The Quick Read: The right line for your situation is the one that matches your collateral, your combined leverage, and how your property is titled. A line only creates cash, and a separate purchase loan still has to close. On Lendmire’s wholesale network, an investment-property line stops at 70% combined loan-to-value (CLTV).
- A line changes where the down payment comes from. It does not remove the down payment, and it adds a second monthly payment.
- On an investment property, the network’s lines run up to $500,000 and need a credit profile of 700 or better.
- LLCs cannot hold title on these lines, which is the sharpest difference from a DSCR loan.
- Two approvals must both hold: the line, and then the purchase lender’s acceptance of borrowed funds.
- Clearing the DSCR test on the new property does not mean the deal cash flows once the line payment is counted.
Lendmire is a mortgage broker. It places these files with select wholesale lenders and is not the lender, so every figure below is subject to lender guidelines and full file review. It is not 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.
Key Terms Defined
HELOC (home equity line of credit): a revolving line secured by a property you own, which you draw from as needed up to a limit.
CLTV (combined loan-to-value): your first mortgage plus the new line, divided by the property’s value. Investopedia defines it the same way.
DSCR (debt service coverage ratio): monthly rent divided by the property’s monthly principal, interest, taxes, insurance, and any HOA dues. Lenders use it to judge whether a rental pays for itself.
Draw period: the stretch when you can borrow from the line and payments are often interest-only.
Repayment period: the stretch after the draw period ends, when the balance amortizes and the payment steps up.
Seasoning: how long funds or a property have been in place before a lender treats them as established.
What Does a HELOC Actually Do for a Portfolio Down Payment?
A HELOC does not buy the rental. It turns equity you already hold into cash, and you then use that cash as the down payment on a separate purchase loan. You end up with two loans on two properties.
That structure is why the best program for your situation depends on more than the line itself. Picture a line on your primary home, plus a DSCR purchase loan at 75% loan-to-value (LTV) on the new rental. Between them, you have borrowed close to the full price of the rental. A line secured by a rental you already own is different, because an investment line caps at 70% CLTV. A line makes sense when the new property can carry its own mortgage and the line payment too.
Two different products get called an investment property HELOC. One is a line secured by a rental you already own. The other is a standard line on your primary home, drawn and then spent on the down payment. Lenders treat them differently, and so does the risk.
Which Property Should Secure the Line?
Your primary home usually gets the more flexible terms, but you put your home at risk. A rental-secured line keeps the risk on the investment, but it is capped lower and fewer lenders offer it. A property held in an LLC generally cannot hold a line at all.
Here is how the three setups compare on this network.
| Collateral | Leverage ceiling | Main risk or catch |
|---|---|---|
| Rental you own personally | 70% CLTV, up to $500,000 | Needs 700+ credit |
| Primary residence | Up to 90% CLTV, only at 720+ | Your home secures the debt |
| Rental held in an LLC | Not eligible | Needs a vesting change first |
Nasdaq’s SmartAsset piece on HELOC down payments flags the foreclosure exposure that comes with funding a purchase from a primary-residence line. That risk is real, and it belongs in the decision before the numbers do.
On the investment side, both the 720 and 700 credit tiers reach the same 70% CLTV. A higher score buys eligibility, not extra leverage, and 700 is a hard floor with no tier beneath it. Only primary residences can carry lines above $500,000, so those larger lines are off the table for rental collateral.
The market reports other figures for investment lines, and lenders outside this network may go higher. Those describe the broader market. The network ceiling for investment collateral is 70% CLTV.
How Big a Line Does Your Equity Support?
Take the rental’s value, multiply by the allowed CLTV, and subtract what you already owe. What remains is your borrowing room, and the line size cannot exceed $500,000 on investment collateral. The minimum line is $25,000 (Michigan’s floor is $10,000).
Run the numbers on a rental valued at 100 units of value. At 70% CLTV, total debt can reach 70 units. If the first mortgage already sits at 50% of value, the line has room for about 20% of value. Equity above the first mortgage is the whole story here.
Two program details change how you size the line:
- At least 75% of the line is drawn at closing. You cannot open a large line and leave it idle. Size it to the down payment and closing costs, not to the maximum the equity allows.
- Pricing floats and never converts to fixed. The payment can move through both the draw and the repayment period.
