The Quick Read: One investment-property line can supply down payments for several purchases, but it never replaces the loans that buy them. The line is reviewed on you, your equity, and your debts. Each DSCR purchase loan is reviewed on that property’s rent against its own payment. Across the wholesale network Lendmire works with, the structure comes down to four points:
- An investment-property line tops out at 70% CLTV (combined loan-to-value, counting every lien) and $500,000 per line, with a 700 minimum credit score.
- At least 75% of the line is drawn at closing, and the cost floats for the life of the line.
- Title must sit with you personally or in a revocable living trust. An LLC cannot hold it.
- Each purchase closes as its own DSCR file, and that lender decides how it treats borrowed down-payment funds.
What an Investment Property HELOC Is (and Isn’t)
An investment-property HELOC is a revolving line of credit secured by a rental you already own. You borrow against equity, draw cash when you need it, and repay on a set schedule. The cash can go toward a down payment, closing costs, or rehab on your next deal. It does not buy the next property by 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.
That distinction matters when you are funding several deals. The line is one loan. Every purchase is a separate loan with its own review. Many investors picture a single approval that carries them through three or four acquisitions. It does not work that way.
On the network, an investment line runs from $25,000 to $500,000. A borrower can hold up to three lines. Combined exposure across lines caps at $2,000,000 on one wholesale program and $750,000 on the other. These are the two HELOC programs the network uses: one built for higher leverage, one with a longer interest-only runway. A borrower with more than 15 financed properties is not eligible. All figures are subject to lender guidelines and a full file review.
Availability is also narrower than the DSCR footprint. The line is offered in 16 full-service states, while Lendmire’s DSCR programs reach 41 markets, including Washington, D.C.
Market surveys paint a similar picture of how hard these lines are to get. NerdWallet reports that investment-property HELOCs typically want a 720 or higher credit score, cap at 80% LTV, and often sit below 70% at individual lenders, with six months or more of reserves. That is a market-wide statistic. On the network, the investment-property ceiling is 70% CLTV, and the minimum credit score is 700.
Which Property Secures the Line?
You have two choices of collateral. You can borrow against a rental you own, or against your primary residence. They behave differently, and the choice shapes the rest of the plan.
| Factor | Line on a rental | Line on your primary home |
|---|---|---|
| Max CLTV | 70% (investment) | Up to 90% at 720+ credit |
| Line size | $25,000–$500,000 | Up to $500,000 or more, by tier |
| Credit floor | 700 | Lower tiers exist |
| Your home at risk? | No | Yes |
| Appraisal | Usually automated | Automated, or full above $500,000 |
The primary-home line offers more leverage. It also puts the roof over your head behind every deal you fund. If one rental sits vacant for a season and the line payment keeps coming, that exposure is personal.
The rental-collateral line keeps your home out of it. The tradeoff is the lower 70% ceiling. Because the line caps at $500,000, it falls in the automated-valuation lane. It commonly closes with no traditional appraisal, though you can request one. For a deeper look at how the ceiling translates into usable cash, see Lendmire’s explainer on how much an investment property HELOC releases at different CLTV caps.
Some banks avoid the HELOC label on non-owner-occupied property. Investors on BiggerPockets advise asking for a line of credit secured by investment property instead. The wording changes the answer at some institutions.
How Underwriting Treats the Line, Step by Step
The HELOC is underwritten on the borrower. A DSCR purchase loan is underwritten on the property. Here is the order of events for a multi-deal owner.
1. The lender looks at collateral and title. The line must be held by you as an individual or by an inter vivos 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 before it can carry the line. Otherwise the usual alternative is a DSCR cash-out refinance, subject to program terms.
2. The lender checks the existing first mortgage. Many DSCR first mortgages carry an additional-lien covenant, a promise not to add liens without the first lender’s consent. Read your note before you apply. The network’s investment lines can sit in first or second position, but your existing note still controls what you may add.
3. Credit is reviewed. The score comes from a single-bureau model keyed to the primary wage earner. The report must be no more than 90 days old at closing, and no rescores are allowed. Housing payment history across every financed property is part of the review.
4. Debt-to-income (DTI) is tested. DTI means your monthly debt payments divided by your monthly income. The maximum is 50%. The payment is calculated on the interest-only payment at the full line amount, even if you plan to draw less.
