The Quick Read: A rental HELOC is a revolving line secured by equity in a property you already own, and the draw funds the down payment on your next purchase while the existing first mortgage stays in place. The line is approved on your personal income, debt-to-income ratio, and credit, not on the rent. The purchase loan is a separate approval that reads the new property’s rent.
- On an investment property, the network ceiling is 70% combined loan-to-value (CLTV), with lines from $25,000 up to $500,000, subject to lender guidelines.
- Credit minimum on an investment line is 700. A 720 score buys no extra leverage on a rental.
- The CLTV test runs on the full line limit, not the amount drawn.
- Title must sit in an individual’s name or a revocable living trust.
- Qualifying on the line does not mean the purchase lender will treat the draw the way you expect. Ask before you draw.
Most investors who ask about this want one thing: keep a good first mortgage and still raise down-payment cash. A cash-out refinance replaces the old loan. A HELOC sits beside it. That difference is the whole reason this structure exists, and it comes with its own set of file mechanics.
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.
What Is a Rental HELOC, Exactly?
The term covers two different setups, and mixing them up causes most of the confusion. One is a line secured by a rental you own. The other is a line secured by your own primary residence, with the cash used to buy a rental. Both fund the next deal. They carry different risk and different ceilings.
A home equity line is a loan you borrow, spend, and repay as you go, with the property as collateral. The federal consumer-finance regulator HELOC brochure describes a borrowing period, called the draw period, followed by a repayment period. During the draw period some plans allow interest-only payments and others require principal plus interest. On a variable plan, payments can change even if you draw nothing more.
Across the wholesale network Lendmire works through, the investment version is a standalone line placed in first or second lien position. Second position behind an existing mortgage is the common use for this article’s purpose. A first-lien line is narrower and usually means the property is owned free and clear or the line pays off the old loan at closing.
| Factor | Line on the rental | Line on your primary home |
|---|---|---|
| Collateral at risk | The rental | Your home |
| Max CLTV | 70% on an investment property | Up to 90% on a primary residence, only at 720+ credit |
| Max line size | $500,000 | Up to $750,000 (above $500,000 needs 700+ and a full appraisal) |
| Credit minimum | 700 | 600 program floor, varies by tier |
| Title | Individual or revocable trust | Individual or revocable trust |
Run that table honestly. A primary-home line gives more leverage and a larger ceiling, but the home is what the lender can take if payments stop. The federal consumer-finance regulator Ask page on HELOCs makes the same point in plain terms: payments are often significantly higher once repayment begins. Some plans also require a minimum draw when the line is opened.
How Much Line Does Your Equity Support?
Maximum line equals property value multiplied by the CLTV cap, minus every lien already on the property. Then the dollar cap applies, and the smaller result wins. On an investment line the CLTV cap is 70% and the dollar cap is $500,000.
Take a rental valued at $600,000 with an existing first mortgage balance of $250,000. Seventy percent of value is $420,000. Subtract the $250,000 balance and the room is $170,000. That sits under the $500,000 cap, so the CLTV test is the binding limit. A larger, nearly paid-off property flips this: the $500,000 cap binds first.
The sizing method itself is not new. The older CFPB HELOC booklet lays out the same idea for home equity: take a percentage of appraised value, then subtract what is owed. Its worked example uses a home, not a rental, and a different percentage than the investment ceiling here.
Two points trip people up.
First, the CLTV test counts the full limit, not the drawn balance. Lenders add the first-mortgage balance and the proposed line limit, then divide by value. Opening a $200,000 line and drawing $50,000 still tests as $200,000.
Second, the cap is per property. Equity in Rental A does not back a line on Rental B. Each rental is its own collateral pool. A pooled portfolio LTV is a useful number for your own monitoring, not a lender cap.
Credit above 700 does not raise the investment ceiling. A 700 score and a 740 score both reach 70% CLTV on a rental. The 90% tier exists only for primary residences and second homes, and only at 720 or better.
The Two-Approval Sequence
A rental HELOC for the next deal involves two separate underwriting events that read different things. Mixing them up is the most common planning error.
1. Approval one: the line. The lender reviews you. Personal income, debt-to-income, and credit drive the decision, with a 50% maximum DTI on this network and a lower 45% ceiling for credit profiles from 600 to 679. Qualification runs on the interest-only payment calculated on the maximum draw, not the amount you plan to draw. Self-employed borrowers typically document income through bank statements, and personal DTI still applies.
2. Approval two: the purchase loan. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. The lender reads the new property’s rent against its monthly obligation. It does not rely on your W-2 picture the way the line did.
3. The handoff. The purchase lender reviews where the down payment came from. Money drawn from a line is borrowed money. Whether the lender accepts it, how it wants the paper trail documented, and whether it counts the line payment as a personal debt are lender-specific decisions.
Open and fund the line before you go under contract. A line opened after you have an accepted offer puts a new credit event and a new lien in the middle of a clock you do not control. Investors who set up the line ahead of need are the ones who move when a deal shows up.