Investment lines run one structure: a 5-year interest-only draw followed by a 25-year fully amortizing repayment. Lines at or below $500,000 ordinarily use an automated valuation, so an investment line commonly closes with no traditional appraisal. A borrower may still request a full appraisal.
How Do Lenders Underwrite the Line?
A line is underwritten on you, not on the rental’s rent. Lenders look at credit, income, debt-to-income (DTI), the property, and how it is titled. The rental income matters only as part of your overall picture.
Here is what the lender checks, step by step:
1. Credit. An investment line needs at least a 700 profile. The score model keys to the primary wage earner, and the report can be no more than 90 days old at closing.
2. DTI. The maximum is 50%, measured on the interest-only payment as if you had drawn the full line. A big line therefore shows up at its largest in your ratio.
3. Property. Single-family, 2-4 units, PUD, townhome, and condo (including non-warrantable) are eligible. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not.
4. Title. The borrower must be an individual or an inter vivos revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title.
5. Credit history. A bankruptcy needs 4 years of seasoning from discharge or dismissal. Investment files follow the 7-and-4-year seasoning path: 7 years for a foreclosure and 4 years for a deed-in-lieu, pre-foreclosure, or short sale.
The CFPB describes the general product the same way: a line you can spend up to its limit during a draw period, with variable rates and payments that follow the balance. Its example of a draw period “that could last 10 years” is an illustration, not a program term. The network’s investment lines use the 5-year draw above.
These lines are available in Lendmire’s 16 full-service states, which is narrower than its 41-market DSCR footprint. Check that your property’s state is one of them before you plan a purchase around a line.
From Line to Closing: The Sequence That Works
Open and fund the line before you shop seriously. The line and the purchase loan are two separate files, and the purchase lender will want to see the money sourced and seasoned.
1. Decide the collateral. Pick between your primary home and a personally titled rental.
2. Check your title. If the rental sits in an LLC, plan a vesting change or a different tool.
3. Qualify and close the line. Expect the line lender to run credit, DTI, and valuation.
4. Draw and document. Keep the HELOC statement, the draw record, and bank statements showing the money moving into your account.
5. Confirm the purchase lender’s borrowed-funds rule. Lenders may treat borrowed money differently for the down payment, closing costs, and reserves. Reserves often need to come from unborrowed funds, so ask before you draw.
6. Close the purchase loan. For a rental, that is usually a DSCR loan.
7. Plan the exit. Pay the line down from cash flow, refinance the new property, or repay it with a cash-out refinance after the property is stabilized.
The CFPB’s HELOC booklet notes that when the draw period ends, you enter a repayment period and the payment can change. Plan for that step-up on day one, not in year six.
Can Your Cash Flow Carry Both Payments?
A DSCR purchase loan typically reads the new property’s rent against its own payment, and the line payment stays outside that ratio. That helps you qualify. It does not change what leaves your bank account each month.
DSCR loans are designed for non-owner-occupied investment properties. Because they are business-purpose investor loans, they are reviewed differently from a standard owner-occupied mortgage.
On Lendmire’s network, DSCR purchase files typically land at 75%-80% LTV. A select tier reaches 85% LTV with a score around 700 or better. Many programs start at a 1.00 coverage floor, while a separate select-lender path takes coverage below 1.00 with leverage and terms adjusted. Stronger ratios open better pricing and leverage.
DSCR compares rent to principal, interest, taxes, insurance, and HOA dues only. Clearing 1.00 is not the same as positive cash flow. Repairs, vacancy, management, utilities, and capital expenses all sit outside the calculation, and so does your line payment.
Here is how three scenarios look in practice.
| Scenario | DSCR read | Real pocketbook picture |
|---|---|---|
| Strong rent, small line | Clears around 1.2x | Cushion remains after line |
| Rent just covers payment | Right near 1.00x | Line payment turns it negative |
| Rent below payment | Below 1.00x | Select lenders only, adjusted terms |
The middle row is the one to watch. The file qualifies, and the investor still funds the line payment from other income. Stress-test the line separately, and assume the draw payment moves.
Where the General Rule Breaks
A HELOC can fund a down payment, but only when the file fits the line’s rules. These edge cases are where it fails.
No seasoned rental, no rental-secured line. A first-time investor has nothing to borrow against. The fallbacks are a primary-home line, savings, a partner, or a smaller first deal.
An LLC-titled portfolio. If your rentals are already deeded to an LLC, the line cannot attach to them. You would need a vesting change or a DSCR cash-out refinance instead. DSCR loans to LLC-titled borrowers are available, subject to lender program eligibility, which is the opposite of the line rule.
