The Quick Read: An investment property HELOC can fund a rental down payment, but the right provider depends on which property secures the line, your credit profile, and how the purchase lender treats borrowed funds, so no single provider is the top choice for every borrower. Lendmire is a mortgage broker, not a lender. It does not rank or name lenders. It matches your scenario to the wholesale programs that fit.
- A line on a rental property tops out at 70% CLTV (combined loan-to-value) and $500,000 across the network, with a 700 minimum credit score, subject to lender guidelines.
- A line on your primary home can reach higher leverage, up to 90% CLTV, but only with a 720-or-better credit profile. A primary-home line above $500,000 caps at 75% CLTV.
- Your DSCR purchase loan looks at the new property’s rent against its own payment. The HELOC payment sits outside that ratio, so your other income has to carry it.
- Purchase lenders differ on borrowed down payments. Some accept a documented draw in full. Others cap it or want some of your own seasoned cash.
Who Actually Writes These Lines?
Several kinds of lenders write home equity lines. They differ in what they will lend against and who they will lend to. A list of company names tells you little, because the right fit depends on your property, credit, and plan. The type of provider tells you more.
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.
| Provider type | Best for | Limits |
|---|---|---|
| Large retail lenders | Lines on your primary home | Rental collateral often declined |
| Credit unions | Members with strong local ties | Product menus and rules vary |
| Wholesale lenders (via a broker) | Rental or primary collateral | Each program has its own rules |
| DSCR lenders | The purchase loan itself | They do not write the line |
The last row trips up first-timers. A DSCR lender funds the rental purchase. It does not give you the equity line. You need two separate lenders and two separate approvals.
A broker shops several wholesale lenders at once. That is the practical edge. One lender may decline a rental as collateral while another writes it. Through select wholesale partners, Lendmire places a HELOC 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 its 41-market DSCR footprint, which includes Washington, D.C.
How Do You Pick a Provider Without a Ranked List?
Pick on fit, not fame. Five questions sort the field before you compare any terms.
1. Which property secures the line? A line on your home puts your home behind your investment. A line on a rental puts that rental at risk. Not every provider takes both.
2. How is title held? The network’s lines require title in your own name or in a revocable living trust. An LLC cannot hold title on the line.
3. What is your credit profile? Rental collateral starts at 700 on this network. Primary-home lines start lower.
4. What sits ahead of the line? An existing first mortgage uses up combined leverage before the line adds anything.
5. Does the line fit the purchase lender’s rules? Ask the DSCR lender how it treats borrowed down payments before you open the line.
The best program for your situation is the one that clears all five. A broker can check them side by side before you apply.
Step by Step: How Underwriting Treats Each Loan
You face two separate reviews. They look at different things, and each one ignores the other’s math.
Step 1: The line gets reviewed on equity and credit. The lender looks at the collateral property’s value, what you owe on it, and your credit. Lines at or below $500,000 usually use an automated valuation instead of a traditional appraisal. A borrower can still request a full appraisal. A Benzinga investor guide lists the usual paperwork: proof of income, tax returns, rental agreements, and proof of insurance.
Step 2: The line gets tested on debt-to-income. Across the network, the maximum DTI is 50%, and 45% for credit profiles from 600 to 679. The lender reviews your file on the interest-only payment calculated on the maximum draw. That is the full line, not only what you borrow today.
Step 3: You open the line before you need it. Open it and move the draw into a dedicated account. That keeps a clean paper trail from the line to the title company.
Step 4: The purchase loan gets reviewed on the property. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. DSCR means debt service coverage ratio: monthly rent divided by the full monthly payment (principal, interest, taxes, insurance, and any HOA dues). Your personal income is not the main test.
Step 5: The purchase lender checks where the cash came from. This is the source-of-funds review. The lender wants to see the draw leave the line and arrive at closing.
Step 6: The HELOC payment stays out of the DSCR. The ratio compares rent to the new property’s payment only. Your line payment must be covered by something else, such as salary or another rental’s cash flow.
