The Quick Read: A home equity line that funds an investment house is its own approval, separate from the purchase loan, qualified on your equity, credit, and debt-to-income; on an investment property in Lendmire’s wholesale network it typically needs a 700 score, stays at or below 70% combined loan-to-value (CLTV), and caps at $500,000.
- The line qualifies you and your equity. The purchase loan, if it is a DSCR loan, qualifies primarily on the new property’s rental income covering its payment, subject to lender guidelines.
- A line on your primary home reaches higher leverage than a line on a rental. On this network the top ceiling is 90% CLTV, and only at a 720 or better credit profile.
- The line’s payment is real money. A coverage ratio above 1.00 on the new house does not make the whole picture cash-flow positive.
- Title matters. An LLC cannot hold title on these lines, so a rental deeded to an LLC needs a vesting change or a different tool.
Two Loans, Two Files
A HELOC never replaces the purchase loan. You end up with two separate loans and two separate underwriting files. One lender looks at your equity, credit, and debt load to size the line. A second lender looks at the house you are buying.
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.
That split is the core idea of this article. When the purchase loan is a DSCR loan, the property’s rent has to cover its own payment. When the equity line is the source of your down payment, you have to cover that payment too. Lendmire’s complete DSCR loans guide covers the purchase side in full.
Lendmire is a mortgage broker, not the lender. It places these files with select wholesale partners, and every figure below is subject to lender guidelines and full file review. Equity-line availability is also narrower than the DSCR footprint, because Lendmire offers these lines only in its 16 full-service states.
Key Terms Defined
HELOC: A home equity line of credit is a revolving line secured by a property. You borrow against it during a draw period and repay it afterward.
CLTV: Combined loan-to-value is your first mortgage plus the new line, divided by the property’s value.
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 payment, which includes principal, interest, taxes, insurance, and any HOA dues.
PITIA: Principal, interest, taxes, insurance, and association dues. It is the full monthly payment on a property.
Occupancy: How the property is used. A primary residence is where you live, and an investment property is held to rent out.
What Is the Line Secured By?
You have two choices for collateral. You can open the line on the home you live in, or on a rental you already own. The choice changes the leverage, the credit requirement, and how much risk you carry.
| Factor | Line on primary home | Line on an existing rental |
|---|---|---|
| Max CLTV | Up to 90%, only at 720+ | 70% |
| Min credit | 600 program floor | 700 |
| Max line | Up to $750,000 | $500,000 |
| Draw structure | 3-year or 5-year draw | 5-year draw only |
| What is at risk | Your home | The rental |
The rental route is the harder one. NerdWallet notes that lenders see higher default risk on investment properties. It reports that market-wide, investment-line borrowers typically need about a 720 score, and that maximum LTV tops out near 80%. On Lendmire’s network, an investment property line is capped at 70% CLTV with a 700 minimum.
Credit above 700 buys eligibility rather than leverage on an investment line. A 720 and a 700 both reach 70%, and there is no tier below 700.
The Requirements, Line by Line
Investment lines are stricter than primary-home lines. Experian makes the same point: they generally need a higher score, lower DTI, and stronger reserves. Here is what that looks like across Lendmire’s network.
Equity and CLTV. On an investment property, the ceiling is 70% CLTV. Add your first mortgage balance to the line, and the total cannot exceed 70% of the property’s value. On a primary residence, 90% exists only at a 720 or better profile.
Credit. An investment line has a 700 minimum, and the program floor on primary homes is 600. The lender uses a single-bureau score tied to the primary wage earner. The report can be no more than 90 days old at closing, and rescores are not available.
DTI. The maximum is 50%. The lender calculates the payment on the interest-only amount for the maximum draw, not just what you borrow on day one. That is a tougher test than it sounds.
Line size. Lines run from $25,000 to $750,000, but an investment line stops at $500,000. A line above $500,000 is for primary residences only. It requires 700 or better (720 on the 5/25 structure described below), caps at 75% CLTV, and needs a full appraisal.