Title, Entity, and Portfolio Limits
Title is the first hard stop. The rental securing the line must be held by an individual borrower or an inter vivos revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. That is the sharpest structural difference from a DSCR loan, where LLC vesting is common, subject to lender program eligibility.
If your rental already sits in an LLC, you have three options. Re-deed it into your name or a revocable trust, which can raise questions with your existing lender and your insurer, so check the loan covenants before you do. Secure the line with your primary home instead. Or use a DSCR cash-out refinance, which accepts entity ownership but replaces the first mortgage.
Other limits that surface on files:
- A borrower is limited to three lines in total across the network’s programs.
- Combined exposure caps at $2,000,000 on the higher-leverage program and $750,000 on the longer-runway program. The higher-leverage program is the one with a 5-year draw tied to a 25-year repayment on investment lines; the longer-runway program offers both a 3-year and a 5-year draw structure.
- A borrower who owns more than 15 financed properties is not eligible.
- Single-family, 2-4 unit, PUD, townhome, and condominium (including non-warrantable) properties are eligible. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned property are not eligible.
The line is also limited by geography. Lendmire’s HELOC placement runs in 16 full-service states, which is narrower than its 41-market DSCR footprint. A deal in a DSCR-only market may still close on the purchase side, while the line has to come from a covered state.
The Draw Structure: What You Cannot Skip
On an investment line, the network structure is a 5-year interest-only draw followed by a 25-year fully amortizing repayment. At least 75% of the line must be drawn at closing. Pricing floats through both the draw and repayment periods and never converts to fixed.
The 75% draw requirement changes the dry-powder idea. Many investors imagine a large undrawn line sitting ready. On this structure, most of it is drawn on day one, interest starts on the drawn balance, and the cash sits in an account until the deal needs it. Plan for carrying cost on money you have not deployed yet. After closing, the minimum subsequent draw is typically $1,000 on the longer-runway program, with Texas at $4,000.
Because pricing is variable, the payment can move. Investor discussion on this point is consistent: build variable-rate movement into your cash-flow projections, not just the day-one number. A balance still outstanding when the draw ends means principal payments on top of interest, which can lift the monthly obligation sharply.
How the Purchase Lender Treats the Draw
This is where files get stuck, and it is the least standardized part of the process.
The purchase lender decides three things: whether borrowed funds are an acceptable source for the down payment, how much documentation it wants, and whether the HELOC payment counts as a debt in its review. Lender guidelines are the only authority on each. Agency policy applies to agency loans, and it does not govern a DSCR file, so it should not be read as if it did.
For practical file prep, assemble this before the purchase lender asks:
- The closing documents for the line and its first statement.
- A bank statement showing the draw landing in a dedicated account, kept separate from operating funds.
- A short written explanation of the source if the lender’s source-of-funds review flags the deposit.
- Reserves documentation separate from the down payment. Reserves commonly run around 6 months of PITIA on DSCR files and vary by lender, leverage, loan size, and transaction type.
Draw only what the deal needs, and time the draw ahead of the purchase closing so the funds are seasoned in your account. A broker quoted in one BiggerPockets thread says a HELOC on the buyer’s primary residence is almost always permissible as a down-payment source. Treat that as one data point, not a rule. Acceptance is lender-specific, and investors in the thread note they disclosed the source up front.
Does the Line Payment Count Against the New Deal?
Two questions hide inside this one, and they have different answers.
The first is whether the HELOC payment enters the new property’s DSCR. DSCR compares the property’s rent to its own PITIA. A line secured by a different property is not part of the new property’s PITIA. Whether a particular lender counts personal debt in its separate review of you is a lender call, and there is no universal answer.
The second is whether you can carry it. DSCR measures the new property in isolation, and clearing 1.00 is not the same as positive cash flow. Repairs, vacancy, management, utilities, and capex all sit outside the calculation. If you stack a DSCR loan and a HELOC payment on one deal, the rent has to cover both for the deal to be comfortable, even though the ratio only tests one of them. One investor poster frames it exactly that way in a thread on down payments or full purchases.
DSCR programs on this network commonly start at 1.00 on select programs, with stronger ratios opening better pricing and leverage. A separate select-lender path takes coverage below 1.00 with leverage and terms adjusted. Purchase leverage typically lands at 75% to 80% LTV, with select programs reaching 85% LTV at roughly a 700 score. Credit minimums vary by program: a 620 floor exists in parts of the network, most programs want around 660, and 700 or better unlocks the strongest tiers.
