The Quick Read: The best program for your situation is the one that matches the property’s use, your credit profile, and the equity you hold, because a home equity line only creates cash and the purchase loan still has to approve that cash.
- A home equity line of credit (HELOC) does not buy the second property. It produces cash that you put toward a down payment, closing costs, or reserves on a separate purchase loan.
- On the wholesale network Lendmire works with, a line secured by an investment property tops out at 70% combined loan-to-value (CLTV). A line on a second home or a primary residence reaches 90% CLTV only at a 720-or-better credit profile.
- Two lenders and two files are involved. The line lender checks your equity, credit, and debt. The purchase lender decides whether borrowed money counts.
- Open the line before you go under contract, and confirm the purchase lender’s rules on borrowed funds before you draw.
- A rental purchase usually runs on a DSCR loan, which looks at the property’s rent against its own payment. A personal second home runs on your income instead.
How a HELOC Fits Into a Second-Home Purchase
A HELOC is secured by a property you already own, usually your primary home. The home you are buying is financed only by the purchase loan. Those are two separate liens on two separate properties.
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.
Bankrate notes that not all lenders allow home equity funds to serve as a down payment when you are also taking a mortgage on the new property. That is the catch behind the whole topic. The line lender usually cares about its collateral, not what you spend the money on. The purchase lender cares a great deal about where your cash came from.
So the best setup is a pairing. The line lender permits the use, the purchase lender accepts the source, and the new property passes on its own numbers. No single product wins in the abstract.
Brokers see this from the middle. Across the wholesale network, the programs differ on leverage, credit floors, and property types. A broker that shops several lenders can match the file to the program. A single bank can only offer its own.
Step by Step: How Underwriting Treats the Two Files
Here is the sequence that usually works, from equity check to closing.
1. Check your equity. Equity is your home’s value minus what you owe on it. The line lender caps how much of that value you can borrow against, which is the CLTV limit.
2. Open the line before you shop. The line lender reviews your income, debts, and credit. Do this before you sign a purchase contract, not after.
3. Draw the cash into your own account. Parking the money in your personal account (or the account that will close the purchase) gives the purchase underwriter a clean trail.
4. Document the source. Expect the purchase lender to ask for the line’s statement and the bank statements that show the draw landing.
5. Run the purchase as its own file. The new loan is underwritten on its own terms. A rental purchase qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. A personal second home leans on your income and debts.
6. Plan the exit. The line is usually interest-only while you draw and then amortizes. You need a plan to pay it down.
One program rule shapes step 2. On the programs in this network, at least 75% of the line is drawn at closing. Size the line to the cash you actually need. An oversized line means interest-only payments on money that is just sitting there.
Another rule matters for the line itself. The line lender reviews your file on the interest-only payment calculated on the maximum draw. Debt-to-income (DTI) tops out at 50% on these programs, and a ratio above 45% requires a 680 credit minimum.
What the Network’s Equity Lines Look Like
The network places lines through two wholesale programs. The first is a higher-leverage program, with a 3-year interest-only draw and a 17-year fully amortizing repayment. The second is a longer-runway program, with a 5-year draw and a 25-year repayment. Pricing floats across both the draw and the repayment period and never converts to fixed. Investment lines run only the 5-year draw and 25-year repayment structure.
Here are the second-home leverage tiers, for lines up to $500,000. Each applies within program guidelines and subject to full file review.
| Credit profile | Max CLTV (second home) |
|---|---|
| 720+ | 90% |
| 700+ | 85% |
| 680+ | 85% |
| 660+ | 80% |
| 640+ | 75% |
Second-home lines start at a 640 minimum score and cap at $500,000. On an investment property, the ceiling is 70% CLTV with no tier above it, and the credit floor is 700. A primary-residence line can reach 90% CLTV at 720 or better.
Other parameters worth knowing:
- Line size. Lines run from $25,000 to $750,000. A line above $500,000 is primary-residence only. It requires a full appraisal and caps at 75% CLTV.
- Valuation. Lines at or below $500,000 usually run an automated valuation with no traditional appraisal. A higher CLTV may call for a second valuation, and you can request a full appraisal anyway.
- Property types. Single-family, 2-4 units, PUD, townhome, and condominium (including non-warrantable) are eligible. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural zoning are not offered.
