The Quick Read: A home equity line of credit (HELOC) lets you borrow against equity you already own and use the cash for the down payment and closing costs on a rental.
- On Lendmire’s wholesale network, a line secured by an investment property tops out at 70% combined loan-to-value (CLTV) with a 700 minimum credit score, and the maximum line is $500,000.
- A line secured by your primary residence can reach 90% CLTV, but only at a 720 or better credit profile.
- Investment lines require at least 75% of the line to be drawn at closing, so they are not an idle safety net.
- The purchase lender decides whether borrowed money counts as your down payment, so ask it before you go under contract.
- A DSCR loan measures the rental’s rent against its own payment, and the HELOC payment still has to come out of your pocket. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
What Is an Investment Property HELOC?
An investment property HELOC is a revolving credit line secured by real estate and used to fund a rental purchase. You borrow, repay, and borrow again within a limit, much like a credit card backed by a lien on your property.
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.
Most investors mean one of two things by the phrase. The first route is a line on your primary residence, with the proceeds going toward a down payment on a new rental. The second route is a line secured by a rental you already own. A rental real estate guide calls the primary-residence route the more common of the two, and it says rental-secured lines come from fewer lenders with stricter requirements.
That scarcity is real. NerdWallet explains that lenders see higher default risk on rentals, so you have fewer lenders to choose from and can borrow less than against a primary home. Select wholesale programs, including some non-QM ones, exist to fill that gap.
Here is the part that confuses new investors. The HELOC never buys the rental by itself. It supplies cash. A purchase loan on the new property, such as a DSCR loan, supplies the financing. If you want the full picture of that second loan, the complete DSCR loans guide covers it from the ground up.
How the Money Flows, Step by Step
The seven steps below each involve a different lender or a different test, which is why the order matters.
1. Qualify the line. The HELOC lender reviews you and the collateral. On this network, that means credit, a debt-to-income (DTI) ratio capped at 50%, and the equity in the property securing the line.
2. Measure the equity. The lender adds your existing first mortgage balance to the new line and divides by the property’s value. That is CLTV. The result has to stay under the program ceiling.
3. Value the property. On an investment line, which cannot exceed $500,000, valuation is automated and commonly runs with no traditional appraisal. You can request a full appraisal if you want one.
4. Draw the cash. On this network, at least 75% of the line is drawn at closing. Plan around that, because you start carrying that balance immediately.
5. Keep a clean paper trail. Move the draw into a dedicated account and wire it to title from there. Purchase lenders ask where the down payment came from, and a straight line from the HELOC draw to the closing table answers the question.
6. Close the purchase loan. The purchase lender reviews the rental, your credit, your reserves, and the source of your funds.
7. Plan the exit. A real estate investor blog frames the line as short-term bridge financing that needs a named payoff source, ideally within a window of about 12 to 24 months. Common payoffs are rent and savings, a cash-out refinance, or a sale.
The step order undercuts a popular tip. A common suggestion is to open the line before you need it. On a primary-residence line that can work. On an investment line, the 75% draw requirement means you will be paying on most of it from day one, so open it when you have a deal in sight.
How Much Can You Borrow on This Network?
Two ceilings apply on Lendmire’s network, depending on how the property is used. Investment lines stop at 70% CLTV, while primary-residence lines can reach 90% CLTV, but only at a 720 or better credit profile. Both are subject to lender guidelines and full file review.
Experian reports a typical investment-property HELOC cap of 80% loan-to-value across the broader market. That is a market-wide statistic. The investment ceiling on this network is 70% CLTV.
| Factor | Line on a rental | Line on your primary home |
|---|---|---|
| Max CLTV | 70% | Up to 90% at 720+ (75% above $500,000) |
| Minimum credit | 700 | 600 floor; varies by tier |
| Line size | Up to $500,000 | Up to $750,000 |
| Draw structure | 5-year draw, 25-year repayment | 3-year or 5-year draw options |
| Valuation | Automated, usually no appraisal | Full appraisal above $500,000 |
A few details sit behind that table. On an investment line, a 720 score and a 700 score reach the same 70% CLTV, so credit above 700 buys eligibility rather than extra leverage. The primary-residence credit figures depend on the tier: 600 is the program floor, 720 is required for the 90% CLTV ceiling, and a line above $500,000 needs at least a 700 profile (720 on the longer-runway structure). That larger line caps at 75% CLTV and requires a full appraisal. Pricing on the lines in both programs floats through the draw and repayment periods.
