The Quick Read: The right HELOC provider for your third purchase depends on which property secures the line, how much equity remains after your existing liens, and your credit profile, and because lines on rentals are a narrower product, a broker that shops several wholesale lenders can match your file to the program that fits. This article names no lenders, because the answer changes with your file. It explains the provider types, how underwriting treats the line, and when a DSCR loan (a loan reviewed mainly on the rent a property earns against its own payment) does the job better.
- The line can sit on your home or on a rental, and the choice changes the leverage cap, the credit floor, and your risk.
- On this network, an investment-property line tops out at 70% CLTV, while 90% exists only on primary-residence and second-home lines at a 720 credit profile or better.
- A HELOC is judged on your personal debt-to-income ratio, so it gets harder to pass as you add properties.
- The HELOC payment sits outside the rental’s DSCR, but it still has to be paid from your cash flow.
- A rental held in an LLC cannot hold the line, which often points an investor toward a DSCR cash-out refinance instead.
What Does a HELOC Do When You Buy a Third Property?
A home equity line of credit (HELOC) lets you borrow against equity you already hold, then use the cash as the down payment on property number three. Equity is what the property is worth minus what you owe on it. You draw cash, put it into the purchase, and a separate loan finances the rest.
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 line has two phases. During the draw period, you borrow up to your limit and usually pay interest only. After that, the repayment period begins, and you pay down principal as well. The payment steps up when that switch happens, so plan for it from the start.
Lenders measure the line with CLTV, which stands for combined loan-to-value. It adds up every loan against the property, including the first mortgage and the new line, and divides by the property’s value. A 70% CLTV cap means all loans together cannot exceed 70% of value.
For a third purchase, the HELOC is only half of the structure. The purchase loan has its own approval. Most scaling investors pair the line with a DSCR loan for that second half, and the sections below show how the two fit together.
Which Types of Providers Write These Lines?
Four kinds of providers write equity lines: large retail lenders, local credit unions, online lenders, and brokers with a wholesale network. They differ more in how they underwrite rentals than in anything else. Large retail lenders and credit unions mostly work from their own menu. Online lenders run narrower programs. A broker works across several wholesale lenders and matches the scenario to a program.
| Provider type | Who it suits | What to ask |
|---|---|---|
| Large retail lender | Existing customers with simple files | Does it write lines on rentals at all? |
| Local credit union | Members with a primary-home line | Is title in an LLC or trust allowed? |
| Online lender | Borrowers with a narrow, standard file | What is the CLTV cap by occupancy? |
| Broker with wholesale network | Borrowers with several financed properties | Which program fits my equity and credit? |
Many large retail lenders do not write lines on rental property, and those that do tend to apply tighter limits than they do on a primary home. That is why the best provider for your situation is a question about fit, not a ranking.
Lendmire is a mortgage broker, not a lender. It arranges equity lines through select wholesale partners. This HELOC product is available in Lendmire’s 16 full-service states, which is narrower than its 41-market DSCR footprint of 40 states plus Washington, D.C. The partner lenders decide eligibility, and every figure here is subject to lender guidelines and a full file review.
Which Property Should Secure the Line?
You can secure the line with your primary home, a second home, or a rental you already own. The collateral sets the leverage cap, the minimum credit score, and the maximum line, so it is the most important choice you make.
| Collateral | Max CLTV | Minimum credit | Max line |
|---|---|---|---|
| Primary residence | 90% (at 720+) | 600 | $500,000 at 90% CLTV; $750,000 at 75% CLTV, 700+ (720 on the longer-runway program) |
| Second home | 90% (at 720+) | 640 | $500,000 |
| Investment property | 70% | 700 | $500,000 |
The 90% ceiling exists only at a 720-or-better credit profile, and only on lines up to $500,000. Lower scores step the cap down. On a primary residence, for example, a 640 profile reaches 80% CLTV, and a 620 profile reaches 70%. Investment-property lines stay at 70% CLTV for both qualifying tiers, 700 and 720 or better.
A line on your home puts your residence behind an investment bet. A line on a rental puts that rental at risk. The CFPB’s HELOC booklet warns that missed payments can cost you the property that secures the line. Pick the collateral you are most comfortable risking.
Title matters too. 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. If a rental is already deeded to an LLC, you need a vesting change first, or a DSCR cash-out refinance instead, subject to program terms.
How Does Underwriting Treat the Line, Step by Step?
Underwriting a HELOC is personal. The lender looks at your credit, your debt-to-income ratio (DTI), and your equity, not at the rent a property earns.