5. Derogatory history is seasoned. A bankruptcy needs 4 years from discharge or dismissal. On investment files, a foreclosure needs 7 years. A deed-in-lieu, pre-foreclosure, or short sale needs 4.
6. The property is screened. Single-family homes, 2-4 units, PUDs, townhomes, and condominiums, including non-warrantable condos, are eligible. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not.
Notice what is missing. The line review does not ask whether the next property will rent well. That question belongs to the purchase loan.
How the Line Behaves After Closing
A HELOC works in two phases. The CFPB’s HELOC explainer describes the first as the draw period, when you can borrow up to your limit. Then the repayment period begins.
On the network, an investment line runs a 5-year interest-only draw followed by a 25-year fully amortizing repayment. Pricing floats across both phases and never converts to a fixed structure. The CFPB’s HELOC brochure notes that HELOC payments can change even when you draw nothing more. Expect that.
Two program details matter for multi-deal owners:
- At least 75% of the line is drawn at closing. You cannot park a large undrawn line and pay nothing until you buy. If you need a $400,000 line to cover several deals, you are carrying most of it from day one. Pick the line size to match what you will deploy soon.
- Later draws have a minimum. After closing, each draw is typically at least $1,000. That is not a constraint for down payments, but it shapes small top-ups.
The bigger risk comes at the end of the draw period. The payment steps up when interest-only becomes fully amortizing. Your rent does not step up with it. Plan for that step before you stack deals on top.
How One Line Funds Several Purchases
Funding several investments from one source works in a sequence. The line comes first. Each purchase follows as its own file.
Draw and season before you apply. Close the line and draw the cash before you submit the purchase loan. Then keep the money visible in your account. Purchase lenders want a paper trail from the line, to your account, to escrow. They want the HELOC closing documents, the draw confirmation, bank statements showing the cash landing, and a credit report showing the new liability. Some also want borrowed funds to sit for a stretch before use. Others do not. Ask before you draw.
Confirm the borrowed-funds rule first. Lenders in the network treat borrowed down-payment money differently. Some DSCR programs count it toward the down payment but not toward reserves. Others cap the borrowed share of the down payment. Drawing against a different property and documenting it is commonly accepted. Placing a second lien on the property you are buying at closing is the structure most lenders refuse.
Do not count line cash as reserves. DSCR purchase files commonly want around 6 months of PITIA in reserves. PITIA is principal, interest, taxes, insurance, and any association dues. Reserves vary by lender, leverage, loan size, and transaction type. Conservative rate-and-term files at modest leverage under $1,500,000 can see reserves waived. Larger loans typically step up to about 9 months. Never assume borrowed cash will count.
Size each purchase on its own. Most purchases land at 75%-80% LTV, which means 20%-25% down. Select high-leverage programs reach 85% LTV with roughly a 700 or better score. A larger down payment lowers the payment and can lift the DSCR. It never erases leverage caps, credit floors, reserve rules, or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.
A Worked Example: One Line, Two Purchases
Picture an owner with a free-and-clear rental and a primary home. They plan to buy two more rentals over the next stretch and want one funding source for both down payments. This example is a modeled scenario. It is not a market figure.
Assume each purchase is structured at 75% LTV on a standard rental purchase. Assume each clears roughly 1.25x on its own DSCR, meaning rent divided by the full monthly payment on that property’s loan. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
The line comes first. The owner closes a line on the free-and-clear rental, within the 70% CLTV investment ceiling, and draws enough for both 25% down payments plus closing costs. The line is drawn at least 75% at closing, so interest starts running immediately. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
Then the purchases close one at a time. Each lender reviews its own file, asks where the down payment came from, and sees the new line on the credit report. Each DSCR still reads roughly 1.25x, because the ratio compares rent to that property’s loan payment.
That number can mislead. The line payment is a second claim on the same rent. Add it to each property’s payment and combined coverage falls toward the low 1.0s, or below. If the line cost rises, it falls further.
Clearing 1.00 is also not the same as positive cash flow. DSCR compares rent to PITIA only. Repairs, vacancy, management, utilities, and capital expenses sit outside the calculation. An owner funding two deals this way carries a thin buffer. A single bad quarter on one rental can strain the rest.
Honestly, the discipline that separates owners who do this well is simple. They size each deal so rent covers the property loan and the share of the line payment attributable to that deal. They do it at a stressed rent, not the optimistic one.
