5 HELOC Options to Put Equity to Work Buying an Investment Property

The Quick Read: Five routes exist for turning home equity into cash for a rental purchase: a line on your primary residence, a line on an existing rental, a line on a second home, a line used as a bridge before a refinance, and a non-line alternative such as a cash-out refinance. Each one changes whose equity is at risk, how much combined leverage is allowed, and what the new rental has to carry.

• A HELOC is a source of cash, not a purchase loan. You still need a first mortgage, often a DSCR loan, that is reviewed on its own.
• On Lendmire’s wholesale network, an investment-property line caps at 70% combined loan-to-value (CLTV) and $500,000, with a 700 minimum credit score.
• Primary-residence and second-home lines can reach 90% CLTV, but only at a 720-or-better credit profile.
• Most DSCR purchase files land at 75%-80% loan-to-value (LTV), so the down payment is the gap the line has to fill.
• The strongest files clear two tests: enough equity for the line and enough rental coverage for the new loan.

How a HELOC Actually Funds a Rental Purchase

A home equity line of credit (HELOC) is a revolving second loan secured by a property you already own. You borrow against the equity, meaning the gap between the property’s value and what you owe. The line is underwritten on you and the collateral. It is not underwritten on the rental you plan to buy.

That split matters. The purchase itself needs its own financing. A DSCR loan, which is a loan where the property’s rent rather than your personal income drives approval, is the usual choice. Across the programs Lendmire places files with, most purchases run at 75%-80% LTV, which means a 20%-25% down payment. Select programs reach 85% LTV (15% down) with roughly a 700+ score. Closing costs and reserves come on top. Reserves are liquid cash the lender wants you to hold after closing, commonly around 6 months of the property’s full payment (principal, interest, taxes, insurance), though the number moves with lender, leverage, and loan size.

Here is where a HELOC enters. It supplies the down payment, the closing costs, the reserves, or all three. DSCR lenders look at the rental’s income against the new loan’s payment. They do not replace that test with your equity.

Coverage works like this. DSCR is monthly rent divided by the full monthly housing payment. A 1.00 ratio 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. Clearing 1.00 is not the same as positive cash flow. Repairs, vacancy, management, utilities, and capital expenses all sit outside the ratio.

Lenders review where down-payment money comes from, and borrowed funds are a question to raise up front rather than at the last minute. How a particular lender treats a line-funded down payment varies, so ask before you draw.

The Five Options at a Glance

Ceilings are tied to occupancy on this network. An investment line never goes above 70% CLTV. The 90% figure belongs to primary residences and second homes, and only with a 720-or-better profile. Lower credit tiers carry lower ceilings.

Option 1: A Line on Your Primary Residence

A line on your primary residence is also the easiest option to qualify for, because lenders treat owner-occupied collateral as the safest. Lendmire’s network offers it as a standalone line in first or second lien position, in sizes from $25,000 to $750,000. Only a primary residence can carry a line above $500,000. That larger size needs a 700 credit profile or better (720 on the longer-runway program, the one built on a 5-year draw and 25-year repayment). Lines of that size cap at 75% CLTV and require a full appraisal.

Two draw structures exist on primary residences. One runs a 3-year interest-only draw followed by a 17-year repayment. The other runs a 5-year draw followed by a 25-year repayment. Pricing floats through both the draw and repayment periods and never converts to fixed.

The tradeoff is plain: your home secures the money that buys the rental. If the rental underperforms, the lien is still on your house. The test is whether you are willing to risk your primary residence for the purchase, and whether the new property can carry its own mortgage plus the line.

Qualification here leans on you, not the rental. The network looks at a 50% maximum debt-to-income ratio (45% for credit profiles from 600 to 679), calculated on the interest-only payment at the maximum draw.

Option 2: A Line on an Existing Rental

You can borrow against a property you already rent out. NerdWallet’s guide to HELOCs on investment properties notes that not all lenders offer them, that requirements are strict, and that multiple appraisals may be required. Lendmire’s network does offer them, within tight limits.

• Leverage: 70% CLTV maximum, with the first mortgage counted in that figure.
• Credit: a 700 minimum. Credit above 700 does not buy more leverage, because 720 and 700 both top out at 70%.
• Size: the maximum line is $500,000.
• Structure: the 5-year draw and 25-year repayment structure only.
• Valuation: because the line caps at $500,000, it normally runs through an automated valuation and commonly closes with no traditional appraisal. A borrower can still request a full appraisal.

Market surveys, including the NerdWallet guide above, report that lenders commonly look for about 20% equity and a 720 score on investment-property lines. On this network the investment-line numbers are the 70% CLTV ceiling and the 700 floor.

Title is where many investors get caught. The borrower must hold title as an individual or in a revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. That is the sharpest difference from a DSCR loan, where an LLC is common, subject to program terms. A rental already deeded to an LLC needs a vesting change first, or it is better served by a DSCR cash-out.

Option 3: A Line on a Second Home

A second home is its own occupancy category in lender matrices, and the terms sit between primary and investment. On this network the credit floor is 640, and the ceiling reaches 90% CLTV only at a 720-or-better credit profile. The same draw structures apply as on a primary residence.

If you own a vacation property with real equity, this can be the strongest source of cash you have. Eligibility is narrower than it sounds. Single-family homes, 2-4 units, PUDs, townhomes, and condos (including non-warrantable condos) can qualify. Manufactured homes, co-ops, condotels, log homes, and commercial, mixed-use, or agricultural-zoned properties are not offered.

