The Quick Read: A home equity line on your primary residence can supply the cash for the down payment on a first rental, but it never buys the property by itself, because a separate loan, usually a DSCR loan that qualifies primarily on the property’s rental income covering its payment, finances the purchase, and you carry both debts at once.
- Two loans, two tests. The line is judged on you and your home. The DSCR loan is judged on the rental. Both are subject to lender guidelines.
- Leverage stacks. On a primary residence, lines in Lendmire’s network reach 90% CLTV only at a 720-or-better credit profile. On a DSCR purchase, most files land at 75%-80% LTV.
- The line is mostly drawn at closing. At least 75% of it is drawn when the line closes, so size it to the down payment, not to your ambitions.
- Rent covers the DSCR loan, not the line. The HELOC payment sits outside the ratio but still comes out of your pocket.
- Borrowed down payments get their own review. Each DSCR lender decides whether borrowed funds count, and how much of the down payment they may be.
How Does a HELOC Fit Into a First Rental Purchase?
A HELOC is a revolving credit line secured by a home you already own. You borrow against that home’s equity, move the cash to your own account, and use it as the down payment on the rental. The rental then gets its own mortgage.
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.
The two loans run on opposite logic. The line is personal credit: your score, your income, your debts, and the equity left in your house. The DSCR loan is property-based. It asks whether the rent covers the monthly obligation on the new place.
That split is why this strategy appeals to a first-time landlord. You may have plenty of equity and little spare cash. A HELOC turns one into the other without touching your first mortgage.
It also means one rent check is now supporting two obligations. Everything else here follows from that fact. If you want the full background on the rental-loan side, Lendmire’s complete DSCR loans guide covers it end to end.
Key Terms Defined
HELOC: A home equity line of credit. You borrow against your home’s equity as needed, up to a set limit.
CLTV (combined loan-to-value): Your first mortgage plus the new line, divided by the home’s value. It measures total leverage on one property.
LTV (loan-to-value): The loan divided by the property’s value. On a purchase, a 75% LTV means a 25% down payment. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
DSCR (debt service coverage ratio): Monthly rent divided by the monthly housing obligation. A 1.00 means rent equals the payment.
PITIA: Principal, interest, taxes, insurance, and any association dues. It is the full monthly obligation the DSCR measures against.
Draw period: The stretch when you can borrow from the line, often paying interest only.
Repayment period: The stretch after the draw ends, when you pay the balance down.
Reserves: Cash left after closing, usually counted in months of PITIA.
How Do Lenders Treat Each Loan, Step by Step?
The line and the rental loan are two separate files. Different lenders review them under different rules. Here is the order in which things actually happen.
1. Open the line first. You cannot borrow against a rental you have not bought. So the home you live in is the collateral. The lender reviews your credit, the equity left after your first mortgage, and your debt-to-income ratio. Future rent from the rental does not qualify you for a primary-home line.
2. Draw the cash and keep it traceable. Move the money into your own account. Keep the statements. The purchase lender will want to trace the down payment back to the line.
3. The DSCR lender decides if borrowed funds count. This is the step people skip. Some lenders in the network accept a documented HELOC draw as down payment. Some limit how much of the down payment can be borrowed. Ask before you go under contract, not after.
4. Rent gets evaluated on the new property. The lender uses market rent, typically from an appraisal rent schedule. The common appraisal forms are the 1007 for a single unit and the 1025 for two to four units. That rent is compared with the new loan’s PITIA.
5. The ratio ignores your line. The HELOC payment is generally outside the DSCR. It still reduces your real monthly margin.
6. Reserves are a separate test. The down payment and the reserves are two different piles of cash. Reserves commonly run around 6 months of PITIA, and they vary by lender, leverage, loan size, and transaction type. One draw rarely covers both without planning.
Notice what is missing: your pay stubs and your employer. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. Your line, though, does look at your personal profile. Both halves of the deal get reviewed.
How Much Can You Draw?
On a primary residence, lines in Lendmire’s network reach as high as 90% CLTV, and that top figure exists only at a 720-or-better credit profile. Line sizes run from $25,000 to $750,000. Lines at or below $500,000 ordinarily use an automated valuation instead of a full appraisal.
