The Quick Read: Buying a rental outright with a home equity line removes the purchase mortgage, so no lender runs a coverage test at closing, but the rental must still produce enough rent to carry the line’s interest-only payment, taxes, insurance, repairs, and vacancy from day one, and then pass a real rent-to-PITIA test if you refinance to repay the line.
- The home equity line (HELOC) tests you personally. A DSCR loan tests the property. A full-cash purchase uses the first test at closing and the second only at the exit.
- The line’s payment never appears in a DSCR ratio, but it hits your bank account every month.
- The payment steps up when the interest-only draw period ends and principal begins.
- The loan size you choose at the refinance decides whether the exit works.
- Clearing 1.00x on a DSCR calculation is not the same as positive cash flow.
Key Terms Defined
HELOC: A revolving line of credit secured by property you already own, with a draw period followed by a repayment period.
Draw period: The stretch when you can borrow and typically pay interest only.
Repayment period: The stretch after the draw ends, when the balance amortizes and the payment rises.
PITIA: Principal, interest, taxes, insurance, and association dues on a loan.
DSCR: The monthly rent divided by the PITIA of the loan being underwritten.
Break-even rent: The gross rent at which every monthly cost, including vacancy and reserves, is covered and nothing is left over.
CLTV: Combined loan-to-value, which adds every lien on a property together and divides by its value.
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 Actually Changes When There Is No Purchase Mortgage?
The rental’s debt service line changes owners. With a mortgage purchase, the rental carries a first lien and the lender tests the property. With a full-cash HELOC purchase, the rental carries no lien and the line sits on a different property. Your personal credit and income carry the test.
| Factor | Mortgage purchase | Full-cash HELOC purchase |
|---|---|---|
| Lien on the rental | Purchase mortgage | None |
| Who is tested at closing | The property’s rent | The borrower personally |
| DSCR test at closing | Yes | No |
| Where the shortfall lands | Rental cash flow | Household income |
| Collateral at risk | The rental | The property securing the line |
That last row is the one investors skip. If the rent falls short of the line’s payment, the gap comes out of your own pocket. If the gap persists, the property at risk is the one securing the line, which is often your home.
Across the wholesale network, DSCR files treat rent against the debt on the subject property only. A line sitting on some other property never shows up in that ratio. The ratio can look clean while the household is quietly subsidizing the rental.
How Underwriting Treats a Full-Cash HELOC Purchase, Step by Step
Two underwriting events can happen on one rental, months or years apart. The first tests you. The second tests the rent.
1. The line is underwritten on the borrower. The lender looks at credit, debts, and the property securing the line. On an investment property, the line caps at $500,000 total and 70% CLTV, with a 700 minimum credit score, subject to lender guidelines. Lines on a primary residence follow a separate table.
2. Debt-to-income applies. The maximum is 50%, and the lender reviews your file on the interest-only payment calculated on the maximum draw, not on what you actually borrow. A big line you never fully use still counts against you.
3. Valuation is usually automated. Because an investment line tops out at $500,000, it commonly runs on an automated valuation with no traditional appraisal, though a borrower may request a full appraisal.
4. Most of the line is drawn at closing. At least 75% of the line is funded when the line opens. It is not a standby fund. Plan for the payment on most of the balance immediately.
5. The purchase closes as cash. The seller sees a cash buyer. Keep the draw record, the wire, and the settlement statement together, because a later refinance reviewer will want the trail.
6. The rental stabilizes. Rent has to cover the line’s payment, taxes, insurance, and operating costs. No lender checks this. You do.
7. The exit gets underwritten as a DSCR loan. If you refinance to repay the line, the lender compares rent to the new loan’s full PITIA, subject to lender guidelines and credit approval. The documents usually include the lease or a market rent schedule, the appraisal’s rent form (Form 1007 for a single-family rental, Form 1025 for a small multi-unit property), the settlement statement from the cash purchase, and the HELOC draw records.

What Does the Draw Period Do to the Rent You Need?
The interest-only draw period makes the required rent look low, and it does not stay that way. The investment line runs a 5-year interest-only draw followed by a 25-year fully amortizing repayment, and pricing floats across both stages and never converts to fixed. A CFPB brochure on home equity lines says some plans allow interest-only payments in the draw period, so nothing goes toward principal. It also says payments on a variable-rate plan can change even if you borrow nothing more, and that when repayment begins the lender may set a schedule to repay the full amount or the whole balance may come due.
