The Quick Read: An investment property HELOC is a floating-price credit line secured by equity, and it pays off only when the money you invest earns more than the line costs, the draw timing fits your plan, and the title sits in your name or a revocable trust.
- On an investment property, lines in Lendmire’s wholesale network reach 70% CLTV (combined loan-to-value) with a 700 minimum credit score, up to $500,000.
- Most of the line is drawn at closing, so the carrying cost starts on day one.
- Investment lines run a 5-year interest-only draw, then a 25-year repayment period. Pricing floats the whole way.
- The real test is simple: does the net return on the new use clearly beat what the line costs you?
- LLCs cannot hold title on these lines. Owners with entity-titled rentals usually look at a DSCR cash-out refinance instead.
What an Investment Property HELOC Actually Is
A home equity line of credit (HELOC) is a revolving line secured by the equity in a property. On an investment property, the line sits behind or alongside your existing mortgage and lets you draw cash against the equity.
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.
Across the wholesale network Lendmire works with, the investment version has a tight box. It is a standalone line in first or second lien position. Sizes run from $25,000 to $500,000. The ceiling is 70% CLTV on an investment property, and the minimum credit score is 700. Both the 720 and 700 credit tiers reach the same 70% ceiling. So a higher score buys eligibility, not extra leverage.
CLTV counts every loan against the property, including the line itself. A rental with a first mortgage already sitting at 55% of value leaves room for a line of up to about 15% of value. That is the entire math. Value times 70%, minus what you owe, caps the line.
Lendmire is a broker. It arranges these lines through select wholesale partners and is never the lender. Every figure here is subject to lender guidelines and full file review. This line is available only in Lendmire’s 16 full-service states, which is narrower than its 41-market DSCR footprint, including Washington, D.C.
Because the line caps at $500,000, valuation ordinarily runs on an automated model instead of a traditional appraisal. A borrower can still request a full appraisal.
Which Property Should Secure the Line?
You can borrow against a rental or against your own home. Each choice moves the risk to a different place.
| Factor | Line on primary home | Line on a rental |
|---|---|---|
| Property at risk | Your residence | The rental itself |
| Top CLTV | 90%, only at 720+ credit | 70% (700+ credit) |
| Draw structure | 3-year or 5-year draw | 5-year draw only |
| Title | Individual or revocable trust | Individual or revocable trust |
A line on your primary home often gives more room. It also puts your residence behind an investment you hope will perform. A line on the rental keeps the exposure contained to the rental. The tradeoff is the lower 70% CLTV ceiling and fewer lenders willing to write it.
Key Terms Defined
CLTV: Combined loan-to-value is the total of all loans against a property divided by its value.
Draw period: This is the stretch when you can pull money from the line and pay interest only.
Repayment period: This is the stretch after the draw period ends, when you can no longer draw and the balance amortizes.
DTI: Debt-to-income is your monthly debt payments divided by your monthly income.
DSCR: Debt service coverage ratio is a property’s monthly rent divided by its monthly obligation, including principal, interest, taxes, insurance and any HOA dues.
PITIA: This is principal, interest, taxes, insurance and association dues, the full monthly obligation on a property.
Vesting: This is the legal form in which title to the property is held, such as an individual, a trust or an LLC.
How Underwriting Treats the Line, Step by Step
An equity line is underwritten on you, not on the rental. A DSCR loan works the other way. Here is the sequence a lender in the network follows.
1. Credit. The lender pulls a single-bureau score keyed to the primary wage earner. Investment lines floor at 700. The report cannot be more than 90 days old at closing, and there are no rescores.
2. DTI. The maximum is 50%. The lender reviews your file on the interest-only payment calculated on the maximum draw, not the amount you plan to use.
3. Existing debt and combined leverage. Your first mortgage and any other liens count against the 70% CLTV ceiling.
4. Valuation. An automated valuation is the usual route at this size.
5. Title. The property must be held by you individually or by an inter vivos revocable living trust.
6. Exposure. A borrower is limited to three lines. A borrower owning more than 15 financed properties is not eligible.
Rent matters little here. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. A HELOC does not work that way. The lender looks at your personal profile, and the more financed properties you carry, the more your personal DTI becomes the bottleneck.
