The Quick Read: A HELOC can fund the down payment on a second rental, but the line is its own loan with its own credit, equity, and payment tests, and the purchase lender still reviews where the cash came from. The file has to clear both. A line secured by the rental itself is a narrower product than a line secured by your home.
- On Lendmire’s network, an investment-property line tops out at 70% CLTV and $500,000, with a 700 credit minimum.
- A line on a primary residence can reach 90% CLTV, but only at a 720-or-better credit profile.
- At least 75% of the line is drawn at closing, so a large “just in case” line costs interest from day one.
- An LLC cannot hold title on the line. Many investors discover this late.
- Clearing 1.00 on the next rental’s DSCR does not mean positive cash flow. It compares rent to the monthly obligation only.
Are You Actually Ready for a Second Rental?
Readiness is a set of numbers, not a feeling. A second rental is a good fit when the first property is stable, your reserves survive a bad quarter, and the new purchase still works after you add the HELOC payment. Five checks cover most of it.
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.
1. The first rental runs on its own. It has a signed lease or a clean rent history, and you have handled at least one turnover.
2. The new property clears coverage by itself. On most DSCR purchase files the property’s rent has to cover its own payment. A coverage ratio of 1.00 is where 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.
3. Your personal debt ratio absorbs the new line. The HELOC is underwritten on you, not the rental. The network’s 50% maximum DTI applies, and it is figured on the interest-only payment calculated on the maximum draw.
4. Reserves stay intact after the down payment. The purchase lender commonly looks for about 6 months of PITIA in reserves, though this varies by lender, leverage, and loan size. Draining cash into the down payment and then borrowing against your house for reserves is a common way to fail this test.
5. You can carry both payments through a vacancy. If the rental sits empty, the HELOC payment and the purchase loan payment are still due.
The fifth check is the one investors skip. Rent has to cover the purchase loan on paper, but you have to cover the HELOC out of pocket if the unit goes dark.
Which Property Secures the Line?
The answer is the biggest decision in the file. “Rental property HELOC” describes two different products, and they carry different risk.
| Factor | Line on your rental | Line on your primary home |
|---|---|---|
| Collateral at risk | The rental | Your home |
| Network CLTV ceiling | 70% | Up to 90% at 720+ |
| Minimum credit | 700 | Lower floors exist (600 program floor) |
| Maximum line | $500,000 | Up to $750,000 |
| Title | Individual or revocable trust | Individual or revocable trust |
| Typical use | Repairs, reserves, a purchase | Down payment on the next rental |
Every figure is subject to lender guidelines and full file review. The network’s investment line is a two-tier table. Credit at 700 and credit at 720 both reach 70% CLTV, so a higher score buys eligibility, not extra leverage. Because the line caps at $500,000, it sits in the automated-valuation lane, and a traditional appraisal is not ordinarily part of the file. A borrower can still request one.
The primary-home route is the common one for a second-rental buyer, since it has the higher ceiling. The tradeoff is where the risk lands. If the payments stop, the lender’s claim is on the house you live in, not the rental you bought.
How Does a HELOC Work?
A HELOC is an open-end line of credit. The Consumer Financial Protection Bureau describes it as a line that lets you borrow repeatedly against home equity, which is the property value minus what you owe on the mortgage. You can spend up to the limit during the draw period, and the CFPB gives 10 years as an example of how long one can last. The line usually carries a variable rate, though some lenders let you convert part or all of the balance to a fixed rate.
Two mechanics matter most to an investor.
First, you pay interest only on what you draw. The Federal Trade Commission explains that payments run on the amount borrowed, not the full amount available. On this network, that benefit is smaller than it sounds, because at least 75% of the line is drawn at closing.
Second, payments can change without a new draw. The CFPB’s HELOC booklet says a variable-rate plan can move your monthly payment even if you borrow nothing more. It also says a repayment period, often ten or fifteen years, begins when the draw period ends. Plan for that step-up before you sign.
Key Terms Defined
CLTV (combined loan-to-value): The first mortgage plus the new line, divided by the appraised value of the property securing them.
Draw period: The stretch when you can borrow from the line and pay interest only.
Repayment period: The stretch after the draw ends, when principal and interest are both due.
PITIA: Principal, interest, taxes, insurance, and association dues. This is the payment DSCR measures rent against.
DSCR: Monthly rent divided by the PITIA on the property, used on investor loans in place of personal income review.
Vesting: The name or entity that holds legal title to the property.
