The Quick Read: A home equity line (HELOC) can supply cash for both a business purchase and a second-home down payment, but it only produces money, so each deal’s lender decides separately whether borrowed funds count, and you carry the line’s payment on top of every other obligation.
- The line comes first. You borrow against equity in a home you already own. The purchase lender then reviews that cash on its own terms.
- Leverage depends on occupancy. Across Lendmire’s wholesale network, a line on a primary residence or second home reaches 90% combined loan-to-value (CLTV) only at a credit profile of 720 or better. On an investment property, the ceiling is 70% CLTV. CLTV is your total mortgage debt as a percent of the home’s value.
- Most of the line is drawn at closing. Plan it as a lump sum, not a revolving pool you tap whenever you like.
- Acquisition lenders want your own equity. Borrowed money can count in some structures, but it needs a repayment source outside the business you are buying.
- The line’s payment sits outside the rental-coverage math. A property can clear its own test and still strain your cash after the line is paid.
How a HELOC Works for These Two Goals
A HELOC is a line of credit secured by your home. You borrow against equity, which is the home’s value minus what you owe on it. The line has a draw period, when you can borrow, and a repayment period, when you pay it down.
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.
Lendmire is a broker, not a lender. It places these lines through select wholesale partners, and every figure below is subject to lender guidelines and full file review.
Two uses, two different problems. For a second-home down payment, the line is only a cash source. A separate purchase loan buys the property, and that lender decides how to treat the borrowed cash. For a business purchase, the cash feeds an acquisition where the buyer’s lender, or the seller, sets the rules for borrowed equity.
Most files in this network use a standalone line sitting in first or second lien position. Behind a first mortgage, it is a second lien. Your first mortgage stays untouched.
Here is the part that surprises people. On both draw structures in this network, at least 75% of the line is drawn at closing. Pricing floats during the draw and the repayment period and never converts to fixed. So you start paying interest on most of the line on day one, whether or not the money has a job yet.
What Can You Borrow? Sizing the Equity
The formula is simple. Take the home’s value, apply the CLTV ceiling for your credit profile and occupancy, then subtract what you owe on the first mortgage. That is the maximum. The lender’s own valuation and your debt load can cut it lower.
The ceiling changes with the property that secures the line:
| Line secured by | CLTV ceiling | Credit floor | Draw structures |
|---|---|---|---|
| Primary residence | Up to 90% at 720+ | 600 program floor | Either one |
| Second home | Up to 90% at 720+ | 640 | Either one |
| Investment property | 70% | 700 | 5-year draw only |
The two draw structures are a 3-year interest-only draw followed by a 17-year amortizing repayment, and a 5-year interest-only draw followed by a 25-year amortizing repayment. The 5-year version is the longer-runway structure. Investment lines use it only.
On a second home, the ceiling steps down with credit: 90% CLTV at 720 or better, 85% from 680, 80% from 660, and 75% from 640, all on lines up to $500,000. Some states apply their own caps or waiting rules, so the property’s location matters.
Other limits that shape the plan:
- Line size: $25,000 to $750,000.
- Large lines: a line above $500,000 is for primary residences only. It needs a credit profile of 700 or better (720 on the longer-runway structure), caps at 75% CLTV, and requires a full appraisal.
- Valuation: lines at or below $500,000 ordinarily use automated valuation. A higher CLTV may call for a second look.
- Debt-to-income: 50% maximum, and 45% for credit profiles from 600 to 679. The lender reviews your file on the interest-only payment calculated as if you drew the maximum.
- Credit report: no more than 90 days old at closing, with no rescores.
That DTI detail matters here. The lender counts the full line as if drawn, even if you plan to use half.
The network offers these lines only in Lendmire’s 16 full-service states, which is narrower than the 41-market DSCR footprint. Title must sit with you personally or in a revocable living trust. An LLC cannot hold title on a HELOC. That is the sharpest structural difference from a DSCR loan.
