How a HELOC Works or Home Equity Loan for Home Improvements

The Quick Read: A HELOC is a revolving line you draw on as improvement bills arrive, while a home equity loan pays one lump sum on a fixed schedule. Pick the line when costs are phased or uncertain, and the lump sum when the budget is fixed. Lenders qualify the borrower, the equity and the title, not the rent.

• A HELOC suits staged work; a closed-end home equity loan suits a known budget.
• The network’s investment-property equity line tops out at 70% CLTV, with a 700 minimum credit score.
• Primary-residence lines reach 90% CLTV only at 720 or better.
• LLC-titled rentals cannot carry these lines.
• Where the title or equity doesn’t fit, a DSCR cash-out refinance is the usual alternative.

Home improvements are where investors and homeowners meet the same question: borrow against equity in a line, or take a lump sum? The mechanics differ more than the marketing suggests. This guide walks through both, then shows where an investor’s situation breaks the usual rules.

What Is a HELOC, and How Does It Work?

A HELOC is a revolving credit line secured by your home. You are approved for a maximum, then borrow, repay, and borrow again during the draw period. The federal consumer-finance regulator’s 2014 HELOC booklet explains that the limit is generally set as a percentage of appraised value, minus what you still owe.

The life of a line has two phases:

1. Draw phase. You borrow as needed, usually with interest-only payments. Pricing on the lines we place floats and never converts to fixed.

2. Repayment phase. Borrowing stops. Principal and interest begin, and the payment can jump.

Payment shock at that switch is the main risk. Making principal payments during the draw phase softens it.

On the wholesale-network programs Lendmire works with, two structures exist for primary residences and second homes. One runs a 3-year interest-only draw followed by 17 years of repayment. The other runs a 5-year draw followed by 25 years of repayment. Investment lines use the 5-year draw and 25-year repayment structure only. Terms are subject to lender guidelines and full file review.

One feature surprises people. Across the network, at least 75% of the line is drawn at closing. It is not a pure standby line you leave untouched. After closing, the minimum additional draw is typically $1,000.

How Does a Home Equity Loan Work?

A home equity loan is a closed-end second mortgage. You receive the full amount at closing and repay on a fixed schedule. You cannot redraw as you pay it down.

That structure fits a project with a known price: a roof, a kitchen with a signed contract, an addition with a fixed bid. You know the number going in, and the repayment schedule doesn’t change.

The equity line described above is a different product with different underwriting. Always confirm which one a lender is actually quoting.

HELOC vs. Home Equity Loan: Side by Side

A project-matching rule of thumb helps. A signed-bid roof replacement points toward the lump sum. A whole-house rehab with contractors billing in stages points toward the line. Emergency repairs with an unknown scope point toward the line, with a modest draw first.

How Do Lenders Underwrite These Loans?

Underwriting runs in a predictable sequence. A thin step anywhere stops the file.

1. Equity. The lender sets a maximum combined loan-to-value (CLTV). Your first mortgage plus the new line cannot exceed that percentage of value.

2. Credit. The network’s program floor is 600 for primary residences, 640 for second homes and 700 for investment properties.

3. Debt-to-income. DTI is capped at 50%, and at 45% for profiles from 600 to 679. Qualification uses the interest-only payment on the maximum draw.

4. Valuation. Lines at or below $500,000 ordinarily use an automated valuation. A full appraisal is required above $500,000, and a borrower may request one at any size.

5. Title and vesting. The property must be held by the individual or a revocable living trust.

Notice what is missing: rent. A bank-style equity line reviews the borrower. A DSCR loan works the other way and qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. Our complete DSCR loans guide covers that approach in full.

How Much Can You Borrow? The Network Ceilings

Ceilings depend on occupancy and credit, so no single figure applies to everyone.

A few details matter. On a primary residence, a 700 score reaches 85% CLTV up to $500,000. A line above $500,000 requires 700 or better (720 on the longer-runway program), caps at 75% CLTV and needs a full appraisal. Only primary residences can borrow above $500,000, up to $750,000. Investment lines never exceed 70% CLTV or $500,000.

Availability is also narrower than the DSCR footprint. These equity lines are offered only in Lendmire’s 16 full-service states. A borrower can hold up to three lines, and anyone with more than 15 financed properties is not eligible.

Where the General Rule Breaks: Edge Cases for Investors

Several situations change the answer.

LLC title. LLCs, corporations, partnerships, and irrevocable, blind or land trusts cannot hold title on these lines. If your rental sits in an LLC, you would need a vesting change, or you would use a DSCR cash-out refinance instead, subject to lender program eligibility.

Property 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, and commercial, mixed-use or agricultural zoning are not offered.

Lender availability. NerdWallet notes that an investment-property HELOC is possible, but not every lender offers one and requirements are strict.

Derogatory history. A bankruptcy needs 4 years of seasoning from discharge or dismissal. Foreclosure history splits by program. One program seasons a foreclosure at 7 years and a short sale or deed-in-lieu at 4. The other declines that history entirely.

Title naming. Some lenders won’t write a HELOC on a non-owner-occupied property but will offer a similar secured line under another name. Ask what the product is called and how it is secured.

Using your own home’s line on a rental. This is legal to attempt with disclosure to the lender, but the equity sits against your home. The risk of losing that home rises if the rental underperforms.

The Investor Decision in Practice

The real choice for an investor is rarely line versus lump sum. It is usually second lien versus replacing the first lien.

A second lien leaves your existing first mortgage in place. That helps if the first loan is attractive. But the new line floats, and the payment can change as pricing moves.

A DSCR cash-out refinance replaces the first lien. It qualifies primarily on rental income covering the payment, subject to lender guidelines. Across most of the network, cash-out refinance tops out around 75% LTV on a standard rental, with roughly 6 months of seasoning commonly expected. DSCR loans for standard rentals commonly start at a 1.00 coverage floor, with stronger ratios opening better pricing and leverage. A select-lender path takes coverage below 1.00, with leverage and terms adjusted.

Keep in mind that DSCR compares rent to PITIA only. Clearing 1.00 is not the same as positive cash flow, since repairs, vacancy, management and capex sit outside the ratio.

Here is how the decision tends to sort out:

• Property held personally, modest rehab budget, equity above 30%: a 70% CLTV investment line may fit.
• Property held in an LLC: the equity line is off the table; a DSCR cash-out is the practical route.
• Large rehab with uncertain scope: a revolving line helps match draws to contractor invoices, but plan for the repayment shift.
• Equity thin after the first mortgage: neither product helps much. Consider phasing the work or reducing scope.

Key Terms Defined

CLTV: Combined loan-to-value, the total of all loans on the property divided by its value.

Draw period: The stretch when you can borrow from the line, usually with interest-only payments.

Repayment period: The phase after the draw ends, when principal and interest are both due.

Second lien: A loan that ranks behind the first mortgage if the property is sold or foreclosed.

DSCR: Debt service coverage ratio, a property’s rent divided by its full monthly housing payment.

Vesting: How title to the property is held, such as an individual, trust or LLC.
