The Quick Read: Only when three tests are met: the rental’s income must cover its own loan with room to spare, the purchase lender must accept borrowed down-payment money, and you must be comfortable putting the home you live in behind the investment, because a home equity line of credit (HELOC) supplies cash only and a separate loan buys the rental. The two loans are underwritten separately, and a weak rental can put your house at risk.
- A HELOC on your home is not the purchase loan. It releases cash, and a DSCR loan (a loan qualified on the property’s rent) buys the rental.
- Treatment of borrowed down-payment money varies by program, so ask the purchase lender before you draw.
- Down payment and cash reserves are separate tests, and one line rarely fills both.
- The line has to exist before you go under contract.
- Clearing the rental’s coverage test does not mean the deal makes money each month.
Key Terms Defined
CLTV (combined loan-to-value): Your first mortgage plus the new line, divided by the home’s value.
Draw period: The early years when you can borrow from the line and pay interest only.
PITIA: The full monthly housing cost of the rental: principal, interest, taxes, insurance and any association dues.
Reserves: Liquid cash a lender wants left over after closing, commonly around six months of PITIA on DSCR files.
Seasoning: The waiting period a lender wants between two events, such as cash arriving in your account and the purchase.
Recourse: The lender can pursue you personally for a shortfall, not just the collateral.
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.
Why Homeowners Ask This Question
Homeowners ask because their house is often their biggest pile of idle cash. A first-lien or second-lien line against a primary home can reach higher leverage than a line against a rental. Our network’s primary-residence ceiling reaches 90% CLTV, but only at a 720-or-better credit profile. Investment-property lines stop at 70% CLTV.
That gap is the whole temptation. It also explains the risk. The cheaper source of cash comes from the asset you can least afford to lose.
A DSCR-only purchase can cost you the rental and your down payment. A purchase funded by a line on your home adds a second exposure. The lien sits on the house you live in, so a failed rental can reach the place your family sleeps.
How a Line on Your Home Differs From the Rental Loan
The two loans answer different questions. The HELOC on your home is underwritten on you (Lendmire’s piece on whether to tap primary home equity with a HELOC goes deeper). The lender looks at your credit, your equity and your debt ratios. On our network, debt-to-income tops out at 50%, and a ratio above 45% needs a score of at least 680.
The DSCR purchase loan is underwritten on the property. The lender divides monthly rent by the full monthly housing cost of the rental. Business-purpose investor loans like this are reviewed differently from a standard owner-occupied mortgage.
Here is how the two compare in practice:
| Factor | HELOC on your home | DSCR purchase loan |
|---|---|---|
| What it does | Releases cash | Buys the rental |
| Underwritten on | You: credit, equity, debts | Property rent vs. PITIA |
| Collateral | The home you live in | The rental |
| Main risk | Losing the home | Losing the rental and down payment |
Because they are separate files, approval on one says nothing about the other. A strong line can still fund a rental the purchase lender won’t touch. That is why order matters, and the steps below put it in sequence.
How to Tap Primary-Home Equity to Buy a Rental, Step by Step
1. Open the line before you go under contract. You cannot open a line against a property you haven’t bought. The cash has to come from something you already own, so the line exists first.
2. Ask the DSCR lender before you draw. Across our wholesale network, programs sort into three camps on borrowed down-payment money. Some accept documented line proceeds. Others cap the borrowed share and want part of the down payment in your own seasoned cash. The strictest want that slice fully unborrowed.
A plan that is 100% borrowed can fail on that basis alone. Learn which camp your lender sits in before you pay for anything.
3. Build the paper trail. Lenders typically want the line’s closing documents, the draw confirmation, bank statements showing the cash landing in your account, and a credit report showing the new liability. Some also want the cash to sit in your account for a period before the purchase.
4. Remember the closing draw. On our network’s primary-residence lines, at least 75% of the line is drawn at closing. The cost of the line floats and never converts to fixed. You pay on most of the line from day one, whether or not a rental is under contract yet. Size the line to the need.
5. Keep reserves separate. Down payment and reserves are two tests. Line proceeds rarely fill both. Borrowed cash also never waives leverage caps, credit floors or reserve rules on the purchase loan.
6. Close the DSCR purchase. The appraisal includes a rent schedule, Form 1007 for a single-family rental or Form 1025 for two to four units. Those forms supply the rent figure the coverage test uses.
