The Quick Read: A home equity line of credit can supply the down payment on a third rental, but it never replaces the purchase loan. The line is one approval based on your credit, income and equity. The purchase is a second approval based on the new property’s rent. Treat them as two separate files.
- On an investment property, a line from Lendmire’s wholesale network tops out at 70% combined loan-to-value, with a 700 minimum credit score and a $500,000 maximum line.
- A line on your primary home can reach 90% combined loan-to-value, but only at a 720-or-better credit profile.
- A DSCR purchase loan typically lands at 75%-80% loan-to-value, so you still need real cash down.
- Clearing 1.00 on coverage does not mean the deal makes money, because the HELOC payment sits outside that ratio.
- Network lines are available only in 16 full-service states, a narrower footprint than DSCR lending.
What an Investment Property HELOC Actually Is
A HELOC is a revolving credit line secured by a property you already own. You borrow against equity, which is the gap between what the property is worth and what you owe on 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.
A line on a rental works much like one on your home, but fewer lenders offer it. Experian notes that investment-property lines are less common and that a typical draw period runs about 10 years with interest-only payments. That is a market-wide description.
The investment line in Lendmire’s wholesale network is different. It is a standalone line in first or second lien position. It has a 5-year interest-only draw followed by a 25-year repayment period where principal is paid down. Pricing floats during both phases and never converts to a fixed structure. Lines run from $25,000 to $500,000 on an investment property.
Lendmire is a broker, not the lender. Every figure here is subject to lender guidelines and a full file review.
Why Property #3 Is a Different File
By the third purchase, the lender is no longer looking at a clean slate. You carry two mortgages, perhaps a line already, and a larger pile of reserves to document.
Two network limits start to matter. A borrower can hold only three lines at once, and a borrower with more than 15 financed properties is not eligible. Most investors buying their third property are nowhere near either wall. Still, it helps to know that the HELOC route has a ceiling that DSCR purchase loans do not share.
The bigger change is stacking. Each property now carries its own payment, and the line adds one more that rent from the new property does not cover.
Two Approvals, Not One
A common mistake is treating the HELOC and the purchase loan as one decision. They are two underwritings, run by different lenders, looking at different things.
1. Choose the collateral. The line sits on your primary home or an existing rental.
2. Apply for the HELOC. The lender reviews credit, documented income, debt-to-income ratio, equity and title. Debt-to-income on this line is capped at 50%, and the lender reviews your file on the interest-only payment calculated on the maximum draw.
3. Draw the funds. At least 75% of the line is drawn at closing. Move the money into your own account.
4. Apply for the DSCR purchase loan. That lender reads the new property’s rent against its own monthly obligation: principal, interest, taxes, insurance and any HOA dues. Your personal income is not the test.
5. Show the paper trail. The purchase lender will want to see where the down payment came from.
6. Carry all three payments. The old mortgage, the line and the new loan all need a source.
A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. The HELOC is the only step that reads your personal finances. That separation is the structural advantage of this combination.
Which Property Secures the Line?
The primary home is usually the easier line to get and allows more leverage. The existing rental is a narrower product with tighter limits. The table shows how the two compare on the network.
| Factor | Primary-home line | Existing-rental line |
|---|---|---|
| Max combined LTV | Higher than the rental line, with stricter credit standards | 70% |
| Maximum line | Above $500,000 possible | $500,000 total |
| Draw structure | 3-year or 5-year options | 5-year draw, 25-year repay |
| Valuation | Full appraisal above $500,000 | Usually automated valuation |
| Main risk | Home backs an investment bet | Rental backs another rental |
Lines above $500,000 are primary-home only, carry tougher credit standards, and require a full appraisal. Because an investment line caps at $500,000, it normally runs on an automated valuation with no traditional appraisal, though a borrower can request one.
One thing surprises people. On an investment line, a 720 score and a 700 score both reach 70%. Credit above 700 buys eligibility, not extra leverage. Seven hundred is a hard floor with nothing beneath it.
How Much Line Can Your Equity Support?
The formula is simple: property value times the allowed combined loan-to-value, minus what you already owe. Combined loan-to-value, or CLTV, adds every lien on the property together and divides by its value.
Run the numbers on a rental whose first mortgage equals 45% of its value. At a 70% CLTV ceiling, the room is 25% of the property’s value, and the $500,000 cap applies if that figure is larger. Convert that percentage to dollars on your own property with the calculator, which gives an illustrative estimate only.
Now compare that room to what the new purchase needs. A DSCR purchase typically asks for 20%-25% down, because most files land at 75%-80% loan-to-value. Select high-leverage programs reach 85% loan-to-value (15% down) with roughly a 700-plus score. You also need closing costs and reserves.
Nasdaq works a market-wide example with an 85% limit on a primary-home line. That is a market figure. On this network, the investment ceiling is 70% and 90% appears only on primary or second-home lines at 720-plus.
The draw rule deserves attention. Because at least 75% of the line is drawn at closing, you cannot open a large line and leave it idle as a safety net. Size it to the job. Every dollar drawn starts costing interest right away.
What the Purchase Lender Looks For
The purchase lender cares about three things: the property, you, and your cash.
The property. Coverage of 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.
You. Credit minimums vary. A 620 floor exists in parts of the network, most programs want around 660, and 700-plus unlocks the strongest leverage tiers.