Property type matters too. Single-family, 2-4 units, PUDs, townhomes and condos, including non-warrantable condos, are eligible. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use and agricultural-zoned properties are not.
Draw and Repayment: What the Calendar Does to Your Plan
Equity lines have two phases, and the second one catches people off guard. During the draw period you borrow and pay interest. After it ends, you can no longer draw, and the balance moves into repayment. The CFPB’s consumer guidance on HELOCs notes that lenders often set repayment schedules over ten or 20 years. It also notes that these lines usually float, so payments can change.
The CFPB’s HELOC brochure adds a detail that matters for investors. Some plans allow interest-only payments during the draw, so nothing goes toward principal. With floating pricing, the payment can change even if you draw nothing more.
In the network, an investment line runs 5 years interest-only, then 25 years of full amortization. Pricing floats across both phases and never converts to fixed. Pricing and available terms vary by lender, borrower profile, property type, and full underwriting review.
The practical lesson is timing. If you plan to hold the investment past year five, your payment will step up when amortization begins. If your plan pays off sooner, the interest-only phase is your friend. Match the payback horizon of the investment to the calendar of the line.
Ways to Invest the Funds, Compared
Different uses of the money produce very different results. This table ranks them by where the return comes from and what can go wrong.
| Use of funds | Return source | Payback timing | Key risk |
|---|---|---|---|
| Down payment on a rental | Rent and appreciation | Slow, years | Two payments on one deal |
| Renovation of a rental | Higher rent, value | Medium | Cost overruns, vacancy |
| Bridge before a refinance | Refinance proceeds | Short, fixed window | Refinance falls through |
| Securities | Market gains | Uncertain | Losses while debt remains |
| Business funding | Business profit | Uncertain | Illiquid, personal exposure |
| Paying down other debt | Saved interest | Immediate | No new income created |
Down payment on a rental. This is the most common use. Purchases through the network typically land at 75%-80% LTV on a purchase, which means 20%-25% down. Select high-leverage programs reach 85% LTV on a purchase, with 15% down and roughly a 700+ score. The new loan keeps its own leverage, reserve and source-of-funds rules. Borrowed down-payment money is often allowed, but it must be documented and still leave enough reserves, which commonly run around six months of PITIA.
Draw early enough that a large deposit does not muddy your bank statements. Using the whole line on one down payment also leaves little cash cushion for the next deal.
Renovation. Improvements may support a higher appraised value, depending on comps and underwriter review. They can also lift rent. The payoff comes later than the spending, and the line charges you in between.
Bridge to a refinance. Some investors draw on the line, rehab a property, then refinance to pay the line off. This works only if the refinance lands on time. A DSCR cash-out on a standard rental tops out around 75% LTV, and about six months of seasoning is the common expectation. If the property does not appraise or season as planned, you are stuck carrying the line. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.
Securities and business funding. These uses can work, but your repayment floats while the return is not guaranteed. They also create concentration risk, because your home or rental is pledged against something that can lose value.
Paying down other debt. This one creates no new income. It only changes the cost. It can still make sense when the line replaces debt that costs more.
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.
The Breakeven Test (With a Stress Case)
Run one comparison before you draw. Estimate the annual net return the new use should produce after vacancy, repairs, management and utilities. Then estimate the annual carrying cost of the line on the amount you will actually draw. If the first number is not clearly larger than the second, skip the draw.
Here is an illustrative case, with every figure a modeled assumption rather than market data. Say you draw against equity to cover the down payment on a rental. The new DSCR loan shows coverage near 1.20x. That looks comfortable.
Look closer. The 1.20x measures only the rental’s rent against its own payment. It does not include the payment on your HELOC. Clearing 1.00 on a DSCR loan also does not mean positive cash flow. Repairs, vacancy, management, utilities and capital expenses all sit outside that ratio.
Now stress it. Floating pricing on the line moves up, the rental sits vacant for two months, or a roof fails. Your fixed leases cannot adjust, but the line can. A deal that looked healthy at 1.20x can leave you paying the line out of pocket.
This one is a genuine judgment call. A purchase with deep coverage and a short payback plan can handle the stress. A thin-coverage deal funded by a floating line is a real risk.