Lendmire brokers these lines through select wholesale partners and is never the lender. Every figure below is subject to lender guidelines and full file review.
| Line type | Max CLTV | Credit | Size |
|---|---|---|---|
| Primary residence, top tier | 90% | 720+ | Up to $500,000 |
| Primary residence, above $500,000 | 75% | 700+ (720 on the longer-runway program) | Up to $750,000 |
| Investment property | 70% | 700 minimum | Up to $500,000 |
The longer-runway program is the wholesale program built around the longer interest-only draw. Primary-residence lines overall have a 600 credit floor. But the higher tiers need the scores in the table.
Percentages matter more than dollars here, so run the math on percentages. Say your first mortgage is 50% of your home’s value and your credit sits at 720 or better. The 90% CLTV ceiling leaves up to 40% of the home’s value as theoretical room. In practice, the line size cap, your debt ratio, and the property itself narrow that.
Now stack the rental on top. A DSCR purchase at 75% LTV means you bring 25% down. At 80% LTV, you bring 20%. Select programs reach 85% LTV with a score around 700 or better. Fund all of that from the line and you have effectively financed the rental at 100%, with your home carrying part of it. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
Here is a modeled picture, not a market fact. Suppose a rental clears 1.25x on the DSCR loan alone. Add the line’s interest-only payment to the monthly obligation, and your all-in coverage can slip toward 1.00x or below. The DSCR number looks fine while your cash position gets tight.
What Structures Exist?
Two draw structures exist on primary-residence lines. One is a 3-year interest-only draw followed by a 17-year fully amortizing repayment. The other is a 5-year draw followed by a 25-year repayment. Investment lines run the 5-year/25-year structure only.
At least 75% of the line is drawn at closing. Pricing floats during both the draw and the repayment period and never converts to a fixed structure. After closing, you can draw the rest in later pulls.
That 75% rule has a practical effect. Open a line far bigger than your down payment and you start paying interest on money you do not need. Size it to the job.
The CFPB’s HELOC brochure describes the general pattern. A draw period comes first, during which some plans allow interest-only payments. A repayment period follows. Pricing is built from an index plus a margin, so payments can change even if you do not draw more. Some plans can leave a balloon payment at the end.
What About a Line on the Rental Itself?
You can also borrow against an investment property, but a first-time landlord rarely has equity in one yet. A new rental bought at typical DSCR down payments starts with high combined leverage. NerdWallet’s explainer notes that lines on rentals tend to come with a smaller lender pool, lower limits, and higher costs, because lenders see more default risk.
In Lendmire’s network, an investment-property line tops out at 70% CLTV and $500,000, with a 700 credit minimum. Credit above 700 does not buy more leverage there.

Your Options Side by Side
| Option | Touches your first mortgage? | Main tradeoff |
|---|---|---|
| HELOC on your home | No | Home becomes collateral |
| Cash-out refinance of your home | Yes, replaces it | Resets your first loan |
| Line on the rental | No | Needs equity you may not have |
| Save longer | No | Slower; cash stays safe |
A cash-out refinance on your own home is the main alternative. It swaps your existing first mortgage for a bigger one. If your first mortgage is one you want to keep, the line is often the cleaner tool. Saving longer has no collateral risk. It just costs time.
Where the General Rule Breaks
The rule of thumb says: open a line, draw the cash, buy the rental. Here are the places that rule bends.
Payment shock at the end of the draw. Interest-only payments feel light. When the draw ends and the balance starts amortizing, the payment can jump. On a 5-year draw that jump lands around year six, right when your rental may still be stabilizing.
The lender won’t count borrowed funds. Treat this as a pre-contract question. If your chosen DSCR lender limits borrowed down payments, you may need to put some of your own savings in, or pick another lender in the network.
Your own home is the wrong property type. The home you borrow against must be eligible. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not offered on the line. Single-family, 2-4 units, PUDs, townhomes, and condominiums (including non-warrantable) are eligible, subject to program terms. And the DSCR side has its own list: DSCR loans on manufactured homes (single- and double-wide), log homes, and barndominiums are not offered in the network.
Title is held in an LLC. The line’s collateral must be held by you personally or by a revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. If your home already sits in an LLC, you need a vesting change first. The rental itself can sometimes sit in an LLC on the DSCR side, subject to lender program eligibility, but the line stays a personal debt either way.
Your debt ratio is high. The line allows a maximum 50% debt-to-income ratio. It drops to 45% for credit profiles from 600 to 679, and anything above 45% needs a 680 minimum. The lender reviews your file on the interest-only payment calculated on the maximum draw, not the amount you plan to use.
