The Quick Read: An investment property HELOC lets you borrow against the equity in a rental you already own, up to 70% combined loan-to-value (CLTV) and a $500,000 line. Underwriters size it on your credit, your debts, and your equity, not on the rent. Strong equity alone is not enough, because title, credit, and debt load all have to fit too.
- CLTV is the sizing tool. It adds every loan on the property, divides by value, and the total must stay at or under 70% on an investment property line.
- Credit sets a hard floor. A 700 score is the minimum on an investment line, and 720 buys no extra leverage.
- Title can break the deal. The property must sit in your name or a revocable living trust, not an LLC.
- Most of the line is drawn up front. At least 75% is drawn at closing, so this is not a free standby line.
- Rent coverage is not the test. That belongs to a DSCR loan, which is a different tool for a different job.
Lendmire is a broker. It arranges these lines through select wholesale partners, and every figure below is subject to lender guidelines and full file review. None of it is a commitment to lend.
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 Does Borrowing Power Mean for a Rental Owner?
Borrowing power is the total amount you can still borrow after every existing loan and every personal debt is counted. For a landlord, four things set it: equity, credit and debt load, the property itself, and how the property is titled.
Most investors only think about the first one. Equity is the starting point, but the other three can shrink the answer to zero.
A DSCR loan, short for debt service coverage ratio loan, works the opposite way. It checks whether the rent covers the property’s full monthly payment (principal, interest, taxes, insurance, and any HOA dues). A HELOC does not do that. A HELOC looks at you.
How Does an Investment Property HELOC Work?
An investment property HELOC is a revolving line secured by a lien on your rental. You draw what you need, pay interest only during the draw period, then repay principal and interest over a set term.
On the investment lines Lendmire places, the structure is a 5-year interest-only draw followed by a 25-year fully amortizing repayment. The price floats and never converts to fixed. At least 75% of the line is drawn at closing. The line can sit in first or second lien position.
That structure matches how the CFPB describes HELOCs: a draw period, then a repayment period, with variable pricing that moves payments over time. The FTC adds that you pay interest only on what you actually borrow. The 75% drawn at closing means the borrowed amount starts high on this product.
Line sizes run from $25,000 to $500,000 on an investment property. Lines above $500,000 exist only on primary residences. There is no higher investment tier.
One availability note. This HELOC product runs in Lendmire’s 16 full-service states, which is narrower than its 41-market DSCR footprint, including Washington, D.C. Bankrate notes that these lines are far less common than HELOCs on a primary home. Many large retail lenders simply do not offer them on rentals.
How Single-Family Rental Borrowing Power Gets Sized
The formula is simple: maximum line equals value times the allowed CLTV, minus every existing lien. Then the program limits cap the result.
Run the numbers with a round-number picture. Say a rental is valued at 100 units. The 70% CLTV ceiling allows 70 units of total debt. If the first mortgage is 50 units, the new line can be 20 units, not 70. The cap applies to the combined debt, not to the new line alone.
Here is how that headroom shrinks as the first mortgage grows. These are percentages of the property’s value on an investment line with a 70% CLTV ceiling:
| First mortgage (% of value) | Room for a new line |
|---|---|
| 0% (free and clear) | Up to 70% of value |
| 30% | Up to 40% of value |
| 50% | Up to 20% of value |
| 70% or more | None |
Two more limits apply. First, the dollar range: a high-value rental with little debt can hit the $500,000 cap before it hits 70%. Second, the $25,000 minimum: a thin slice of headroom may fall below it, which makes the line impractical.
Valuation is usually painless. Because an investment line caps at $500,000 and full appraisals begin only above that amount, these lines run on an automated valuation and commonly close with no traditional appraisal. A higher CLTV may call for a secondary valuation, and you can request a full appraisal if you want one.
What Underwriting Reviews, Step by Step
Underwriting is personal. The lender secures the line with your property but approves it based on you. Here is the sequence a file follows.
1. Value. An automated valuation sets the starting number for most investment lines.
2. CLTV test. All liens are added and divided by value. The total must be 70% or less.
3. Subtract existing liens. What remains is the usable headroom, capped at $500,000.
4. Credit review. The program minimum on an investment property is 700. The score model is single-bureau, and the report can be no more than 90 days old at closing. A bankruptcy needs 4 years of seasoning from discharge or dismissal. On investment files, a foreclosure needs 7 years, and a deed-in-lieu, pre-foreclosure, or short sale needs 4.
5. Debt-to-income (DTI) review. DTI is your monthly debts divided by your monthly income. It tops out at 50%, and the lender reviews your file on the interest-only payment calculated on the maximum draw, not just the amount you plan to use.
6. Title check. The property must be held by you individually or by an inter vivos revocable living trust. That is a trust you can change or cancel during your life.
7. Property check. The property type must be eligible (see the edge cases below).
Credit above 700 does not raise leverage. A 720 and a 700 both reach the same 70% ceiling. Credit above the floor buys eligibility, not extra room.
Where the Rule Breaks: Edge Cases
The general rule is “equity times 70%, minus liens.” These situations bend it.
An LLC holds the deed. This is the sharpest break for investors who hold rentals in entities. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title on this product. A rental already in an LLC needs a vesting change first, or a DSCR cash-out instead. DSCR loans can be held in an LLC, subject to program terms.
