The Quick Read: A home equity line of credit (HELOC) lets you borrow against equity in a property you already own and use the cash toward the down payment and closing costs on the next rental, but the line and the purchase loan are two separate approvals, and each one has its own rules about leverage, credit, and sourcing.
- On Lendmire’s wholesale network, an investment-property line tops out at 70% combined loan-to-value (CLTV) and $500,000, with a 700 minimum credit score.
- The purchase loan is usually a DSCR loan, which looks at the new property’s rent against its own housing payment, not at your HELOC.
- The HELOC payment still comes out of your pocket, so clearing the coverage test does not mean the deal cash flows.
- Whether the purchase lender accepts borrowed money as your down payment varies by program, so ask before you draw.
- HELOCs on investment property are offered in Lendmire’s 16 full-service states, a narrower footprint than the DSCR platform.
What Is an Investment Property HELOC?
An investment property HELOC is a revolving line of credit secured by a rental you own. You borrow against equity, which is the property’s value minus what you owe on it. You can use the money for whatever you like, including the next acquisition.
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 product is rarer than the owner-occupied version. NerdWallet notes that not every lender offers a HELOC on investment property and that those who do apply stricter standards, including more than one appraisal in some cases. Market surveys also report higher credit expectations and lower leverage limits than on a primary home. On Lendmire’s network, the investment-property ceiling is 70% CLTV, and the line is capped at $500,000 in total.
The appeal is simple. You keep your existing first mortgage in place and pull cash from the equity you’ve built. That makes the strategy popular with owners who bought well, held for a while, and now see a second deal.
Two Separate Approvals, Step by Step
The line and the purchase loan never merge. Each lender judges its own loan on its own terms.
Step 1: the line is underwritten to you and the collateral. The lender reviews your credit, your equity, your existing liens, and your debt load. On the network’s investment line, the maximum debt-to-income ratio is 50%. 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 if you only intend to use part of the line.
Step 2: the draw. At least 75% of the line is drawn at closing. That surprises many owners who expect a flexible account they can tap in small pieces. Because most of the line is drawn up front, you begin carrying the cost on most of it right away. A $1,000 minimum applies to later draws on most files. The line’s pricing is variable and never converts to fixed.
Step 3: the purchase loan. This is a separate application, usually a DSCR loan on the new property. DSCR stands for debt service coverage ratio, which is the property’s monthly rent divided by its monthly principal, interest, taxes, insurance, and any HOA dues (together called PITIA). The loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. Your HELOC payment is generally not part of that ratio. It still matters to your cash, your credit file, and your reserves.
One more point on valuation. Because an investment line is capped at $500,000, it commonly runs on an automated valuation rather than a full appraisal, though a higher CLTV can trigger a second valuation, and you can always request a full appraisal.

Which Property Should Secure the Line?
You have two options, and they carry different risks. Lenders generally find a primary residence easier to approve, but pledging it puts your home on the line. Pledging an existing rental keeps the risk inside the investment portfolio, but fewer lenders will touch it.
| Factor | Line on Primary Home | Line on Existing Rental |
|---|---|---|
| Lender availability | Wider | Narrower |
| What is at risk | Your residence | A rental asset |
| Network CLTV ceiling | Higher tiers, occupancy-specific | 70% CLTV, 700+ credit |
| Title | Individual or revocable trust | Individual or revocable trust |
The network’s primary-residence tiers reach 90% CLTV, but only at a credit profile of 720 or better, and they do not apply to an investment line. If you are asking about a rental, the ceiling is 70%.
Here is the arithmetic in percentages. Say your rental’s first mortgage already uses 50% of its value. At a 70% combined ceiling, the line can use at most 20 points of value, and the $500,000 cap applies on top of that. A heavily financed rental may leave little or nothing to draw.
How the DSCR Lender Treats the Draw
The purchase lender decides what counts as acceptable down-payment money. Treatment varies by program across the network. Some accept a documented HELOC draw. Others want a minimum from your own unborrowed funds. A few look hard at how much of the cash is borrowed.
Reserves are a separate pot. Reserves are the cash you hold after closing, commonly around 6 months of PITIA, though that varies by lender, leverage, loan size, and transaction type. Many programs want those reserves to be your own sourced funds, so HELOC cash may not serve double duty.
Expect the purchase lender to request:
- the HELOC closing documents and the draw confirmation
- statements showing the cash landing in your account
- a credit report that shows the new line as a liability
- the usual property file: lease or rent schedule, appraisal, and insurance
Purchase leverage works as it normally does. Most DSCR purchase files land at 75%-80% LTV, which means 20%-25% down. Select programs reach 85% LTV with roughly a 700+ score. Coverage 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 coverage opens better pricing and higher leverage.
Across Lendmire’s wholesale network, the files that stumble here usually skip one question: will this specific purchase lender accept borrowed funds? Asking before you go under contract avoids an expensive surprise.
Stacked Payments: Where the Deal Really Lives
Picture an investor who draws on an existing rental and buys a second duplex with a DSCR loan. The new duplex’s coverage clears roughly 1.2x. On paper, great.
Now look at what is actually happening. The new property’s rent covers its own payment. The HELOC payment, though, has to be covered by something else, such as the old rental’s cash flow or your salary. If the new unit sits vacant for a while, two obligations depend on the same pool of money.
