The Quick Read: The right program depends on which property secures the line. A home equity line does not buy the rental. It supplies cash that becomes the down payment on a separate purchase loan, usually a DSCR loan that reads the new property’s rent. Across Lendmire’s wholesale network, a line on a primary residence reaches much higher leverage than a line on an existing rental.
- A line on a primary home is usually the easier approval. A line on an investment property is a narrower product.
- On the network’s investment lines, the ceiling is 70% CLTV, with a 700 minimum credit score and a maximum line of $500,000.
- Primary-residence lines can reach 90% CLTV, but only at a 720-or-better credit profile.
- The DSCR purchase loan reads the new rent against the new payment. The line payment is not part of that ratio, yet the investor still has to carry it.
- Borrowed down payments are treated differently from program to program, so confirm that before the first draw.
An investor with a large brokerage account or a paid-down home often asks the same question. Can I buy the next rental without selling the holdings that are already working? Often the answer is yes, with real tradeoffs. This article walks through the mechanics, the underwriting, the structures, the edge cases, and the decision itself.
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.
What a HELOC Really Does in a Rental Purchase
A home equity line of credit (HELOC) is a revolving credit line secured by a property you already own. It sits behind your first mortgage, or in first position if the property is paid off. It does not appear on a purchase contract and it does not buy anything on its own.
In a rental purchase, two loans do two jobs:
1. The line supplies the cash. That cash covers the down payment, closing costs, and often some reserves.
2. The purchase loan buys the property. For most investors this is a DSCR loan, which qualifies primarily on property-level rental income covering the payment, subject to lender guidelines.
The structure keeps your stocks, funds, and other holdings invested. You avoid a sale and the decisions that come with it. What you add is debt, and your existing property becomes the collateral behind that debt.
Lendmire is a mortgage broker. It works with select wholesale partners and is not the lender. Its value here is matching the scenario to the program that fits, because the line lender and the purchase lender are two separate decisions. For background on the purchase side, see Lendmire’s complete DSCR loans guide.
Which Property Secures the Line?
This is the first fork, and it shapes everything after it. The line can sit on your primary home or on a rental you already own.
| Factor | Line on primary home | Line on existing rental |
|---|---|---|
| Top network CLTV | 90% at 720+ | 70% (hard ceiling) |
| Minimum credit (network) | 600 floor, tiered | 700 |
| Maximum line (network) | Up to $750,000 | $500,000 |
| Lender pool | Wider | Narrower |
| Main risk | Your home backs the debt | A rental backs the debt |
Outside the network, the market tells the same story. NerdWallet notes that a line on an investment property is possible but comes with a smaller pool of lenders and lower borrowing amounts than a primary home. It lists at least 20% equity as a typical requirement. Experian says rental lines are generally harder to qualify for and reports that lenders typically cap investment-property lines at 80% loan-to-value. That 80% is a market-wide statistic. Through Lendmire’s network, an investment-property line tops out at 70% CLTV.
CLTV counts every loan against the property. If your rental carries a mortgage, the line has to fit inside the 70% ceiling together with that balance. A rental with a small mortgage leaves room. A rental with a large one may leave almost none.
The tradeoff is blunt. A primary-home line gives you more leverage and an easier approval, but your home is the collateral. A rental-secured line keeps your home out of it, but it costs you leverage and lender choice. If the home is where your family lives, many investors accept the lower leverage. If you have a paid-off rental with strong equity, the rental line may be the cleaner choice.
How Underwriting Treats the Whole Plan
Two underwriting reviews run in sequence. The line is reviewed first. The purchase loan is reviewed second, and it sees the line.
Step 1: The line review
The line lender looks at the borrower and the securing property. On the network’s lines, the main tests are these:
- Credit. There is a 600 program floor, though an investment-property line starts at 700. A single score, keyed to the primary wage earner, is pulled and can be no more than 90 days old at closing.
- Debt-to-income. The maximum is 50%. It is 45% for profiles from 600 to 679, and anything above 45% needs a 680 minimum. The line is qualified on the interest-only payment calculated on the maximum draw.
- Equity. Combined loan-to-value must stay inside the occupancy-based ceiling.
- Valuation. Lines at or below $500,000 ordinarily use an automated valuation with no traditional appraisal. A full appraisal is required above $500,000, and a borrower may ask for one at any size.
Because an investment line caps at $500,000, it nearly always sits in the automated-valuation lane.
