The Quick Read: An investment property HELOC works as a standalone line secured by a rental, sized by combined loan-to-value rather than by rent, and on Lendmire’s wholesale network it caps at 70% CLTV, so a property with 30% equity today has no room while one that keeps 30% equity after the line fits right at the ceiling.
- The ceiling on an investment line is 70% CLTV. Credit above 700 buys eligibility, not extra leverage.
- Lines run from $25,000 to $500,000, in first or second lien position, with a 5-year interest-only draw and a 25-year repayment period.
- The borrower is underwritten on credit and debt-to-income, not on the property’s rent coverage.
- The rental must be titled in an individual’s name or a revocable living trust. An LLC cannot hold title.
- Whether 30% equity is enough depends on how much of it your existing mortgage has already used.
Most investors hear the phrase 30% equity and assume they can borrow 30% of the value. That is not how the math runs. The lender adds your existing mortgage to the new line, divides by value, and compares the result to a cap. This article walks through that math, how underwriting treats the file, the structures that exist, and where the general rule breaks.
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.
What Does 30% Equity Actually Mean Here?
Thirty percent equity can mean two different things, and each leads to a different answer. Before you apply, work out which one describes your property.
Reading A: 30% equity remains after the line. Your total debt, existing mortgage plus the new line, equals 70% of the property’s value. That is exactly the ceiling on an investment line, so the line is just large enough to reach the cap.
Reading B: the property has 30% equity today. Your existing liens already equal 70% of value. Against a 70% ceiling, no room is left. The file does not fit until the first mortgage drops or the value rises.
The formula is the same in both cases. Take the property’s value, multiply by the CLTV cap, and subtract what you already owe. What remains is the most the line can be. If the result is zero or negative, there is no line.
CLTV counts the full credit limit, whether you draw it or not. A larger line eats more of the cap, even if you plan to use only part of it.
How Does an Investment Property HELOC Work?
An investment property HELOC is a revolving-style line secured by a rental. You borrow against it during a draw period, then repay during a longer repayment period. The CFPB’s HELOC booklet describes the basic design: once approved, you generally draw up to your limit, and a repayment period follows the draw period. That booklet was written for owner-occupied homes. The mechanics carry over, but the investment overlay is stricter on equity, credit, and title.
Across the wholesale network Lendmire brokers through, an investment line has these features:
- Size: $25,000 to $500,000.
- Lien position: a standalone line in first or second position. On a free-and-clear rental it can sit in first position.
- Structure: a 5-year interest-only draw followed by a 25-year fully amortizing repayment period. Investment lines run only this structure.
- Draw at closing: at least 75% of the line is drawn at closing.
- Pricing: it floats through both the draw and the repayment period and never converts to fixed.
The 75% draw requirement changes how you should think about the product. It works as a funding tool for a specific use, such as a down payment on the next rental, a rehab, or a debt payoff. It does not work as a standby reserve you open and leave untouched.
The floating pricing also matters for a rental’s cash flow. As the CFPB booklet explains, payments on a variable line can change even when you borrow nothing more. Then the repayment period starts, principal comes due, and the payment can step up sharply. An investor who sizes a line against a rental’s cash flow should model the repayment period, not only the draw period.
How Does Underwriting Treat the File, Step by Step?
Underwriting runs in a fixed order, and each step can end the file. Knowing the order tells you where to look first.
1. Eligibility of the property. The lender confirms the rental is an eligible type. Single-family homes, 2-4 unit properties, PUDs, townhomes, and condominiums, including non-warrantable condos, are eligible. Manufactured homes, co-ops, condotels, log homes, commercial and mixed-use properties, and agriculturally zoned property are not offered.
2. Title and vesting. The property must be held by the individual borrower or an inter vivos revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. Many investors lose the file at this step.
3. Valuation. Because an investment line tops out at $500,000, and full appraisals begin only above that size, an investment HELOC sits in the automated-valuation lane. It ordinarily closes with no traditional appraisal. A higher CLTV may call for a secondary valuation, and a borrower can request a full appraisal. NerdWallet notes that many lenders in the wider market may require multiple appraisals, so this lane is a real difference.
4. The CLTV test. Existing liens plus the proposed line, divided by value, must land at or below 70%.
5. Borrower qualification. This is the part that surprises DSCR investors. A HELOC is a personal-credit product. The minimum credit score on an investment line is 700, a hard floor with no tier below it. Debt-to-income runs to a 50% maximum. The lender reviews your file on the interest-only payment calculated on the maximum draw, so the whole line counts against DTI, not only what you take.