How Underwriting Treats a Rental-Property HELOC, Step by Step
An investment-property HELOC is a personal-credit loan. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. A HELOC looks at you first. Here is the sequence.
1. Collateral and vesting. The property must be held by you as an individual or by an inter vivos revocable living trust. Fee simple and leasehold are both acceptable.
2. Equity test. The reviewer adds your first mortgage and the requested line, then divides by the valuation. On an investment property the ceiling is 70% CLTV. On a primary residence it reaches 90% CLTV only with a 720-or-better credit profile.
3. Credit pull. A single-bureau score keyed to the primary wage earner, no more than 90 days old at closing, with no rescores. An investment line needs 700 or better.
4. Debt ratio. DTI maxes at 50%. A ratio above 45% requires a 680 minimum, and the payment is calculated on the maximum draw, not your planned draw.
5. Valuation. Lines at or below $500,000 ordinarily use an automated valuation. A higher CLTV may call for a secondary valuation. A full appraisal is required on every line above $500,000.
6. Draw at closing. At least 75% of the line is drawn when the loan funds. Later draws after closing carry a $1,000 minimum in most places.
The network does not set a numeric credit floor for the primary-home route as high as 700. The program floor is 600, and the tradeline and housing-history standards tighten as the structure changes. A lower score also lowers the CLTV tier you can reach.
How Much Can You Actually Draw?
Run the math in percentages, not dollars. Say your primary home carries a first mortgage equal to 55% of its appraised value, and you have a 720-or-better profile. The 90% CLTV ceiling leaves about 35% of value as the outer limit for a new line. That is the ceiling, not the amount to take. Lenders and the purchase underwriter both look at what happens when that line is spent.
Now run the same logic on a rental you own, with a first mortgage at 50% of value. A 70% CLTV ceiling leaves 20% of value as the outer limit. The line size is also capped at $500,000, and there is no investment tier above that cap.
Next, size the draw against the purchase. A 20% down payment on a purchase fits the 75% to 80% LTV range most DSCR purchase files use. A select program reaches 85% LTV, which is 15% down, with roughly a 700-plus score. Every point of down payment you replace with HELOC money is a point of new debt you have to carry on a floating payment. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.
Because 75% of the line draws at closing, open the line near the amount you will use. Opening a large line for flexibility locks in interest on money you did not need.
Investor discussions on BiggerPockets describe a 10% down payment on a purchase sourced from a primary-residence HELOC, and note that borrowed funds are generally allowed as a down-payment source. That matches what a broker sees across the network. The purchase lender still applies its own down payment, reserve, and source-of-funds rules, so disclose the line up front.
Structures and Variations
The draw structure depends on the occupancy of the property securing the line.
- Investment property: one structure only. A 5-year interest-only draw, then a 25-year fully amortizing repayment.
- Primary residence or second home: two structures. A 3-year interest-only draw with a 17-year repayment, or a 5-year draw with a 25-year repayment. The 5-year structure gives a longer runway before the payment steps up.
Both structures can sit in first or second lien position, and pricing floats through the draw and the repayment period. It never converts to fixed. A fixed-rate conversion option is something lenders sometimes offer. This network’s lines do not.
Credit and DTI also vary by structure. The longer-runway 5-year structure uses a two-tradeline standard, either two tradelines seasoned 12 months or one seasoned 24. It also applies housing-history rules across all financed properties. A bankruptcy needs 4 years of seasoning from discharge or dismissal. Foreclosure history on an investment property follows a 7-year path, and a deed-in-lieu, pre-foreclosure, or short sale follows 4 years.
Eligible properties include single-family, 2-4 units, PUD, townhome, and condominium, including non-warrantable condos. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned property are not eligible.
Where the General Rule Breaks
The standard path works for an investor with a personally held rental and a clear title. Several edge cases trip files.
The LLC problem. Many investors hold rentals in an LLC for liability reasons. An LLC, a corporation, a partnership, or an irrevocable, blind, or land trust cannot hold title on the line. A property already deeded to an LLC needs a vesting change before it can secure the line, or a DSCR cash-out refinance as the alternative. DSCR loans to LLC-titled borrowers are available subject to lender program eligibility, and that is the sharpest structural difference between the two products.
Availability. The home equity line is offered only in Lendmire’s 16 full-service states, a narrower footprint than the 41-market DSCR platform. An investor in a DSCR-eligible state may find the line unavailable and the cash-out refinance the only route.