Your cash. Reserves vary by lender, leverage, loan size and transaction type. Around six months of the full monthly obligation is common, and loans above $1,500,000 typically step up. Many lenders want reserves documented in addition to the cash used to close, so a draw sized exactly to the down payment can leave you short.
Source of funds is the part that trips people up. Line proceeds are usually documentable, since the lender can trace the draw from the HELOC account to yours. Ask before you draw, not after. Draw early enough that the deposit is seasoned and explained, and keep the statements clean.
A bigger down payment lowers the monthly obligation and can lift coverage. It never erases leverage caps, credit floors, reserve rules or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage. Lendmire’s complete DSCR loans guide walks through those tests in more depth.
Where the General Rule Breaks
Several edge cases can derail an otherwise clean plan.
LLC-held property. Network HELOCs require title in an individual’s name or a revocable living trust. LLCs, corporations, partnerships and irrevocable or land trusts cannot hold title. A rental already deeded to an LLC needs a vesting change first, or a DSCR cash-out refinance instead. DSCR purchase loans can often be vested in an LLC, subject to lender program eligibility.
Variable payments and balloons. The CFPB explains that draw-period payments may be interest-only, that variable-rate payments can change even if you borrow nothing more, and that a balloon payment is possible when the draw ends. Its HELOC overview adds that in some cases the full balance can come due at once.
Selling the collateral. Selling the property that secures the line generally means paying it off. Plan the exit before you borrow.
Credit history. A bankruptcy needs four years of seasoning from discharge or dismissal. Foreclosure-family events on investment files follow a seven-year path, or four years for a deed-in-lieu, pre-foreclosure or short sale.
Property type. Single-family, 2-4 units, PUDs, townhomes and condos, including non-warrantable condos, are eligible. Manufactured homes, co-ops, condotels, log homes, commercial and mixed-use are not offered.
Geography. Lendmire’s HELOC availability covers 16 full-service states. Its DSCR footprint spans 41 markets, including Washington, D.C.
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.
Does Clearing 1.00 Mean the Deal Works?
No. This is the misconception that costs investors the most. DSCR compares rent to the full monthly obligation on the new property and nothing else. Repairs, vacancy, management, utilities and capital expenses all sit outside it.
The HELOC payment sits outside it too.
Consider an investor whose new duplex clears a coverage ratio around 1.2x. That cushion belongs to the duplex. The line payment still comes from the old rental’s cash flow or your other income. Benzinga lists foreclosure risk on the collateral and negative cash flow as the main downsides of these lines.
Run a three-part stress test before drawing:
- Cover the new property’s full obligation with zero rent for a stretch.
- Cover the line payment if its pricing moves up.
- Confirm you can handle the end of the draw period, when principal payments begin.
If any step requires the next deal to work, skip the line. A third purchase funded with near-100% financing leaves little room for a vacant month.
Key Terms Defined
HELOC: A revolving credit line secured by a property you own, with a draw period and a repayment period.
CLTV (combined loan-to-value): The total of all liens on a property divided by its value.
DSCR (debt service coverage ratio): Monthly rent divided by the property’s full monthly obligation of principal, interest, taxes, insurance and any HOA dues.
Source of funds: The paper trail showing where your down payment came from.
Reserves: Cash a lender wants you to hold after closing, usually counted in months of payments.
Draw period: The stretch when you can borrow from the line, often with interest-only payments.
Who Should Use This Route, and Who Should Skip It
A HELOC fits an investor with real equity, steady income to carry the line, and a third property whose rent comfortably covers its own payment. It works best when the line is sized tightly and has a defined exit, such as paydown from rent or a later refinance.
Skip it if you would be stretching to make the draw payments, if your collateral is an LLC-owned rental, or if you are already near three lines or 15 financed properties.
There are alternatives. A DSCR cash-out refinance on an existing rental tops out around 75% loan-to-value across most of the network, with about six months of seasoning common, and it replaces your first mortgage rather than adding a payment. You can also use savings, or lower your leverage on the purchase. Lendmire’s piece Can I Use A HELOC To Buy Investment Property? covers the basic question.

Frequently Asked Questions
Can I use a HELOC as the down payment on a DSCR purchase?
Often yes, since line proceeds can usually be documented through your bank statements. The purchase lender still sets its own leverage tier, reserves and source-of-funds rules. Ask what it needs before you draw, because the draw timing affects how clean the paper trail looks.
Does the HELOC payment count against my DSCR?
Generally no. The ratio reads the new property’s rent against that property’s own monthly obligation. The line payment still comes out of your pocket, so it matters for your cash flow even though it does not change the coverage number.
What is the maximum CLTV on an investment property line?
On an investment property, the ceiling is 70% combined loan-to-value, with a 700 minimum credit score and a $500,000 maximum line. The 90% ceiling applies only to primary-residence and second-home lines at a 720-or-better profile. All figures are subject to lender guidelines.
Can my LLC-owned rental secure a HELOC?
No. Title must sit with an individual borrower or a revocable living trust. A rental already in an LLC needs a vesting change, or a DSCR cash-out refinance may fit better.
Will an appraisal be required?
Usually not on an investment line. Because lines cap at $500,000, they normally run on an automated valuation, though a higher CLTV may require a secondary valuation, and a borrower can request a full appraisal.
