The Quick Read: A rental HELOC is a revolving line secured by a property you already own, and it supports a cash offer only after you draw it, because drawn funds sit in your account as usable money while an undrawn line is only borrowing capacity. On the wholesale network Lendmire works with, an investment-property line tops out at 70% CLTV and $500,000, so it fits a down payment or a modest purchase better than a large one. Everything below is subject to lender guidelines and full file review.
- The line is judged on you (credit, debt-to-income, equity), not on the new property’s rent.
- It must be secured by something you already own: a rental, or your primary home.
- An investment line carries a 700 minimum credit score, and a higher score buys eligibility, not extra leverage.
- A line only supplies cash. A separate loan, often a DSCR loan, can finance the rest or replace the cash afterward.
- A line payment competes with the same rent your next DSCR loan counts, so coverage above 1.00 does not mean positive cash flow.
What Counts as a Cash Offer When the Money Is Borrowed?
A cash offer means the seller sees no financing contingency. A drawn HELOC meets that test because the money is already in your account. An undrawn line does not, and some sellers accept it anyway while others will not.
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.
Sellers care about one thing: can you close without a lender’s approval standing between you and the keys? Home equity alone does not answer that. Equity becomes proof of funds only after you turn it into a drawn line or a closed cash-out refinance.
Infosys BPM draws the same line between documents: a proof-of-funds letter confirms cash you already hold, while a preapproval letter only estimates what a lender would lend. A HELOC approval letter belongs in the second category until you draw.
Proof of funds usually means a recent bank or brokerage statement, or a letter on institution letterhead. The name should match the buyer on the offer, and the amount should cover price, fees, and closing costs. One investor on Bogleheads describes a bank or brokerage statement as the usual proof and notes the letter need not say whether the money is cash or a line. That is one person’s experience, so treat practice as seller-specific and contract-specific.
The honest play is to say which kind of funds you have. A buyer who claims cash and then needs weeks of paperwork loses the seller’s trust faster than a buyer who discloses a drawn line up front.
Which Property Backs the Line?
You can secure the line with an existing rental or with your primary home. The rental route is more restricted: an investment line caps at 70% CLTV and $500,000. A primary-home line reaches higher leverage, but only with a stronger credit profile.
CLTV means combined loan-to-value: every loan on the property, added together, divided by its value. You cannot open a line against a property you have not bought yet, so the collateral is always something already on your balance sheet.
| Factor | Line on existing rental | Line on primary home |
|---|---|---|
| Max CLTV | 70% | Up to 90% at 720+ credit |
| Line size | $25,000 to $500,000 | $25,000 to $750,000 |
| Credit floor | 700 | 600 program floor |
| Valuation | Usually no full appraisal | Full appraisal above $500,000 |
| Draw structure | 5-year draw, 25-year repayment | Two structures available |
Investment credit has two tiers, 700 and 720, and both reach 70% CLTV. That is why a higher score does not buy more leverage on a rental line. A primary-home line above $500,000 is the only place the larger line sizes exist, and it requires a full appraisal and tighter terms.
NerdWallet notes that investment-property lines generally carry lower maximum loan-to-value, fewer lenders offer them, and pricing and fees tend to run higher. That matches what a broker sees: large retail lenders often decline non-owner-occupied lines, so access depends on knowing which lenders in a network will take them.
Using the primary home as collateral has a cost you should weigh honestly. The roof over your head now backs the down payment on an investment.
How Underwriting Treats the Line, Step by Step
The lender underwrites you, not the property you plan to buy. Steps run in a fixed order: pick collateral, size the line, review your credit and debt, value the property, close and draw, then document the funds for the seller.
1. Pick the collateral. Decide whether the line sits on a rental or on your primary home. The line can sit in first or second lien position, meaning it can be the only loan on the property or sit behind an existing mortgage.
2. Size the line. The lender takes the property’s value, applies the CLTV ceiling, and subtracts every existing loan. What remains is the maximum line, capped at $500,000 on an investment property.
3. Underwrite the borrower. Expect a 700 minimum credit score on an investment line. Maximum debt-to-income is 50%, and the lender reviews your file on the interest-only payment calculated on the maximum draw, not the amount you actually plan to use. Documents on a rental line commonly include filed returns, bank statements, and a mortgage statement for each property you own.
