The Quick Read: A home equity line supplies cash but never buys the property, so the right lender depends on which property secures the line, how much combined leverage you need, and whether the purchase lender will accept borrowed down-payment funds. Lendmire is a mortgage broker, not a lender. It places these files with select wholesale lenders, so the answer comes from matching your situation to a program.
- Investment-property lines top out at 70% combined loan-to-value (CLTV), while primary-residence and second-home lines can reach 90% CLTV only at a 720 credit profile.
- Each line is a standalone loan in first or second lien position, and at least 75% of it is drawn at closing.
- The new home still needs its own financing, and a DSCR loan reads the rent against that home’s payment, not your personal income.
- Down-payment funds drawn from the line may leave little for the cash reserves a purchase lender wants to see.
- HELOC lines here run in Lendmire’s 16 full-service states, a narrower footprint than the 41-market DSCR network.
What Does a HELOC Actually Do in a Home Purchase?
A home equity line of credit (HELOC) is a revolving credit line secured by a property you already own. You draw cash from it, and you use that cash for the new purchase. The line never becomes the mortgage on the new home.
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.
Two separate loans are involved. The first is the line on your current property. The second is the purchase loan, or a cash offer, on the new home. For a rental, that second loan is usually a DSCR loan. (A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines.)
Investors use a line in three common ways:
1. Down payment. The draw funds the equity portion, and a purchase loan covers the rest.
2. Reserves. Some investors try to count the line as cash on hand. It rarely works, as covered below.
3. Bridge. The line funds the purchase before the old home sells, then gets repaid from the sale.
Each use raises a different question for the purchase lender. Each also leaves you carrying two obligations at once. That is the part most first-time users underestimate.
Key Terms Defined
CLTV (combined loan-to-value): All loans against a property added together, divided by its value. A first mortgage plus a line both count.
Draw period: The stretch when you can borrow from the line and pay interest only. After it ends, the balance amortizes.
PITIA: Principal, interest, taxes, insurance, and association dues. It is the full monthly obligation on a property.
DSCR (debt service coverage ratio): Monthly rent divided by PITIA. A ratio of 1.00 means rent equals the full payment.
Seasoning: The waiting period a lender wants between two events, such as buying a property and refinancing it, or depositing funds and using them.
Reserves: Liquid cash left after closing that a lender expects you to hold, commonly counted in months of PITIA.
What Do HELOC Lenders Look For When You Buy a New Home?
Across the wholesale network, these lenders underwrite the borrower and the equity in the property securing the line. They do not look at the new home. Here is the sequence.
Step 1: Occupancy and equity. The lender sorts the line by what the securing property is: your primary residence, a second home, or an investment property. Each has its own ceiling, covered in the next section.
Step 2: Credit. The program floor is a 600 credit profile, but each occupancy sets its own minimum. Lenders use a single-bureau score keyed to the primary wage earner. The report generally cannot be more than 90 days old at closing, and rescores are not allowed. Tradeline and housing-history standards vary by lender program.
Step 3: Debt-to-income. Maximum DTI is 50%. Profiles from 600 to 679 are held to 45%, and anything above 45% requires at least a 680. The calculation uses the interest-only payment on the maximum draw, not the amount you plan to borrow. Your personal income is part of this test, even though the new rental’s DSCR test is separate.
Step 4: Valuation. Lines at or below $500,000 ordinarily run an automated valuation with no traditional appraisal. A higher CLTV may trigger a secondary valuation. A full appraisal is required on every line above $500,000, and you can request one in any case.
Step 5: Property and title. The securing property must be a single-family home, a 2-4 unit, a PUD, a townhome, or a condo, including non-warrantable condos. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural zoning are not eligible.
Which Occupancy Fits? Ceilings by Property Type
The ceiling depends on the occupancy of the property securing the line, not the home you are buying. This table shows the top tier for each.
| Securing property | Top CLTV | Min credit | Max line |
|---|---|---|---|
| Primary residence | 90% at 720+ | 600 | $500,000 at 90% CLTV; $750,000 at 75% CLTV, 700+ (720 on the longer-runway program) |
| Second home | 90% at 720+ | 640 | $500,000 |
| Investment property | 70% (700+) | 700 | $500,000 |
Lower credit tiers step the ceiling down. On a primary residence, a 700 profile reaches 85% CLTV up to $500,000, and a 640 profile reaches 80%. A 620 profile reaches 70% CLTV up to $400,000. On a second home, 680 reaches 85% and 640 reaches 75%. Figures are subject to lender guidelines and a full file review, and they are not a commitment to lend.