Step 2: The purchase review
The DSCR purchase lender reviews the new property. Most files land at 75%-80% LTV on a purchase, meaning 20%-25% down. Select programs reach 85% LTV at roughly a 700+ score. Credit floors run from 620 in parts of the network, to about 660 on most programs, to 700+ for the strongest leverage tiers. Reserves vary by lender, leverage, loan size, and transaction type. About six months of PITIA is common, and some conservative files at modest leverage are waived.
Here is the catch. The purchase lender wants to know where the down payment came from. Treatment of borrowed funds differs by lender and program. Some may want part of the cash to be the investor’s own unborrowed money. Others may cap the borrowed share. Treat down payment, closing costs, and reserves as three separate pots, and ask how each is treated before you draw anything.
A BiggerPockets thread shows the same caution from the investor side. One investor reports that banks often dislike a down payment that comes from a line, and that showing savings helps. That is anecdotal. It is not a rule, but it is the right question to ask.
Step 3: Sequence it correctly
1. Ask the purchase lender how it treats borrowed funds.
2. Open the line before the offer needs the money.
3. Draw the funds and keep the line agreement, the line statement, and the bank statement showing the deposit.
4. Close the DSCR purchase.
5. Pay down the line from rent and personal cash flow, or refinance the new property later.
The order matters. A line that is still in review when the purchase file needs funds can derail the plan.
A Worked Scenario, Using Ratios Only
Picture an investor with a paid-down primary home, a large brokerage account, and a strong credit profile. The investor wants a rental and does not want to sell appreciated holdings.
The purchase is at 75% LTV, so the line has to cover 25% down, plus closing costs, plus reserves if the lender wants them. The investor draws from a primary-residence line, which is eligible at a higher CLTV than a rental line. The new property’s rent clears about 1.2x against its own PITIA, which is a healthy file for most programs.
That 1.2x does not mean the investor has positive cash flow. DSCR compares rent to PITIA only. Repairs, vacancy, management, utilities, and capex all sit outside the calculation. And the line payment sits outside it too, because it is secured by a different property.
So the real test is a second one. Can the investor carry the line payment from other income if the new unit sits vacant? Can the investor carry it if the line’s variable pricing rises? A DSCR coverage ratio answers the first question about the property. It says nothing about the second question about the borrower. Strong files pass both tests.
The Structure of a Network HELOC
Lines placed through Lendmire’s network are standalone lines in first or second lien position. The details matter because they limit how the line behaves.
- Draw and repayment. Primary residences and second homes have two structures: a 3-year interest-only draw with a 17-year repayment, or a 5-year interest-only draw with a 25-year repayment. Investment lines run only the 5-year draw and 25-year repayment structure. Tennessee shortens both structures on primary residences.
- Drawn at closing. At least 75% of the line is drawn at closing. This is not a loose line that sits unused until needed.
- Pricing floats. Pricing floats through both the draw and repayment periods and never converts to fixed.
- Line size. Lines run from $25,000 to $750,000. Above $500,000 the line is primary-residence only. It requires 700 or better credit (720 on the longer-runway program, meaning the 5-year draw structure), caps at 75% CLTV, and needs a full appraisal.
- Property types. Single-family, 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 zoning are not.
The 75% drawn-at-closing rule changes the usual story about a revolving line. The investor starts paying on most of the line right away. That is fine if the line was sized for this one purchase. It is a poor fit if the plan was to borrow a little at a time.
For context on how the line behaves later, the CFPB explains that a line stops allowing new borrowing after the draw period and moves into repayment, and that falling behind can put the home at risk. Its HELOC booklet also explains that a credit limit is set as a percentage of the home’s value, less what is owed against it.
Where the General Rule Breaks
Several edge cases change the answer.
The property is held in an LLC. Network lines require fee simple or leasehold title held by the individual borrower or a revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. A rental already deeded to an LLC needs a vesting change, or the investor should look at a DSCR cash-out refinance instead. This is the sharpest structural difference from a DSCR loan, which can close in an entity name, subject to program terms.
The rental already has a large mortgage. With a 70% CLTV ceiling on investment lines, a heavily financed rental may leave almost no room. A line there may not be worth the effort.
The credit profile sits just under 700. An investment line has a 700 hard floor and no tier beneath it. A borrower at 690 can still qualify on a primary-residence line, with other limits, but not on the rental.
There are many financed properties. A borrower is limited to three lines in total. A borrower who owns more than 15 financed properties is not eligible.
