The Quick Read: A home equity line supplies the cash, a separate DSCR loan buys the rental, and each is underwritten on its own file, so you have to clear a borrower test on the line and a property-rent test on the purchase.
- The line is judged on you: credit, equity, debt-to-income, and the property that secures it.
- The DSCR loan is judged mainly on the target property’s rent compared with its own monthly housing cost.
- On most DSCR files, the line’s payment is not part of that rent-to-payment ratio. It still drains your real cash flow.
- On the network Lendmire brokers through, an investment-property line caps at 70% CLTV, needs a 700 credit minimum, and tops out at $500,000.
- The purchase program must accept borrowed money for the down payment. Programs differ, and reserves are usually the sticking point.
DSCR stands for debt service coverage ratio. It divides a property’s monthly rent by that property’s own monthly housing cost.
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.
Key Terms Defined
HELOC: A home equity line of credit is a revolving loan secured by property you already own, which you draw on as needed.
CLTV: Combined loan-to-value adds every loan secured by the property and divides the total by its value.
PITIA: Principal, interest, taxes, insurance, and association dues make up the property’s full monthly housing cost, and it is the bottom half of the DSCR formula.
Draw period: The stretch of time when you can borrow from the line, usually paying interest only, before repayment begins.
Seasoning: A waiting period lenders want between two events, such as a draw landing in your account and the purchase closing.
Reserves: Liquid savings left over after closing, held as a cushion against vacancy or repairs.
Can You Get a HELOC on an Investment Property?
You can, in some cases, but it is harder than getting a line on your own home. Yahoo Finance reports that lines on investment properties are less common and harder to get than lines on a primary residence. Investors use the line two ways: secured by their primary home, or secured by a rental they already own.
The primary-home route is more common. Fewer lenders will place a lien on a rental, and they scrutinize it more closely.
The network Lendmire works through offers lines on investment properties, with firm limits. The ceiling is 70% CLTV. The credit minimum is 700, and 720 buys no extra leverage on an investment line. The maximum line is $500,000. Primary-residence and second-home lines can reach 90% CLTV, but only with a 720 or better credit profile.
One structural point matters before anything else. You cannot open a line on a property you do not own. If you have no home or rental carrying equity, you have nothing to borrow against, and this strategy does not apply to you.
What Does the Line Itself Require?
The line is a borrower-based loan. The lender looks at your credit, your equity, your other debts, and the collateral. It does not ask what the rental you want to buy will earn.
On an investment-property line, the network’s typical guidelines look like this, subject to lender guidelines and full file review:
- Credit: a 700 minimum. The report can be no more than 90 days old at closing.
- CLTV: 70% maximum, counting your first mortgage plus the new line.
- Line size: $25,000 to $500,000 for investment collateral.
- DTI: 50% maximum, with lower limits for weaker credit profiles. The lender reviews your file on the interest-only payment calculated on the maximum draw.
- Structure: a 5-year interest-only draw followed by a 25-year repayment. The pricing floats the whole way and never converts to fixed.
- Draw at closing: at least 75% of the line is drawn when you close.
- Valuation: investment lines of $500,000 or less commonly use an automated valuation with no traditional appraisal, though you can request a full appraisal.
- Property types: single-family, 2-4 units, PUDs, townhomes, and condos, including non-warrantable ones.
- Not eligible: manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural zoning.
The appraisal point differs from the broader market. Valuation rules vary by lender, so ask before you assume.
Three more rules catch people. A borrower can hold only three lines at once, and anyone owning more than 15 financed properties is not eligible. A bankruptcy needs 4 years of seasoning, and investment files follow a 7-year path after a foreclosure and 4 years after a deed-in-lieu or short sale. The line side is also offered in a narrower set of states than the DSCR side, which spans 41 markets, including Washington, D.C.
The 75% draw rule shapes your plan. You will carry interest on most of the line from day one, whether or not you need all of it.
Which Property Should Secure the Line?
Your primary home usually gives the best combination of leverage and simplicity. A rental you already own works if it has the equity, but the leverage is lower and the seasoning rules are stricter.
| Collateral | Max CLTV (network) | Main catch |
|---|---|---|
| Primary home | Up to 90% at 720+ | Puts your own home at risk |
| Existing rental | 70% | Needs equity and seasoning |
| Property held in an LLC | Not eligible | Title must change first |
On the second row, a rental bought recently usually has to age first. If you acquired it within about six months of applying, expect to wait.
The third row is the sharpest difference from DSCR lending. The line’s collateral must be titled to you as an individual or to your revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. A rental already deeded to an LLC needs a title change before it can secure a line, or a DSCR cash-out refinance instead. The DSCR loan itself can close in an LLC, subject to lender program eligibility.
The risk of the primary-home route is plain. BiggerPockets investors who describe pairing a line with a DSCR loan as near-100% financing also note that the new property has to cash flow its own mortgage plus the line. One commenter asks whether you are willing to risk your primary residence. That is the right question.