Step by Step: HELOC Cash to a Second-Home Down Payment
Start with the use of the second property. A second home you use personally and a rental you buy to lease out are underwritten very differently. The first usually runs through a conventional, income-based loan. The second can run through a DSCR loan, which is an investor loan that looks mainly at whether the property’s rent covers its own payment. Lendmire’s complete DSCR loans guide covers that product in depth.
Then the sequence runs like this:
1. Close the line first. The line is underwritten on the equity in the home that secures it. It is not underwritten on the property you plan to buy.
2. Draw and park the cash. Because most of the line is drawn at closing, the money lands in your own account. Keep it there, in your name, with a clean paper trail.
3. Let the purchase lender review the source of funds. Down payment, closing costs, and reserves are three separate tests. A program can accept borrowed money for one and reject it for another. Some lenders also want borrowed funds to sit in your account for a period first. This is called seasoning.
4. Watch how the payment is counted. On an income-based loan, the line’s payment joins your personal debts and raises your debt-to-income ratio. On a DSCR loan, the ratio looks at rent versus the new property’s payment. The line is not in the ratio.
5. Count three payments. You now carry the first mortgage, the line, and the new property loan.
Step 4 is where investors fool themselves. A DSCR test compares rent to the property’s own payment and nothing else. Repairs, vacancy, management, and the line’s payment all sit outside it. A deal can clear the lender’s test and still leave you short.
Step by Step: HELOC Cash to a Business Purchase
Buying a business is a different animal. No single rule governs it. The answer depends on who finances the deal and what that lender allows.
The most structured case is a bank loan backed by the Small Business Administration’s 7(a) program. For a complete change of ownership, SBA’s operating rules call for a minimum 10% equity injection of total project costs. That is your own money going in.
Borrowed money can count, but not freely. Lenders must show an outside source of repayment for borrowed injection funds. In practice, that means income from somewhere other than the business you are buying. The salary that business pays you is the same cash flow, so it is a weak answer.
Two documentation points:
- Paper trail. Lenders keep copies of checks or wires, account statements showing available funds (at least 30 days), and settlement statements.
- Seller notes. Per Whiteford’s client alert, a seller note counts toward the injection only if it sits on full standby for the whole loan term. It also cannot exceed 50% of the injection.
For a non-SBA deal, such as seller financing or a bank term loan, each lender sets its own treatment of borrowed equity. Ask before you draw. If the lender refuses borrowed funds, you have already borrowed against your home.
One more thing. Buying a business changes your income picture. If you are mid-application on a line or a mortgage, tell your broker early. A shift from salaried to self-employed income can change which program fits.
Doing Both: One Pool of Equity, Two Goals
Splitting one line across two purchases is the gap most investors stumble into. Here are the moving parts.
Sequence matters. Close the line before you apply for the purchase loan. The line’s payment shows up in debt calculations, and you want the second-home lender to see the final picture once, not twice. Do the same for the business lender. Each new obligation changes the math on the other.
Keep the money separate. Put the down payment funds in one account and the acquisition funds in another. Clean records help both lenders trace the source of funds.
Stress-test the stack. Run these scenarios before you commit:
- The business earns less than projected for several months.
- The line’s payment moves because pricing floats.
- The interest-only draw ends and amortization starts, which changes the payment’s shape.
- The rental sits vacant for a stretch.
Picture an owner with a 740 score, a primary residence with substantial equity, and a rental they want to buy. The line’s ceiling on a primary residence reaches 90% CLTV at that score. The rental’s rent might clear its own payment at roughly 1.2x. But the line’s payment, the first mortgage, and any business draw all come out of the same household income. Clearing 1.2x says nothing about that.
The business purchase adds a risk the rental doesn’t: your home becomes collateral for a venture that could fail. A rental at least produces rent from day one.
Where the General Rule Breaks
The general rule is that a HELOC can fund a down payment if the purchase lender accepts it. Here are the exceptions.
- Borrowed share caps. Some programs accept a line draw for the down payment but cap the borrowed share. Others want some seasoned personal cash in the deal.