Portfolio limits. A borrower is limited to three lines. Combined exposure caps at $2,000,000 on one wholesale program (the higher-leverage program) and $750,000 on another (the longer-runway program). A borrower who owns more than 15 financed properties is not eligible.
Ineligible property types. Manufactured homes, log homes, and barndominiums are not offered in the network’s DSCR programs, and manufactured homes are also off the line side.
Line freezes. Lenders can generally freeze or reduce a line if values fall or finances weaken. Do not count on drawing again later to cover a surprise.
Credit stacking. Applying to several lenders over a few months can pull your score down. Choose collateral and program first, then apply once.
HELOC, DSCR Cash-Out, or Home Equity Loan?
Pick the tool by what you hold and what you need. A line is flexible but floats. A cash-out refinance is a single loan against one property. A home equity loan is a fixed lump sum.
| Factor | Investment HELOC | DSCR cash-out | Home equity loan |
|---|---|---|---|
| Max leverage | 70% CLTV | About 75% LTV | Varies by lender |
| Title | Individual or revocable trust | LLC allowed* | Usually individual |
| Reviewed on | Your credit and DTI | Property rent coverage | Your credit and DTI |
| Seasoning | Lender-specific | About 6 months | Lender-specific |
*Subject to lender program eligibility.
A DSCR cash-out refinance qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. That makes it the more natural tool for an LLC-held rental, a self-employed investor with a high DTI, or a larger portfolio. Lendmire’s complete DSCR loans guide covers how those files are built.
If your equity sits in a rental and the line is meant to fund the next purchase, Lendmire’s piece Best Investment Property HELOC Program Behind a DSCR Loan for a Down Payment walks through the sequencing in more detail.
When Is This the Wrong Tool?
A line is wrong when you have no repayment path. A revolving, floating-price line is a poor fit for a permanent down payment that you plan to carry for years without paying it down.
It is also wrong when reserves are thin. Purchase lenders commonly want around 6 months of PITIA in reserves, though conservative files at modest leverage can see reserves waived and larger loans step up. If the line is your only cushion, the purchase file may not hold together.
And it is wrong when the new rental barely clears coverage. A property near 1.00x with a second payment on top leaves no room for vacancy or repairs.
What Should You Ask Before You Apply?
Ask the line lender:
- Is the collateral eligible, and does the title qualify?
- What is the CLTV ceiling for my occupancy and credit profile?
- How much must I draw at closing?
- What is the draw and repayment structure?
Ask the purchase lender:
- Are borrowed funds accepted for the down payment, closing costs, and reserves?
- What documentation do you need on the draw?
- Does the line payment enter any ratio on this program?
A broker that shops multiple wholesale lenders can match your file to a program in a way no single lender’s page can. Lendmire’s piece on the single-property version, Best Investment Property HELOC Program for a Rental Down Payment, goes deeper.
Frequently Asked Questions
Can a HELOC cover the whole purchase price, or only the down payment?
Typically only part of it. A line creates cash for the down payment and closing costs, while a separate purchase loan covers the rest. On an investment-property line, the ceiling is 70% CLTV and the line caps at $500,000, so it rarely stretches to a full purchase.
Does the HELOC payment count against my DSCR?
On most DSCR purchase files, the ratio uses the new property’s rent against its own payment. The line payment is still real cash leaving your account, so treat it separately. Check each program, because lenders differ.
Can an LLC take out an investment property HELOC?
No. On this network, title must be held by an individual borrower or a revocable living trust. An LLC-owned rental needs a vesting change or a DSCR cash-out instead.
Can I draw from the line later instead of all at once?
You must draw at least 75% of the line at closing. After closing, the minimum subsequent draw is $1,000 (Texas is $4,000) on the program that states it. Plan the amount carefully up front.
Is a HELOC better than a DSCR cash-out refinance?
It depends on your title, equity, and cash-flow plan. A line fits a personally titled property and a small, short-term need. A DSCR cash-out fits an LLC-held or larger portfolio.
If you are considering a home equity line and want to see how the numbers work, Lendmire can help you compare HELOC options based on the property, the equity available, credit profile, combined leverage, and your goals. Reach the team at 828-256-2183.
Investors who reach the ceiling on their lines may consider a DSCR cash-out refinance as the portfolio grows.