The network places lines through two wholesale programs, and this article calls them the higher-leverage program and the longer-runway program. They differ in a few rules, such as how much combined exposure one borrower can carry, and each figure applies within its own program’s terms.
How Does the Purchase Lender Treat Borrowed Down Payment Money?
The purchase lender decides, and lenders differ. Many investors fund the down payment on a rental with a HELOC or a second mortgage. Some purchase lenders accept documented HELOC proceeds, while others cap the borrowed share or want some of your own cash in the deal. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.
Here is how the purchase side typically works across our wholesale network. Most DSCR purchase files land at 75% to 80% LTV, which means 20% to 25% down. Select programs reach 85% LTV with roughly a 700 or better score. The credit floor sits at 620 in parts of the network, most programs want around 660, and 700 or better unlocks the strongest leverage tiers.
DSCR itself is simple. The lender divides the rental’s monthly rent by the monthly principal, interest, taxes, insurance, and any HOA dues on the new loan. A DSCR 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.
A DSCR loan generally qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. That is why the HELOC payment may sit outside the ratio on the new property. It does not sit outside your budget. Some conventional-style reviews also count a HELOC payment in your DTI, so ask which test applies before you draw.
Reserves are the next trap. Reserves are liquid funds the lender wants you to keep after closing. They commonly run around 6 months of PITIA (principal, interest, taxes, insurance, and HOA dues), and they vary by lender, leverage, loan size, and transaction type. Borrowed money often cannot satisfy that requirement, so plan to hold reserves in your own cash.
A bigger down payment lowers the new loan’s payment and can lift the DSCR. It never erases leverage caps, credit floors, reserve rules, or property eligibility. The strongest files clear both tests, with enough equity and enough rental coverage.
What Does a Worked Example Look Like?
Run the percentages on this scenario, with every input a modeled assumption. Say you own a primary residence with a first mortgage that uses about 50% of its value. Your credit profile is 740. At the 90% CLTV ceiling for a primary-residence line at 720 or better, up to 40 points of the home’s value would be available to borrow, though a line above $500,000 caps at 75% CLTV, so the usable amount depends on the home’s value. Borrowing to the limit is risky, because a line that large leaves no cushion if values slip.
Now say you buy a duplex on a DSCR purchase loan at 75% LTV. Your down payment is 25% of the price, plus closing costs. If the HELOC funds all of it, you have financed close to 100% of the deal. The new loan clears roughly 1.2x on rent coverage, which looks comfortable on paper. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.
That 1.2x measures the purchase loan only. Add the HELOC payment on top, plus vacancy, repairs, management, and utilities, and the monthly picture can turn thin or negative. Clearing 1.00 on a DSCR is not the same as positive cash flow. Those operating costs sit outside the calculation.
Now compare it with a smaller draw. If the HELOC covers only part of the down payment and you bring the rest from savings, you carry less debt and keep more reserves. That is usually the safer shape, and it is also the shape a purchase lender is more likely to accept.
Where the General Rule Breaks
The standard path is a line on your primary home, a DSCR purchase loan, and a payoff plan. These edge cases bend it.
Title in an LLC. An investment-property line on this network 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. A rental already deeded to an LLC needs a vesting change, or a DSCR cash-out refinance instead. The DSCR loan itself can be made to an LLC, subject to program terms.
Property type. The line allows single-family homes, 2-4 units, PUDs, townhomes, and condominiums, including non-warrantable ones. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not offered. Manufactured homes, log homes, and barndominiums are also not offered on the DSCR side.
Exposure limits. A borrower is limited to three lines. Combined exposure caps at $2,000,000 on the higher-leverage program and $750,000 on the longer-runway program. A borrower owning more than 15 financed properties is not eligible.
Credit history. 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.
Listed properties. In some states, a property that is listed for sale, or was listed within the past 60 days, is ineligible. State overlays also change the ceiling on some primary-residence lines, so a few borrowers see a lower cap than the headline tier.
Availability. Lendmire arranges these standalone lines in 16 states only: AL, CA, CO, FL, GA, IN, MI, MT, NM, NC, OH, PA, TN, TX, VA, and WA. That is narrower than the 41-market DSCR footprint.
