The Quick Read: A home equity line of credit (HELOC) on a rental you already own can fund the next purchase. It is a personal credit decision secured by that rental, so the line must clear its own tests: a 700 minimum credit profile, a 70% combined loan-to-value ceiling on investment lines, and a $500,000 maximum line, all subject to lender guidelines. Combined loan-to-value (CLTV) adds your first mortgage and the new line together, then divides by the property’s value.
- Across our wholesale network, an investment-property line tops out at 70% CLTV. That holds at 700 and at 720, so a higher score does not buy more leverage.
- Lines on investment properties run from $25,000 to a $500,000 maximum, and most close on an automated valuation instead of a full appraisal.
- The line must be held by you personally or by a revocable living trust. An LLC cannot hold title on these lines.
- The HELOC and the next purchase loan are two separate approvals made by two different lenders.
- At least 75% of the line is drawn at closing, so you start paying on most of it right away.
What Is an Investment Property HELOC?
Equity is the property’s value minus what you owe on it. The line lets you borrow against that equity, repay, and borrow again within the draw period.
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.
The structure on investment lines is a 5-year interest-only draw period followed by a 25-year fully amortizing repayment period. Pricing floats through both periods and never converts to a fixed figure. That matters because your payment moves with the balance and the market, which is a very different animal from a fixed-term loan.
NerdWallet points out that not every lender offers a line on an investment property, and those that do apply strict requirements. That matches what we see.
One more availability note. Lendmire brokers these lines only in its 16 full-service states, which is narrower than its DSCR footprint of 41 markets, including Washington, D.C.
Requirements at a Glance
The core requirements are a 700 credit minimum, a 70% CLTV ceiling, a 50% debt-to-income cap, and an eligible property held in your own name. Each figure applies to investment properties specifically. Primary residences and second homes follow looser tables, and those figures should never be read across.
| Factor | Investment-property line | Why the lender asks |
|---|---|---|
| Credit | 700 minimum, no tier below | The line rests on your personal credit, not the rental’s income |
| Max CLTV | 70% at 720+ and at 700+ | Keeps an equity cushion |
| Line size | $25,000 to $500,000 | Caps exposure per property |
| DTI | 50% maximum | Tests your total debt load |
| Valuation | Automated valuation is typical | Lines this size rarely need an appraisal |
| Title | Individual or revocable trust | LLCs cannot hold title |
Treat these as typical ranges from select lenders in the network. Every file is reviewed individually, and none of this is a commitment to lend.
For context, NerdWallet reports that lenders commonly want at least 20% equity remaining on an investment property. On our network an investment line stops at 70% CLTV, so you keep at least 30% equity in the property.
On a primary residence the ceiling reaches 90% CLTV, but only at a 720-or-better credit profile. Don’t let that number leak into your rental math. It does not apply to a rental.
How Underwriting Treats the Line, Step by Step
Underwriting a rental HELOC runs through five checks: equity, your credit and debt, the property type, title, and the valuation. You are the borrower, so your file matters more than the rental’s income.
1. Equity test. The lender takes the property’s value, adds the new line to the first mortgage, and checks the total against the 70% CLTV ceiling. Whatever room is left is your potential line.
2. Credit and debt. The 700 floor applies, because the line is underwritten on your personal credit rather than the rental’s income. Debt-to-income can reach 50%, and the lender reviews your file on the interest-only payment calculated on the maximum draw, not on what you plan to borrow. That is stricter than it sounds.
3. Property eligibility. Single-family homes, 2-4 unit properties, PUDs, townhomes, and condominiums (including non-warrantable ones) are eligible. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agriculturally zoned properties are not offered.
4. Title and vesting. Title sits with you or your revocable living trust. A rental already deeded to an LLC needs a vesting change first, or a DSCR cash-out refinance instead.
5. Valuation. Because investment lines cap at $500,000, they usually run on an automated valuation with no traditional appraisal. A higher CLTV may trigger a secondary valuation, and you can ask for a full appraisal anyway.