- Title. The property must be held by you individually or in a revocable living trust. An LLC cannot hold title on the line. A property already deeded to an LLC needs a vesting change, or a DSCR cash-out refinance instead (subject to program terms).
- Exposure. A borrower can hold up to three lines, and more than 15 financed properties makes the borrower ineligible.
- Availability. Lines are available in 16 full-service states: AL, CA, CO, FL, GA, IN, MI, MT, NM, NC, OH, PA, TN, TX, VA, and WA. That is narrower than Lendmire’s 41-market DSCR footprint, which includes Washington, D.C.
Some states shorten the draw and repayment periods, and a few cap leverage by credit profile. A broker checks your state against each program before recommending one.
Personal Second Home vs. Rental: Two Different Lanes
These are different loans with different rules, and Bankrate points out that investment properties face stricter eligibility than second homes.
| Factor | Personal second home | Rental property |
|---|---|---|
| Purchase loan basis | Your income and debts | Property rent vs. its payment |
| Line ceiling (network) | Up to 90% CLTV at 720+ | 70% CLTV |
| Line credit floor | 640 | 700 |
| Does the line payment count? | Usually in your DTI | Generally outside the DSCR ratio |
Market surveys, such as the one at Bankrate, report that an investment property typically needs 15–25% down. On the DSCR purchase side of the network, most files land at 75%–80% loan-to-value (20%–25% down). Select programs reach 85% LTV (15% down) at about a 700+ score.
Rental files qualify on coverage. DSCR is the property’s monthly rent divided by its monthly payment of principal, interest, taxes, insurance, and any HOA dues. Many select programs start at 1.00 coverage. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Stronger ratios open better pricing and leverage.
Clearing 1.00 is not the same as positive cash flow. Repairs, vacancy, management, utilities, and capex all sit outside the ratio. Your line payment sits outside it too, but it still has to be paid from your real cash.
Our complete DSCR loans guide walks through how that ratio works.
Where the General Rule Breaks
“A HELOC works as a down payment” is true often, but not always. These are the edge cases that trip people up.
Borrowed funds are tested by pot. Down payment, closing costs, and reserves can each be treated differently. Some purchase lenders want a portion of your cash to come from seasoned savings. Others accept a fully borrowed down payment. Ask the purchase lender before you draw. After you draw, there is no taking it back.
A fully borrowed down payment stacks two debts on one rent stream. The property carries its own loan. Your equity carries the line. The rent only ever has to cover the first one in the DSCR math, yet you pay both.
Lien order can matter. The line sits on a different property than the new purchase, so the two do not compete directly. But a line on a property already carrying a first mortgage will sit in second position, behind that first loan. A rental you want to pull equity from later needs the same check.
Prepayment penalties can break the plan. Many DSCR loans carry a prepayment penalty step-down. A strategy of drawing the line, buying, and refinancing right away needs that checked first. Cash-out refinances on the network top out at about 75% LTV on a standard rental, and about 6 months of seasoning is the common expectation. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
Lines can freeze. The Consumer Financial Protection Bureau explains in its HELOC guide that a lender may stop further draws if your home’s value drops significantly or your finances change. Draw the money before you go under contract, not mid-deal.
The draw period ends. The same guide notes that monthly payments are often significantly higher once repayment begins, and in some cases the whole balance is due. If your hold plan is long, model that shift.
Selling the collateral home closes the line. If you sell the home that secures the line, you generally have to pay it off in full.
Your primary home takes the risk. Nasdaq points out that failing to repay a HELOC risks losing the primary residence to foreclosure. A rental that underperforms does not stop the lien on your home.
What Makes a Program the Right Fit
“Best” depends on five things. Ask about each one before you pick.
| Criterion | Why it matters | What to ask |
|---|---|---|
| Occupancy of collateral | Sets the CLTV ceiling | Is this primary, second home, or investment? |
| Credit profile | Sets the leverage tier | What score tier applies to my file? |
| Draw structure | Sets how long you pay interest only | 3-year or 5-year draw? |
| Title | LLCs cannot hold it | Is the collateral in my name or a trust? |
| Purchase-lender acceptance | Decides if the cash counts | How is borrowed money treated for down payment and reserves? |
The strongest files pass two tests: enough equity and enough rental coverage. A larger down payment lowers the purchase payment and can lift the coverage ratio. But it never erases leverage caps, credit floors, reserve rules, or property eligibility.