One caution on that ratio. Clearing 1.00 does not mean positive cash flow. Repairs, vacancy, management, utilities, and capital expenses sit outside the calculation.
What Do the Network’s Line Requirements Look Like?
Requirements change with how the collateral is used. The figures below are typical ranges from select wholesale lenders in Lendmire’s network, subject to lender guidelines and full file review.
| Collateral | Max CLTV | Min credit | Line cap |
|---|---|---|---|
| Investment property | 70% | 700 | $500,000 |
| Second home | Up to 90% (720+ only) | 640 | $500,000 |
| Primary residence | Up to 90% (720+ only) | 600 | $750,000* |
*A line above $500,000 is primary-residence only. It needs a credit profile of at least 700 (720 if the borrower chooses the longer-runway structure, the one with a 5-year draw and 25-year repayment). It caps at 75% CLTV and requires a full appraisal.
On an investment property, a 720 score and a 700 score both reach 70% CLTV. Higher credit buys eligibility rather than extra leverage there. A 700 score is a hard floor with no tier below it.
Property type matters too. Single-family homes, 2-4 units, PUDs, townhomes, and condos (including non-warrantable condos) are eligible. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not.
Two more limits matter for repeat investors. A borrower is limited to three lines in total. A borrower who owns more than 15 financed properties is not eligible.
How the Draw and Repayment Periods Work
A HELOC is an open-end credit line that lets you borrow repeatedly against home equity, which is the home’s value minus what you owe. The Consumer Financial Protection Bureau explains that you can draw up to the limit during the draw period. Borrowing then stops and repayment begins. Payments are often significantly higher in repayment, and some lines can require the whole balance when repayment starts.
Experian reports that draws across the market typically run five to 10 years, usually followed by a 20-year repayment. On the network, a line on an investment property runs one structure only: a 5-year interest-only draw, then a 25-year fully amortizing repayment.
Primary residences and second homes also have a shorter option, with a 3-year draw and a 17-year repayment. Some states shorten both periods.
Three structural facts apply across the network:
- At least 75% of the line is drawn at closing.
- The line can sit in first or second lien position.
- Pricing floats during the draw and the repayment, and it never converts to fixed.
That last point matters for a rental plan. A floating payment makes long-term rental numbers harder to forecast. The larger risk is the step-up when the draw ends. Plan for the repayment payment on day one, not the interest-only payment.
Will the Purchase Lender Accept Borrowed Funds?
Programs split into a few camps. Some accept a documented draw as the entire down payment. Others cap the borrowed share. Others want part of the cash to be your own seasoned funds. Seasoning means the money has sat in your account long enough to show it is yours.
Do not try to hide a draw by letting it sit unspent for a while. Lenders review the documented trail. Plan for a clear one.
Reserves vary by lender, leverage, loan size, and transaction type. They commonly run around 6 months of PITIA, which is principal, interest, taxes, insurance, and association dues. Conservative rate-and-term files at modest leverage under $1,500,000 can see reserves waived. Loans above that size typically step up to around 9 months.
Agency mortgage rules sometimes allow borrowed funds for a down payment. DSCR loans are not agency products, so each lender sets its own rule. Do not assume the two match.
A Worked Example: Savings, Partial Line, Full Line
These are modeled assumptions, not market data. Say you buy a rental on a standard purchase at 75% LTV, which means a 25% down payment. Most DSCR purchase files land between 75% and 80% LTV, and select programs reach 85% LTV with roughly a 700-plus score. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.
| Down payment source | Share financed across liens | Personal cash-flow load |
|---|---|---|
| All savings | 75% | None from a line |
| Half from the line | 87.5% | Moderate |
| All from the line | 100% | Heavy |
Look at the middle row. The purchase loan covers 75% of the price. The line covers half of the 25% down payment. Together, 87.5% of the price is borrowed. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.