Exits: Paying the Line Back Without Refinancing
The competing guidance on this topic tends to end in a refinance. This article’s premise is different, so look at the exits that do not replace your first mortgage.
| Exit | How it works | Trade-off |
|---|---|---|
| Pay down from cash flow | Rent surplus and personal income retire the balance during the draw | Slow; payment shock if balance remains at repayment |
| Pay down from rent growth | Lease increases or rehab-driven rents widen the margin | Depends on the market and the property |
| Pay at sale | Line balance retires from sale proceeds | Ties repayment to an exit you may not control |
| Refinance the new property | Cash-out on the new asset, with proceeds paying the line | Cash-out on the new deal tops out around 75% LTV, with about 6 months of seasoning expected |
A common investor strategy is to use the line as the down payment, then cash-out refinance the new property after value rises and pay the line down. Commenters on that approach say a line suits short-term projects, with rehab-created equity as the best case, as in this BiggerPockets discussion on a first investment purchase. Another contributor says a line can fund only one or two deals at a time, in a thread on down payments and scaling. Both are anecdotes, but they match what the mechanics suggest: a line is a bridge, not a permanent capital layer.
Plan the exit before the draw. A line with no repayment plan behind it becomes a payment-shock event when the interest-only period ends.
Where the General Rule Breaks
Five edge cases change the outcome of otherwise clean files.
- The line gets frozen or reduced before closing. If the lender reduces or suspends the line after you have an accepted offer, your down payment can vanish mid-deal. Draw the funds before you go under contract and park them in a separate account. Do not rely on an undrawn balance.
- The rental is in an LLC. Title blocks the line. Fix the vesting, switch collateral to your primary home, or use a DSCR cash-out instead.
- The property was recently listed. A property listed for sale, or listed within the past 60 days, is ineligible in Indiana, North Carolina, Pennsylvania, Tennessee, Texas, and Washington.
- The value comes in short. Lines at or below $500,000 ordinarily run automated valuation with no traditional appraisal, so an investment line is structurally always in that lane. A higher CLTV may trigger a secondary valuation, and a borrower can request a full appraisal at any time. If the valuation comes in light, the available line shrinks with it.
- Derogatory credit history. A bankruptcy needs 4 years of seasoning from discharge or dismissal. Foreclosure history on investment files follows a 7-year seasoning path, and a deed-in-lieu, pre-foreclosure, or short sale follows 4.
Using your primary home as collateral raises the ceiling, to as much as 90% CLTV at 720+ credit on a primary residence, but it puts the home at risk. The CFPB warns that falling behind on a HELOC can mean losing the home. That is a real cost, not a footnote.
Should You Use a HELOC or a DSCR Cash-Out?
A HELOC makes sense when the existing first mortgage is worth protecting, the amount you need is under the $500,000 ceiling, your personal income and credit carry the file, and you have a repayment plan. A DSCR cash-out refinance makes sense when the rental is already in an LLC, when the property’s income is the stronger file than your personal profile, or when you want a fixed-structure replacement loan. For a head-to-head on funding a down payment, see Lendmire’s piece Cash-Out Refinance vs HELOC for Funding Your Next Rental Down Payment. Investors weighing alternate documentation routes can read the piece Rental HELOC Without Tax Returns vs Bank Full Documentation.
The strongest files clear two tests: enough equity and enough rental coverage. Equity gets the line. Coverage gets the purchase loan. A larger down payment lowers the monthly obligation and can lift the DSCR on the new deal, but it never erases leverage caps, credit floors, reserve rules, or property eligibility. For the full structure of the purchase side, start with the complete DSCR loans guide.
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.
Key Terms Defined
HELOC: A revolving credit line secured by property, with a draw period followed by a repayment period.
CLTV: Combined loan-to-value, which adds all liens plus the full line limit and divides by property value.
Draw period: The stretch when you can borrow against the line, often with interest-only payments.
DSCR: Debt service coverage ratio, which divides a property’s monthly rent by its monthly principal, interest, taxes, insurance, and any HOA dues.
Source of funds: The documented origin of the money used for a down payment or reserves.
Lien position: Whether a loan sits first or second in line to be repaid from the collateral.
Frequently Asked Questions
Can I get a HELOC on a rental property?
Yes, through select lenders, with tighter terms than a primary-home line. On an investment property the network ceiling is 70% CLTV, the minimum credit score is 700, and lines run from $25,000 to $500,000. The rental must be titled in an individual’s name or a revocable living trust, subject to lender guidelines.
Does the rent help me qualify for the HELOC?
No. The line is reviewed on your personal income, debt-to-income, and credit. The rent matters on the later DSCR purchase loan, which reads the new property’s income against its monthly obligation. These are two separate approvals.
Can I keep the line undrawn until I find a deal?
Not on this structure. At least 75% of the line is drawn at closing, so most of the balance starts accruing interest right away. Plan to carry that cost, or size the line closer to what the deal needs.
Will the next lender accept HELOC money for my down payment?
It depends on the purchase lender. Each DSCR lender sets its own source-of-funds rules, and some want documentation of how the funds moved. Draw ahead of time, keep the money in a dedicated account, and confirm the lender’s position before you rely on it.
What if my rental is held in an LLC?
An LLC cannot hold title on these lines. You can re-deed the property to yourself or a revocable trust after checking with your existing lender and insurer, use your primary home as collateral, or use a DSCR cash-out refinance instead.
