Investment Property HELOC Requirements or Home Equity Loan on a Primary Home

The Quick Read: Investors can tap equity for a rental two ways: a line on the rental itself, which on Lendmire’s wholesale network needs a 700 credit score and caps at 70% CLTV and $500,000 on an investment property, or a line on a primary home, which reaches 90% CLTV only at a 720 score or better. The right route depends on which property you are willing to put at risk and who holds title. Both routes are subject to lender guidelines and full file review.

• A line on an investment property is a narrow product: 700 credit minimum, 70% CLTV, $25,000 to $500,000.
• A line on a primary home allows more leverage, but your residence becomes the collateral.
• Title must sit with an individual or a revocable living trust. An LLC cannot hold it.
• Your personal debt-to-income ratio drives approval, not the rent the rental earns.
• When an LLC, thin documentation, or portfolio size is the obstacle, a DSCR cash-out is usually the better fit.

What Are the Two Routes, Side by Side?

The two routes differ in collateral, leverage, and the person who bears the risk. Route A borrows against your primary home. Route B borrows against the rental. Each is underwritten on you as a borrower, so neither works like a DSCR loan.

Across the wholesale network, the equity-line programs are standalone lines. They sit in first or second lien position. A fixed-rate home equity loan is a lump-sum product, and the lines described here float and never convert to fixed. If you want a fixed lump sum, that is a different product with different guidelines.

Key Terms Defined

HELOC: A revolving line of credit secured by property equity, with a draw period followed by repayment.

Home equity loan: A lump-sum loan secured by equity, usually repaid on a fixed schedule.

CLTV: Combined loan-to-value, meaning all liens on the property added together and divided by its value.

DTI: Debt-to-income ratio, which compares your monthly debts to your monthly income.

DSCR: Debt service coverage ratio, which compares a rental’s rent to its own payment on principal, interest, taxes, insurance, and any HOA dues.

Draw period: The stretch when you can borrow from the line, paying interest only.

What Does a Line on the Investment Property Require?

A line secured by the rental is the strictest version of the product. On the network, an investment-property line requires a 700 credit score, with no tier below it. It caps at 70% CLTV, and the maximum line is $500,000. The minimum line is $25,000. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.

Notice the credit requirement has only one floor. A 720 score and a 700 score both reach 70% CLTV. Higher credit buys eligibility rather than extra leverage. Anything above 700 does not raise the ceiling.

Here is how the rest of the file looks:

• Structure: Investment lines use a 5-year interest-only draw followed by a 25-year fully amortizing repayment. No other structure exists on investment collateral.
• Draw at closing: At least 75% of the line is drawn at closing. You start paying interest on most of it right away.
• Payment behavior: Pricing floats through both the draw and the repayment period. It does not convert to fixed.
• DTI: The maximum is 50%. Qualification uses the interest-only payment calculated on the maximum draw, not on what you actually borrow.
• Valuation: Because the line caps at $500,000, it usually runs an automated valuation with no traditional appraisal. A borrower can still request a full appraisal.
• Property types: Single-family, 2-4 units, PUDs, townhomes, and condominiums, including non-warrantable ones, are eligible. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not eligible.

Reserves and income documentation depend on the lender and the file. Business bank-statement analysis needs a 680 minimum, but investment lines already floor at 700, so that is never the binding constraint.

How Does Borrowing Against a Primary Home Change the Math?

A primary-home line allows more leverage because the lender is financing an owner-occupied residence. The ceiling reaches 90% CLTV on a primary residence, but only at a 720 score or better. At lower scores the ceiling steps down. Do not assume the top tier applies to you.

Two draw structures exist on primary residences and second homes. One is a 3-year interest-only draw with a 17-year repayment. The other is a 5-year draw with a 25-year repayment. The network has two wholesale programs behind these structures. One is built for higher leverage. The other is built around the longer interest-only period. Each figure below applies only within its own program’s terms.

Line size runs from $25,000 to $750,000. A line above $500,000 is primary-residence only. It needs a credit profile of 700 or better (720 on the longer-runway program), caps at 75% CLTV on a primary residence, and requires a full appraisal.

Credit is read on a single-bureau score model keyed to the primary wage earner. The report can be no more than 90 days old at closing. Rescores are not available. The program floor is 600, and the DTI ceiling is 50%. Profiles from 600 to 679 are held to 45%, and any ratio above 45% requires a 680 minimum.

A borrower is limited to three lines. Combined exposure caps at $2,000,000 on the higher-leverage program and $750,000 on the longer-runway program. A borrower with more than 15 financed properties is not eligible.

Home Equity Loan vs. HELOC: Which Fits a Rental Purchase?

A line fits when your timing is uncertain. A lump sum fits when you know the exact amount you need. For a rental down payment, the amount is usually known, so a lump sum matches the need more neatly.

The line’s structure works against that. With at least 75% of the line drawn at closing, you are borrowing most of it whether or not you need it. If you size the line to the down payment, the draw-at-closing rule is fine. If you size it for flexibility, you pay interest on unused cushion.

A federal consumer booklet on these products notes that lines carry a fixed draw period, may be renewed, and sometimes end in a balloon payment. The network’s lines fully amortize after the draw period, so a balloon does not apply here. The same booklet warns that a borrower who sells the home will probably have to pay the line off in full. Plan for that if a move is on the horizon.