The first mortgage is already near the cap. If the first lien sits at or above 70% of value, headroom is zero. Credit and income cannot fix that.
The property type is off the menu. Single-family homes, PUDs, townhomes, and condominiums are eligible, including non-warrantable condos. Two-to-four unit properties are also eligible. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not offered.
You own many financed properties. A borrower is limited to three lines, with combined exposure capped at $2,000,000 on one wholesale program and $750,000 on the other. The higher cap belongs to the higher-leverage program, and the lower cap belongs to the longer-runway program. A borrower with more than 15 financed properties is not eligible.
The listing is active. A property listed for sale, or listed within the past 60 days, is ineligible in several states, including IN, NC, PA, TN, TX, and WA.
You hold a primary-residence line instead. Many investors skip a rental line and use a HELOC on their own home to fund the down payment on the next rental. That line is underwritten against the owner-occupied house, and a separate acquisition loan, often a DSCR loan, funds the rest. Lendmire’s rules for a HELOC on a single-family rental cover the investment-line side in more detail.
A funded line changes later refinancing. A drawn HELOC is a lien. If you later want a cash-out refinance, the lien affects how the new loan is sized and whether it must be paid off. Treatment varies by lender, so raise it early.
HELOC or DSCR Cash-Out?
The two tools answer different questions. A HELOC asks whether you can carry the debt. A DSCR cash-out asks whether the property can.
| Factor | Investment HELOC | DSCR cash-out |
|---|---|---|
| Underwritten on | You: credit, DTI, equity | Rent versus full payment |
| Max leverage | 70% CLTV | Around 75% LTV (70% on STR) |
| Title | Individual or revocable trust | LLC possible, per program |
| Structure | Variable, 5-yr draw, 25-yr repay | Typically 30-year fixed |
| Personal DTI impact | Yes | Generally no |
The DSCR side deserves a few honest notes. On a standard rental cash-out, leverage tops out around 75% LTV across most of the network, and about 6 months of seasoning is the common expectation. On short-term-rental collateral, cash-out is 70%. A coverage ratio of 1.00 is where many select programs start, and a separate select-lender path takes coverage below 1.00 with leverage and terms adjusted. Stronger coverage opens better pricing and leverage. Credit of 620 exists in parts of the network, most programs want around 660, and 700+ unlocks the strongest leverage tiers. Reserves vary by lender, leverage, and loan size, commonly around 6 months of PITIA, meaning principal, interest, taxes, insurance, and association dues.
Lendmire’s comparison of a HELOC versus a cash-out refinance on a rental goes deeper on that choice. Lendmire’s complete DSCR loans guide covers the full DSCR side.
Which Investor Fits Which Tool?
A HELOC fits an investor with strong personal credit, modest total debt, a rental held in their own name, and equity that clears the 70% test. Typically that is someone with one to a few rentals who wants flexible access to cash.
A DSCR cash-out fits an investor whose rentals sit in LLCs, who is near a DTI limit, or who wants a fixed payment. It can also suit someone with a larger portfolio, since the loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines.
Some investors use both. A HELOC supplies the down payment, and a DSCR loan finances the purchase. The lenders review each loan separately, so disclose the plan to both. In practice, the rent has to carry the new DSCR payment and your budget has to carry the HELOC payment.
Stress-Test Before You Draw
Passing underwriting is not the same as a safe deal. Test three things before you draw.
The variable payment. The line floats during the draw and during repayment. When interest-only ends after year five, the payment steps up because principal begins. The CFPB’s HELOC brochure explains that variable plans use an index plus a margin, and that some plans allow interest-only payments during the draw period.
The rent hit. Picture a rental that covers its debt at about 1.2x. Add the HELOC payment and a few months of vacancy, and that cushion can vanish.
The DSCR trap. Clearing 1.00 is not positive cash flow. DSCR compares rent to PITIA only. Repairs, vacancy, management, utilities, and capex sit outside the calculation, so budget for them separately.
The 75% draw at closing matters here too. You begin repayment on most of the line right away, so only draw what the deal can carry.
When not to use a rental HELOC: if the deal only works when everything goes right, if you cannot absorb a payment increase, or if the money has no clear purpose. 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.

Frequently Asked Questions
Can I get a HELOC on a rental I already own?
Yes, if the rental is eligible and you meet the credit, DTI, and CLTV tests. On an investment property, the line caps at 70% CLTV and $500,000, with a 700 credit minimum. Availability depends on the lender and the state.
Can my LLC hold the property?
No. Title must sit with you individually or in your revocable living trust. A property already deeded to an LLC needs a vesting change, or a DSCR cash-out may fit better, subject to program terms.
Does a higher credit score raise how much I can borrow?
Not on an investment line. A 720 score and a 700 score both reach 70% CLTV. The score only needs to clear the 700 floor.
Will a new line affect my next loan?
Yes. A funded line adds a lien and a personal debt, which the next lender will see. It can affect DTI on another personal-income loan and the sizing of a later cash-out refinance. DSCR purchase loans look mainly at the new property’s rent, but lenders still review the full file.
Is a HELOC a good way to buy a rental?
It can supply the down payment. The purchase loan, often a DSCR loan, is a separate transaction. Keep funding sources documented and disclose the plan to both lenders.