7. Plan the exit. Pay the line down from rent and savings, or refinance the rental later and retire the line. Draw periods end. On our network the primary-residence lines run either a 3-year interest-only draw followed by a 17-year repayment, or a 5-year draw followed by a 25-year repayment. When repayment starts, the payment steps up because you now pay principal too.
What Usable Equity Looks Like
Usable equity is the home’s value times the CLTV ceiling, minus what you still owe on the first mortgage. Work it in percentages first.
Say you own a home with a first mortgage equal to 50% of its value. At the 90% ceiling, which needs a 720-or-better profile, the line could reach up to 40% of value, subject to lender guidelines. At a 700 profile, the primary-residence ceiling is lower, so the room shrinks.
A Texas primary residence is a homestead and caps at 80% CLTV. The same 50% first mortgage leaves room for at most 30% of value. Lines range from $25,000 to $750,000, and anything above $500,000 is primary-residence only, with a full appraisal.
Lines at or below $500,000 ordinarily use an automated valuation instead of a traditional appraisal, though a higher CLTV may require a second valuation.
Availability is narrower than DSCR lending. These lines are offered through Lendmire only in its 16 full-service states: AL, CA, CO, FL, GA, IN, MI, MT, NM, NC, OH, PA, TN, TX, VA and WA. DSCR financing covers 41 markets, including Washington, D.C. Every figure here is subject to lender guidelines and full file review, and none is a commitment to lend.
Which Equity Product Fits Which Plan?
A line is not the only way to pull equity from a home. The right tool depends on whether you need a lump sum or staged access, and what happens to your first mortgage.
| Factor | Home equity loan | HELOC | Cash-out refinance |
|---|---|---|---|
| Payment type | Fixed lump sum | Draw as needed | New first mortgage |
| Cost behavior | Usually fixed | Floats | Set at closing |
| Best fit | One-time purchase | Staged purchases | Large need |
| Main risk | Home as collateral | Payment steps up | Replaces your first mortgage |
| Existing first mortgage | Stays | Stays | Replaced |
Cash-out refinancing on your home changes your whole first mortgage, which may be one you would rather keep. A line leaves it alone. Our network arranges standalone lines in either first-lien or second-lien position. A fixed second-lien loan and a cash-out refinance are separate products with separate guidelines.
What the Rental Itself Has to Do
The purchase loan has its own tests, and your home equity does not soften them. Most DSCR purchase files land at 75% to 80% LTV, which means 20% to 25% down. Select programs reach 85% LTV with roughly a 700 or better score. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
A 620 credit floor exists in parts of the network. Most programs want around 660, and 700 or better unlocks the strongest leverage tiers. Loans generally reach up to $3,000,000 on standard programs, with smaller balances available through select lenders.
On coverage, 1.00 is where many select 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. Reserves commonly run around six months of PITIA, though they vary by lender, leverage, loan size and transaction type.
One thing deserves emphasis. DSCR compares rent to PITIA and nothing else. Clearing 1.00 is not positive cash flow. Repairs, vacancy, management, utilities and capex all sit outside the calculation. Your line payment also usually sits outside the ratio, yet it still comes out of real cash.
A larger down payment lowers the monthly obligation and can lift the ratio. It never erases leverage caps, credit floors, reserve rules or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage.
Our network does not offer DSCR loans on manufactured homes, log homes or barndominiums, so a plan built around those fails at the property stage. For the full picture of how these programs work, see Lendmire’s complete DSCR loans guide.
Stress-Testing Both Loans Together
Run the deal as one picture: rent in, two obligations out. The table uses modeled assumptions, not market data.
| Case | What changes | Rental DSCR | Pressure on you |
|---|---|---|---|
| Base | Modeled rent clears about 1.25x | About 1.25x | Thin but positive |
| Vacancy | Rent stops for a stretch | Unchanged on paper | Both loans come from savings |
| Line cost rises | Floating cost climbs | Unchanged | Your personal load grows |
| Home value dips | Lender may cut or freeze the line | Unchanged | Lost access to cash |
Notice the pattern. None of the shocks moves the DSCR ratio itself, because the ratio is measured at closing. Every shock lands on your personal cash. That is why a file that clears the test can still be a bad idea.
In files like these, borrowers often model rent but forget that the line payment lands on the same rent check. Model the rent against both obligations before you draw.
How Much of Your Home Are You Risking?