Exposure limits. A borrower is limited to three lines, and combined exposure caps between $750,000 and $2,000,000 depending on the program. A borrower with more than 15 financed properties is not eligible. Investors scaling past a handful of rentals hit these limits before they hit a credit problem.
The payment is qualified on the maximum draw. Even if you plan to draw only the required 75%, the debt ratio uses the full line. Size the line to the amount you intend to use.
Self-employed borrowers. Income is reviewed on documented income under the applicable program, subject to lender guidelines. The business bank-account deposit analysis needs a 680, but an investment line already floors at 700, so bank-statement income is never the binding constraint on that route.
The tax trap. Tax treatment can depend on how the funds are used and how the property is held; investors should keep clear records and speak with a qualified tax professional before relying on any deduction.
HELOC, DSCR Cash-Out, or Cash?
This is the decision most second-rental buyers actually face. The table compares the three.
| Factor | HELOC | DSCR cash-out | All cash |
|---|---|---|---|
| Underwritten on | You (credit, DTI) | Property rent vs. PITIA | Nothing |
| Network leverage | 70% CLTV on investment | 75% LTV on standard rentals | None |
| First mortgage | Left in place | Replaced | N/A |
| Payment behavior | Floating | Fixed structures available | None |
| Main risk | Floating payment on your home | New first lien resets terms | Liquidity drained |
A DSCR cash-out refinance tops out at 75% LTV on standard rentals and 70% on short-term-rental collateral, with about 6 months of seasoning as the common expectation. It replaces the first lien and qualifies primarily on rental income, so personal DTI is not the driver. A HELOC leaves the first mortgage untouched, which can matter when that loan carries terms you want to keep. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.
Lendmire’s piece on how a HELOC compares with a cash-out refinance on a rental walks through the tradeoffs in more depth.
When a HELOC Is the Wrong Tool
Skip the line in these cases.
- The rental is held in an LLC and you do not want to re-title it. Use a DSCR cash-out instead.
- Your debt ratio is already near 50%. The new line will push it over, and the 45% threshold already raises the credit requirement.
- Your reserves are thin. The line gives you a down payment, not a cushion.
- The purchase only clears 1.00 by a hair. DSCR compares rent to PITIA and nothing else. Repairs, vacancy, management, utilities, and capex sit outside the calculation, so a tight ratio plus a floating HELOC payment leaves almost no room.
- You are close to the property-count or three-line limit. Borrowing against your house for property number five is a different risk profile than for number two.
After Closing: Repay, Refinance, and Reload
The usual sequence is to open the line, draw, buy the second rental on a DSCR purchase loan, and then decide how to retire the line. Some investors repay it from a later DSCR cash-out on the first rental. Others carry it through the draw period and pay down principal as rents accumulate.
One cost to plan for is closing costs on both transactions. If you use the line for the down payment and refinance later, you pay closing costs at purchase and again at refinance. A BiggerPockets discussion of this strategy raises the same point. Count it before you commit.
The 5-year draw on an investment line is a short runway. Aim to have a plan for the line before the repayment phase begins and the payment steps up.
Our broader complete DSCR loans guide covers how the purchase side of this sequence works.
Frequently Asked Questions
Can I use a HELOC to buy a rental?
Usually, yes, as a down-payment source, provided the purchase lender permits borrowed funds and you disclose the line. The purchase loan applies its own down payment, reserve, and source-of-funds rules. A line cannot replace the purchase loan on the network’s investment programs.
Can I get a HELOC on a rental I already own?
Yes, through select lenders in the network, up to 70% CLTV and $500,000, with a 700 minimum credit score. The property must be held in your name or a revocable living trust, not an LLC. Availability is limited to the 16 states where the line is offered, and every file is underwritten individually.
Is a HELOC a second mortgage?
It can be. The network’s lines sit in first or second lien position. When placed behind an existing first mortgage, the line typically is a second lien, and the CLTV test counts both balances against the property value.
How much equity do I need?
Enough that the combined balances stay at or below the ceiling for the occupancy. That is 70% CLTV on an investment property and up to 90% CLTV on a primary residence with a 720-or-better profile. Put differently, an investment property needs at least 30% equity untouched.
Does a HELOC payment count against the new rental’s DSCR?
The rental’s DSCR measures rent against its own PITIA, so the HELOC payment is not in that ratio. It counts in your personal DTI, which the HELOC lender caps at 50%. The purchase lender may also review your overall debt picture.