How Does DSCR Treat the Line?
It treats the line as a separate matter. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. The ratio is monthly rent divided by the new property’s PITIA. The ratio contains no personal income and no line payment.
That is why people get confused. These are two loans with two tests:
| Item | The HELOC | The DSCR purchase loan |
|---|---|---|
| What is judged | You and the collateral | The target property’s rent |
| Key ratio | CLTV and DTI | Rent ÷ PITIA |
| Income review | Borrower income and debts | Rent on the property |
| Who decides | The line’s lender | The purchase lender |
Plenty of investors expect the opposite, partly because income-based loans work differently. On a conventional purchase, BiggerPockets investors plan on the minimum line payment being counted in DTI. That is accurate for loans underwritten on personal income, and it does not carry over to DSCR.
The payment is still real money. It does not disappear from your bank account because the lender left it out of a formula.
Clearing 1.00 also does not mean positive cash flow. The ratio compares rent to PITIA only. Repairs, vacancy, management, utilities, and capital expenses all sit outside it.
On coverage, 1.00 is where many select programs start. A separate select-lender path goes below 1.00, with leverage and terms adjusted. Stronger ratios open better pricing and leverage.
What Does the Purchase Loan Need for the Down Payment?
Across the network, most DSCR purchases land at 75% to 80% LTV, which means 20% to 25% down. Select programs reach 85% LTV, or 15% down, with roughly a 700 or better score. Short-term-rental purchases go up to 75% LTV, and those files typically expect a 640 or better score and about 12 months of hosting history. Standard rental purchases follow the tiers above.
The remaining requirements apply to every purchase:
- Credit: a 620 floor exists in parts of the network. Most programs want around 660, and 700 or better unlocks the strongest leverage.
- Coverage: typically 1.00 or better on select programs, as described above.
- Loan size: up to $3,000,000 on standard programs (smaller balances available through select lenders). Above $2,500,000, the network generally holds to 30-year fixed structures.
- Property types: the network does not offer DSCR on manufactured homes, log homes, or barndominiums.
A bigger down payment lowers the loan and the monthly obligation, which lifts the ratio. It never erases leverage caps, credit floors, reserve rules, or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage.
Lenders test three buckets separately: the down payment, closing costs, and reserves. A program can accept borrowed money in one and refuse it in another. Across the network, a common pattern is that documented borrowed funds are accepted for the down payment and closing costs but excluded from reserves. Reserves are commonly around 6 months of PITIA, though they vary by lender, leverage, loan size, and transaction type. Conservative rate-and-term files at modest leverage under $1,500,000 can see reserves waived, and larger loans typically step up to about 9 months.
Some programs go further and ask for a minimum amount of your own unborrowed money. A fully borrowed down payment can fail on that rule alone. Large retail lenders often resist borrowed down payments altogether.
A Worked Example in Percentages and Ratios
Run the numbers on an investor who owns a primary home with a 720 credit profile. The existing mortgage equals 50% of the home’s value. At the 90% CLTV ceiling for primary residences, the most the line could add is 40% of the home’s value. That is the theoretical ceiling. The lender’s valuation, DTI, and credit review set the actual number.
Now size the need. Suppose the target rental costs half of what your home is worth, and you buy at 75% LTV. The down payment is 25% of the price, or 12.5% of your home’s value, plus closing costs. The line covers that comfortably, and you would draw roughly that much. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
Next comes the property test. Assume the rental’s rent clears about 1.25x against its own PITIA. That is comfortably above 1.00, so the DSCR loan stands on its own.
Then run the combined test, which no ratio does for you. Take the rent. Subtract the property’s PITIA. Subtract the line’s payment on the amount you drew. Then subtract a realistic allowance for repairs, vacancy, and management. If what remains is thin or negative, the purchase works on paper and strains you in practice.
Try the same file with the line secured by an existing rental instead of your home. The ceiling falls to 70% CLTV, and the same equity buys much less room. Many investors find that the primary home is the only collateral with enough capacity.
DSCR vs. conventional financing
There are two common ways to finance an investment property, and they qualify you differently — here’s how investors weigh them.
Why investors choose it
- Qualifies on the property’s rental income — no personal tax returns, W-2s, or pay stubs needed to document income.
- No personal debt-to-income ceiling to clear, so existing mortgages and obligations don’t cap your borrowing the same way.
- Can be closed in an LLC, keeping the property inside a business entity.
- Built for scaling — not held to the limit on number of financed properties that conventional financing applies.
- Underwriting centers on the deal: generally qualifies when the rent covers the payment, a 1.00x coverage ratio being a common baseline (confirmed in underwriting).
- Designed specifically for investment property, including long-term and, where the program allows, short-term rentals.
Where it’s strong
- Often the lowest ongoing financing cost for a buyer who fully qualifies on personal income — a fit for a first property or a cost-first purchase.
Trade-offs for investors
- Requires full personal income documentation and must fit within a debt-to-income limit — salary, existing debts, and other mortgages all count.
