The Quick Read: A new first-lien loan pays off your old first mortgage, your second lien, and any other debts you choose, and you keep the leftover equity as cash. Nothing is literally merged. The old liens are paid off and released, and the new loan has to clear both the leverage cap and the rental coverage test.
- A second mortgage is usually paid off at closing, or the second lender is asked to step behind the new loan (subordination).
- Paying off a second lien is generally treated as cash-out, even if you take no cash.
- On a cash-out refinance of a standard rental, most programs in our network top out around 75% LTV. Short-term-rental collateral tops out around 70%.
- Every debt you roll in raises the new balance, so the coverage ratio drops unless the old second-lien payment disappears with it.
Picture an investor with a duplex, a first mortgage, a HELOC drawn for a rehab, and two credit cards carrying the rest of that rehab. Four payments on three kinds of debt. The goal is one loan and one payment, secured by the rental.
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 works for some investors and backfires for others. This guide covers the mechanics, how underwriting treats each piece, the structures that exist, and where the general rule breaks. It is written by a broker who places these files across a wholesale network of DSCR lenders. Program details change, and every file is underwritten individually.
Key Terms Defined
Cash-out refinance: a new mortgage larger than what you owe, with the difference paid to you after the old debts are cleared.
Lien: a lender’s legal claim on the property. The first lien gets paid first if the property is sold or foreclosed.
Second mortgage: a loan secured behind the first mortgage. A HELOC (home equity line of credit) and a home equity loan are both second mortgages.
Subordination: the second lender agrees to stay in second position behind a new first mortgage instead of being paid off.
DSCR (debt service coverage ratio): monthly rent divided by the full monthly payment on the property, including principal, interest, taxes, insurance, and any HOA dues.
LTV (loan-to-value): the loan balance divided by the appraised value.
Seasoning: the waiting period a lender wants between buying a property, or taking a prior loan, and refinancing it.
Payoff letter: a written statement from a lender showing the exact amount needed to close out a loan on a given day.
What Does “Combining” Actually Mean?
Combining is a payoff, not a merge. The new first-lien loan sends money to the old first-mortgage lender and to the second-lien lender. Both old liens are then released, and one new lien is recorded.
That distinction matters for two reasons. First, the title company needs a payoff letter for every lien, so each lender has to cooperate. Second, a HELOC does not disappear just because the balance hits zero. The line has to be formally closed and the lien released, or you are left with an open credit line on a property you thought was clean.
Debts that are not secured by the property work differently. Credit cards, a bridge loan, or a note on another property get paid off from proceeds at closing. The cash-out does not care what you spend the money on. Zillow’s cash-out refinance explainer notes there are no restrictions on how withdrawn cash is used.
A second lien secured by a different property is its own case. It is not a lien on this property at all. The cash-out simply repays it as a debt, the same way it would repay a credit card.
How Underwriting Treats the Stack, Step by Step
Underwriting looks at the whole transaction as one number: how big is the new loan, and does the rent cover it? Here is the order a typical file follows.
1. Build the payoff inventory. List the first mortgage, any HELOC or home equity loan on the same property, and every debt you want paid at closing. Get current statements for each.
2. Order the appraisal. DSCR underwriting rests on the appraised value and the rent. A quote may start from an assumed rent, but the final file uses the appraiser’s rent figure or the signed lease. A lower appraisal shrinks the cash available and moves the ratio at the same time.
3. Size by subtraction. Take the appraised value times the maximum LTV. Subtract the first-mortgage payoff, the second-lien payoff, the other debts, and closing costs. What remains is your cash.
4. Run the coverage test. The new, larger payment must be covered by rent. Each dollar rolled in raises the payment and lowers the ratio.
5. Handle title and closing. The title company collects payoff letters and pays each creditor from the closing statement.
6. Close the line. If a HELOC was paid off, confirm the closure and lien release in writing.
The payoff stack in one table
Here is a modeled example shown as shares of appraised value, not dollars. These are illustrative assumptions, not market data.
| Stack item | Share of appraised value |
|---|---|
| Appraised value | 100% |
| Maximum new loan (cash-out, standard rental, 75% LTV) | 75% |
| Old first mortgage payoff | 45% |
| Second lien payoff | 10% |
| Credit cards and other debts paid at closing | 4% |
| Closing costs | 2% |
| Cash left for you | 14% |
The subtraction is the whole trick. Add the payoffs and costs, subtract from the 75% ceiling, and what is left is yours. If the appraisal comes in light, every item stays the same size while the ceiling shrinks. The cash to you takes the hit first.
The Coverage Test Is Where Files Get Tight
Equity alone does not decide this deal. The rent has to carry the new payment.
Run the logic in ratios. Say a rental covered its first and second mortgage payments at about 1.35x. After a cash-out that adds consumer debt and extra cash to the balance, the single new payment might land near 1.10x. The second-lien payment vanished, but the larger principal more than made up for it.
