Investment Property HELOC Rules for Borrowing on Your Rental

The Quick Read: A line of credit secured by a rental is a narrow product. Through select lenders in Lendmire’s wholesale network, it caps at 70% combined loan-to-value on an investment property, requires a 700 credit score, tops out at $500,000, and must be titled in an individual’s name or a revocable trust. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.

• The 70% ceiling counts your first mortgage and the new line together, so existing debt shrinks the line.
• Credit above 700 buys eligibility, not extra leverage, because 720 and 700 reach the same 70% ceiling.
• Qualification runs on the borrower’s credit, debt-to-income ratio and equity, not on the property’s rent coverage.
• An LLC cannot hold title on these lines, which is the sharpest difference from a DSCR loan.
• Every figure is subject to lender guidelines and full file review.

Key Terms Defined

HELOC: A home equity line of credit is a revolving credit line secured by property, with the limit tied to your equity.

CLTV: Combined loan-to-value adds the first mortgage and the new line, then divides by the property’s value.

Draw period: This is the stretch of time when you can borrow against the line, usually with interest-only payments.

Repayment period: This is the stretch after the draw ends, when the balance amortizes and payments step up.

DSCR: The debt service coverage ratio is monthly rent divided by the monthly principal, interest, taxes, insurance and any HOA dues. DSCR loans are built on that ratio, and HELOCs are not.

What Are the Rules at a Glance?

On this network, an investment property line is a standalone line in first or second lien position. It follows one structure only.

No federal rule sets investment-line LTV, credit or DTI limits. Each lender writes its own guidelines, and those guidelines are what this table summarizes. Pairing the 700 score with the 70% ceiling matters. Lines on a primary residence or second home can reach higher CLTV, and a 90% ceiling appears only at a 720-or-better credit profile. Those figures never describe a rental.

How Does Underwriting Treat a Rental Line, Step by Step?

Underwriting looks at the borrower first and the building second. A DSCR loan reverses that order. The sequence below is how most lines in the network are reviewed.

1. Collateral and lien position. The rental secures the line, and it can sit behind an existing first mortgage or in first position.

2. Equity test. The lender adds the first mortgage balance to the new line and compares the total to the property’s value. That result must stay at or below 70%.

3. Credit. The network uses a single-bureau score keyed to the primary wage earner, with a 700 floor on investment lines. The report can be no more than 90 days old at closing.

4. Income and debt-to-income. The maximum DTI is 50%. The lender reviews your file on the interest-only payment calculated as if the full line were drawn.

5. Valuation. An investment line cannot exceed $500,000, and full appraisals are required only above that size. So these files normally run an automated valuation, though a borrower may request a full appraisal. A higher CLTV can also trigger a second valuation.

6. Eligibility. The lender checks property type, vesting, borrower exposure and any recent credit events.

Some lenders credit part of the rent toward qualifying income, and practices vary. Even so, the review remains borrower-based. Rent coverage does not decide the file the way it does under a DSCR loan.

How Much Can You Borrow? A Worked Example

The line equals 70% of value minus the first mortgage, up to the $500,000 cap. The example below uses percentages of value so it works at any price. The 45% first mortgage is a modeled assumption, not market data.

On a high-value free-and-clear rental, the $500,000 cap binds before the equity test does. On a mortgaged rental of moderate value, the equity test binds first. Two rentals with the same value can borrow very different amounts, so the first mortgage balance is the number to know before you apply.

How Do the Draw and Repayment Periods Work?

During the draw, the line behaves like a revolving account and payments are interest-only. The CFPB’s HELOC explainer describes the same cycle: you borrow during a draw period, then move into a repayment period, often over ten or twenty years.

On investment lines in this network, the draw runs five years and repayment runs twenty-five years, fully amortizing. Pricing floats through both periods and never converts to a fixed structure.

Two details change how the line behaves in practice. First, at least 75% of the line must be drawn at closing, so this is not a dormant standby account. You carry most of the balance from day one. Second, the step-up at the end of the draw is real. A balance used to buy another property can hit repayment before that property has stabilized. The CFPB’s HELOC booklet also notes that lenders can charge fees, including appraisal fees, so ask for the full fee schedule before you compare lines.

Where Does the General Rule Break?

The 70% and 700 figures are the baseline. These edge cases change the answer even when your credit and equity look fine.

An LLC holds title. The line cannot go on a property titled in an LLC, corporation, partnership, or an irrevocable, blind or land trust. A property already deeded to an LLC needs a vesting change or a different product. A DSCR cash-out refinance can be held in an LLC, subject to lender program eligibility. Check lender appetite before any deed transfer.

The rental still carries a mortgage. Many banks decline these. The network allows a second-lien line behind an existing mortgage, which is the usual structure. How a bank treats the question depends on its own product design.

You own several properties. A borrower is limited to three lines in total. A borrower with more than 15 financed properties is not eligible. If you own a large portfolio, you will probably hit a cap before you run out of equity.

The property type is wrong. 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, mixed-use and agricultural-zoned properties are not.

Credit events are on the report. 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 state adds conditions. Lendmire offers equity lines in 16 full-service states, which is narrower than its DSCR footprint of 40 states plus Washington, D.C. Within those states, a property listed for sale, or listed within the past 60 days, is ineligible in six of them. New Mexico and Ohio also tie the CLTV cap to the credit profile.

The lender pool is small to begin with. One BiggerPockets thread describes these lines as hard to find and advises calling the smallest local banks and credit unions.

HELOC, Cash-Out Refinance or DSCR Loan?

The right tool depends on title, size and how the rental is documented. The table compares the three realistic paths.

The primary-home line is the only one that avoids putting the rental at risk. It puts your residence at risk instead. A DSCR cash-out refinance on a standard rental tops out around 75% LTV, with about six months of seasoning as the common expectation. A short-term rental caps at 70% on a cash-out. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.

DSCR works differently from a HELOC. It compares the property’s rent to its full monthly obligation. A coverage ratio of 1.00 is where many select programs start, and a separate select-lender path takes coverage below 1.00 with leverage and terms adjusted. Clearing 1.00 does not mean the property produces positive cash flow. Repairs, vacancy, management, utilities and capital expenses sit outside the calculation. The same equity and credit file can look very different through each lens. For the full mechanics, see the complete DSCR loans guide.

If you want a small, flexible line on a personally titled rental, the investment HELOC fits. If the property sits in an LLC, if you want more than $500,000, or if you would rather not be tested on personal DTI, the DSCR cash-out is the more natural path.

What Are the Risks, and How Do You Stress-Test the Line?

The line’s two biggest risks are pricing that floats and a draw period that ends. Before drawing, run these checks.

• Model the interest-only payment on the full line, since that is how the lender qualifies you.
• Model the amortizing payment that begins when repayment starts, and confirm the rental can carry it.
• Test a vacancy period and a drop in rent against the combined payment on the first mortgage and the line.
• Confirm you can meet the payments on the line even if the new property is not yet producing income.
• Plan for the lien. Missed payments put the rental at risk, and the line adds to your total debt load.

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.

What Does the Decision Look Like in Practice?

Start with title and size. If the rental is in your own name or a revocable trust, and your need is under $500,000, the investment line is a legitimate option. If you hold it in an LLC, or your need is larger, skip to the DSCR cash-out.

Then check whether you clear both tests: 70% CLTV on the equity side and a 700 score on the credit side. If your first mortgage is large, the line may be too small to be worth the fees. If you plan to use proceeds on another rental, remember that at least 75% of the line is drawn at closing and starts costing you immediately.