1. Collateral and title. The property must be eligible and held in an eligible vesting. Single-family homes, 2-4 units, PUDs, townhomes, and condominiums, including non-warrantable condos, are eligible. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not.
2. Credit. The program floor is 600, rising to 640 on second homes and 700 on investment properties. The score is a single-bureau score keyed to the primary wage earner. Programs also look at tradelines and housing history across all your financed properties.
3. Debt-to-income. The maximum is 50%, or 45% for credit profiles from 600 to 679. A ratio above 45% needs at least a 680 score. The lender reviews your file on the interest-only payment calculated on the maximum draw, not on what you plan to borrow.
4. Valuation. Lines at or below $500,000 ordinarily run an automated valuation instead of a traditional appraisal. A higher CLTV may require a secondary valuation, and you may request a full appraisal at any size. Every line above $500,000 requires one.
5. Sizing. The lender takes value times the CLTV cap, subtracts the liens already in place, and then limits the result by the dollar cap and by your DTI. The CFPB booklet describes the same basic formula: a percentage of the home’s value minus the mortgage balance.
6. Exposure. A borrower is limited to three lines. Combined exposure caps at $2,000,000 on a higher-leverage program and at $750,000 on a longer-runway program. Both are wholesale programs Lendmire places files with, and each figure applies only within its own program. A borrower with more than 15 financed properties is not eligible.
A bankruptcy needs four years of seasoning from discharge or dismissal. Foreclosure-family history splits by program. One seasons a foreclosure at seven years and a deed-in-lieu, pre-foreclosure, or short sale at four. The other declines that history regardless of age.
What Does the Equity Math Look Like?
The sizing formula is easier to see in percentages than in dollars. Assume a home worth 100% of its current value, with a first mortgage at 50% of that value. These are modeled assumptions, not market data.
- Primary residence at 720+, 75% CLTV tier: 75% minus 50% leaves room for a line worth up to 25% of value, before dollar caps and DTI.
- Investment property, 70% CLTV cap: 70% minus 50% leaves room for a line worth up to 20% of value.
Now see what a value drop does. Say the value falls 10% while the first mortgage stays put. On the investment property, the allowed total becomes 70% of 90%, or 63% of the original value. Subtracting the 50% first mortgage leaves room for a line worth only 13% of the original value, so a 10% drop in value shrinks the line by about 35%.
The first mortgage counts in full while the cushion shrinks. That is why a small price decline hits a line harder than the percentage the value fell. The CFPB booklet also notes that a lender may reduce or freeze a line if the home’s value falls substantially.
A lender may also value a recently bought property at the purchase price, and an automated valuation can come in below it. A rental you bought recently may therefore support less than you expected.
Draw Structures and Variations
Two draw structures exist on primary residences and second homes. One has a 3-year interest-only draw followed by a 17-year fully amortizing repayment. The other has a 5-year draw followed by a 25-year repayment. Investment lines run the 5-year/25-year structure only.
Three other features shape a third-property plan:
- At least 75% of the line is drawn at closing. This is not a draw-as-needed product, so size it to the down payment you actually need.
- Pricing floats through both the draw and the repayment period and never converts to fixed. The CFPB describes a HELOC as an open-end line with a draw period and then a repayment period, often over ten or 20 years.
- Lines run $25,000 to $750,000. A line above $500,000 is primary-residence only, requires a 700 credit profile or better (720 on the longer-runway program), caps at 75% CLTV, and requires a full appraisal.
The line can sit in first or second lien position as a standalone loan. If you already carry a line and a first mortgage, a new line becomes a third lien, which narrows the field further.
How Does the HELOC Pair With the Purchase Loan?
The HELOC funds the down payment. A DSCR loan finances the purchase. It qualifies primarily on property-level rental income covering the payment, subject to lender guidelines, so your growing DTI does not block it. The complete DSCR loans guide walks through the full program.
Across the network, most DSCR purchase files land at 75% to 80% LTV, which means 20% to 25% down. Select programs reach 85% LTV, or 15% down, with roughly a 700+ score. Financial media also note that investment purchases may need a larger down payment of 15% or more. Coverage of 1.00 is where many select programs start, and stronger ratios open better pricing and leverage. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
Two points trip up first-time stackers.
The HELOC payment is not in the DSCR. The ratio compares rent to the property’s own payment: principal, interest, taxes, insurance, and any association dues, together called PITIA. The line’s payment sits outside it. Clearing 1.00 also does not mean positive cash flow, because repairs, vacancy, management, utilities, and capital expenses fall outside the calculation.