A line above $500,000 is primary-residence only. It requires a credit profile of 700 or better (720 on the longer-runway draw structure, described below) and caps at 75% CLTV with a full appraisal.
Here is how the equity math runs in percentages. Say your primary residence carries a first mortgage equal to 55% of its value. A 720 profile with the 90% ceiling leaves up to 35% of the value in room, before the dollar caps apply. On an investment property with a first mortgage at 50% of value, the 70% ceiling leaves about 20%. Run your own numbers in the site’s illustrative calculator. It is an estimate, not a quote.
How Do the Draw Structures Work?
Two draw structures exist on primary residences and second homes:
- Shorter runway: a 3-year interest-only draw, then a 17-year fully amortizing repayment.
- Longer runway: a 5-year interest-only draw, then a 25-year fully amortizing repayment.
Investment-property lines use the 5-year draw and 25-year repayment structure only. A few states shorten both periods.
Two traits matter for a purchase. First, at least 75% of the line is drawn at closing. This is not a line you open and leave untouched, so you start paying interest on most of the balance immediately. Second, pricing floats through both the draw and the repayment period and never converts to fixed.
The CFPB’s plain-language HELOC page makes the same point about home equity lines generally. Payments are tied to a variable cost of borrowing and can change from month to month. Some lines also open with an unusually low introductory period, such as six months, according to the CFPB HELOC booklet. A payment that looks easy in month three can look different in month eight.
After closing, the minimum subsequent draw is $1,000 on the longer-runway structure.
How Does the Purchase Lender Treat Borrowed Cash?
This is where files succeed or stall. The line lender cares about your equity. The purchase lender cares where your down payment came from.
Across the DSCR programs in the network, treatment of borrowed funds varies. Some accept documented line proceeds as down-payment money. Others cap the borrowed share and want part of the down payment from your own seasoned cash. Expect to document the draw with the line agreement or statement, plus bank statements showing the deposit.
Three practical rules follow:
- An open balance is not reserves. Available credit on a line does not count as cash. Reserves are commonly around 6 months of PITIA on a DSCR purchase, but they vary by lender, leverage, loan size, and transaction type.
- Borrowed money often cannot do double duty. Cash that funds the down payment usually cannot also be counted as the reserves, so keep some money outside the line.
- Unsecured borrowing is different. A personal loan or credit card advance is not a HELOC, and lenders generally do not accept it for the down payment. Gift funds on an investment purchase are also often restricted.
Confirm with the purchase lender, before you draw, that borrowed funds are accepted. A broker that shops several wholesale lenders can ask that question for you up front.
How Does the DSCR Loan Treat Your New Rental?
If the new home is a rental, the purchase loan is underwritten as its own transaction. DSCR loans are designed for non-owner-occupied investment properties. Because they are business-purpose investor loans, they are reviewed differently from a standard owner-occupied mortgage.
Here is what the network typically looks like. Most purchases land at 75%-80% LTV, meaning 20%-25% down. Select programs reach 85% LTV (15% down) at roughly a 700+ score. Credit floors reach 620 in parts of the network, most programs want around 660, and 700+ unlocks the strongest leverage tiers. Loan sizes reach up to $3,000,000 on standard programs, with smaller balances available through select lenders, and above $2,500,000 the network generally holds to 30-year fixed structures.
Coverage of 1.00 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. No-ratio structures are available only through select lenders, generally for borrowers who already own a primary residence.
A larger down payment, even one funded by a line, shrinks the purchase loan and can lift the ratio. 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.
One more point. Clearing 1.00 is not the same as positive cash flow. Repairs, vacancy, management, utilities, and capital expenses all sit outside the calculation. The line payment sits outside it too, and your personal income carries that payment.
If the rental is a short-term rental, purchase leverage tops out at 75% LTV. Expect a 640+ score, about 12 months of hosting history, and a 1.00 coverage floor on purchases. 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. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.

Where the General Rule Breaks
Here are the edge cases that change the answer.
LLC-held property. The line cannot be secured by a property titled in an LLC, corporation, partnership, or an irrevocable, blind, or land trust. Title must sit with you individually or in an inter vivos revocable living trust. A property already deeded to an entity needs a vesting change, or a DSCR cash-out instead, subject to lender program eligibility. This is the sharpest structural difference from a DSCR loan.
Exposure limits. A borrower is limited to three lines. Combined exposure across those lines caps at $2,000,000 on the higher-leverage structure and $750,000 on the longer-runway structure. A borrower with more than 15 financed properties is not eligible. Separately, a single line above $500,000 is primary-residence only. It requires a credit profile of 700 or better (720 on the longer-runway structure), caps at 75% CLTV, and needs a full appraisal.