Market-wide, one consumer-education page describes a typical 10-year draw and 20-year repayment for home equity lines generally. The network’s investment line is different: a 5-year draw and a 25-year repayment, with the structure fixed by the program.
The required-rent formula, in words:
Break-even gross rent = (line payment + taxes + insurance + dues + operating costs + reserve contribution) ÷ (1 − vacancy share).
Here is a worked example using modeled assumptions, not market data. Everything is expressed as a share of gross rent.
- Line interest payment: 55% of rent.
- Taxes, insurance, and dues: 20% of rent.
- Repairs, management, and utilities: 15% of rent.
- Vacancy allowance: 5% of rent.
- Total: 95% of rent, leaving a thin margin of about 5%.
Now stress it. If pricing on the line floats up and the interest payment grows by a fifth, it becomes about 66% of rent and the total reaches roughly 106%. The rental is now short. If the repayment period starts and the line’s payment rises to about 85% of rent, the total is around 125%. The same property that looked comfortable in the draw period needs about a quarter more rent, or a paydown, to break even.
Run the formula at the repayment-period payment, not the draw payment. A rental still stabilizing when the draw ends is the most exposed.
Coverage Ratio Is Not Cash Flow
DSCR compares rent to PITIA and nothing else. Repairs, vacancy, management, utilities, and capital expenses sit outside the calculation. A rental can clear 1.00x and still lose money every month.
Consider two exit scenarios, both modeled. In the first, the new DSCR loan’s PITIA equals 80% of rent, which is a 1.25x coverage ratio. After operating costs of around 15% and a 5% vacancy allowance, the margin is essentially zero, so there is no cushion left for a surprise repair or an extended vacancy. In the second, PITIA equals 100% of rent, which is 1.00x. Many select programs start at 1.00x, and a separate select-lender path takes coverage below 1.00x with leverage and terms adjusted. At 1.00x, though, operating costs and vacancy push cash flow negative even though the ratio looks acceptable.
The HELOC adds a second layer. A DSCR ratio at refinance looks only at the new loan. While the line is outstanding, the personal side matters, because a drawn line counts in your debt-to-income on any later personal application. Reserves matter too. On the DSCR side, reserves vary by lender, leverage, loan size, and transaction type, commonly around 6 months of PITIA, with conservative rate-term files at modest leverage sometimes seeing them waived and larger loans stepping up to about 9 months. Unused line availability generally does not stand in for reserves, so assume reserves must be liquid.
For the other side of this analysis, see Lendmire’s piece How a HELOC Lender Counts the Cash Flow a Rental Must Cover.
Structures and Variations That Exist
The basic idea has several versions, and each changes the cash-flow math.
Line on your primary home. The rental stays clear of liens and the home carries the risk. This is the most common setup. A line on the home is underwritten on the primary-residence table, not the investment table.
Line on another rental. The investment table applies: 70% CLTV, $500,000 cap, 700 minimum credit. A later refinance of the new rental pays down that line.
First or second lien position. The line can be a standalone first or second lien. If a first mortgage sits ahead of it and you later refinance that mortgage, the line’s lender has to agree to stay in second position. It is not obligated to.
Refinance exit. After purchase, most files that exit to a DSCR loan land at a cash-out refinance, which tops out around 75% LTV across most of the network, with about 6 months of seasoning as the common expectation. For short-term rentals, cash-out is limited to 70%, and the file needs about 12 months of hosting history. Sizing the new loan to just repay the line keeps PITIA lower and coverage stronger. Taking extra cash out raises PITIA and shrinks the ratio.
Term structures at the exit. The spine is the 30-year fixed. Extended terms such as 40-year and interest-only periods are available through select lenders, and ARM structures exist. Interest-only DSCR loans may measure rent against interest, taxes, insurance, and dues instead of full PITIA, which lifts the ratio but does not reduce principal.
A delayed-financing-style exit. Some select lenders shorten the usual seasoning wait on a true cash purchase and size the new loan near documented cost. Coverage, appraisal, and reserves still apply. Whether a purchase funded by a line qualifies as cash is lender-specific. Ask the specific program before relying on it.