In markets across the network, files like this often pass the coverage test and still run tight on personal cash flow. The stronger borrowers keep a separate cushion and plan an exit for the line, either a refinance or a sale, before they draw.
Where the General Rule Breaks
The step-by-step above covers most files. These edge cases cover the rest.
The phrase DSCR HELOC means two things. Some people use it for a first-lien DSCR cash-out refinance, which qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. Others mean a standalone line, which is reviewed on your DTI, not on rent. The two have different underwriting, so confirm which one you are being offered.
Subordination can trap a later refinance. If you hold a line in second position and later want to refinance the first mortgage, the line holder must agree to subordinate. It has no obligation to do so. Plan that before you draw.
LLC-held rentals. The HELOC programs cannot take LLC title. If your portfolio is held in LLCs, the line must come from a property you hold personally or in a revocable trust, or you move to a DSCR cash-out on the entity-held property, subject to program terms.
More than 15 financed properties. Past that count, you are not eligible. Owners with larger portfolios need a different tool.
Coverage near or below 1.00. On the DSCR side, 1.00 is where many select programs start. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Neither path changes the line’s own rules. The line is still reviewed on you.
Ineligible property types. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not eligible for the HELOC programs. DSCR purchase loans are also not offered on manufactured homes (single- or double-wide), log homes, or barndominiums.
Short-term rentals. A short-term rental purchase tops out at 75% LTV, expects a 640 or better score, and wants about 12 months of hosting history. 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. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.
Should You Use a Line, a Cash-Out, or Cash?
A line is one of three common ways to fund the next deal. Each is reviewed on a different lens.
| Option | Typical ceiling | Reviewed on |
|---|---|---|
| Investment HELOC | 70% CLTV, investment | Your credit, DTI, equity |
| DSCR cash-out refinance | About 75% LTV, standard rental | Rent against the payment |
| Cash savings | None | No review |
A DSCR cash-out refinance tops out around 75% LTV on standard rentals, while short-term-rental collateral is capped at 70% on a cash-out. It typically wants about 6 months of seasoning. It replaces your first lien, so your note’s lien covenant stops mattering. The cost is a new first mortgage.
The line leaves the first mortgage untouched. The cost is variable pricing and a second payment. Use the line when the existing first mortgage is worth keeping and the equity is large enough to matter.
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.
The line fits owners who want flexibility and have an exit planned for each draw. It fits poorly when rent is already thin, when the first note forbids added liens, or when the portfolio is held in LLCs.
Key Terms Defined
CLTV: Combined loan-to-value, which adds every lien on the property and divides by its value.
DSCR: Debt service coverage ratio, which divides a property’s monthly rent by its monthly housing payment.
PITIA: Principal, interest, taxes, insurance, and any association dues, the full monthly housing obligation.
Draw period: The stretch when you can borrow from the line. On the network’s investment lines, it is 5 years, interest-only.
Additional-lien covenant: A promise in your first mortgage not to add another lien without the first lender’s consent.
Subordination: An agreement by a junior lienholder to stay behind a new first mortgage after a refinance.
Seasoning: The waiting period a lender wants before it counts funds or ownership toward a new loan.
Frequently Asked Questions
Can I hold more than one investment-property line at once?
Yes, within limits. A borrower on the network can hold up to three lines. Combined exposure caps at $2,000,000 on one wholesale program and $750,000 on the other. Each line is secured by its own property, and each adds to your DTI and your housing-history review.
Can one line fund two purchases?
Yes, if the line is large enough and you draw before you apply for each purchase loan. Each purchase is its own DSCR file. The purchase lender decides whether borrowed funds count toward the down payment and whether they count toward reserves.
Will the line affect my DSCR purchase approval?
It can. The new liability appears on your credit report, and the lender will want the draw documented. The DSCR itself still compares that property’s rent to its own payment, so the ratio may not change. Reserves, borrowed-funds rules, and your credit profile are where the line shows up.
Is the HELOC rate fixed?
No. On the network, pricing floats through both the draw and repayment periods and never converts to fixed. The CFPB’s brochure also notes that HELOCs typically carry variable rates, so payments can change without new draws.
Is an investment-property HELOC available everywhere?
No. The programs are offered in 16 full-service states. Individual banks and credit unions set their own policies, which is why availability from other sources varies widely.