Reserves vary by lender, leverage, loan size, and transaction type. They commonly run around 6 months of the full monthly payment. Conservative rate-and-term files at modest leverage under $1,500,000 can see reserves waived. Larger loans typically step up to about 9 months. Loan sizes run up to $3,000,000 on standard programs (smaller balances available through select lenders), and above $2,500,000 the network generally holds to 30-year fixed structures.
A Worked Scenario
Run the numbers on an investor with a primary residence that carries solid equity and a 720-plus credit profile. She wants a duplex as a rental. She opens a line on her primary residence sized to cover the down payment and closing costs, not more. On a primary residence, the line’s ceiling can reach 90% CLTV at her credit tier, so the line itself is not the constraint.
The purchase runs as a DSCR loan at 75% LTV, meaning a 25% down payment. Assume the duplex’s rent clears roughly 1.2x coverage on the full monthly payment. That ratio is an assumption for this example, not a market figure. At that coverage, the file sits above the 1.00 level where many select programs start, which supports stronger pricing and leverage. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
Now the real-world check. Her line payment sits outside the DSCR ratio. It is still a real bill. Add the primary mortgage, the line, and the new loan, and she carries three obligations. If vacancy runs long or a roof fails, the rent may not cover all three. The ratio says the rental covers its own loan. It does not say the portfolio throws off cash.
Two other paths are worth comparing. A DSCR cash-out refinance can pull equity from a property already held in an LLC, where a line cannot work. And for investors who qualify on bank statements instead of a lease, Lendmire’s article Best Bank Statement HELOC Program to Purchase a Second Home covers that route.
When Not to Do This
A line is the wrong tool in several cases.
- You need the money for longer than the draw period, and you have no exit plan.
- The deal has no value-add or appreciation story. Without one, borrowed down payment money adds cost and risk but little else.
- Your DTI is already near the 50% ceiling.
- Your credit profile sits below the second-home floor of 640 or the investment floor of 700.
- The purchase lender does not accept borrowed funds. Confirm this first.
- The property you want is a manufactured home, log home, or barndominium. Those fall outside the network’s programs.
Key Terms Defined
HELOC (home equity line of credit): An open-end credit line secured by a property you own, which you can draw from repeatedly up to a limit.
CLTV (combined loan-to-value): All loans secured by a property, added together, divided by its value.
Draw period: The stretch when you can borrow from the line, usually paying interest only.
Repayment period: The stretch after the draw ends, when you can no longer borrow and the balance amortizes.
DSCR (debt service coverage ratio): A rental’s monthly rent divided by its monthly payment of principal, interest, taxes, insurance, and HOA dues.
DTI (debt-to-income ratio): Your monthly debt payments divided by your monthly income.
Seasoning: The waiting period a lender wants between two events, such as buying a property and refinancing it.
Frequently Asked Questions
What is the best HELOC program to buy a second home?
It depends on whether the home is personal or a rental, on your credit profile, and on how much equity you hold. On this network, a line secured by a second home tops out at 90% CLTV, and only at a 720-or-better credit profile. A line secured by an investment property caps at 70% CLTV. A broker compares programs against your file instead of naming one winner.
Can I use a HELOC for the entire purchase price?
Sometimes, but usually not through a purchase loan that also finances the home. Some purchase lenders cap the borrowed share of your cash. Lines also cap at $750,000 on this network, and above $500,000 the line is primary-residence only. Most buyers use the line for the down payment and closing costs.
Does the HELOC payment hurt my DSCR?
Generally no. DSCR programs compare the rental’s rent to the rental’s own payment, so the line payment usually sits outside the ratio. It still hits your real cash flow, and it counts in DTI-based qualification on a personal second home.
Can I get a HELOC on a property held in an LLC?
No. On this network, LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title on the line. You need individual title or a revocable living trust. A DSCR cash-out refinance can work for an LLC-held property, subject to program terms.
Is a HELOC good for a vacation home I will also rent?
It can be, but the lender decides how to classify the property. A home you rent out is generally treated as an investment property, which carries a 70% CLTV ceiling on the line and stricter eligibility. Short-term rental rules can vary by city, county, HOA, and property type, so investors should confirm local rules before relying on projected rental income.