Valuation. Because an investment line cannot exceed $500,000, it commonly closes on an automated valuation with no traditional appraisal. A higher CLTV may require a secondary valuation, and you can always request a full appraisal.
Reserves and documents. Expect leases and Schedule E to document rental income. Self-employed borrowers can qualify on documented income under the applicable program, subject to lender guidelines.
Derogatory history. 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.
Limits on you. A borrower can hold at most three lines. A borrower with more than 15 financed properties is not eligible.
What Properties and Titles Qualify?
Eligible collateral includes single-family homes, 2-4 unit properties, PUDs, townhomes, and condominiums, including non-warrantable condos. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agriculturally zoned properties are not eligible.
Title is the sharpest difference from a DSCR loan. The borrower must hold title as an individual or in a revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title.
Many investors keep rentals in an LLC. If yours is deeded that way, you need a vesting change before the line, or a DSCR cash-out refinance instead. Lendmire’s DSCR purchase programs can lend to an LLC borrower, subject to program terms, but the equity line cannot.
How the Purchase Sequence Works
The order of steps matters more than most investors expect. Here is the sequence from first call to paydown.
1. Choose the collateral. Decide whether the line sits on your primary home or an existing rental, using the table above.
2. Qualify the line. The lender checks value, your first mortgage balance, credit, DTI, and reserves. NerdWallet adds that rentals may draw extra appraisal scrutiny and a request for proof of long-term tenants.
3. Open the line before you go under contract. The funds need to exist, and the line needs to be in place, before the purchase lender reviews your file. Opening it first also tells you what you can actually spend.
4. Draw the funds and keep a paper trail. Lenders on the purchase side commonly want to see where your cash came from. Treatment of borrowed funds varies by lender, so ask before you commit to a contract.
5. Qualify the purchase loan. On a DSCR purchase, most files land at 75%-80% LTV, which means 20%-25% down. Select programs reach 85% LTV with roughly a 700+ score. Whether the line’s payment counts against you depends on the program.
6. Plan the exit. Many investors repay the line with a DSCR cash-out refinance after the new house seasons, with about six months a common expectation. Cash-out tops out around 75% LTV on standard rentals and 70% on short-term rental collateral.
The line works as a bridge, not a permanent loan. Coverage is a floor for specific programs, not a promise. A 1.00 ratio is where many select programs start, and a separate select-lender path takes coverage below 1.00, with leverage and terms adjusted.
Worked Example in Percentages and Ratios
Run the numbers on a borrower with a 720+ score and a primary home. Say the home is worth 100 units, and the first mortgage is 50 units, which is 50% of value. A 90% CLTV ceiling leaves headroom of 40% of value. A prudent borrower does not use all of it.
Now size the draw to the need. The investor targets a rental purchase at 80% LTV, so the line has to cover the 20% down payment plus closing costs. The line is sized for that amount and nothing more. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
Here is how the pieces line up:
| Step | Input | Result |
|---|---|---|
| Line on primary home | 50% first mortgage, 720+ score | Headroom up to 90% CLTV |
| Purchase loan | 80% LTV, 20% down | Line funds the down payment |
| Total leverage | Two loans on two properties | Near 100% of the new house’s price |
| New house coverage | DSCR around 1.20x | Rent exceeds PITIA by roughly one-fifth |
| Line carrying cost | At least 75% drawn at closing | Interest-only payment starts immediately |
That last row is where deals get tight. A 1.20x coverage ratio means the rent runs about one-fifth above PITIA. If the cushion is thinner than the line’s payment, you are funding the gap from your own income.
DSCR compares rent to PITIA only. Clearing 1.00 is not the same as positive cash flow, because repairs, vacancy, management, utilities, and capex sit outside the calculation. Add the line’s payment and the picture gets thinner still.