Where the Rule Breaks
The general rule is that no mortgage means no coverage test at closing. Several edge cases bend it.
- Lenders disagree on whether HELOC money is cash. A drawn line is borrowed money. Some lenders treat the purchase as cash for a delayed-financing-style path and some do not. There is no universal answer, so this belongs on your first call with the lender, before the purchase.
- Hard-money and bridge purchases are different. They are financed from day one and generally do not fit a cash-purchase exception.
- The line can be frozen or cut. A lender may reduce or suspend a line. If you plan to draw more later, do not count on funds you have not already pulled.
- A line cannot be held by an LLC. On this network, a home equity line requires title held by an individual or a revocable living trust. LLCs, corporations, partnerships, and irrevocable or land trusts cannot hold title. A property already deeded to an LLC needs a vesting change or a DSCR cash-out instead. For DSCR loans made to LLC-titled borrowers, eligibility is subject to program terms.
- The line size has a ceiling. An investment line caps at $500,000 total, so a purchase above that needs additional cash or a different structure.
- Some property types are not eligible. Manufactured homes, log homes, and barndominiums are not offered on DSCR loans in the network, and manufactured homes, co-ops, condotels, and commercial or mixed-use property are not eligible for the line.
- Availability is narrower than DSCR. The home equity line is brokered in Lendmire’s 16 full-service states, while the DSCR program covers 41 markets, including Washington, D.C.
- Exposure limits apply. A borrower is limited to three lines, and an owner with more than 15 financed properties is not eligible.
What the Decision Looks Like in Practice
The choice is between three structures, and the right one depends on which constraint binds first.
| Structure | Strongest when | Main risk |
|---|---|---|
| Full-cash HELOC purchase | Equity is large, a cash offer wins | Variable payment, no property-level test |
| HELOC for the down payment, DSCR loan for the rest | Rent covers the debt but cash is short | Two payments on one deal |
| DSCR purchase with cash saved | Cash is on hand | Ties up liquidity |
On a standard DSCR purchase, most files land at 75% to 80% LTV, with select high-leverage programs reaching 85% LTV at roughly a 700 score. A larger down payment lowers the payment and can lift the ratio, but it never erases leverage caps, credit floors, reserve rules, or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage. For a side-by-side look, see Lendmire’s piece HELOC as Down Payment vs Full Cash Purchase of a Rental.
A cash offer often negotiates a better price. The cost is carrying a floating-price balance until the exit. A practical test is to model the rental at the repayment-period payment and the stressed payment. If the property still breaks even, the structure is sound. If it needs a rent increase to survive, the structure is a bet on the market.
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.
Before drawing, run these numbers in order:
1. Break-even rent at the draw-period payment.
2. Break-even rent at a stressed payment.
3. Break-even rent at the repayment-period payment.
4. Projected DSCR on the refinance that repays the line.
5. Liquid reserves after the draw.
Frequently Asked Questions
Does the HELOC payment count in the DSCR ratio?
No. The ratio compares rent to the PITIA of the loan being underwritten. A line sitting on another property never enters it. The payment still reduces your real monthly cash flow, and a drawn line counts against your debt-to-income on later personal applications.
What rent does the rental need to break even?
The rent that covers the line’s payment, taxes, insurance, dues, operating costs, and a reserve contribution, divided by the share of rent you actually collect after vacancy. Run it at the draw-period payment and again at the repayment-period payment, because the second is materially higher.
What happens when the draw period ends?
The balance begins to amortize and the payment steps up. On the network’s investment line, the 5-year interest-only draw gives way to a 25-year fully amortizing repayment. Pricing floats throughout and never converts to fixed.
Can I refinance the rental to pay off the line?
Often yes, through a DSCR cash-out refinance, subject to lender guidelines, seasoning, and property review. Most of the network tops out around 75% LTV on standard rentals. The new loan has to repay the line and still clear the lender’s coverage test.
Can an LLC hold the property securing the line?
No. On this network, title for a home equity line must be held by an individual or a revocable living trust, so a property already deeded to an LLC needs a vesting change or a DSCR cash-out instead.