Size the exposure honestly. A home equity line uses your home as collateral, and the Consumer Financial Protection Bureau notes that the lender could foreclose if you can’t repay. The same page carries a tip to be careful about borrowing against your home as part of an investment strategy.
Missed payments can move a line toward default and foreclosure, as Bankrate’s overview of HELOC defaults lays out. Depending on state law, a shortfall after foreclosure can follow you personally.
The loss is not capped at the rental. Ask a plain question: if the rental produced nothing for a stretch, could you keep both the line and your first mortgage current from your own income? If the answer needs a hopeful rent figure, the exposure is too large.
Two edge cases deserve a mention. If you sell the home, the line must be paid off at that sale. And if home values fall, a lender may reduce or freeze the line, which can strand a staged purchase plan midway.
Yes or No: A Decision Checklist
It leans yes when:
- You qualify for the line with room to spare on debt-to-income, not at the edge.
- The purchase lender has confirmed it accepts borrowed down-payment money.
- Reserves are available in your own cash, separate from the line.
- You could carry both obligations through a stretch of vacancy.
- You have a written plan to pay the line down or refinance the rental.
It leans no when:
- The plan depends on borrowing the down payment, the reserves and the repairs.
- The rental only works with optimistic rent or sub-1.00 coverage.
- Your household budget has no slack if the line cost rises.
- Your credit sits below the investment-line floor and you would be tapping the home just to compensate.
- You need the rental to fund your own housing stability.
Here is a case that lands on yes. Picture a homeowner with a 740 credit profile, a modest first mortgage and a duplex that clears its coverage test by a wide margin. The owner holds six months of reserves in separate savings and has confirmed that the purchase lender accepts documented line proceeds. The line is small, sized to the down payment, and the exit plan is written down.
Now picture a case that lands on no. A homeowner borrows nearly the full available equity and plans to cover reserves and repairs from the same line. The rental clears coverage by a hair. One vacancy later, three obligations come from one paycheck.
Alternatives Worth Comparing
Using your own cash gives the cleanest file but slows portfolio growth. Waiting and saving costs time and removes the home from the risk picture entirely.
A bank-statement line, which is reviewed around deposit history instead of tax-return income, can help self-employed owners. Lendmire’s piece How to Tap Home Equity on Bank Statements to Buy a Rental covers that route.
If you already own a seasoned rental, a line against it puts the lien on the rental instead of the home. On our network, investment lines cap at 70% CLTV and $500,000, with a 700 minimum credit score. They follow a 5-year draw and a 25-year repayment, with no other structure available.
One catch matters here. Our network’s lines require that the individual borrower or a revocable living trust hold title. An LLC cannot. A rental deeded to an LLC needs a vesting change first, or a DSCR cash-out refinance instead, subject to program eligibility. Cash-out refinances on rentals generally top out around 75% LTV, with about six months of seasoning as the common expectation.
A Word on Taxes
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 as the whole down payment?
Sometimes, but it is the riskiest version. Some DSCR programs accept documented line proceeds. Others cap the borrowed share or require part of the down payment in your own seasoned cash. A plan that is fully borrowed can fail on that point alone, so confirm the purchase lender’s position before you draw.
Will the purchase lender accept borrowed funds?
It depends on the program. Across our network, lenders fall into three camps: accept documented proceeds, cap the borrowed share, or require an unborrowed slice. Ask before drawing, and keep the paper trail: the line’s closing documents, the draw confirmation and the bank statements showing where the cash landed.
Does the line payment count against the rental’s coverage ratio?
Usually not. The DSCR ratio compares rent to the rental’s own PITIA. Your line payment is a personal obligation secured by your home. It still comes out of real cash flow, so a property can clear the ratio and still run tight.
Can I open the line after I find the property?
Not reliably. The line has to exist before you go under contract, and the purchase lender may want the cash documented first. Open it, ask the lender about borrowed funds, then start shopping.
Does a bigger down payment fix a weak rental?
It helps the ratio by lowering the monthly obligation, but it never overrides leverage caps, credit floors, reserve rules or property eligibility. Rent still has to cover the new loan with room to spare. A strong file clears both tests: enough equity and enough rental coverage.
Next Step
If you are considering a home equity line and want to see how the numbers work, Lendmire can help you compare home equity line options based on the property, the equity available, credit profile, combined leverage, and your goals. An illustrative calculator estimate can show the shape of the numbers before you commit to either loan. The decision that matters most is whether your household can absorb the rental’s worst month, because the home behind the line is the one asset you cannot replace.