That is a normal outcome. Rolling in a second mortgage by itself can help or hurt coverage, because you remove one payment and add its balance to the new loan. Rolling in cards and cash on top is what usually pushes the ratio down.
A DSCR of 1.00 is where many select programs start, and stronger ratios open better pricing and higher leverage. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. If your stack lands below 1.00, you can trim the cash-out, add a larger interest-only or extended-term structure through a select lender, or look at that sub-1.00 path. Qualification stays subject to lender guidelines and property review.
One more reality check. Clearing 1.00 is not the same as positive cash flow. The ratio compares rent to the property payment only. Repairs, vacancy, management, utilities, and capital expenses all sit outside it.
What the Network Typically Looks For
These are typical ranges across the wholesale network, not guarantees. Reserves vary by lender, leverage, and loan size.
| Factor | Typical read on a cash-out |
|---|---|
| Max LTV, standard rental | Around 75% |
| Max LTV, short-term rental | Around 70% |
| Seasoning | About 6 months is common |
| Credit score | 620 floor in parts of the network; most want about 660; 700+ for the strongest tiers |
| Loan size | Up to $3,000,000 on standard programs |
| Reserves | Commonly around 6 months of PITIA; often more on larger loans |
| Coverage | 1.00 is where many select programs start |
PITIA means principal, interest, taxes, insurance, and association dues. Short-term-rental collateral also tends to want a 640+ score and about 12 months of hosting history. Above $2,500,000 the network generally holds to 30-year fixed structures.
The spine of the product is the 30-year fixed. Extended terms such as 40-year and interest-only periods are available through select lenders in the network, and ARM structures exist for investors who want them. Manufactured homes, log homes, and barndominiums are not offered in the network’s DSCR programs.
DSCR underwriting looks at the property, so qualification runs primarily on property-level rental income covering the payment, subject to lender guidelines. Credit and reserves still matter. DSCR loans are designed for non-owner-occupied investment properties, and because they are business-purpose investor loans, they are reviewed differently from a standard owner-occupied mortgage.

Your Three Options for the Second Lien
| Option | What happens | Cash-out label | Fits when |
|---|---|---|---|
| Combine both | New loan pays off first and second | Yes | Second lien is costly or messy |
| Refinance the second alone | First stays; new second replaces old | Depends | First mortgage is very favorable |
| Subordinate | Second stays behind the new first | Usually yes | Second lender cooperates |
Combining both is the cleanest outcome. One lien, one lender, one payment. It is also the most common path, because most first-lien lenders want the second paid off before they take the first position.
Refinancing the second alone protects a favorable first mortgage. If your existing first mortgage is a good one, giving it up to reach a small second lien is usually a poor trade. We cover that tradeoff in Lendmire’s piece Second-Lien HELOC vs Cash-Out Refinance for a Low Fixed Mortgage.
Subordination asks the second lender to sign an agreement staying in second place. It sounds neat. In practice many lenders resist, and most new first-lien lenders still prefer the payoff.
Does Combining Save Money?
Sometimes. The honest answer is to test it, not assume it.
The method is simple. Add up what you pay each year on every debt you plan to retire: the first mortgage, the second lien, and each card or loan. Compare that with the yearly cost of the single new loan, plus the closing costs spread over how long you will keep the property.
The CFPB’s research on cash-out refinances and non-mortgage debt frames the same test. The refinance only makes sense when its total cost, interest plus origination fees, is lower than the cost of paying down the other debts on their own. That report also notes that paying off other bills or debts was the most common stated reason for cash-out refinancing among the survey respondents it analyzed.
Two traps hide inside that math.
The term reset. A new 30-year loan restarts the clock. A lower monthly cost can still mean more total interest over the life of the loan. SuperMoney’s debt consolidation guide makes the same point: a longer term can raise lifetime interest even when the rate drops.
The break-even. Divide your closing costs by your monthly savings. That is roughly how many months you need to hold the new loan before it pays for itself. If you may sell or refinance again before then, the combination loses.
Also weigh what you give up. An older first mortgage with a low fixed cost is hard to replace, and the new loan will reset your equity cushion to a thinner level.
Where the General Rule Breaks
The rule of thumb says a new loan pays off everything and counts as cash-out. These cases bend it.
The no-cash payoff. A new loan that pays off a HELOC is generally treated as cash-out even if you take zero cash. Some conventional programs carve out an exception for a second lien that funded the original purchase. DSCR lenders each set their own rule, so a piggyback second from the purchase may be treated more gently by one lender and not another. Confirm it in your scenario before you plan around it.
Seasoning and bridge loans. About 6 months of seasoning is the common expectation on a cash-out. A stabilized property refinancing out of a hard money or bridge loan may be treated differently by some lenders. Ask before you assume either way.