- Reserves are separate. Many lenders exclude borrowed funds from reserves. A HELOC may cover the down payment but not the cushion behind it.
- A fully borrowed down payment. If the line pays the whole down payment, you start with little or no real equity in the property. Not ideal.
- The line can shrink. The CFPB’s HELOC booklet says a lender may freeze or reduce a line if the home’s value falls. That is a bad time to count on a draw.
- Payoff at sale. The same booklet says that if you sell the home, you generally must pay the line off in full right away.
- Renting your own home. The booklet also notes that line terms may prohibit renting the secured home to others.
- Default risk. The CFPB’s overview of HELOCs warns that falling behind could cost you the home. It describes the line as an open-end credit, with repayment periods often running ten or 20 years.
- Exposure caps. A borrower is limited to three lines. Combined exposure caps at $2,000,000 on one structure and $750,000 on the other. Owning more than 15 financed properties makes you ineligible.
- Title. A property already deeded to an LLC needs a vesting change first, or a DSCR cash-out instead.
- Listed properties. In several states, a property listed for sale, or listed in the past 60 days, is ineligible.
- Property types. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not eligible for these lines. DSCR loans do not cover manufactured homes, log homes, or barndominiums either.
Credit history is its own gate. Bankruptcy needs 4 years of seasoning from discharge or dismissal. On primary residences and second homes, one program seasons a foreclosure at 7 years, and a deed-in-lieu, pre-foreclosure, or short sale at 4. The other program declines the history regardless of age.
HELOC or Something Else?
A HELOC isn’t the only way to pull equity. Here is how the main options compare.
| Option | What secures it | Best fit |
|---|---|---|
| HELOC on your home | Your home, second lien | Keep the first mortgage as is |
| HELOC on a rental | The rental property | Rental holds equity; 70% CLTV cap |
| DSCR cash-out refinance | The rental property | Seasoned rental; replaces the first mortgage |
| Savings or sale proceeds | Nothing | You want no new debt |
On a standard rental, a DSCR cash-out refinance tops out around 75% LTV across most of the network. Expect about 6 months of seasoning as the common benchmark. That path replaces the rental’s first mortgage, which a HELOC does not. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.

A Go or No-Go Checklist
Before you draw a dollar, check these:
- Does the purchase lender accept borrowed funds? Ask in writing for the down payment, closing costs, and reserves separately.
- Can your household income carry the line’s payment? Assume the full line is drawn, since that is how lenders qualify it.
- Is there an outside repayment source for the business? If the only income paying the line is the business’s own cash flow, the plan is weak.
- Do you have reserves that don’t come from the line?
- Is there an exit? A cash-out refinance, a sale, or a clear paydown schedule.
Fund neither if you can’t answer the reserves and exit questions. Fund only the second home if the rental clears coverage with room to spare. Fund both only if household income holds under your stress test.

Frequently Asked Questions
Can one HELOC fund both a business purchase and a second-home down payment?
Often yes, but each lender reviews its half separately. The second-home lender looks at source of funds and your debt load. The business lender sets its own rules for borrowed equity. Because most of the line is drawn at closing, you split a lump sum, not a flexible pool.
Does a HELOC count toward reserves?
Often not. Many lenders accept borrowed funds for the down payment but want reserves from your own assets. Rules vary by program, so confirm before you rely on the line for both.
What is the maximum CLTV on a HELOC through Lendmire’s network?
It depends on occupancy. On a primary residence or second home, the ceiling reaches 90% CLTV, and only at a 720 credit profile or better. All figures are subject to lender guidelines.
Can I use a HELOC on a rental to buy another rental?
Yes, the line can sit on an investment property, with a 70% CLTV ceiling, a 700 minimum credit profile, and the 5-year draw structure only. The new purchase still needs its own approval. Its coverage ratio is judged on the new property’s rent versus its own payment.
Does the line’s payment affect my DSCR?
The ratio itself looks at the rental’s rent versus its payment, so the line is not in it. But the rent still has to cover the line in real life. A deal can clear the test and still lose money after both payments.