Look at the last row. A fully borrowed down payment leaves you financed near 100% across two liens. The rent has to carry the purchase loan, and your other income has to carry the line payment. Closing costs add to the draw you need.
The DSCR on the new property can still look strong in every row, since the ratio ignores the line. A larger down payment lowers the monthly payment and can lift the ratio. It never erases leverage caps, credit floors, reserve rules, or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage.
On coverage, 1.00 is where many select programs start. A separate select-lender path takes coverage below 1.00 with leverage and terms adjusted. Stronger ratios open better pricing and leverage. The complete DSCR loans guide walks through how coverage drives those tiers.
Where the General Rule Breaks
Several edge cases change the answer.
Your LLC owns the rental. The line cannot go on a property deeded to an LLC, a corporation, a partnership, or an irrevocable, blind, or land trust. You would need a vesting change first. A DSCR cash-out refinance can be the better route, since DSCR loans can close in an LLC name, subject to lender program eligibility.
The prepayment penalty collides with your exit. Many DSCR loans carry a prepayment penalty, a fee for paying the loan off early. A plan that opens a line, buys, and refinances out soon after can run into it. Check the penalty terms before you commit to a recycle plan.
You stack leverage. A high-leverage purchase loan plus a borrowed down payment leaves almost no equity cushion. A modest price drop can erase it.
Your payment can change. The Nasdaq and SmartAsset explainer points out that HELOCs are usually variable-rate and that a line on your home puts that home at risk if you cannot pay.
The line is too small for a repeat strategy. Lines cap at $500,000 on rental collateral, and borrowers are limited to three lines. A line alone will not carry an unlimited run of deals.
The property type is not offered. Manufactured homes, log homes, and barndominiums are not offered through the network’s DSCR programs. A HELOC does not change that.
Tax treatment can depend on how the funds are used and how the property is held; borrowers should keep clear records and speak with a qualified tax professional before relying on any deduction.
When This Is a Bad Idea (and What to Do Instead)
Skip the line if you cannot cover its payment from income outside the new rental. Skip it if the purchase lender will not accept borrowed funds. Skip it if your plan depends on a quick refinance into a loan with a prepayment penalty.
Declined? Three fallback paths work for many investors:
- Choose a different collateral property. A line on your primary home may fit when a rental will not.
- Use a DSCR cash-out refinance on an existing rental. It qualifies primarily on the property’s rental income, so your personal DTI matters less. The network tops out around 75% LTV on cash-out, with about 6 months of seasoning as the common expectation.
- Lower the purchase leverage. A bigger own-cash share shrinks the amount you need to borrow. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
Key Terms Defined
CLTV: Combined loan-to-value, the total of all loans on a property divided by its value.
DSCR: Debt service coverage ratio, a property’s monthly rent divided by its full monthly payment.
Seasoning: The time money or a loan has been in place before a lender will count it.
Draw period: The stretch when you can borrow from the line, usually with interest-only payments.
Source of funds: The paper trail showing where your down payment came from.
Frequently Asked Questions
Can I use a HELOC on my primary home for a rental down payment?
Yes, if the line and the purchase lender both allow it. Primary-residence lines start at a 600 minimum score on the network, and the 90% CLTV ceiling applies only at 720 or better. The purchase lender then decides how much of the draw it counts toward the down payment. Ask before you open the line.
Do my HELOC payments count against my DSCR?
No. The ratio compares the new property’s rent to its own payment. The line payment counts in the DTI test for the line itself, and it must be covered from income outside the new property.
Can an LLC hold title on the line?
No. A property already deeded to an LLC needs a vesting change, or a DSCR cash-out refinance instead.
How much of the line do I have to draw at closing?
At least 75% of the line is drawn at closing on the network’s programs. Size the line to what you will actually use, since the interest-only payment is qualified on the maximum draw.
Will a HELOC cover the whole rental purchase?
Not through a DSCR purchase. A line is built to cover the down payment, closing costs, and sometimes a repair buffer. The purchase loan covers the rest.
