The Quick Read: A home equity line of credit (HELOC) can fund the down payment on an investment house, but the line has to be in place before the purchase, and the pool of lenders willing to write a line secured by a rental is thin. The more common route is a line on your primary home. Eligibility depends on your equity, credit, and the property that secures the line.
- A line cannot be secured by the house you are buying, because the line must close before you make the purchase.
- Lines secured by a rental are written by fewer lenders and carry stricter terms than lines secured by a primary home.
- Across Lendmire’s wholesale network, an investment-property line tops out at 70% CLTV (combined loan-to-value, explained below) and a $500,000 line, with a 700 minimum credit profile.
- Lines secured by a primary residence or second home can reach 90% CLTV, and only at a 720 or better credit profile.
- The purchase lender decides separately whether it will accept borrowed money as your down payment.
Two Different Products Share This Question
Two separate structures hide behind this search, and they work differently. In the first, you borrow against the home you live in and use the cash as a down payment. In the second, you borrow against a rental you already own. Yahoo Finance describes the first approach: homeowners can use equity in a primary residence for a down payment on an investment property.
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.
| Factor | Line on Your Primary Home | Line on a Rental You Own |
|---|---|---|
| Collateral | The home you live in | The existing rental |
| Network ceiling | 90% CLTV at 720+ | 70% CLTV |
| Max line size | Up to $750,000 | Up to $500,000 |
| Main risk | Your residence secures the debt | The rental secures the debt |
| Lender pool | Wider | Narrower |
Lines above $500,000 are available only on a primary residence. They require a credit profile of at least 700 (720 on the longer-runway structure), cap at 75% CLTV, and need a full appraisal. The 90% CLTV figure applies only to primary-residence and second-home lines at a 720 or better credit profile.
Lendmire is a mortgage broker, not a lender. It works with select wholesale HELOC lenders, and the figures above come from those lenders’ guidelines. They are ranges, not promises, and every file is reviewed individually.
Why So Few Banks Write a Line on a Rental
NerdWallet notes that a HELOC on an investment property is not offered by every lender and that the qualification requirements are strict. It also says you may face a smaller pool of lenders and a lower borrowing limit than you would against your primary home.
Community banks and credit unions may be more willing to consider rental collateral, but their rules differ by institution and by state. No registry lists who currently offers the product, so any list you find online goes stale. That is why this article names no institutions.
A broker changes the search. Instead of calling lender after lender, you give one broker the file. The broker matches your property, equity, credit, and goals to the wholesale programs that fit. The best lender for you depends on your credit profile, the leverage you need, and the property type.
How Underwriting Treats the Line, Step by Step
1. Collateral is chosen. It is either your primary home or a rental you already hold. The line must be in place before the purchase, so it cannot sit on the property you plan to buy.
2. Credit is pulled. On this network, the line is underwritten to a single-bureau score keyed to the primary wage earner. The report can be no more than 90 days old at closing.
3. Income and debt are tested. Bankrate explains that lenders weigh both the borrower’s creditworthiness and the property’s financials. Market surveys report debt-to-income limits in a 40% to 50% range. Across the network, the maximum is 50%, calculated on the interest-only payment at the maximum draw.
4. The property is valued. Lines at or below $500,000 ordinarily use an automated valuation. That means an investment line commonly closes with no traditional appraisal. You can still request a full appraisal.
5. The line closes and you draw. On a network investment line, at least 75% of the line is typically drawn at closing. Funds land in your bank account.
6. The purchase proceeds. The money becomes your down payment and closing costs in a separate transaction.
Experian adds that you will likely need a higher credit score, lower debt-to-income, and stronger reserves than for a primary-home line.
What Wholesale Lenders in the Network Look For
These are the program ranges Lendmire sees for equity lines. Terms vary by lender and are subject to lender guidelines.
Investment property line
- Maximum 70% CLTV, reached at both 720+ and 700+ credit profiles. A 700 score is the floor, and a higher score buys eligibility rather than more leverage.
- Line sizes run from $25,000 up to a $500,000 ceiling on an investment property.
