The Quick Read: A bank will lend you a home equity line to buy another house when the line sits on a home you live in, your credit and debt load fit its rules, and the purchase lender accepts borrowed funds, so the right match depends on your property, your equity, and your leverage. Lendmire is a mortgage broker, not a lender. It places these lines through a network of wholesale lenders, subject to lender guidelines and full file review.
- Many banks limit these lines to a primary residence, so the home securing the line matters as much as the bank.
- Your equity does not set the line size. The lender’s combined loan-to-value cap does.
- A home equity line is underwritten on you: your income, credit, and debts. A DSCR loan is underwritten on the new property.
- The purchase lender decides whether borrowed money counts toward the down payment, closing costs, or reserves.
- The line is secured by the home you live in, so a missed payment puts that home at risk.
Which Banks Offer a HELOC to Buy Another House?
Banks do not publish a list of who allows it, and the answer changes by lender type, occupancy, and loan purpose. Lender policies, not a brand name, decide it. Large retail lenders, regional banks, credit unions, online lenders, and brokers each treat this use differently.
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.
The most common pattern is simple. Banks tend to write lines on a home the borrower lives in. A BiggerPockets Rookie Reply says many banks do not give lines on rental properties at all. Its hosts add that a commercial line from a small local bank is the usual alternative for rentals.
Use this table as a starting map, not a verdict. Each cell describes a tendency, and any single lender can differ.
| Lender type | Typical tendency | Ask them |
|---|---|---|
| Large retail bank | Primary-residence lines; strict purpose terms | Any limits on using funds for another property? |
| Regional bank | Mixed; some flexibility on file structure | Do you allow second homes or rentals as collateral? |
| Credit union | Often member-based, primary homes | Does the line stay open if I move out? |
| Online lender | Standardized rules, set property types | What property types and vesting do you accept? |
| Broker with wholesale lenders | Compares several programs on one file | Which program fits my equity and credit? |
The best program for your situation depends on the occupancy of the home, your credit profile, how much leverage you need, and your debts.
How Underwriting Treats It, Step by Step
The lender runs your equity line as a personal-credit loan. It checks the home, then you, then the purchase plan. Six steps cover what actually happens.
Step 1: The equity test. The lender caps your combined loan balance at a percentage of the home’s value. That cap is called combined loan-to-value, or CLTV. A BiggerPockets moderator makes the point that having a pile of equity does not mean you get a line of that size, because the lender’s cap decides it.
Here is the math in percentages. Say your home is worth 100 units and your mortgage balance is 45 units. A tier at 75% CLTV allows total debt up to 75 units. Subtract the 45 you already owe, and the line tops out near 30 units, or about 30% of the home’s value. Line-size and credit limits can bring that down further.
Step 2: Borrower qualification. SmartAsset says lenders check your income and existing debts before approving a line. Debt-to-income, or DTI, compares your monthly debts to your monthly income. On the network, the maximum DTI is 50%. For credit scores from 600 to 679 the limit is 45%, so a ratio above 45% requires a score of at least 680. The lender qualifies you on the interest-only payment calculated on the maximum draw, not the amount you plan to use.
Step 3: Valuation. Lines at or below $500,000 ordinarily use an automated valuation with no traditional appraisal. A higher CLTV may call for a second valuation, and you can request a full appraisal in any case. A full appraisal is required on every line above $500,000.
Step 4: Draw and document. The draw lands in your account. The purchase lender then traces it as a source of funds. On the network’s programs, at least 75% of the line is drawn at closing, so interest starts accruing on most of it at once.
Step 5: The purchase lender decides. The new loan has to accept borrowed funds. SmartAsset notes that lenders generally want a larger down payment on a second home, and that an investment property may need even more. Treat borrowed money as three separate questions: the down payment, closing costs, and reserves. Lenders answer each one on its own terms, and some accept borrowed funds for one and not another. Ask before you draw.
Step 6: A repayment plan. One BiggerPockets investor argues that a line suits short-term use, and only if you can repay it within a year or two. The same investor calls a line-funded down payment held long term a poor idea. Treat that as one investor’s view, but it points at a real question: where does the payoff money come from?