Credit history details also matter. A bankruptcy needs 4 years of seasoning from discharge or dismissal. Investment files with foreclosure history follow a 7-year path for a foreclosure and a 4-year path for a deed-in-lieu, pre-foreclosure, or short sale.
Exposure caps apply as well. You can hold three lines at most. And an owner of more than 15 financed properties is not eligible.
A Worked Example in Percentages
Say you own a rental, and your first mortgage balance equals 45% of its value. At a 70% CLTV ceiling, the line can take up the remaining 25% of value. That is the ceiling, not a promise.
Now apply the line-size cap. If 25% of the rental’s value comes to more than $500,000, the $500,000 maximum binds first. On most single-family rentals, the CLTV ceiling binds long before the dollar cap does.
Next, the draw requirement. At least 75% of the line is drawn at closing. So a line sized at 25% of value means you immediately carry a balance near 19% of value. You cannot hold it as a dormant reserve for a future offer.

Using One Rental’s Equity to Buy the Next
The sequence is: line first, purchase second, permanent loan third. Done in that order, the line works as bridge capital for a down payment while a long-term loan carries the rest.
1. Open the line on the rental. This is the personal approval described above. The funds arrive mostly drawn.
2. Use the funds for the down payment. Some investors also cover closing costs or renovation from the line. A few pay cash for the whole property.
3. Place permanent financing on the new property. For most buyers, that is a DSCR purchase loan, which qualifies primarily on property-level rental income covering the payment, subject to lender guidelines.
4. Pay the line down. Cash flow or a later cash-out refinance reduces the balance. A minimum subsequent draw of $1,000 applies if you reuse the line afterward.
Treat step 4 as required, not optional, because the line is a floating balance that keeps costing you until it is repaid. BiggerPockets frames the real test well: can the new rental cover its own mortgage, its operating costs, and the HELOC payment all at once? If the answer is no, the line is subsidizing the deal.
Our broader complete DSCR loans guide covers how the permanent-financing half of this plan is structured.
Where the General Rule Breaks
The rule above works until one of these edge cases shows up.
The rental sits in an LLC. Most investors hold rentals in entities. The line cannot. A property deeded to an LLC needs a vesting change, or you skip the HELOC and use a DSCR cash-out refinance (subject to lender program eligibility on LLC-titled borrowers).
Borrowed funds and the next lender. Whether a purchase lender accepts HELOC proceeds as a down payment depends on the program. Documenting the source of the funds and how long they sat in your account are the usual variables. Check the program before you assume either answer.
Someone else’s line. Using a relative’s HELOC for your down payment tends to hit documentation walls. Treat it as a red flag until a lender confirms in writing.
The line shrinks. The CFPB’s HELOC booklet explains that credit limits are set as a percentage of home value minus the mortgage balance. Lenders can reduce a line if the value falls. A line you were counting on for a second draw may not be there.
Listing history. In several states, a property listed for sale within the past 60 days is ineligible. If you are weighing a sale of the first rental, this can close the door.
Your home is on the line. The CFPB’s overview of HELOCs warns that missed payments can cost you the property securing the line. Here, that property is your rental.
Long holds versus short holds. A line suits a purchase you plan to refinance out of. It is a poor permanent down payment on a 30-year hold, because you are paying on a floating balance for years.
HELOC Down Payment vs. DSCR Permanent Financing
For most rental buyers, the HELOC is the down-payment bridge and the DSCR loan is the permanent financing. They solve different problems. A line is a personal credit decision against your equity. A DSCR loan reads the new property’s rent against its own monthly obligation.
| Factor | Investment-property HELOC | DSCR purchase loan |
|---|---|---|
| What it is reviewed on | You and your equity | Property rent vs. its payment |
| Typical leverage | 70% CLTV ceiling | 75%-80% LTV on most files |
| Higher-leverage option | Not available | 85% LTV with roughly a 700+ score |
| Credit | 700 minimum | 620 floor in parts of the network; most want about 660 |
| Entity ownership | Individual or revocable trust | LLC possible, per lender program requirements |
| Loan size | $25,000-$500,000 | Up to $3,000,000 on standard programs |
DSCR coverage compares rent with principal, interest, taxes, insurance, and any association dues, known together as PITIA. Select programs start at 1.00. Stronger coverage opens better pricing and leverage. A separate select-lender path accepts coverage below 1.00, with leverage and terms adjusted.