- The structure is a 5-year interest-only draw followed by a 25-year fully amortizing repayment. The line floats and never converts to a fixed amount.
- The line can sit in first or second lien position.
Primary residence or second home line
- Up to 90% CLTV, only at a 720 or better credit profile.
- Lines above $500,000 are primary-residence only. They need a 700 or better credit profile (720 on the longer-runway structure) and cap at 75% CLTV on a primary residence. They also require a full appraisal.
- Two draw structures exist: a 3-year interest-only draw with a 17-year repayment, or a 5-year draw with a 25-year repayment.
Property and borrower rules
- Eligible properties include single-family homes, 2-4 units, townhomes, PUDs, and condominiums, including non-warrantable ones.
- Not eligible: manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, or agricultural zoning.
- Title must be held by you personally or by a revocable living trust. LLCs cannot hold title on these lines.
- A borrower is limited to three lines. Anyone with more than 15 financed properties is not eligible.
- A bankruptcy needs four years of seasoning from discharge. On investment files, a foreclosure needs seven years, and a deed-in-lieu or short sale needs four.
Lendmire’s HELOC lenders operate in 16 full-service states. That is narrower than its DSCR investor footprint of 41 markets, including Washington, D.C.
How the Purchase Lender Treats the Borrowed Down Payment
Getting the line approved is only half the job. The loan that buys the house has its own rules. Across the wholesale network, DSCR purchase programs typically land at 75% to 80% LTV on a purchase, which means 20% to 25% down. Select programs reach 85% LTV on a purchase at a 700+ credit profile, with 15% down. The complete DSCR loans guide walks through how those loans qualify.
A DSCR (debt service coverage ratio) loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. Three things matter for a borrowed down payment:
- Acceptance varies. Many programs accept a documented draw. A few cap the borrowed share, and the strictest overlays want some unborrowed cash in the file.
- Reserves are a separate pot. Reserves are the cash you hold after closing. Borrowed funds are commonly excluded from reserves, so keep real savings aside.
- The paper trail matters. Keep the line agreement, the draw statement, and the bank deposit record to show where the money came from.
Your HELOC payment does not count in the DSCR ratio. DSCR compares rent to the property’s PITIA only (principal, interest, taxes, insurance, and any association dues). It still comes out of your pocket each month, and rent was never asked to cover it. Clearing 1.00 on coverage is also not the same as positive cash flow. Repairs, vacancy, management, and utilities all sit outside that calculation.
For context, 1.00 is where many select programs start. A separate path through select lenders in the network takes coverage below 1.00, with leverage and terms adjusted. Credit tiers matter too. Most programs want around 660, and 700+ opens the strongest leverage.
A Worked Example in Percentages
Picture an investor with a 750 credit profile who owes 50% of her primary home’s value on the first mortgage. The network’s 90% CLTV ceiling at a 720 or better profile means the line could, in theory, reach 40% of the home’s value. That is subject to the line size limits above and full file review.
She does not need that much. She wants to buy a rental at 75% LTV on a purchase, which means a 25% down payment. The line covers the down payment and closing costs, and her own savings cover reserves. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
The rental’s rent covers its full PITIA at roughly 1.15x. That clears a 1.00 floor with some room. It says nothing about the line payment, which she pays from her own income. She stress-tests it first. If the line payment rises with a variable adjustment, can she still carry both debts if the rental sits empty for a stretch?
The structure only works if she can answer yes. That is the real investor decision: enough equity and enough rental coverage, plus a plan for the line payment.
Where the General Rule Breaks
The line cannot fund its own down payment. A line on a rental must sit on a rental you already hold. You cannot open it on the house you are about to buy.
Occupancy and ownership trip people up. If your rental is deeded to an LLC, the line cannot go on it. These lines require individual or revocable trust title. A property already in an LLC needs a vesting change, or a DSCR cash-out refinance instead. A rental that is listed for sale, or listed within the past 60 days, is ineligible in several states. NerdWallet also notes that some lenders restrict lines by location and by whether the home is rented out year-round.
Portfolio size caps appear. The network allows three lines per borrower and excludes borrowers with more than 15 financed properties. An investor with a large portfolio may find the door closed at the line stage.