6. Credit history. A bankruptcy needs 4 years of seasoning from discharge or dismissal. On investment files, a foreclosure needs 7 years, and a deed-in-lieu, pre-foreclosure, or short sale needs 4. The credit report can be no more than 90 days old at closing.
One point on the credit tiers: 720 and 700 both reach 70% CLTV on an investment property. A higher score buys eligibility, not a bigger line. Business bank-statement income is never the binding constraint here either, since the 700 floor already exceeds the 680 minimum for the deposit analysis.
What Do the Numbers Look Like at Different Debt Levels?
The table below shows how much room a 70% CLTV ceiling leaves at different existing-debt levels. All figures are shares of the property’s value, so they work for any price.
| Existing liens (% of value) | Equity today | Room under 70% cap |
|---|---|---|
| 0% (free and clear) | 100% | Up to 70%, or $500,000 if lower |
| 40% | 60% | About 30% of value |
| 55% | 45% | About 15% of value |
| 65% | 35% | About 5% of value |
| 70% | 30% | — |
Look at the last row. A rental with exactly 30% equity today has nothing left to borrow under the investment ceiling. Now look at the second row: a property with 60% equity can support a line equal to 30% of value, and the borrower keeps 30% equity after the line. That is Reading A.
On a high-value free-and-clear property, the $500,000 maximum binds before the 70% cap does. Past that point, a bigger property does not produce a bigger line.
The calculator on this page gives an illustrative estimate of these relationships. It is a planning tool, not a quote.
Which Structure Fits at 30% Equity: HELOC, DSCR Cash-Out, or a Home Line?
At 30% equity, the right structure depends on which constraint binds first: equity, personal DTI, or title. Here is the side-by-side view.
| Factor | Investment HELOC | DSCR cash-out | Line on primary home |
|---|---|---|---|
| Sized on | Equity and borrower | Rent vs. payment | Equity and borrower |
| Existing mortgage | Stays in place | Replaced | Stays in place |
| Max leverage | 70% CLTV | About 75% LTV (standard rentals) | Higher; 90% CLTV only at 720+ |
| LLC title | Not allowed | May be allowed | Not applicable |
| Credit floor | 700 | Often about 660 | Varies by program |
A DSCR cash-out refinance on a standard rental tops out around 75% LTV across most of the network, with about 6 months of seasoning as the common expectation. It qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. A rental at 70% total debt today would leave roughly 5% of value of room before costs, and it replaces the first mortgage instead of sitting behind it. That is a real tradeoff if your first mortgage is one you want to keep.
Coverage of 1.00 is where many select DSCR programs start, and a separate select-lender path takes coverage below 1.00 with leverage and terms adjusted. A ratio at or above 1.00 does not mean a property produces positive cash flow, since repairs, vacancy, and management sit outside the calculation.
For an investor at 30% equity, the sorting rule is simple:
- If your first mortgage is small and your personal credit and DTI are strong, the HELOC adds capital without touching the existing loan.
- If title sits in an LLC, the HELOC is off the table unless you change vesting.
- If your personal DTI is stretched but the rental covers its own payment, a DSCR cash-out may fit better.
- If your equity is thin, neither works well and waiting may be the better move.
The primary-home alternative is the one most investors try first. Lines on a primary residence carry higher ceilings, reaching 90% CLTV only at a 720-or-better credit profile. The tradeoff is that the home becomes collateral for a rental decision. Lendmire’s piece Best Investment Property HELOC Program With 30% Equity in the Property covers that choice in more depth.
Where Does the General Rule Break?
The 70% rule is the general case. Several situations change the answer.
LLC-held rentals. This is the most common blocker. A rental already deeded to an LLC needs a vesting change before a line can sit on it, or it needs a DSCR cash-out instead. Retitling can raise insurance and loan-covenant questions of its own, so check those before moving a deed.
Recently purchased rentals. A rental bought with 20% to 25% down starts at 75% to 80% LTV. That is already above the 70% ceiling. Such a property has no room until the balance falls or the value rises. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
Free-and-clear rentals. With no first mortgage, nearly the whole 70% is available, up to the $500,000 maximum. The line takes first lien position.
Property-count limits. A borrower is limited to three lines at a time. An investor owning more than 15 financed properties is not eligible.
Ineligible property types. A manufactured home, a log home, or a co-op rental is not offered, regardless of equity. Barndominiums and agriculturally zoned parcels fall outside as well.
