The Quick Read: A small group of lenders will open an equity line secured by a rental you already own, and that line works as down-payment money for the next purchase, not as the purchase loan itself. Because the product is uncommon, a broker that works with several wholesale lenders is one practical way to find a fit.
- On an investment property, the network ceiling is 70% combined loan-to-value (CLTV), with a minimum credit score of 700 and a maximum line of $500,000.
- The line is underwritten on you (credit, debt-to-income, equity), not on the rent, so title and DTI decide more files than rental income does.
- LLC-held rentals generally cannot take this line. Title must sit with you personally or in a revocable living trust.
- The purchase itself still needs its own financing or a cash offer, and a rent-based DSCR loan is the usual exit.
What an Investment Property HELOC Actually Is
An investment property HELOC is a revolving line of credit secured by a rental you own. You draw against it, repay, and draw again within set limits. The collateral is the rental, not your home.
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.
Two features separate it from a standard mortgage. First, it leaves your existing first mortgage in place and sits behind it as a second lien. Some wholesale programs also write it in first position, which suits a free-and-clear rental. Second, the pricing floats during both the draw period and the repayment period on the program described here, and it does not convert to a fixed structure.
Experian describes the product as possible but less common than a line on a primary home. It can fund renovations, repairs, or another real estate investment. That scarcity is the real answer to the question behind the title. Banks that offer it exist, but a single branch visit rarely finds one.
Why Few Banks Write This Line
Lenders treat a rental as riskier collateral than an owner-occupied home. A borrower under financial stress tends to protect the home first. A tenant can also stop paying, which squeezes the owner’s cash.
Investors describe the same pattern. A BiggerPockets thread on HELOCs for rentals shows borrowers being told that a bank would write a line only on a primary residence. Another BiggerPockets discussion points investors toward small local banks and credit unions as the more likely places to find one.
Lenders fall into three rough groups, and the stance on rental collateral differs:
| Lender type | Typical stance on rental collateral | How to approach |
|---|---|---|
| Large retail banks | Often primary home only | Ask the desk directly before applying |
| Local banks and credit unions | Sometimes, with tight limits | Ask about title, property count, lien position |
| Wholesale lenders via a broker | Written under set program terms | Match the file to the program first |
None of this tells you which lender is right. The best fit depends on your credit profile, the property type, how much equity you hold, and how the property is titled.
How Underwriting Treats the Line, Step by Step
Underwriting follows a fixed sequence, and a file can stall at any step. Knowing the order helps you screen yourself before you apply.
Step 1: Occupancy and collateral. The property is an investment property, so the investment table applies. Credit above 700 buys eligibility, not extra leverage, and 700 is a hard floor with no tier beneath it.
Step 2: Title. The property must be held by you as an individual or by a revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title on the line. This is the sharpest difference from a DSCR loan. A rental already deeded to an LLC needs a vesting change first, or a DSCR cash-out refinance instead. BiggerPockets investors report the same wall, since most banks will not issue a HELOC to an LLC.
Step 3: Equity math. CLTV is all liens on the property divided by its value. The room you have is the gap between your first mortgage and the 70% ceiling. The worked example below shows how this plays out.
Step 4: Borrower qualification. Credit and debt-to-income carry the file. DTI tops out at 50%, and the lender reviews your file on the interest-only payment calculated on the maximum draw, not on the amount you plan to take. The credit report must be no more than 90 days old at closing, and the score model is a single-bureau score keyed to the primary wage earner.
Step 5: Documents and valuation. Benzinga lists proof of income, tax returns, rental agreements, and proof of insurance as the usual package. On valuation, a full appraisal is required on every line above $500,000, while an investment line is capped at $500,000. So an investment line sits in the automated-valuation lane and commonly closes without a traditional appraisal. You can still request a full appraisal.
Step 6: Exposure checks. Two separate limits apply here. One is a cap of three lines per borrower. The other is a property count: anyone owning more than 15 financed properties is not eligible. Listing status matters too. A property listed for sale, or listed within the past 60 days, is ineligible in Indiana, North Carolina, Pennsylvania, Tennessee, Texas, and Washington.