Leverage stacks. A down payment funded by borrowing lowers the new loan amount, but it can raise total leverage across everything you own. There is no true zero-down DSCR purchase. The line only changes where the down payment comes from.
Approval does not transfer. Getting approved for the line does not mean the purchase lender will accept the draw as your down payment. Each lender makes that call separately, and a purchase lender’s refusal of borrowed funds can stand even when the line itself is fully approved.
Property types drop out. Manufactured homes, log homes, and barndominiums are not offered in the DSCR purchase programs. They are also not eligible for the line.
Risks You Should Size Before You Draw
Variable pricing. The line floats and never converts to a fixed structure. SuperMoney flags the payment reset at the end of the draw period as potentially substantial, and the network’s investment line moves from interest-only to fully amortizing after year five.
Foreclosure exposure. On a line secured by a rental, Experian notes that the lender can foreclose on that property. On a line secured by your home, the residence is at risk. Know which one you are signing.
Added debt. You are carrying two obligations for one new asset. Rental-collateral lines often price higher than lines secured by a primary home, which makes the stress test more important.
HELOC or Something Else?
| Option | What It Does | Best Fit |
|---|---|---|
| HELOC on primary home | Draws equity for the down payment | Strong home equity, 720+ credit |
| HELOC on a rental | Draws equity from a rental you own | Individually titled rental, 700+ credit |
| Cash-out refinance | Replaces the existing first mortgage | Standard rental, about 75% LTV on a cash-out, about 6 months seasoning |
| Home equity loan | One lump sum, fixed repayment | Borrowers who want one draw |
NerdWallet’s own guidance points rental owners who want to tap equity toward a DSCR second mortgage as an alternative. For a deeper look at the rental-side version, see Lendmire’s piece Banks That Offer a DSCR HELOC to Buy Investment Property Using Rental Equity.
Questions to Ask Any Bank Before You Apply
- Do you write lines secured by a rental, or only by a primary residence?
- What is your maximum combined loan-to-value for an investment property?
- Do you accept an LLC or a trust on title?
- Is there a cap on how many properties I can own or finance?
- Does the line convert to a fixed payment, or does it float?
- When does the draw period end, and what does the payment do after that?
- Will you require a full appraisal, or an automated valuation?
- Does a recent purchase or cash-out refinance on the rental make it ineligible?
Key Terms Defined
HELOC: A revolving credit line secured by property equity, with a draw period followed by a repayment period.
CLTV (combined loan-to-value): All loans secured by a property, added together and divided by its value.
DSCR: A ratio of the property’s monthly rent to its full monthly obligation, used to judge a rental purchase.
PITIA: Principal, interest, taxes, insurance, and any association dues on a property.
Reserves: Cash you hold after closing that a lender may require as a cushion.
Seasoning: The time a lender wants between two events, such as buying a property and refinancing it.
Frequently Asked Questions
Can I use a HELOC to pay for the entire investment house?
It is possible in principle, but the line size and CLTV limits usually make a down payment the realistic use. Network investment lines cap at $500,000 and 70% CLTV. A purchase lender still expects a down payment on a purchase, typically 20% to 25% on most files.
Which banks offer a HELOC on a rental property?
No authoritative registry exists, and availability changes by state and over time. Large retail banks often decline rental collateral. Community banks and credit unions are more likely to consider it. A broker can match your file to wholesale lenders that write the product.
Will the DSCR lender count my HELOC payment against me?
A HELOC payment is not part of the DSCR ratio, which compares rent to the property’s PITIA only. The payment is still real money leaving your account each month. Test your cash flow with and without that payment.
Can an LLC take out this kind of line?
No. On this network, the borrower must hold title individually or in a revocable living trust. A rental already in an LLC needs a vesting change, or a DSCR cash-out refinance instead, subject to program terms.
What credit score do I need?
An investment-property line needs at least a 700 profile, and 720 or better opens the 90% CLTV ceiling on a primary residence or second home. The DSCR purchase loan has its own floor. Most programs want around 660, and a 620 floor exists in parts of the network.