Where Do the General Rules Break?

The general rule is that equity can fund a rental. The exceptions decide whether your particular file works. These are the ones that come up most.

Title and vesting. The line requires fee simple or leasehold title held by an individual or an inter vivos revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. This is the sharpest difference from a DSCR loan. A property already deeded to an LLC needs a vesting change first, or a DSCR cash-out instead.

Undrawn lines as reserves. An undrawn line generally does not count as reserves on a DSCR file. Reserves usually need to be verified cash or liquid assets, commonly around 6 months of PITIA. Requirements vary by lender, leverage, loan size, and transaction type.

The line payment and the DSCR ratio. The line’s payment does not change the DSCR on the rental. The ratio compares the rental’s rent to the rental’s own payment. The line payment lands in your personal DTI instead.

A line can be frozen. A lender may block further draws if the home’s value falls significantly or your finances change, according to the CFPB’s HELOC explainer. This matters if your plan depends on a draw you have not taken. Draw what the deal needs at the start.

Borrowing the whole purchase. Funding a purchase entirely with a line means borrowing roughly the full value of the property. One investor discussion on using a line for a down payment or a full purchase raises the sharpest question: are you willing to risk your primary residence for a rental? The question is fair, and it has no universal answer.

Mixed-use draws. If part of a draw funds the rental and part funds personal spending, keep the records clean.

Ineligible properties. Manufactured homes, co-ops, condotels, log homes, commercial, and mixed-use properties are not offered on these lines. A listing-status rule also applies. In several states, a property listed for sale, or listed within the past 60 days, is ineligible.

Availability. Lendmire arranges these lines only in its 16 full-service states. That is narrower than its 41-market DSCR footprint, which includes Washington, D.C.

What Does a Real Decision Look Like?

Run the numbers on a purchase financed with a DSCR loan, where the down payment comes from a line on your primary home. Assume 25% down on a standard purchase. Most files land at 75% to 80% LTV on an investment purchase, so that is a normal structure.

Say your primary home has a 740 score behind it. That supports a CLTV ceiling up to 90% on a primary residence, so the equity needed for a 25% down payment may be well within reach. The line is underwritten on your DTI, using the interest-only payment on the maximum draw.

Then the DSCR file is reviewed on its own terms. The rent has to cover the rental’s own payment at the program’s coverage floor. Say rents clear roughly 1.2x. That is solid coverage on a standard purchase.

Clearing 1.0 is not the same as positive cash flow, though. The ratio compares rent to PITIA only. Repairs, vacancy, management, utilities, and capex sit outside it. You also carry the line payment from your own income, and it floats. A purchase that covers its own loan at 1.2x can still strain you if the line payment rises and the rental sits vacant.

This is the flip point. If your rental clears the coverage test with room to spare, and your personal income comfortably supports the line payment, Route A works. If either side is thin, you are stacking two thin margins, so reconsider.

When Does a DSCR Cash-Out Beat Both Routes?

A DSCR cash-out beats both lines when the obstacle is title, income documentation, or portfolio size. It keeps the debt on the rental, so your residence is not the collateral. Tapping equity from an existing rental to buy the next one avoids the home-risk question entirely.

Here is how the pieces fit on the network:

• Cash-out leverage: Tops out around 75% LTV on a standard rental, with about 6 months of seasoning as the common expectation.
• Coverage: 1.00 is where many select programs start. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Stronger ratios open better pricing and leverage.
• Credit: A 620 floor exists in parts of the network, most programs want around 660, and 700+ unlocks the strongest leverage tiers.
• Loan size: up to $3,000,000 on standard programs (smaller balances available through select lenders). Above $2,500,000, the network generally holds to 30-year fixed structures.
• Structure: The spine is the 30-year fixed. Extended terms, interest-only periods, and ARM structures are available through select lenders.
• Short-term rentals: Cash-out runs around 70% LTV on short-term-rental collateral, versus 75% on a standard rental. Expect a 640+ score and about 12 months of hosting history.
• Not offered: DSCR on manufactured homes, log homes, and barndominiums.

Line programs and DSCR loans also differ in who can hold title. DSCR loans commonly close in an entity name, subject to lender program eligibility. That alone moves many portfolio investors off the line route. For the full picture, see the complete DSCR loans guide.

A larger down payment lowers the monthly payment and can lift the DSCR. It never erases leverage caps, credit floors, reserve rules, or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage.

How Should You Choose?

Choose by which risk you can live with. A line on your residence offers the most leverage and puts the most at stake. A line on the rental protects the home but caps at 70% CLTV on an investment property. A DSCR cash-out moves the underwriting to the property itself.

Route A tends to suit an investor with strong personal income, a 720+ score, one rental, and a short repayment plan. An investor discussing using a line from a primary home for a first investment property argues that this fits a short hold with a repayment plan, not permanent down-payment financing. Treat that as one investor’s opinion rather than a rule.

Route B suits an investor who already owns the rental, holds title personally, and wants to keep the residence clear. The 700 credit floor and the $500,000 cap are the constraints to check first.

A DSCR cash-out suits an investor with an LLC, multiple rentals, or income that is hard to document. The tradeoff is that the property has to clear the coverage test.
