The Quick Read: To buy a rental in cash with a home equity line, you typically need at least a 700 credit score, a combined loan-to-value of 70% or less on an investment-property line, title held in your own name or a revocable trust, and a debt-to-income ratio of 50% or below, with most of the line drawn at closing.
- An investment-property line tops out at 70% combined loan-to-value and a $500,000 maximum line, subject to lender guidelines.
- A line on your primary home can reach 90% combined loan-to-value, but only with a credit profile of 720 or better.
- Investment lines use a 5-year interest-only draw followed by a 25-year repayment, and the pricing floats the whole time.
- An LLC cannot hold title on the line, which is the sharpest difference from a DSCR loan.
- The line is a bridge, so the plan to repay it matters as much as the approval.
Which Property Secures the Line?
Two different products hide under one search phrase. The first is a line secured by your primary home, which you then spend on a rental purchase. The second is a line secured by a rental you already own, which you draw on to buy the next one.
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.
Lenders treat them differently. NerdWallet notes that lines on investment property are not offered by all lenders and carry strict qualification requirements. That shrinks the lender pool and explains why many cash-purchase investors borrow against their own home instead.
The reason is lender logic. Borrowers tend to protect the home they live in before anything else, so a line on a primary home looks safer to a lender than a line on a rental. That safety shows up in the leverage limits, which the next sections lay out.
What the Requirements Look Like Side by Side
Across the wholesale network Lendmire places home equity lines with, the investment-property line is the tightest version of the product. Credit has a hard floor, leverage has a hard ceiling, and the line size is capped. Every figure below is a typical guideline, not a promise, and each file is reviewed individually.
| Factor | Investment property line | Primary-home line |
|---|---|---|
| Max combined LTV | 70% | Up to 90% (720+ credit only) |
| Minimum credit | 700 | 600 program floor |
| Maximum line | $500,000 | $750,000 |
| Draw structure | 5-year draw, 25-year repayment | Two draw structures |
| Valuation | Automated, commonly no appraisal | Full appraisal above $500,000 |
| Max DTI | 50% | 50% |
Credit above 700 on an investment line buys eligibility, not extra leverage. A 700 score and a 720 score both reach the same 70% ceiling, and there is no tier below 700.
A line above $500,000 is available only on a primary residence. It caps at 75% combined loan-to-value and requires a full appraisal.
Combined loan-to-value (CLTV) adds your existing mortgage balance and the new line together, then divides by the property’s value. At 70% CLTV, a rental with an existing mortgage equal to 45% of its value leaves room for a line worth up to 25% of its value. A rental with no mortgage leaves room for up to 70%.
How Market Surveys Compare
Lenders publish different numbers, and you will see them in search results. NerdWallet reports a typical maximum of 80% loan-to-value on investment-property lines, with many lenders staying below 70%. The White Coat Investor reports that a credit score of at least 720 is common.
Those are market-wide statistics, not this network’s terms. On an investment property, the network ceiling is 70% CLTV with a 700 minimum score. The 90% figure applies only to primary-residence and second-home lines, and only with a 720 or better profile.
How Underwriting Treats a Cash Purchase Funded by the Line
Underwriting a line used for a cash purchase follows a predictable sequence. Here it is step by step.
1. Pick the collateral. A line on your primary home is judged on home equity, credit, income and total debts. A line on a rental is judged on rental equity and your overall strength as a borrower.
2. Size the line. The lender takes the property value, multiplies by the maximum CLTV, and subtracts what you owe. On an investment property the multiplier is 70%.
3. Check credit and debt. The lender pulls a single credit score keyed to the primary wage earner. Your debt-to-income ratio is then reviewed around the interest-only payment calculated at the maximum draw, not on the balance you plan to use.
4. Value the property. Lines at or below $500,000 usually run an automated valuation with no traditional appraisal. A higher CLTV may trigger a secondary valuation, and you can always ask for a full appraisal.
5. Close and draw. At least 75% of the line is drawn at closing on these programs. This is not a standby line you open now and tap later.
6. Fund the purchase. Your title company wires the draw as your cash for the rental purchase.
7. Plan the exit. You repay the line from rents or other savings, or you refinance the rental into long-term financing and pay the line off.
Step three matters most for investors who plan to borrow again. A line payment counts in your debt-to-income ratio for any later loan that is underwritten on personal income. One BiggerPockets investor describes qualifying for a new mortgage with the line’s minimum payment included in DTI.
Step five also deserves a second look. Size the line to the purchase, not to the maximum you could get.
Structures and Variations Inside the Product
The line is a standalone product that can sit in first or second lien position. A line in first position on a free-and-clear rental is common for investors who own property outright.
On investment properties, the draw period runs five years, interest-only. Then a 25-year repayment period begins in which the balance fully amortizes. Pricing floats across both periods and never converts to fixed.
After closing, additional draws typically carry a $1,000 minimum on programs that state one. The CFPB defines a home equity line as open-end credit you can borrow against repeatedly during a draw period. After that period ends, you stop borrowing and enter repayment.