What the Network’s Lines Look Like
The lines Lendmire places run on two wholesale programs. Each figure below belongs to the occupancy it names, and your credit profile moves the ceiling.
Primary residence. Leverage steps up with credit. A 720+ profile reaches 90% CLTV with a line up to $500,000. A 700+ profile reaches 85% CLTV up to $500,000. The 680 and 660 tiers also reach 85%. A 640 profile tops out at 80%, a 620 at 70%, and a 600 at 60%. For lines up to $750,000, 700+ and 720+ profiles cap at 75% CLTV. The minimum credit score is 600.
Second home. The ceiling reaches 90% CLTV only at 720+, with a line up to $500,000. The 700 and 680 tiers reach 85%, the 660 tier reaches 80%, and the 640 tier reaches 75%. The credit floor is 640, and the maximum line is $500,000.
Investment property. The ceiling is 70% CLTV on a line up to $500,000, with a 700 minimum credit score. Nothing on an investment property goes higher.
Three things follow from that. First, the most leverage comes from the home you live in. Second, a line above $500,000 is primary-residence only and caps at 75% CLTV. Third, that size needs a score of 700 or better (720 on the five-year-draw program described next) and a full appraisal.
Structure. These are standalone lines in first or second lien position. The three-year-draw program pairs a 3-year interest-only draw with a 17-year fully amortizing repayment. The five-year-draw program pairs a 5-year draw with a 25-year repayment. Investment lines run only the five-year structure. Pricing floats through both periods and never converts to fixed. Lines run from $25,000 to $750,000, and a subsequent draw is typically a $1,000 minimum where a program states one. A few states shorten the draw and repayment terms or add homestead rules, so confirm yours.
Credit and history. Credit is a single-bureau score tied to the primary wage earner, and the report can be no more than 90 days old at closing. A 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 or short sale at 4. The other program declines that history entirely.
Availability. These lines are available only in Lendmire’s 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 the 41-market DSCR footprint.
Qualification is subject to lender guidelines, credit approval, and property review. Programs change, and every file is underwritten individually.
Where the General Rule Breaks
The general rule says a line on your home can fund a purchase elsewhere. These edge cases bend it.
A line on a rental you already own. This is the hard version. Banks that write lines usually want a home you live in. Some investors open the line while the home is still their primary residence, then move out. The BiggerPockets hosts call this typically fine if the line stays open, but they say to check your line’s terms. It is investor commentary, not a rule. If you plan to convert your home to a rental, open the line before you list or move.
A property held in an LLC. Under the network’s equity-line programs, LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. Title must sit with you personally or in a revocable living trust. A property already deeded to an LLC needs a vesting change, or a DSCR cash-out instead, subject to program terms. This is the sharpest structural difference from a DSCR loan.
A home that is listed for sale. A property listed for sale, or listed within the past 60 days, is ineligible in several states. Do not list first and borrow second.
Property type. Single-family, 2-4 units, PUDs, townhomes, and condominiums, including non-warrantable condos, are eligible. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural zoning are not eligible on either program. Two- to four-unit homes need a 640 minimum on the five-year-draw program.
Several lines or many properties. A borrower is limited to three lines. Combined exposure caps at $2,000,000 on the three-year-draw program and $750,000 on the five-year-draw program. A borrower with more than 15 financed properties is not eligible.
The draw period ending. The CFPB booklet on home equity lines explains that when the draw period ends, you enter a repayment period. Payments can rise sharply at that point. Plan for the repayment payment on day one, not when the draw ends.
The Purchase Side: How a DSCR Loan Treats the New Property
Once the equity is in hand, the new house has to qualify on its own. For a rental, that usually means a DSCR loan. DSCR stands for debt service coverage ratio. It divides the property’s monthly rent by its monthly PITIA, which is principal, interest, taxes, insurance, and any association dues. Lendmire’s complete DSCR loans guide covers the full mechanics.