- Typically held in your personal name rather than a business entity.
- Caps how many financed properties you can carry, which can become a ceiling as a portfolio grows.
- Evaluates you as a borrower as much as the property, which usually means more paperwork.
How investors usually choose: a first or single property often optimizes for the lowest financing cost; portfolio builders often optimize for leverage, vesting in an LLC, and scaling past conventional caps. The right answer depends on your goals, the property, and current guidelines — both paths run through select lenders in Lendmire’s wholesale network, with eligibility and terms confirmed in underwriting.
What Order Does Everything Happen In?
The sequence matters more than people expect: line first, purchase second.
1. Confirm the purchase program accepts borrowed funds. Ask whether it requires own-money minimums and how it treats reserves.
2. Open and fund the line before you shop seriously. The line must be approved before you write an offer.
3. Draw into your own account. Let the funds show on your statements. Underwriters want the deposit traceable to the line, not an unexplained cash infusion.
4. Go under contract and apply for the DSCR loan. The lender reviews the rent schedule from the appraisal, which uses Form 1007 on a single-family home or Form 1025 on 2-4 units.
5. Document each bucket. Keep separate evidence for the down payment, closing costs, and reserves.
One caution applies to gift funds. A lender underwrites gift money as a different source type from line proceeds, so do not assume the same rules cover both. A pre-draw call to your loan officer saves an expensive surprise.
Where the General Rule Breaks
The idea that the line does not touch DSCR holds in most cases, but it has edges.
- A fully borrowed purchase. BiggerPockets investors call a line a strong source of down-payment funds, with one caution: the buyer has no equity in the property when borrowed money funds the whole purchase. Some DSCR programs make you put in a minimum of unborrowed cash.
- Reserves. Even when the draw is accepted for the down payment, reserves are often required in unborrowed form.
- Source-rental seasoning. A rental you bought recently may not yet qualify as collateral.
- Short-term rentals. The line’s payment stays out of the new property’s ratio. Some programs cap the borrowed share or require unborrowed funds. Short-term rental rules can vary by city, county, HOA, and property type, so confirm local rules before relying on projected rental income.
- An LLC-owned rental. The line cannot attach to it unless title moves into your name or trust.
- A first-time investor. With no equity-bearing property, there is no line to draw on.
HELOC, HELOAN, or Cash-Out Refinance?
| Item | HELOC | Fixed-sum home equity loan | DSCR cash-out refinance |
|---|---|---|---|
| Structure | Revolving line | One lump sum | Replaces first mortgage |
| Pricing | Floats | Typically fixed | Per program |
| Collateral | Home or rental | Home or rental | The rental |
| Typical cap | 70% CLTV on investment | Varies by lender | About 75% LTV on standard rentals |
A cash-out refinance on a standard rental generally tops out around 75% LTV, and about 6 months of seasoning is the common expectation. Short-term-rental collateral is lower, around 70% on a cash-out. Unlike the line, a cash-out refinance reviews the property’s qualifying rent, so it can suit investors whose personal debt ratios are tight. It also replaces your first mortgage, which matters if that loan is one you want to keep.
Investors use the line differently after the purchase. Some pay it down from cash flow, as BiggerPockets members describe. Others plan to refinance out of it, which fits the DSCR cash-out refinance in the table above.
What Is the Real Risk of the Line?
The risk is a variable payment on a balance you drew in a single month. The Consumer Financial Protection Bureau explains that a HELOC is an open-end line you can borrow against repeatedly during a draw period. It notes that these lines usually carry variable rates, so payments can change month to month.
On an investment line, the pricing floats through both the draw and the repayment period. Stress-test two moments: the interest-only draw, and the day amortization begins. The second payment is the one that surprises people.
A short list of habits protects the deal:
- Plan a payoff path before you draw, whether paydown or refinance.
- Size the draw to the real need, remembering the 75% minimum at closing.
- Keep your own reserves separate from the borrowed cash.
Frequently Asked Questions
Does the line payment lower my DSCR?
On most DSCR files, no. The ratio uses the new property’s rent and its own PITIA, and the line’s payment is generally left out. The payment still reduces your actual monthly cash flow, and it still appears on your credit.
Can I use a HELOC for the whole down payment?
Sometimes, depending on the program. Many programs accept a documented draw for the down payment and closing costs. Others require a minimum of unborrowed money, and reserves are commonly excluded from borrowed funds.
Can borrowed money count as reserves?
Usually not. Programs commonly exclude it, so plan to keep unborrowed savings, often around 6 months of PITIA, subject to lender guidelines.
Is HELOC interest tax deductible?
Sometimes, but it is not automatic. Tax treatment can depend on how the funds are used and how the property is held; borrowers should keep clear records and speak with a qualified tax professional before relying on any deduction.
Which is better, a line on my home or on a rental?
It depends on equity and risk tolerance. A primary-residence line can reach 90% CLTV at a 720 or better profile, while an investment line caps at 70% CLTV. The home route offers more room and puts your residence at stake.