Option 4: A Line as a Bridge Before a Refinance

Some investors treat the line as short-term money. They draw it, buy and renovate a property, then refinance the new property to pay the line off. This is the BRRRR approach (buy, rehab, rent, refinance, repeat). It is a use of the line, not a different type of line. The collateral still comes from options 1 through 3.

Consider a structural fact about this network’s lines: at least 75% of the line is drawn at closing. A bridge plan therefore does not leave you holding an undrawn reserve, and you pay interest on most of the line from the first day.

The plan works only if the refinance appraises high enough to retire the line. A DSCR cash-out refinance tops out around 75% LTV across most of the network, and about 6 months of seasoning is the common expectation before one. Short-term rental collateral runs lower, at 70% on a cash-out. If renovations underdeliver on value, you can be left holding both loans.

Check the prepayment terms on the first mortgage before you plan a quick refinance. A DSCR loan paid off early can carry a prepayment penalty depending on the program, and those schedules vary.

Option 5: When a HELOC Is the Wrong Tool

Sometimes the better move is not a line at all. Three alternatives come up most often.

• A home equity loan delivers a lump sum, usually at a fixed rate, rather than a revolving line.
• A cash-out refinance on your home replaces the existing mortgage with a larger one, so the whole balance is repriced, not just the new money. A HELOC typically adds a second lien and affects only what you draw.
• A DSCR cash-out refinance on an existing rental pulls equity from a rental based on its income, with leverage around 75% LTV on a standard rental across most of the network. It suits investors whose rentals are held in an LLC, or whose personal debt-to-income ratio is too high for a line. Lendmire’s DSCR cash-out refinance guide covers it in detail.

If you hold a low-cost first mortgage you would rather not replace, a line keeps it in place. If the first mortgage is expensive or the rental is in an LLC, the cash-out routes often make more sense. Sizing matters too. An investment line stops at $500,000, while a DSCR loan generally reaches up to $3,000,000 on standard programs, with smaller balances available through select lenders.

Does the Deal Still Work With the Line Payment?

Picture an investor who draws on a primary-residence line to cover the 25% down payment on a rental purchased at 75% LTV. The DSCR lender tests rent against the new first mortgage payment and finds coverage around 1.2x. That clears the lender’s test. It says nothing about the line. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.

The investor’s own math has to add the line’s payment. A standard DSCR calculation looks at the new loan’s payment, so the line sits outside the ratio. The cushion in a 1.2x file can shrink fast once a second payment on the borrowed down payment is added. Run it with vacancy and repairs as well. If the result sits near break-even, you are subsidizing the rental out of your paycheck.

The payment can also change. The CFPB’s consumer booklet on HELOCs explains the draw and repayment structure. It also notes that variable-rate plans can change your monthly payment, and that payments are often higher once repayment starts. Dwelling-secured variable-rate plans must carry a ceiling on how high the rate can go. On Lendmire’s network the draw period is interest-only, so the move into amortizing repayment is the moment payments step up.

One more point on leverage. If the line funds the down payment, you have borrowed against your home to put the full purchase price on debt. The first mortgage covers most of the price and the line covers the rest, so you hold little or no equity in the new property on day one. Appreciation, rent growth, and principal paydown have to build the equity the line used up.

Where the Rules Break

The general rule, that equity plus rental coverage gets you a deal, has several named exceptions.

• LLC-owned rentals. A line needs individual or revocable-trust title. An LLC cannot hold it, so a rental in an LLC needs a vesting change or a DSCR cash-out instead.
• Listed properties. In some states, a property that is listed for sale, or was listed within the past 60 days, is ineligible.
• Portfolio size. 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.
• Credit history. A bankruptcy needs 4 years of seasoning from discharge or dismissal. For foreclosures, one program seasons them at 7 years, and a deed-in-lieu, pre-foreclosure, or short sale at 4. The other program declines foreclosure-family history entirely.
• Property type. Manufactured homes, co-ops, condotels, log homes, and commercial, mixed-use, or agricultural-zoned properties are not offered on either program. The same goes for DSCR financing on manufactured homes, log homes, and barndominiums.
• Availability. Lendmire arranges these lines in 16 full-service states, which is narrower than its 41-market DSCR footprint, Washington, D.C. included. Confirm availability before you plan around one.
• Short-term rentals. If the new purchase is a short-term rental, DSCR purchase leverage tops out at 75% LTV, and lenders expect about 12 months of hosting history. Short-term rental rules vary by city, county, HOA, and property type, so investors should confirm local rules before relying on projected rental income. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.

Which Option Fits Which Investor?

A first-time buyer with a home and 720+ credit usually starts with option 1, because the leverage ceiling is highest. An investor who already owns several rentals and holds them in individual names may prefer option 2, though the 70% cap makes it the tightest. Someone with a vacation home and sizeable equity can look at option 3. A renovation-focused investor looks at option 4, accepting the refinance risk. Investors whose rentals sit in an LLC, or whose debt-to-income is too high, should price option 5.

Key Terms Defined

CLTV (combined loan-to-value): the total of all loans on a property, first mortgage plus line, divided by its value.

Draw period: the stretch when you can borrow from the line and typically pay interest only.

Repayment period: the later stretch when you can no longer draw and must pay down principal and interest.

DSCR (debt service coverage ratio): monthly rent divided by the full monthly payment on the property, used to judge whether a rental carries its own loan.

Seasoning: the waiting period a lender wants between two events, such as buying a property and refinancing it.

Reserves: liquid cash a lender wants you to hold after closing, usually counted in months of the property’s payment.
