properties is not eligible.
There are two wholesale programs behind these figures. The higher-leverage program uses a three-year interest-only draw followed by a 17-year fully amortizing repayment. The longer-runway program uses a five-year draw followed by 25 years of repayment. Pricing floats on both and never converts to fixed. Tennessee shortens both structures. When you see a figure, it belongs to its own program’s terms.
A wealth-management firm’s guide to buying and selling at the same time also notes that a line draws on your home equity and can reduce your borrowing power when you apply for the next mortgage. Tell the purchase lender about the line at the start.
When Is the Window Open? Listing Status and Location
Timing is the first rule that can end the plan. In Indiana, North Carolina, Pennsylvania, Tennessee, Texas, and Washington, a property that is listed for sale, or was listed within the past 60 days, is ineligible. In other states, the answer varies by lender. The safe habit is the same everywhere: open the line before you list.
Availability is narrower than the DSCR footprint. The HELOC programs are offered in 16 full-service states: AL, CA, CO, FL, GA, IN, MI, MT, NM, NC, OH, PA, TN, TX, VA, and WA. The DSCR purchase side spans 41 markets, including Washington, D.C. A borrower can be eligible for the rental loan and not for the line.
Edge Cases Where the General Rule Breaks
The home is already listed. If you live in one of the restricted states, the line is off the table. A cash-out refinance, a bridge loan, or a contingent offer becomes the fallback.
The old home sits in an LLC. An equity line cannot be held in an LLC, corporation, partnership, or an irrevocable, blind, or land trust. Title must be held by you personally or in a revocable living trust. This is the sharpest difference from DSCR lending. A property already deeded to an entity needs a vesting change or a DSCR cash-out instead. Entity-titled DSCR loans are subject to program terms.
A Texas primary residence. A homestead caps at 80% combined loan-to-value. A waiting period, a one-lien-at-a-time rule, and 12 months of seasoning apply to primary residences only. Second homes and investment properties are treated as non-homestead transactions.
New Mexico and Ohio. The ceiling depends on the credit profile. Ask for the state-specific table.
Business bank accounts. If you want to use business deposits to qualify, the minimum score is 680. On a primary residence, where the floor is 600, a 640 borrower can get the line but cannot use business accounts.
Derogatory history. A bankruptcy needs four years of seasoning from discharge or dismissal on both programs. Foreclosure history splits: one program seasons a foreclosure at seven years and a deed-in-lieu or short sale at four, while the other declines the history regardless of age.
Line, Bridge Loan, or Cash-Out Refinance?
A HELOC is one of several ways to buy first. This comparison covers the structural differences.
| Option | Best for | Main risk |
|---|---|---|
| HELOC (second lien) | Keeping a low first mortgage | Must exist before listing |
| Bridge loan | Listed homes, short gaps | Higher cost, tight terms |
| Cash-out refinance | Long-term holds | Resets the first mortgage |
| Contingent offer | Low-cash buyers | Weaker offer to sellers |
A standalone line can sit in first or second lien position, so a second-lien line leaves an existing first mortgage in place. A cash-out refinance replaces that mortgage. If the old loan is better than anything you could get today, protecting it is a real advantage.
If you plan to keep the home and want to weigh the two structures, see Lendmire’s comparison of a DSCR HELOC vs DSCR cash-out refinance to buy before you sell your home.
What If the Old Home Does Not Sell?
This is where the strategy gets stress-tested. Run these checks before you draw:
- Carry the interest-only payment on both homes. The line is qualified on the maximum draw, so assume the full balance.
- Know the shift. When the draw period ends, repayment amortizes over 17 or 25 years. The payment steps up. Floating pricing means it can also change while you hold the line.
- Have an exit. You can cut the price, rent the home out, or pay the line down from cash flow. Investors also use a cash-out refinance on the new rental after seasoning. Cash-out refinances top out around 75% loan-to-value across most of the network, with about six months of seasoning as the common expectation.
- Check prepayment terms. DSCR loans commonly carry step-down prepayment penalties, so an early refinance can cost you.
The lesson from our deal flow is simple. Investors who run into trouble rarely misjudge the rent. They misjudge how long two payments will last.
Who Should Skip This Approach
Skip it if the home is already listed in a restricted state. Skip it if your new rental covers its payment with little margin. Skip it if you cannot carry both homes for an extended stretch. A smaller line and a larger cash cushion usually beat full leverage on a thin deal.
Key Terms Defined
- HELOC: a revolving line of credit secured by the equity in a home.
- 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 and pay interest only.
- Seasoning: the waiting period a lender wants between two events, such as owning a property before a cash-out refinance.
- DSCR: debt service coverage ratio, the property’s rent divided by its full monthly payment.
- Vesting: how title to the property is held, whether in your name, a trust, or an entity.
Frequently Asked Questions
Can I open a line after my home is listed?
In Indiana, North Carolina, Pennsylvania, Tennessee, Texas, and Washington, no. A property listed, or listed within the past 60 days, is ineligible. Elsewhere it depends on the lender, and many will not open one. Apply before you list.
How much can I borrow on a rental instead of my primary home?
An investment-property line has a 70% combined loan-to-value ceiling and a 700 credit floor. A primary residence reaches 90%, but only at a 720 profile. Lines above $500,000 are primary-residence only.
Does the line count against me on the new DSCR loan?
The purchase lender qualifies the new loan primarily on property-level rental income. How your line payment is treated depends on the program and the lender. Disclose the line at the start and expect a source-of-funds review.
Do I have to draw the whole line?
Close to it. At least 75% of the line is drawn at closing on both programs, so size the line near what you need. Later draws carry a $1,000 minimum, and $4,000 in Texas.
Is a bridge loan better?
Only in specific cases, such as when the home is already listed. A bridge loan is built for the gap but is usually costlier and shorter. A line may cost less, though it must be in place first.