The plan depends on a later refinance. One investor in a BiggerPockets discussion argues that expecting a cash-out refinance within a couple of years is unlikely to work unless significant equity is forced into the property. The point holds. A refinance depends on the property’s value, the seasoning, and the market at that time. About six months of seasoning is the common expectation for cash-out refinances in the network, and cash-out tops out around 75% LTV. Lendmire’s piece Best Investment Property HELOC Program to Pull Cash From a Rental Without Selling It covers that route in more detail. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
There is no true zero-down purchase. The line changes where the down payment comes from. It does not waive the requirement.
The line can be reduced or frozen. Lenders can lower a credit line if the property’s value falls, and the line must generally be repaid if the securing home is sold. An investor who counted on redrawing may find the line smaller than planned.
Tax treatment is unsettled. 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.
Four Funding Routes Compared
Selling holdings is not the only alternative to a line. Here is how the main paths compare in structure.
| Route | What you keep invested | Main risk |
|---|---|---|
| Home equity line | All holdings | Collateral property and variable payment |
| DSCR cash-out refinance | All holdings | New loan replaces the old mortgage |
| Borrowing against securities | Most holdings | Market drops can force sales |
| Selling holdings | Only what remains | Gives up future growth |
A DSCR cash-out refinance replaces your first mortgage and pays out a lump sum. A line leaves the first mortgage in place. That makes the line more attractive when your existing mortgage is one you want to keep. The cash-out is more attractive when you want a single fixed obligation instead of two.
Borrowing against securities appears here only as a structural comparison. Its terms depend on the lender and portfolio. The main flip point is how much you trust the market. If a downturn would shrink the collateral, you could be forced to sell at the worst moment. A property-secured line does not carry that specific risk, but it carries others.
Which Program Fits Which Investor?
The best program for your situation depends on several variables.
A line on the primary home tends to fit when:
- The investor has strong equity and a 720-or-better credit profile.
- The home is not in an LLC or an ineligible property type.
- The household can carry the payment without relying on the new rent.
A line on an existing rental tends to fit when:
- The investor wants to keep the personal residence out of the collateral.
- The rental has meaningful equity after its existing mortgage.
- Credit is 700 or higher.
- The needed line fits within the $500,000 maximum and the 70% CLTV ceiling.
A different route fits better when:
- The rental sits in an LLC and a vesting change is not practical.
- The existing mortgage is large and equity is thin.
- The investor expects to rely on the new rent to pay down the line.
Availability also matters. Lendmire’s HELOC programs are offered only in its 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 DSCR investor footprint of 41 markets, including Washington, D.C.
Key Terms Defined
HELOC: A revolving credit line secured by a property you own.
CLTV: Combined loan-to-value, which adds every loan on a property and divides by the property’s value.
Draw period: The stretch when you can borrow from the line, usually with interest-only payments.
Repayment period: The stretch after the draw period when the balance is paid down.
DSCR: Debt service coverage ratio, which compares a property’s rent to its PITIA (principal, interest, taxes, insurance, and any HOA dues).
PITIA: The full monthly housing obligation on a property.
Reserves: Liquid funds a lender may require you to hold after closing.
Vesting: How title is held, such as individually, in a revocable trust, or in an LLC.
Frequently Asked Questions
Can a HELOC cover the entire purchase price of a rental?
Usually not, and it is rarely the plan. A line is typically sized to cover a down payment and closing costs, while a DSCR purchase loan finances the rest. Most purchase files land at 75%-80% LTV, so the line supplies the remaining 20%-25% plus costs. Whether the purchase lender accepts a fully borrowed down payment depends on the program.
Does the HELOC payment count against the new rental’s DSCR?
Generally no. The DSCR reads the new property’s rent against that property’s own PITIA. The line payment sits on a different property. It still matters, though, because you have to pay it from other income if the rent falls short. A strong coverage ratio on the new unit does not replace a plan for carrying the line.
What is the maximum leverage on a line against a rental?
On Lendmire’s network, an investment-property line is capped at 70% CLTV, with a 700 minimum credit score and a maximum line of $500,000. Market surveys report higher figures, such as the 80% cited by Experian, but those describe the broader market rather than this network. Primary-residence lines can reach 90% CLTV, only at a 720-or-better credit profile.
Can I use the line if my rental is owned by an LLC?
Not directly. Network lines require title in an individual’s name or a revocable living trust. A property already deeded to an LLC needs a vesting change before it can secure a line, or the investor can consider a DSCR cash-out refinance instead, subject to program terms.
Is the interest rate on the line fixed?
No. Pricing floats through both the draw and the repayment period and never converts to fixed. That variable exposure is one reason to stress-test the payment before you commit.