Property type matters too. 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 agricultural-zoned properties are not offered.
There are also exposure limits. A borrower is limited to three lines, with combined exposure capped at $2,000,000 on the higher-leverage program. A borrower with more than 15 financed properties is not eligible.
Availability is narrower than the DSCR side of the business. Home equity lines run only in Lendmire’s 16 full-service states, while DSCR programs cover 41 markets, including Washington, D.C.
Where the General Rule Breaks
Your rental sits in an LLC. Title on the line 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 property already deeded to an LLC needs a vesting change, or you move to a DSCR cash-out refinance instead, subject to lender program eligibility.
You are self-employed. Documented income under the applicable program can support the file, subject to lender guidelines. Business bank accounts need a 680 minimum for the deposit analysis. Investment already floors at 700, so bank-statement income is never the limiting factor on an investment line.
Your property value drops. A line is not a guaranteed commitment to fund later. The CFPB’s HELOC booklet notes that a lender can reduce your credit line if the value of your home falls. That matters if you opened the line in order to close a purchase later.
You sell the collateral. The same booklet says that if you sell your home, you are generally required to pay off the line in full right away. Investors who plan to sell the secured property need to plan for that.
You buy in a state the program does not cover. The line is limited to 16 states. A deal outside them needs a different tool, such as a DSCR purchase loan.
You plan to deduct the interest. 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.
The Exit: Where DSCR Loans Come In
A line is short-term, flexible funding. A DSCR loan is the long-term option that investors commonly use to replace it. Lendmire’s complete DSCR loans guide covers how those loans work in full.
A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. The lender divides monthly rent by PITIA, which is principal, interest, taxes, insurance and any association dues. Many select programs start at 1.00 coverage, and a separate select-lender path takes coverage below 1.00 with leverage and terms adjusted. Stronger ratios open better pricing and leverage.
Run the exit test before you draw. On a standard rental, a DSCR cash-out refinance tops out around 75% LTV across most of the network, with about 6 months of seasoning as the common expectation. On short-term-rental collateral, the cash-out ceiling is 70%. That seasoning gap is the time your line balance stays outstanding. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
Clearing 1.00 does not mean the property produces positive cash flow. DSCR compares rent to PITIA only. Repairs, vacancy, management, utilities, and capital expenses sit outside the calculation.
The treatment of recently borrowed funds, and how a line balance counts against you, varies by program. Ask the broker how the specific DSCR lender will view a line-funded purchase before you draw, not after.
What Does the Decision Look Like in Practice?
Picture two investors who each want to buy a rental outright. One owns a primary home with a lot of equity and a 740 credit score. The other owns a free-and-clear duplex and a 710 score. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.
The first can look at a primary-home line, where the ceiling reaches 90% CLTV at 720 or better, but the investor puts the home at risk. The second looks at an investment-property line capped at 70% CLTV, which keeps leverage lower and the personal residence out of it.
Neither has an easy answer. The primary-home line gives more room, but a downturn could leave the investor owing more than the value of both properties. Investors on BiggerPockets point out that using a primary-home line for the down payment leaves no cushion, which makes cash flow thinner.
The sound filter is two tests. First, you need enough equity and credit to qualify for the line. Second, the rental needs enough coverage to carry the balance, or to refinance out of it, without relying on your personal income.
Some investors skip the line and put down 20% to 25% on a DSCR purchase loan. Most files land at 75% to 80% LTV on a purchase, and select programs reach 85% LTV with roughly a 700 or better score. A purchase loan costs more cash up front but avoids a variable balance secured by your home.

Frequently Asked Questions
Can an investment-property line pay the full price of a rental?
Yes, if the line is large enough, since you draw the cash and the title company wires it as your funds. The practical limit is the 70% CLTV ceiling on an investment property and the $500,000 maximum line. A larger purchase usually needs a second source of cash or a primary-home line.
Does the credit score need to be 700 or higher?
For an investment-property line, yes, and 700 is a hard floor with no tier beneath it. Primary-home lines have lower floors, but the 90% CLTV ceiling requires 720 or better. Programs differ by lender, so confirm which tier your score reaches.
Can I hold the property in an LLC?
Not on the line itself. Title must sit with you individually or in a revocable living trust. If the property is already in an LLC, you would need a vesting change or a DSCR cash-out refinance instead.
Will I need an appraisal?
Usually not on an investment line, because lines at or below $500,000 commonly run an automated valuation. A higher CLTV may require a secondary valuation, and you can request a full appraisal in any case. Lines above $500,000 are available only on primary residences and need a full appraisal.
Is a line cheaper or safer than a DSCR purchase loan?
Neither is automatically better. A line is flexible but carries a variable payment, and most of it is drawn at closing. A DSCR purchase loan needs a down payment, but it is reviewed on property-level rental income and has a defined structure, subject to lender guidelines.
Next Step
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.