Short-term-rental collateral. The ceiling drops to around 70% LTV on a cash-out. The same stack that fits a long-term rental at 75% may leave you short on an Airbnb-style property. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
Holding title in an LLC. Investors often hold rentals in an entity. DSCR loans to LLC-titled properties are available subject to lender program eligibility. A different structure applies if you were thinking of a home equity line instead, because that product cannot be written to an LLC.
Mixing personal debts into a business-purpose loan. Under Regulation Z’s business-purpose rule, credit to acquire, improve, or maintain non-owner-occupied rental property is deemed business purpose, and the lender must determine each transaction’s purpose case by case. Paying personal credit cards from a rental cash-out is a consumer-style use of proceeds. How that affects the loan’s label is a question for the lender and counsel, not a rule of thumb.
Small multifamily you live in. Rules shift when you occupy one unit. DSCR programs are built for non-owner-occupied property, so an owner-occupied duplex is a different conversation.
The Risks Most Investors Underweight
Consolidation moves debt. It does not erase it.
Unsecured becomes secured. A credit card can hurt your credit through missed payments, and also through high utilization or changes to your accounts. Once the same balance sits inside a mortgage, the property backs it. The CFPB report warns that converting non-mortgage debt into mortgage debt can put the home at risk of foreclosure. For a rental owner, that means one property now backs a consumer debt.
Balances creep back. The strongest mistake is paying the cards off and then running them up again. Close the paid-off accounts, or at least cap them, if you want the move to stick.
Less cushion. A bigger loan against the same value leaves less margin if values dip. That makes selling or refinancing harder later. This is also why rolling short-term, near-paid-off debts into a 30-year loan is usually a bad idea.
Tax treatment. 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.
Payoff Mechanics and a Practical Sequence
Closing is mostly paperwork. The title company handles most of it, but you can prevent snags.
Gather these before you apply:
- Current statements for the first mortgage, second lien, and every debt to be paid.
- The lease or rent roll for the property.
- Proof of insurance and recent tax bills.
- Entity documents if the property sits in an LLC.
- Recent statements showing your reserves.
The sequence follows a pattern. Lenders issue payoff letters with a per-diem interest figure, which is the daily interest that accrues until funds arrive. The payoff amount on the letter is usually higher than the statement balance. Plan for that gap.
Consumer creditors can be paid directly from the closing statement, which keeps the cash from ever hitting your account. Afterward, confirm each lien release and each HELOC closure in writing. Do not skip that last step.
If the second lender will not cooperate, it is a problem. A lender that holds up the payoff letter, or refuses to subordinate, can stall the entire file. Raise it early. When the second lender cannot be moved, ask your broker whether a different structure fits.
Alternatives Worth Weighing
You do not have to combine everything.
Keep the second and add nothing. If the second lien’s payment is manageable and the first is favorable, leave both alone and tackle the consumer debt another way.
Use a standalone home equity line instead. On this network, an investment-property line is capped at 70% CLTV and $500,000 total, with a 700 credit minimum. Title must be held by an individual or a revocable trust, and availability is narrower than the DSCR footprint.
Pay down consumer debt another way. A personal loan or balance transfer keeps the debt unsecured and leaves the property out of it.
Roll in only the property-related debts. A bridge loan or rehab HELOC tied to the same property is the cleanest to fold in. Personal credit cards are the riskiest.
Frequently Asked Questions
Is it a cash-out refinance if I take no cash?
Usually yes, when a second lien is paid off. A new loan that retires a HELOC or home equity loan is generally treated as cash-out even with no cash to you. Each DSCR lender applies its own guidelines, and a second that funded the original purchase may be viewed differently, so confirm the treatment in your scenario.
What if my second lender will not cooperate?
Start early, because the second lender’s payoff letter controls the timeline. If it refuses to subordinate, the usual fix is a payoff from the new loan. If it still stalls, a broker with several lenders may find a program that handles the stack differently.
Will my credit score drop?
Applying involves a credit pull, which can cause a small dip. Paying cards to zero can help your utilization, but scores respond differently on every file. Closing the paid-off accounts can also change your credit history length.
Can I include a HELOC in the new loan?
Yes, and it is one of the most common structures. The new first lien pays off the HELOC, and you should request that the line be closed and the lien released. Without that step, an open line can remain.
Can closing costs be rolled in?
Closing costs come out of the available proceeds, within the LTV cap. They reduce the cash you receive instead of adding to the ceiling. If the stack is already near the maximum, costs can squeeze your cash to zero.
Making the Call
If you are weighing a home equity line against a cash-out refinance and want to see how the numbers work, Lendmire can help you compare options based on the property, the equity available, your credit profile, combined leverage, and your goals. The brokerage arranges DSCR financing in 41 markets, including Washington, D.C., through select lenders in its wholesale network. You can reach the team at 828-256-2183.
The decision usually comes down to two checks. Does the new loan leave enough equity under the leverage cap? Does the rent still cover the bigger payment? If either answer is a stretch, rolling in fewer debts will usually serve you better than rolling in all of them.