Listed properties. In some states, a property listed for sale, or listed within the past 60 days, is ineligible. That matters for bridge plans where you intend to sell the securing home. A line against a home you are about to list can be the wrong tool.
Credit events. A bankruptcy needs 4 years of seasoning from discharge or dismissal. Foreclosure history splits by occupancy and structure. On primary residences and second homes, one structure seasons a foreclosure in 7 years and a deed-in-lieu, pre-foreclosure, or short sale in 4. The other declines that history entirely. Investment files follow the 7-and-4-year path.
Lower credit. Sub-640 profiles are limited to single-family primary residences with a clean 12-month housing history under the longer-runway structure. Second homes floor at 640 and investment lines at 700.
Ineligible property types. The new home itself may be the problem. DSCR loans in the network are not offered on manufactured homes (single- and double-wide), log homes, or barndominiums.
A prepayment collision. If you plan to draw on the line, buy, and then cash-out refinance quickly, a prepayment penalty on the DSCR loan or the seasoning rule can disrupt the plan. A cash-out refinance tops out around 75% LTV across most of the network, with about 6 months of seasoning the common expectation. Plan the exit before the entry. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
How Do You Choose Among Lenders?
Lenders in the wholesale network differ on documentation, credit tiers, draw structure, and how they view borrowed funds. Which lenders fit depends on the file: the securing property, your credit profile, the leverage you need, and what the purchase lender will accept. A single bank sees only its own guidelines. A broker sees several.
Before you apply, ask these questions:
- Which occupancy tier does my securing property fall into, and what is the ceiling at my credit profile?
- Does the line fit the dollar cap I need, given that a line above $500,000 is primary-residence only?
- Will the purchase lender accept documented line proceeds, and for how much of the down payment?
- Does the new home’s financing require reserves that the line cannot supply?
- If the new home is a rental, how does coverage look, and would a sub-1.00 path through a select lender change leverage and terms?
Lendmire’s piece on investment-property HELOC providers covers the 70% CLTV investment tier in more depth. If you plan to buy first and sell later, its article on HELOC options when you buy a new home before selling covers that sequence.
What Does the Investor Decision Look Like?
Run the decision as a stress test, not a pitch.
Picture an investor with a primary residence and a first mortgage at about half its value. She qualifies for a line at a 720 profile. The duplex’s rent clears roughly 1.2x against its own PITIA. On paper the file works. In practice she now carries the first mortgage, the line payment, and the duplex loan. If the duplex sits vacant, her personal income carries the line payment alone.
Four layers of cash flow follow. The rental must cover its own payment, and your income must carry the line. Here is the honest version of each tradeoff:
- Liquidity: The line keeps savings and investments untouched. That is the main appeal.
- Concentration: You end up with two loans and one home at stake. Even if the rental performs, your residence remains collateral.
- Horizon: A line suits a short hold with a clear payoff plan. It is a poor fit for permanent financing, since the pricing floats and never converts to fixed.
- Sequencing: Get the line in place before you shop. Then confirm borrowed-fund acceptance with the purchase lender before you draw.

Frequently Asked Questions
Can I use a HELOC as the whole purchase price of a new home?
Sometimes, but it is rare for the full amount to work. The line can only reach the ceiling for the securing property, and at least 75% of it is drawn at closing. A fully borrowed purchase also leaves you with no equity in the new home and no reserves outside the line. Whether it works depends on the securing property, your credit profile, and what the purchase lender accepts.
Does the HELOC payment count against me on a DSCR loan?
Not in the DSCR ratio, which compares the rental’s rent to the rental’s own PITIA. The line payment still has to be paid from your personal cash flow. The line lender separately tests your DTI, which tops out at 50% and uses the interest-only payment on the maximum draw.
Can I take a line on a rental I already own to buy the next one?
Yes, within the investment-property tier. That tier tops out at 70% CLTV, requires a 700 credit profile, and caps the line at $500,000. It also uses only the 5-year draw and 25-year repayment structure. The property must be titled to you individually or in a revocable living trust, not an LLC.
Do all DSCR lenders accept borrowed down-payment funds?
No. Some accept documented line proceeds, while others cap the borrowed share and want part of the down payment from your own seasoned cash. The line balance never counts as reserves. Confirm in writing with the purchase lender before you draw.
What if my credit is below 700?
Primary residence and second-home lines still exist at lower tiers, with lower ceilings. A primary residence starts at a 600 credit profile, and a second home at 640. Investment lines require 700. Your file is reviewed under each lender’s guidelines.