Don’t confuse clearing the ratio with making money. Repairs, vacancy, management, utilities, and capital expenses all sit outside the calculation. A property at 1.20x can still lose money in a bad month.
Reserves also work differently here. DSCR programs commonly ask for around 6 months of PITIA, though they vary by lender, leverage, loan size, and transaction type. Modest-leverage rate-and-term files under $1,500,000 may see reserves waived, and loans above that size typically step up to about 9 months.
Compare leverage honestly. If you buy at 80% LTV on the DSCR loan and fund the down payment from a HELOC, the two together can cover close to the full price. Your equity in the new property is thinner than it looks. This is the part many first-time investors skip. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
If the next purchase is later cash-out refinanced, expect a ceiling around 75% LTV across most of the network and about 6 months of seasoning. For a side-by-side look at the alternative route, Lendmire’s piece on using an investment property HELOC versus a DSCR cash-out refinance on one rental to buy the next goes deeper. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
Does the Next Rental Carry the Line?
Before you apply, run the stress test. Three questions settle it.
- Can the new property’s rent cover its own payment? That is the coverage number a DSCR lender will check.
- Can your cash flow absorb the line’s payment on top? The draw period is interest-only. That is a good deal early and a trap later.
- What happens when the 25-year repayment period begins? The payment steps up as principal amortizes. Plan for it on day one.
Then add vacancy. A month with no tenant on either rental still leaves two payments due. The investors who get through that are the ones with reserves beyond the minimum.
Honestly, this is a close call for many first-time buyers. The line makes the purchase possible, but it also ties two properties together. Whether that tradeoff is worth it depends on how much equity cushion you keep and how thin the new deal’s coverage is.
Key Terms Defined
HELOC: A revolving line of credit secured by a property, which you can draw on, repay, and draw on again during the draw period.
CLTV: Combined loan-to-value, the total of your first mortgage and new line divided by the property’s value.
Draw period: The stretch when you can borrow from the line and usually pay only interest. On investment lines here it lasts 5 years.
Repayment period: The stretch after the draw period when you repay principal and interest. On investment lines here it lasts 25 years.
DSCR: Debt service coverage ratio, a property’s monthly rent divided by its monthly PITIA.
PITIA: Principal, interest, taxes, insurance, and association dues, the full monthly obligation on a property.
Seasoning: The waiting period a lender wants between events, such as owning a property before a cash-out refinance.
Frequently Asked Questions
Can I use a HELOC on one rental to buy another investment property?
Yes, if the line itself is approved. You qualify for the line on your own credit and equity, then use the funds for the next purchase. A separate lender approves that purchase on its own rules, and many investors use a DSCR loan for it.
Does the line need an appraisal?
Usually not. Because investment lines cap at $500,000, they ordinarily run on an automated valuation. A higher CLTV may require a secondary valuation, and you can request a full appraisal if you want one.
Can an LLC take out an investment property HELOC?
No. Title must be held by you or a revocable living trust. If your rental is deeded to an LLC, it needs a vesting change before a line, or a DSCR cash-out refinance can work instead.
Can I keep the line undrawn until I find a deal?
Not on these lines. At least 75% of the line is drawn at closing, so you carry most of the balance from the start. Plan the timing of the line around the purchase, not ahead of it.
Will the HELOC payment hurt my DSCR on the next property?
Not directly. A DSCR loan compares the new property’s rent with its own payment. The line affects your personal cash position and the first rental’s cash flow, though a given program may count it differently, so check before you commit.