You are near an exposure cap. A borrower is limited to three lines. Combined exposure caps at $2,000,000 on the higher-leverage program and $750,000 on the longer-runway program. Owning more than 15 financed properties makes you ineligible. A first-time landlord is nowhere near that, but it matters later.
The rental’s rent is thin. A rent check that covers 1.00x is where many select programs start, not a universal rule. A separate select-lender path takes coverage below 1.00 with leverage and terms adjusted. No-ratio structures exist only through select lenders, generally for borrowers who already own a primary residence. That describes you. Expect lower leverage and different terms on either path, and keep in mind that clearing the ratio is not the same as positive cash flow. Repairs, vacancy, management, utilities, and capital expenses all sit outside the calculation.
You want a short-term rental. The leverage rules shift. A short-term-rental purchase tops out at 75% LTV and expects a 640+ score and roughly 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.
You want to retire the line fast with a refinance. Many DSCR loans carry a prepayment penalty. That can make a quick cash-out refinance expensive. Cash-out refinances in the network top out around 75% LTV, and about 6 months of seasoning is the common expectation. Seasoning is the waiting period a lender wants after you buy a property. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.
How a Practitioner Sees These Files
Here is the pattern that repeats. The strongest files draw the line well before the contract date, park the money in a personal account, and hold the statements in one folder. The messiest files draw the cash a day before closing and then scramble to explain a lump-sum deposit.
The other pattern is the borrower who sizes the line to the down payment and nothing else. That leaves no cash for reserves, repairs, or a vacant month. The DSCR loan can look fine on paper. The owner’s checking account tells a different story.
Who Should Do This, and Who Should Skip It?
This one is a genuine judgment call. The line makes sense if you have meaningful equity, a stable income, and a rental whose rent comfortably exceeds its full obligation. It makes sense if you would rather keep a good first mortgage intact. It also fits when you hold reserves outside the draw.
Skip it if the rental only works when everything goes right. Skip it if a single vacant stretch would make both payments hard to meet. And skip it if you are borrowing close to your home’s limit just to reach the minimum down payment.
Here is a simple test. Could you make both payments for several months with the rental empty? If the answer is no, wait or buy smaller. Your house is the collateral, and that is not a spot you want to be in with no margin.
A quick checklist helps:
- Equity left after your first mortgage, and a credit profile that fits the tier you want.
- A DSCR lender that accepts borrowed down payment funds in writing.
- Reserves held separately from the draw.
- A rental whose coverage still holds after you add the line’s payment to your budget.
- A realistic plan to pay the line down, not just carry it.

Exit Plans: Paying the Line Back
You have three realistic routes.
Pay it down from rent and savings. Slow, steady, and low drama. It works best when the rental’s coverage leaves real room.
Refinance the rental. After seasoning, a cash-out refinance can pull equity out of the rental to pay the line. The leverage cap and any prepayment penalty on the first DSCR loan both matter here. Check them before you buy, not after.
Sell. It ends both obligations. It also ends the investment.
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.
Frequently Asked Questions
Can I use a HELOC for the entire purchase?
Usually not. A line supplies cash, but a DSCR lender typically wants meaningful skin in the game and sourced funds. Most purchase files land at 75%-80% LTV, so the down payment is 20%-25%. Whether a lender lets borrowed money cover all of it varies by lender, so ask first.
Does the rental’s rent count toward qualifying for the HELOC?
No. A primary-home line is qualified on your credit, your equity, and your debt-to-income ratio. Rent from a property you have not bought yet does not enter that review. Rent matters on the DSCR loan, where it is compared with the new loan’s PITIA.
Does the HELOC payment lower my DSCR?
Generally no, because the ratio compares rent with the rental’s own PITIA. The line’s payment still reduces your real cash margin. Treat it as a cost of the strategy even though the ratio ignores it.
What if the line is reduced or frozen before I close?
It can happen, which is why timing matters. Draw the cash and move it to your own account before you commit to a contract. Keep the statements, and keep some additional cash outside the draw as a cushion.
Can I get this home equity line in any state?
Not everywhere. Lendmire’s home equity lines are available only in the 16 states where it offers full-service lending. That footprint is narrower than its DSCR investor loan reach across 41 markets, including Washington, D.C.