The Structure and Limits
The investment line runs a 5-year interest-only draw followed by a 25-year fully amortizing repayment period. Unlike a typical revolving line, a set share is funded up front: at least 75% of the line is drawn at closing. Any later draw after closing typically carries a $1,000 minimum on programs that state one.
Line size runs from $25,000 up to $750,000 across the network. On an investment property, the cap is $500,000. Lines above that figure are for primary residences only, and they carry a 75% CLTV ceiling and a full appraisal.
Eligible property types include single-family homes, two- to four-unit properties, PUDs, townhomes, and condominiums, including non-warrantable condos. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not offered.
Credit history rules matter for borrowers with past trouble. A bankruptcy needs four years of seasoning from discharge or dismissal. On investment files, a foreclosure seasons for seven years, and a deed-in-lieu, pre-foreclosure, or short sale seasons for four.
A Worked Equity Example
Take a rental with a first mortgage equal to 50% of its value. At the 70% CLTV ceiling, the available room is 20 points of that value. At least 75% of the line is drawn at closing, so a draw of at least 15 points of value is built into the structure.
That 20-point figure is measured against the old rental, not the new one. A $500,000 maximum line also applies to the investment product.
Compare that with the market picture. Experian reports that investment-property lines in the broader market are typically capped around 80% loan-to-value, with at least 20% equity left after a full draw. That is a market-wide figure. On this network, the investment ceiling is 70% CLTV, and no tier sits above it.
The comparison matters for planning. Do not size a purchase around a market-wide cap that the network does not offer.
Primary-Home Line or Rental Line?
Many investors skip the rental as collateral altogether and borrow against their own home instead. Both routes work, and each carries a different risk.
| Factor | Line on primary home | Line on the rental |
|---|---|---|
| Network ceiling | Up to 90% CLTV, only at 720+ credit | 70% CLTV, 700+ credit |
| Maximum line | Up to $750,000 | $500,000 |
| What is at risk | Your home | The rental |
| Lender pool | Larger | Smaller |
The leverage gap is real, but so is the risk. A line secured by your home puts your residence behind an investment decision. A line secured by the rental keeps the exposure on the asset that produced the equity. Benzinga notes that missed payments put the secured property at risk of foreclosure, and the line adds to your overall debt load.
The investor who values keeping the home clear may choose the rental line despite the lower ceiling. The investor with a strong credit profile and a lot of home equity may prefer the primary-home line for its higher ceiling and larger pool. Neither is wrong.
Sequencing the Purchase: Line, Purchase Loan, Exit
A HELOC does not buy a rental by itself. It provides cash, and the purchase still needs a closing structure. The sequence usually looks like this:
1. Open the line first. It is a separate approval from the purchase loan, so do it before you write offers.
2. Draw into your own account. Keep the draw separate from personal spending so the money stays traceable.
3. Buy the next rental. Use the cash as the down payment, or as a full cash offer where that fits.
4. Place long-term financing on the new property. A DSCR purchase or refinance typically lands at 75%-80% LTV on a purchase, with select high-leverage programs reaching 85% at roughly a 700+ score. A cash-out refinance tops out around 75% LTV across most of the network, with about six months of seasoning commonly expected.
5. Repay the line. Use cash flow, a refinance, or a sale.
Two approvals means two sets of risk. If the second approval fails, you hold a drawn line and a property you may not be able to finance. Clearing both tests is the goal: enough equity for the line and enough rental coverage for the exit loan.
The DSCR test compares monthly rent to the full monthly obligation: principal, interest, taxes, insurance, and any HOA dues. A coverage of 1.00 is where many select programs start, and stronger ratios open better terms. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Clearing 1.00 does not mean positive cash flow, because repairs, vacancy, management, utilities, and capital expenses sit outside the calculation.

Where the General Rule Breaks
The 70% ceiling and the title rule hold in most files. A handful of situations push the answer elsewhere.
LLC-held portfolios. The line does not fit entity-owned rentals. BiggerPockets posters describe workarounds such as temporary title transfers. A transfer can raise due-on-sale, title-insurance, and liability questions, so it is worth a conversation with counsel before trying it.