Naming and lender type. Large retail lenders vary widely on rentals. Some will not write a HELOC on a rental at all, but may offer a line of credit secured by investment property. Asking both ways costs nothing. The lender pool is narrow, which is a main reason investors use a broker with access to several wholesale lenders instead of one depository institution.
Availability by state. Lendmire’s equity-line placements are limited to its 16 full-service states. That is narrower than its 41-market DSCR footprint, so confirm availability early.
What Goes Wrong When You Sit at the Ceiling?
Sitting at exactly 70% leaves zero margin. If an automated valuation comes in below your expectation, the CLTV recalculates on the lower number. The line shrinks, or the file falls out.
Most investors who hit this wall make one of two mistakes. They anchor on the price they paid, or on a recent neighbor’s sale, instead of the value the lender’s model will produce. Or they request the maximum line when a smaller one would have fit with a cushion. Asking for a line 5% of value below the ceiling gives the valuation room to wiggle.
Test the file before you commit. Run it at your best value estimate, then again at a value several percent lower. If the second run fails, the line is too close to the edge.
A practitioner point on files like this: investors who stack a HELOC on a rental often discover too late that the pricing floats and the interest-only period ends. The line should be sized against the repayment period, not the draw period. Sizing to the payment that begins in year six is the safer way to read the product.
What Can You Do If the Numbers Don’t Fit?
A near-miss usually has a fix. These are the practical options, roughly in order of effort.
- Pay down the first mortgage. Every dollar of principal moves room back under the cap.
- Request a smaller line. A line sized under the ceiling can fit when the maximum does not.
- Wait for the value to rise. Appreciation increases equity without any new cash.
- Use equity from another property. A personally titled rental or a primary home with more equity may support the line instead.
- Move to a DSCR cash-out. If the rental covers its own payment, it can qualify primarily on property-level rental income, subject to lender guidelines. This route also works for LLC-held property.
- Change vesting. If the only problem is title, moving the deed to your name or a revocable trust can reopen the HELOC lane.
Many investors use a line as a bridge to permanent financing after a purchase or rehab.
What Should You Use the Funds For?
The best uses are ones that raise income or lower cost. Common choices include the down payment on the next rental, a rehab that supports higher rent, and paying off higher-cost debt. Each has a different risk profile.
A purchase down payment ties the new property’s performance to the line’s payment. A rehab depends on the work coming in on budget and on rents moving as planned. An improvement may support a higher appraised value, depending on comps and underwriter review, but it does not guarantee one.
Key Terms Defined
CLTV (combined loan-to-value): Your existing liens plus the new line, divided by the property’s value.
Equity: The property’s value minus all loans secured by it.
Draw period: The stretch when you can borrow from the line and pay interest only. On an investment line it runs 5 years.
Repayment period: The stretch after the draw period when principal and interest are both due. On an investment line it runs 25 years.
Lien position: Whether the line sits first or second in line behind other loans on the same property.
Vesting: The legal name in which the property’s title is held.
Automated valuation: A model-based value estimate used in place of a traditional appraisal.
Frequently Asked Questions
Can I get a HELOC on a rental with exactly 30% equity?
Not on this network’s investment lines. Exactly 30% equity means your existing liens already equal 70% of value, which is the ceiling, so no room is left. You would need to pay down the first mortgage, wait for appreciation, or pick a different structure.
Does rental income qualify me the way it does on a DSCR loan?
No. A HELOC is underwritten on your personal credit and debt-to-income, with a 700 minimum score and a 50% maximum DTI. Some lenders count part of a rental’s income when they calculate DTI, but the property’s coverage ratio does not drive the approval. A DSCR loan is the product that qualifies primarily on the rental’s income.
Can I hold the rental in an LLC and still get a line?
No. The property must be titled to you personally or to a revocable living trust. If the rental is already in an LLC, the options are a vesting change or a DSCR cash-out instead.
How much of the line do I have to draw?
At least 75% of the line is drawn at closing. Pricing then floats through the draw and repayment periods. Size the line to the amount you intend to use, not a larger limit you hope to leave idle.
Should I borrow against my own home instead?
It can offer higher ceilings, with 90% CLTV reached only at a 720-or-better credit profile. The cost is that your residence becomes collateral for a rental decision. If the rental underperforms, the exposure sits on the home. Compare that against a DSCR cash-out, which keeps the debt on the rental.
Next Steps
An investor with about 30% equity should do three things before applying. First, compute combined debt as a share of value. Second, confirm title is in a name the program accepts. Third, decide whether the personal-credit lane or the rent-based lane fits better. Lendmire’s complete DSCR loans guide explains the rent-based alternative in detail.