4. Value the property. Because an investment line cannot exceed $500,000, it ordinarily runs on an automated valuation with no traditional appraisal. A borrower can still request a full appraisal.
5. Close and draw. At least 75% of the line is drawn at closing, and pricing floats through both the draw and repayment periods without converting to fixed. Idle drawn money still costs interest.
6. Document the funds. The drawn money lands in your account. A statement or letter then shows it to the seller, agent, and title company.
7. Buy, then optionally refinance. After a cash purchase, many investors place long-term financing on the property to repay the line and recycle the cash.
Apply before you offer, not after. A buyer who still has to apply for a line when the offer goes in has only a plan, not cash, and sellers can tell the difference.
Sizing the Line: Where the CLTV Math Bites
The 70% CLTV ceiling means the line can only reach the equity above your existing loans, so a heavily financed rental produces a small line. Run the numbers in percentages of value, and the limit becomes obvious.
Say you own a rental with a first mortgage equal to 40% of its value. The 70% ceiling leaves room for a line worth up to 30% of that value, still subject to the $500,000 cap. If the same rental carries a first mortgage at 55% of value, only 15% is left.
Now compare that to what you want to buy. If you aim to pay the full price in cash, you need a line equal to 100% of the new property’s price. A rental with 30% usable equity would have to be worth more than three times the property you want to buy. For most investors, the line covers the down payment, not the whole purchase.
That is why the most common structure pairs the two loans. The line supplies the down payment, and a DSCR purchase loan finances the balance. The seller still sees a clean offer with no financing contingency if the line is drawn, but you hold stacked debt.
Structures and Variations Worth Knowing
Three structures matter: a line-funded down payment with a DSCR purchase loan, a fully line-funded purchase followed by a DSCR cash-out refinance, and a cash-out refinance on the rental instead of a line. Each has different leverage, documentation, and carrying cost.
Line plus DSCR purchase loan. Across the wholesale network, most DSCR purchase files land at 75% to 80% LTV on a purchase, which means 20% to 25% down. Select high-leverage programs reach 85% LTV on a purchase (15% down) with roughly a 700-plus score. The DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. The complete DSCR loans guide walks through that math.
Fully line-funded purchase, then refinance. If the line covers the whole price, a later DSCR cash-out refinance can pay it down. Cash-out tops out around 75% LTV on a standard rental across most of the network, and about 6 months of seasoning is the common expectation. For short-term-rental collateral the cash-out ceiling is 70%. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
Cash-out refinance instead of a line. A cash-out refinance replaces the first mortgage and is judged mainly on rent. A line adds a loan beside the first mortgage and is judged on you. Lendmire’s piece Is a Cash-Out Refinance the Usual Way Investors Fund the Next Rental? covers that route, and the one on investment property HELOC for investors buying their next rental goes deeper on the line itself.
On coverage, 1.00 is where many select DSCR 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. Credit works similarly: a 620 floor exists in parts of the network, most programs want around 660, and 700-plus unlocks the strongest tiers. Reserves vary by lender, leverage, loan size, and transaction type, and commonly sit around 6 months of PITIA, meaning principal, interest, taxes, insurance, and association dues.
One practical point from files like these: the DSCR loan counts only the new property’s own payment against its own rent. It never sees the line payment. So a deal can clear 1.00 on paper while the real monthly picture, with the line payment added, runs negative.
Where the General Rule Breaks
The rule that a line turns equity into cash fails in five situations: title held in an LLC, lenders that decline rentals, borrowers near the exposure caps, ineligible property types, and states outside the HELOC footprint.
LLC title. An LLC cannot hold title on these lines. Title must be personal or in a revocable living trust. Corporations, partnerships, and irrevocable, blind, or land trusts are also out. If your rental already sits in an LLC, you need a vesting change, or you use a DSCR cash-out refinance instead, since DSCR loans can be vested in an LLC subject to lender program eligibility. Name mismatch also hurts proof of funds: a personal offer funded from a business account raises questions at the title company.