Larger portfolios. The DTI wall arrives early for leveraged investors. A line is underwritten on the borrower, and the 50% DTI ceiling can bind long before equity runs out. Some lenders also cap the number of other properties. One BiggerPockets thread mentions a three-property limit at one lender. On this network, the property count is separate from the three-line limit per borrower, and ineligibility begins only above 15 financed properties.
High-value rentals. On an expensive property, a cash-out refinance can pull more than the line allows.
Rentals with an existing mortgage. Some desks decline these, and one BiggerPockets poster reported that no bank they called would write a line behind an existing mortgage. Wholesale programs do write second-lien and first-lien structures, which is why the lender pool matters.
A property you cannot scale on. Equity in one rental cannot be pulled through a line secured by another. Each line is tied to its own collateral, so the product is a weak engine for scaling a large portfolio.
Ineligible collateral. Manufactured homes, log homes, barndominiums, co-ops, and condotels are not offered. If your equity sits in one of those property types, this product will not reach it.
When a Different Product Fits Better
A DSCR cash-out refinance replaces the first mortgage with a new loan sized off the property’s rent. It qualifies primarily on property-level rental income covering the payment, subject to lender guidelines, and it can be held in an LLC, subject to lender program eligibility. A cash-out tops out around 75% LTV on most standard rentals.
If the first mortgage is small, the line leaves it alone and costs less to set up. If the first mortgage carries a poor structure, or the property sits in an LLC, a cash-out is often cleaner.
Tax treatment can depend on how the funds are used and how the property is held. Keep clear records and speak with a qualified tax professional before relying on any deduction.
Questions to Ask Before You Apply
These questions screen a lender in a few minutes:
- Do you write lines on non-owner-occupied property?
- Will you lend behind my existing first mortgage?
- Can title sit in my revocable living trust?
- What is the maximum CLTV, and what is the maximum line?
- Do you cap the number of financed properties?
- Does the valuation require a full appraisal, or an automated model?
- What are the draw and repayment periods, and does pricing ever convert to fixed?
A broker shops those answers across several wholesale lenders at once. It then matches the file to the program that fits, instead of leaving you to call banks one at a time.
Key Terms Defined
HELOC: A revolving line of credit secured by property, with a draw period followed by a repayment period.
CLTV: Combined loan-to-value, which is all liens on the property divided by its value.
DSCR: Debt service coverage ratio, which compares a rental’s monthly rent to its full monthly obligation.
Draw period: The stretch when you can borrow against the line, on this network five years for an investment line.
Second lien: A loan that sits behind your existing first mortgage in repayment priority.
Automated valuation: A model-based value estimate used in place of a traditional appraisal.
Frequently Asked Questions
Can an LLC-owned rental take a HELOC?
Generally not. On this network, title must sit with you as an individual or in a revocable living trust, and LLCs, corporations, and partnerships cannot hold title on the line. If your rental already sits in an LLC, you would need a vesting change or a DSCR cash-out refinance instead, subject to lender program requirements.
How much can I borrow against a rental?
The ceiling on an investment property is 70% CLTV, with a $500,000 maximum line and a 700 minimum credit score. Your available room is the gap between your first mortgage and that ceiling. Every figure is subject to lender guidelines and full file review.
Do I need an appraisal?
Usually not. Because an investment line caps at $500,000 and full appraisals start only above $500,000, the line commonly runs on automated valuation. A higher CLTV may call for a secondary valuation, and you can request a full appraisal at any time.
Does the line replace a DSCR loan?
No, they do different jobs. The line is underwritten on you and funds the down payment. A DSCR loan is reviewed primarily on property-level rental income covering the payment, and it usually serves as the purchase loan or the exit that repays the line.
Where is the investment HELOC available?
Lendmire’s HELOC placements run in 16 full-service states: AL, CA, CO, FL, GA, IN, MI, MT, NM, NC, OH, PA, TN, TX, VA, and WA. That is narrower than Lendmire’s DSCR investor-loan footprint across 41 markets, including Washington, D.C.