On the DSCR side, 1.00 is where many select programs start. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Stronger coverage generally opens better pricing and leverage.
Where the General Rule Breaks
Entity-titled rentals. LLCs, corporations, partnerships, and irrevocable, blind or land trusts cannot hold title on these lines. A property already deeded to an LLC needs a vesting change or a different structure. The usual alternative is a DSCR cash-out refinance, subject to lender program eligibility.
Large portfolios. Past 15 financed properties, a borrower is not eligible. Well before that, personal DTI becomes the constraint. This is where DSCR products usually take over, because they look at each property’s income.
Thin lender supply. Rental-secured lines are a narrower product than primary-home lines. The White Coat Investor notes that fewer lenders offer them and large banks tend to be stricter. Expect fewer options and tighter terms.
Someone else’s equity. A parent’s or relative’s HELOC is not your equity. Money from it is generally treated as a gift and needs to be documented that way.
Mixed use. If you split the draw between a rental and personal spending, keep the amounts separate. A dedicated account for the draw makes records far easier.
Short horizons. Bridge strategies assume a refinance that arrives on schedule. Plan an exit before you draw: pay it down, refinance it, or stop drawing.
Lease rules at scale. Owners with five or more rentals face extra questions on documentation. Lendmire’s look at how lease rules apply to HELOCs for five-plus rental owners walks through them.
HELOC or DSCR Cash-Out Refinance?
A HELOC adds a second payment to your personal DTI. A DSCR cash-out replaces your first loan and leans on rental coverage. The choice usually turns on four things: title, your existing first-mortgage terms, how much cash you need, and your personal DTI.
| Factor | Investment HELOC | DSCR cash-out |
|---|---|---|
| Underwritten on | Personal credit and DTI | Property rent vs payment |
| Top leverage | 70% CLTV, investment | About 75% LTV, standard rental |
| Short-term rental cash-out | Not a separate tier | 70% LTV, short-term rental |
| Title | Individual or revocable trust | Entity title may fit |
| Pricing | Floats throughout | 30-year fixed is the spine |
DSCR cash-out loans typically reach up to $3,000,000 on standard programs, with smaller balances available through select lenders. Most programs want a score around 660, though a 620 floor exists in parts of the network. Extended terms and interest-only periods are available through select lenders. The complete DSCR loans guide explains how the program is built.
A cash-out refinance also resets your existing first mortgage. If that mortgage carries terms you want to keep, a HELOC may be the better fit.
Who It Fits and Who Should Skip It
A HELOC tends to fit when:
- You hold title individually or in a revocable trust.
- Your credit is 700 or better and your DTI sits at or under 50%.
- You have a short, defined payback plan.
- The new use clearly beats the carrying cost.
Skip it, or look at a DSCR cash-out instead, when:
- Your rentals are titled in LLCs.
- You own many financed properties and personal DTI is tight.
- Your plan depends on a refinance that is not guaranteed to happen.
- You would use the whole line and leave no cash cushion.
How the Process Works
1. Pick the collateral: your home or a rental.
2. Check your combined leverage against the 70% CLTV ceiling.
3. Confirm your title is individual or a revocable trust.
4. Gather credit, income and lien documents for the lender’s review.
5. Plan for most of the line to be drawn at closing.
6. Set the exit before you draw.
Frequently Asked Questions
Can I use an investment property HELOC for the down payment on another rental?
Often yes, but the new loan keeps its own leverage, reserve and source-of-funds rules. Borrowed funds should be documented and drawn early enough to season in your statements. Qualification on the new loan stays subject to lender guidelines.
Does the HELOC payment show up in my DSCR on the new loan?
No. The DSCR compares the new property’s rent to its own payment. Your HELOC payment is still a real cost outside that ratio, so include it in your own cash-flow math.
Can my LLC open an investment HELOC?
No. LLCs, corporations and partnerships cannot hold title on these lines. A DSCR cash-out refinance is the usual path for entity-titled rentals, subject to program terms.
How much of the line do I have to draw?
At least 75% of the line is drawn at closing. Plan the size of the line around that, because interest starts on the drawn balance immediately.
What credit score do I need for a HELOC on a rental?
A 700 minimum applies on investment lines. Scores at 720 and 700 both reach the same 70% CLTV ceiling.