Where the General Rule Breaks
The bank may not allow it. Some large retail lenders prohibit using HELOC funds toward an investment purchase. One investor reports a bank refusing to allow it as a down payment, and the practical lesson is to read the line agreement and disclose the use honestly.
The line can shrink. According to the federal HELOC guidance, a HELOC is an open-end line you can draw on repeatedly. It warns that if you cannot repay on schedule, you could lose the home securing it. Some plans can also reduce your credit line if the property’s value falls, so the line you counted on may not be there in a down market.
A sale triggers payoff. Under the federal HELOC brochure, if you sell the home, you generally have to pay the line off in full right away. A line on a rental you plan to sell therefore needs an exit before you list.
Pricing floats. The line’s pricing floats through both the draw and repayment periods and never converts to fixed. Your payment can move while the rent on a long lease does not.
The draw is mostly spent on day one. At least 75% of the line is drawn at closing. You cannot open a large line “just in case” without paying on most of it.
Draw and repayment structures differ. Primary homes and second homes have two structures. The 3/17 structure has a 3-year interest-only draw and a 17-year fully amortizing repayment. The 5/25 structure has a 5-year draw and a 25-year repayment. Investment lines run only the 5/25 structure. After closing, later draws carry a $1,000 minimum on that structure.
High DTI changes the route. Some investors use a line precisely because their DTI is too high for a conventional investor loan, since a DSCR purchase is reviewed primarily on property-level rental income. The line, however, still has to clear the 50% DTI ceiling by itself.
Not every house works. DSCR on manufactured homes (single- and double-wide), log homes, and barndominiums is not offered in the network. The equity-line program also excludes manufactured homes, co-ops, and condotels.
Tax treatment can depend on how the funds are used and how the property is held; borrowers should keep clear records and speak with a qualified tax professional before relying on any deduction.
Is a HELOC the Right Tool?
A line suits short holds. Think of a flip, or a purchase you will refinance out of once it seasons. It fits poorly when the cash stays tied up in the property for years, because the line’s payment keeps running the entire time.
Here are the alternatives side by side.
| Option | Qualifies mainly on | Typical fit |
|---|---|---|
| HELOC on primary home | Your equity, credit, DTI | Short-term down payment bridge |
| HELOC on a rental | Your equity, credit, DTI | Smaller draws against an owned rental |
| DSCR cash-out refinance | Property rent coverage | Pulling equity into long-term financing |
| DSCR purchase, more cash down | Property rent coverage | Buying without a second loan |
A larger down payment can lower the monthly payment and lift the coverage ratio. It never erases leverage caps, credit floors, reserve rules, or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage.
If you are weighing the line against a DSCR cash-out, Lendmire’s piece on whether an investment property HELOC makes sense to buy an investment house covers that comparison.
Before you commit, run a stress test. Take the new house’s rent, then subtract vacancy and repairs. Then subtract the line’s payment on the full drawn balance. If the deal only works with zero vacancy, the draw is too big.
Frequently Asked Questions
Can you use a HELOC to buy an investment property?
Yes, if the line’s agreement allows it and the purchase lender accepts the funds as your down payment. Some lenders restrict investment use, and purchase lenders differ on how they treat borrowed funds. Ask both sides before you go under contract.
Does the line replace the purchase mortgage?
No. It is a separate loan with its own approval, and it usually funds the down payment, not the whole price. You still need a purchase loan for the rest.
What credit score does an investment-property line need?
On Lendmire’s network, an investment property line typically needs 700 or better, with a 70% CLTV ceiling. A primary-residence line starts at a 600 program floor, and its 90% ceiling requires 720 or better. Subject to lender guidelines.
Can an LLC hold title?
No. These lines require title held by an individual or a revocable living trust. A rental already deeded to an LLC needs a vesting change first, or a DSCR cash-out refinance instead.
Does a HELOC payment count against a DSCR purchase?
It depends on the program. A DSCR purchase is reviewed primarily on the new property’s rent covering its payment, subject to lender guidelines. Even where it does not count, the payment still comes out of your real cash flow.