Borrowed down-payment funds get their own review. The purchase lender decides whether borrowed money is acceptable. Such funds are commonly accepted with documentation but are often left out of reserve counts. Reserves are the months of payments you must hold in liquid assets, and they vary by lender, leverage, loan size, and transaction type. Commonly the figure is around six months of PITIA.
You must also carry the first mortgage, the line, and the new loan together. As Benzinga notes, you need to cover all three payments at once. Stress-test the line’s payment at the full drawn balance and at the amortizing step-up, not just at the interest-only stage. Lendmire’s piece Top Investment Property HELOC Providers for Investors Buying More Rentals goes deeper on stacking.
A typical sequence runs in this order: line approved, funds drawn, purchase file submitted with the source of funds documented, and then closing. Get the order right, because the purchase lender will want to see where the down payment came from.
Where the General Rule Breaks
The general rule says an investor with equity can borrow against it. These edge cases bend that rule.
A rental already in an LLC. The line cannot be held by an LLC, so the property either needs a vesting change or a different tool. A DSCR cash-out refinance fits here. It tops out around 75% LTV across most of the network, with about six months of seasoning as the common expectation. Seasoning is the waiting period between buying a property and refinancing it. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
Converting your home into a rental. Renting out the home that secures a line may be prohibited under the line’s terms, according to the CFPB booklet. If your plan is to move out and rent it, check before you draw.
A listed property. In some states, a property listed for sale, or listed within the past 60 days, is ineligible. Check this before you pull equity from a house you are thinking of selling.
Property types. DSCR financing through the network is not offered on manufactured homes (single- and double-wide), log homes, or barndominiums. A HELOC does not work for those either.
A line above $500,000. It is available only on a primary residence, at 75% CLTV, with a full appraisal. It cannot go on a rental.
Credit events. A recent bankruptcy, or foreclosure history on a program that declines it, ends the conversation on that program regardless of equity.
Tax assumptions. 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.
When Is a HELOC the Wrong Tool?
A HELOC is the wrong tool when your DTI is already stretched, when the rental sits in an LLC, or when a floating payment would squeeze a property that is still leasing up. Two alternatives often fit better.
| Option | What it is | Fit |
|---|---|---|
| HELOC | Revolving line, floating payment | Down payment from home equity |
| Home equity loan | Fixed lump sum, per the CFPB | Known one-time cash need |
| DSCR cash-out refinance | New loan replacing the first | Rental in LLC; large equity pull |
A home equity loan gives a fixed lump sum, as the CFPB explains. A cash-out refinance replaces your first mortgage instead of adding a second. It allows LLC title, subject to lender program eligibility.
The stronger play is usually the one where both tests are cleared: enough equity and enough rental coverage. A larger down payment lowers the monthly obligation and can lift the DSCR. It never erases leverage caps, credit floors, reserve rules, or property eligibility.
Key Terms Defined
HELOC: A revolving line of credit secured by a property, with a draw period followed by a repayment period.
CLTV: Combined loan-to-value, the total of all loans against a property divided by its value.
DSCR: Debt service coverage ratio, the property’s monthly rent divided by its monthly PITIA.
PITIA: Principal, interest, taxes, insurance, and association dues, the full monthly payment on a property.
Seasoning: The waiting period a lender requires after a purchase before it allows a refinance.
Reserves: Liquid funds, counted in months of payments, that a lender wants you to hold after closing.
DTI: Debt-to-income ratio, your monthly debts divided by your monthly income.
Frequently Asked Questions
Can I get a HELOC on a rental I already own?
Yes, on an eligible rental, but the terms are tighter than on a home. On this network, an investment-property line caps at 70% CLTV, requires a 700 credit profile or better, and tops out at $500,000. The rental must be held by you individually or in a revocable living trust, not an LLC.
Can I use HELOC money as the down payment on my third property?
Usually, but the purchase lender makes its own decision. Borrowed funds are commonly accepted with documentation, and they are often excluded when the lender counts reserves. Confirm the purchase lender’s source-of-funds rules before you draw.
Does the HELOC payment count against my DSCR?
No. The DSCR compares rent to the property’s own PITIA. The line’s payment sits outside that ratio, but you still pay it from your cash flow, and it counts in the DTI the line itself is underwritten on.
What is the highest CLTV I can reach?
It depends on the occupancy. The investment-property ceiling is 70% CLTV. Primary-residence and second-home lines reach 90% CLTV, but only at a 720-or-better credit profile and only on lines up to $500,000.
Is a HELOC better than a DSCR cash-out refinance?
Neither wins in every case. A HELOC leaves your first mortgage alone and adds a floating second loan. A DSCR cash-out replaces the first loan, allows LLC title subject to program terms, and is reviewed on the property’s rent.