DSCR compares rent to PITIA only. Repairs, vacancy, management, utilities, and capital expenses sit outside the calculation. Clearing 1.00x is not the same as positive cash flow.
That is why a go/no-go check should include a stress test. Cut the new rent by a month or two per year. Add the HELOC payment. See whether you can carry both without touching reserves.
Where the Rule Breaks
The general rule is that a HELOC against one property can fund the next. These edge cases bend it.
LLC title. Lines on the network require the borrower to hold title as an individual or in 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 can look at a DSCR cash-out refinance instead, which can lend to an LLC subject to lender program eligibility.
A line on the property you are buying. You have to own it first. That makes it a post-purchase tool, not a down-payment source.
First-lien lines. The network’s standalone line can sit in first or second lien position. A first-position line replaces your existing mortgage, which is a different decision from adding a second lien beside it.
A parent’s or partner’s HELOC. Someone else’s line generally cannot be treated as your own money. Many programs would treat it as a gift, and gift rules vary by lender.
Quick-turn strategies. Some investors plan to repay the line by refinancing a rehabbed property. That works only if the appraisal and the refinance timing cooperate. Otherwise you carry both loans longer than planned.
Frozen or reduced lines. The CFPB’s HELOC booklet explains that lenders may freeze or reduce a line if property value falls or your finances worsen. Undrawn credit is permission to borrow, not committed cash, and it generally does not count as an asset. The CFPB also warns that falling behind on payments can put the collateral at risk.
Ineligible property types. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agriculturally zoned property are not eligible for the line. Single-family homes, 2-4 unit properties, PUDs, townhomes, and condominiums, including non-warrantable ones, are eligible. Manufactured homes, log homes, and barndominiums are also not offered on the DSCR purchase side.
Portfolio size. A borrower is limited to three lines, and an owner of more than 15 financed properties is not eligible.
Should You Do It? A Decision Checklist
Use this before you apply.
1. Equity. After your first lien, is there enough room under a 70% CLTV ceiling to matter?
2. Credit. Is your score at 700 or better? There is no tier beneath that on an investment line.
3. Purchase lender. Has the DSCR lender confirmed it accepts a HELOC draw as down-payment funds?
4. Cash flow. Can you carry the line payment if the new property sits empty?
5. Reserves. Will you still have your own sourced reserves after the down payment and closing costs?
6. Exit. Do you have a plan for repaying the line that does not depend on a single refinance landing perfectly?
If any answer is no, slow down. A line is a good tool for covering a short timing gap on a deal that already works. It is a poor tool for propping up a deal that doesn’t.
Tax treatment can depend on how the funds are used and how the property is held; investors should keep clear records and speak with a qualified tax professional before relying on any deduction. Keeping the draw in a dedicated account makes those records easier.
HELOC or Something Else?
Sometimes the better fit is a different product. Here is how the main options compare.
| Option | Structure | Best for |
|---|---|---|
| Investment HELOC | Revolving line, 70% CLTV ceiling | Keeping the first mortgage |
| DSCR cash-out refinance | Replaces the existing loan | Larger equity pulls |
| Home equity loan | Closed-end, fixed amount | One-time, known need |
A DSCR cash-out refinance on a rental generally tops out around 75% LTV on a standard rental, with about 6 months of seasoning as the common expectation. For short-term rentals, cash-out is typically around 70%. Cash-out replaces your existing loan, so it is worth running if your current first mortgage is not one you want to protect. Lendmire’s piece Investment Property HELOCs for the Landlord Sitting on a Low Mortgage covers that tradeoff in detail. If your traditional personal-income documentation understates your rental income, Lendmire’s piece Investment Property HELOCs for Landlords Whose Returns Understate Income explains the documentation path.
Short-term rental rules can vary by city, county, HOA, and property type, so investors should confirm local rules before relying on projected rental income.

Lien position: Whether a loan gets repaid first (first lien) or after another loan (second lien).
Frequently Asked Questions
Can I use a HELOC as the down payment on another rental?
Often, but it depends on the purchase lender. Some DSCR programs accept a documented HELOC draw. Others require a minimum from your own unborrowed funds. Ask the purchase lender before you draw, and keep the paper trail from line to account to closing.
Does the HELOC payment count against my DSCR?
Generally not. The coverage ratio looks only at the subject property’s rent and PITIA. The HELOC payment still affects your credit file, your cash, and your reserves, so it matters to the overall picture even though it sits outside the ratio.
Can my LLC take out an investment property HELOC?
Not on this network. The line requires title in an individual’s name or a revocable living trust. A property held by an LLC needs a vesting change first, or a DSCR cash-out refinance may be the more natural way to pull equity.
How much can I borrow against a rental?
Up to 70% CLTV on an investment property, a $500,000 maximum line, and a 700 minimum credit score. Your existing first mortgage counts toward that 70%, so heavily financed rentals may leave little room. All figures are subject to lender guidelines and full file review.
Will the lender freeze my line if the market softens?
It can. Lenders may freeze or reduce a line when property value falls or your finances worsen. Do not plan a purchase around credit you have not yet drawn.