Falling values. The CFPB’s HELOC booklet says a lender may reduce your line if your home’s value falls. It also says you generally must repay the line in full if you sell the home. If a rent drop and a value drop arrive together, you can lose access to the cash right when you need it.
Collateral risk. A primary-residence line puts your home behind the rental purchase. If the rental underperforms, the lender looks to the house you live in.
HELOC, Cash-Out Refinance, or Cash?
A HELOC leaves your existing first mortgage alone. A cash-out refinance replaces it. Which fits depends on the equity you hold, the loan you already have, and how long you have owned the property.
A DSCR cash-out refinance on a rental you already own tops out around 75% LTV on standard rentals across most of the network. On short-term-rental collateral, the cash-out ceiling is 70%. About 6 months of seasoning is the common expectation. It is underwritten on the property’s rent rather than your personal income documents, subject to lender guidelines.
| Funding route | Collateral at risk | Main advantage | Main drawback |
|---|---|---|---|
| HELOC on primary home | Your residence | Keeps the first mortgage | Payment sits outside DSCR |
| HELOC on a rental | That rental | Home stays unencumbered | Fewer lenders; title limits |
| DSCR cash-out refinance | The refinanced rental | Underwritten on rent | Replaces the existing loan |
| Your own cash | None | Simplest file | Ties up liquidity |
Is This the Right Move for You?
The honest answer is that it fits a narrow group. It works best when you have real equity, a 700-plus credit profile, a purchase lender that accepts documented HELOC funds, and a rental that covers both payments with room to spare.
Skip it, or shrink the draw, if any of these describe you:
- Your equity is thin once the first mortgage is counted.
- Your rental sits in an LLC and the line needs individual or revocable-trust title.
- You have no reserves outside the borrowed funds.
- You have no named payoff plan for the line.
Before you apply, run a short checklist. Ask the purchase lender in writing whether HELOC proceeds count as a down payment. Confirm which payments feed any DTI test. Stress-test the combined payments against a vacancy. Set up the dedicated account. Decide your exit before you draw.
Key Terms Defined
HELOC: A revolving credit line secured by real estate that you can borrow against, repay, and borrow again within a limit.
CLTV (combined loan-to-value): Your first mortgage balance plus the new line, divided by the property’s value.
Draw period: The stretch when you can borrow from the line, usually with interest-only payments. On an investment line here, it runs 5 years.
Repayment period: The stretch after the draw period, when the balance amortizes. On an investment line here, it runs 25 years.
DSCR (debt service coverage ratio): Monthly rent divided by the monthly PITIA on the loan.
PITIA: Principal, interest, taxes, insurance, and any association dues.
Reserves: Liquid funds a lender wants you to keep after closing, often counted in months of PITIA.
Lien position: Whether a loan stands first or second in line for repayment if the property is sold. The standalone line here can sit in first or second position.
Frequently Asked Questions
Can a HELOC cover the whole price of a rental?
Usually not. A HELOC supplies cash, and the new property still needs a purchase loan. On a DSCR purchase, most files sit at 75% to 80% LTV, so the line typically covers the down payment and closing costs. Even then, the purchase lender sets the rules on borrowed funds, reserves, and credit, so a full draw can leave the file short.
What is the maximum CLTV on an investment property HELOC?
On Lendmire’s network, an investment-property line caps at 70% CLTV with a 700 minimum credit score and a $500,000 maximum line. Market surveys report higher caps elsewhere, such as the 80% figure Experian cites for the broader market. Primary-residence lines can reach 90% CLTV, but only at 720 or better.
Does the HELOC payment count in the DSCR?
On a DSCR purchase loan, the ratio generally compares rent against that loan’s own payment, so the line’s payment may sit outside the ratio. It still has to be paid. Conventional-style reviews may count it in your DTI. Ask the purchase lender which test applies before you draw.
Can I hold the line in an LLC?
No. These lines require title in your individual name or a revocable living trust. An LLC-titled rental needs a vesting change or a DSCR cash-out refinance instead. A DSCR purchase loan can be made to an LLC, depending on program guidelines.
Do I need an appraisal?
Often no. Because an investment line caps at $500,000, it normally uses automated valuation and commonly closes without a traditional appraisal. You can request a full appraisal, and a higher CLTV may call for a secondary valuation. Only primary-residence lines can exceed $500,000, and those always require a full appraisal.