Lender policy. Many banks decline non-owner-occupied lines, and some cap how many rentals you may own. Fewer lenders offer the product, so a no from one bank says little about your file.
Exposure caps. A borrower is limited to three lines. Combined exposure caps at $2,000,000 on the higher-leverage program and $750,000 on the other. A borrower with more than 15 financed properties is not eligible. A portfolio investor can hit that wall quickly in count, even with plenty of equity.
Property types. Eligible collateral includes single-family homes, 2-4 units, PUDs, townhomes, and condominiums, including non-warrantable ones. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agriculturally zoned properties are not offered. The same goes for barndominiums on the DSCR side.
Availability. Lines are arranged only in Lendmire’s 16 full-service states, which is narrower than its DSCR footprint of 41 markets, including Washington, D.C. An investor in a DSCR-only market may need a different route to the down payment.
Credit history can also break the rule. A bankruptcy needs 4 years of seasoning from discharge or dismissal, and a foreclosure on an investment file follows a 7-year path, with a deed-in-lieu, pre-foreclosure, or short sale at 4.
Cash Offer or Financed Offer?
A cash offer earns its premium when the seller values certainty and your cost of carrying borrowed money stays below what certainty wins you. When the seller weighs price above all else, a financed offer may be the better use of equity.
| Situation | Line-funded cash offer | Financed offer |
|---|---|---|
| Seller wants certainty | Strong fit | Weaker |
| Property needs repairs lenders dislike | Strong fit | May stall |
| Thin reserves | Risky | Safer |
| Plan to refinance after | Works, with seasoning | Not needed |
| Seller is price-driven | Less useful | Equal or better |
Thinking out loud: the strongest case for a line is a property that a standard lender will not touch as-is, because a cash buyer can acquire it and then finance after repairs. The weakest case is a clean listing where a normal DSCR loan with 20% to 25% down would have worked, and the line only adds a second payment. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.
The break-even test is simple. Estimate what the cash offer might win you, whether a lower price or a seller who picks you over a higher bid, and compare it to what the line costs while you hold it. If the line sits drawn for a long stretch because the refinance is delayed, the carrying cost can erase the discount.
The Stress Test: What Goes Wrong
Stacked debt turns small problems into expensive ones. The new property’s loan and the line must both be carried at once, and the line’s pricing floats. Three scenarios deserve a written plan before you offer.
- Vacancy runs long. The line payment comes out of your pocket, not out of the rent, if the unit sits empty.
- Repairs run over. A longer rehab extends the time the drawn funds sit idle at full interest.
- The refinance does not land. If appraisal, seasoning, or credit blocks the takeout loan, you carry both debts longer than planned. Since the payment is interest-only during the draw and fully amortizing afterward, the monthly obligation steps up when repayment begins.
Do not draw extra funds as a cushion unless you need them. At least 75% of the line is drawn at closing, so size the line to the deal, not the maximum. An investor with thin reserves should treat the closing draw as a real cash-flow commitment.
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, since IRS Publication 936 ties home-mortgage interest treatment to how borrowed funds are used.

Frequently Asked Questions
Is a HELOC the same as cash to a seller?
A drawn HELOC functions as cash because the money is in your account and no lender approval stands between you and closing. An undrawn line is capacity, not funds, and sellers treat it differently. Tell the seller which one you have.
Can I use a HELOC on a property I have not bought yet?
No. A line must be secured by a property you already own, so it attaches to a rental or your primary home. After you buy the new property, it can become collateral for a later line, subject to the same eligibility rules.
How much can I borrow against a rental?
An investment-property line reaches up to 70% CLTV and a $500,000 maximum on the network Lendmire works with, with a 700 minimum credit score. The amount depends on your existing loans, since the line only reaches equity above them. Every file is underwritten individually.
Can my LLC take out the line?
No. LLCs cannot hold title on these lines, so the rental must be in your personal name or a revocable living trust. DSCR loans have different rules and can be vested in an LLC, subject to lender program eligibility.
Will the line help me qualify for the DSCR loan on the new property?
Not directly. The DSCR loan counts the property’s rent against its own payment and does not see the line payment. The line helps you fund the down payment, but you still have to carry both loans from the same rent and your own reserves.