The ratio counts only the new property’s payment. Your equity line payment does not enter it, but it still comes out of your pocket. Rent was never underwritten to cover that payment. One BiggerPockets investor says the chance a line-funded deal cash-flows on its own is slim.
Clearing 1.00 is also not the same as positive cash flow. Repairs, vacancy, management, utilities, and capital expenses all sit outside the calculation.
Here is where the network’s purchase programs typically land:
- On a purchase, most files sit at 75%-80% LTV, which means 20%-25% down.
- Select high-leverage purchase programs reach 85% LTV (15% down) with roughly a 700+ score.
- Coverage of 1.00 is where many select programs start. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted.
- Credit floors reach 620 in parts of the network, most programs want about 660, and 700+ opens the strongest leverage tiers.
- Loans run up to $3,000,000 on standard programs (smaller balances available through select lenders), and reserves commonly run around 6 months of PITIA. They vary by lender, leverage, loan size, and transaction type.
A bigger down payment lowers the payment and can lift coverage. It does not erase leverage caps, credit floors, reserve rules, or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage.
A line-funded down payment adds one more wrinkle. Because you borrowed the 20% to 25%, your real leverage across both properties is higher than the purchase LTV shows. A BiggerPockets thread flags the risk: a property paid for with a line plus a mortgage has little equity, so a downturn could push both properties underwater.
Skip the Line? Alternatives to Compare
If the bank route stalls, the alternatives share one thread: they borrow against equity you already hold.
A cash-out refinance on a rental you already own can fund the next down payment. On standard rentals, cash-out typically tops out around 75% LTV across most of the network, and about 6 months of seasoning is the common expectation. It also qualifies primarily on property-level rental income covering the payment, subject to lender guidelines.
Lendmire also covers the investor-side version of this question in its piece Banks That Offer a DSCR HELOC on One Rental to Buy Another Investment Property.
A home equity loan is a lump sum with a fixed schedule, while a line is revolving. A bridge loan is short-term money meant to be repaid when a property sells. The right choice depends on how long you need the money and what you will repay it with.
Good Fit, Poor Fit
A line on your home tends to fit when:
- You have substantial equity and a credit profile that reaches a leverage tier you can use.
- You can repay the draw from your own income, not from the new property’s rent.
- The purchase lender has confirmed it accepts borrowed funds for the pieces you plan to cover.
It tends to fit poorly when:
- The new rent is your only plan to repay the line.
- Your DTI sits near the limit before the new payment is added.
- Your home equity is thin after the combined cap is applied.
- You cannot afford the larger primary-home payment if the variable pricing moves up.
The risk is concrete. The line is secured by your home, so SmartAsset points out that a missed line payment puts your primary residence at risk.

Vesting: How title to a property is held, such as in your own name or in a revocable trust.
Frequently Asked Questions
Can I use a HELOC for a down payment on an investment property?
Often yes, but the purchase lender has the final say. It decides whether borrowed funds count toward the down payment, closing costs, or reserves, and those can be treated separately. Confirm the purchase lender’s rule before you draw anything.
Will a bank give me a HELOC on a rental property?
Many will not, per BiggerPockets. Within the network, an investment-property line is available only at a 700 minimum credit score, up to 70% CLTV, and up to $500,000. Lines on a primary residence reach higher leverage.
Is a HELOC rate fixed or variable?
Usually variable, which means payments can change. The CFPB says some lines let you convert part or all of the balance to a fixed rate. The lines Lendmire places through its network do not convert, because pricing floats through both the draw and repayment periods.
Does the HELOC payment count in the DSCR calculation?
The DSCR ratio compares the new property’s rent to that property’s own PITIA. Your line payment is a separate personal obligation. It still affects your DTI on the line itself and your own cash flow.
How much can I borrow against my home to buy another house?
It depends on your CLTV tier, your credit, and the home’s occupancy. On a primary residence, 90% CLTV exists only at a 720 profile with a line up to $500,000. Lines above $500,000 are primary-residence only and cap at 75% CLTV.
