The Quick Read: Keep the low first and add a home equity line when the cash need is small next to the first balance; consolidate into one DSCR cash-out loan when the first is not worth protecting, the title sits in an LLC, or the borrower’s file cannot support a line. A cash-out refinance reprices the whole balance, while a line prices only the new money.
- A line adds a new lien behind the first. A cash-out pays off the first and writes a larger one.
- On an investment property, a home equity line tops out at 70% CLTV and a $500,000 line, with a 700 credit floor.
- A DSCR cash-out on a standard rental reaches about 75% LTV and qualifies primarily on property-level rental income covering the payment, subject to lender guidelines.
- A line is read on the borrower’s credit and debts. A DSCR cash-out is read on the property.
- Clearing 1.00x coverage does not mean the property cash-flows.
What “Consolidate” Actually Means
The word covers three different moves, and mixing them up is how files go sideways.
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 first is a single-property cash-out. The new loan pays off the old first and any junior liens, and the borrower keeps the difference after costs. The second is a pooled structure, where several rentals sit under one note. The third is the keep-first route: leave the first alone and add a line behind it.
This article centers on the first and third, because that is where most investors actually choose. The core question is simple. Do you add debt, or do you replace it? Everything else follows from the answer.
For the wider picture of how these loans are structured, see the complete DSCR loans guide.
Why a Low First Mortgage Is Worth Protecting
A low first earns its keep because it prices the biggest slice of your debt. When you add a second lien, the old first keeps its original pricing. Only the new money carries today’s cost of borrowing.
The blended cost is a weighted average. Weight each loan by its balance, then combine. If the new money is a small share of total debt, the cheap first dominates the blend. If the new money is a large share, the blend drifts toward the new pricing.
A refinance works the other way. The whole balance moves to new pricing, including the portion that was already cheap. That repricing is usually the largest cost in the decision, and it hides inside the phrase one simple payment.
There is a time element too. A line is usually variable, so its cost can climb after closing. A fixed refinance gives certainty on the full balance. The low first versus the new fixed loan is therefore not a pure price comparison. It is also a question of how much uncertainty you will carry.
How Underwriting Reads Each Path
The two paths ask different questions, so a file that fails one can pass the other.
A home equity line is underwritten on the borrower. The reviewer looks at credit, debt-to-income, occupancy, and combined loan-to-value. Rent does not size the line. A DSCR cash-out is underwritten on the property. Coverage is monthly rent divided by the monthly housing obligation: principal, interest, taxes, insurance, and any HOA dues.
Here is how the pieces compare on the network’s investment-property terms.
| Factor | Keep first + HELOC | DSCR cash-out |
|---|---|---|
| Existing first | Stays in place | Paid off |
| What reprices | New money only | Entire balance |
| Read on | Borrower file | Property rent |
| Ceiling | 70% CLTV, investment | About 75% LTV, standard rental |
| Size | $25,000 to $500,000 line | Up to $3,000,000 on standard programs |
| Title | Individual or revocable trust | LLC possible, per program eligibility |
| Payment shape | Interest-only draw, then amortizing | Fixed spine, 30-year |
The line figures apply to an investment property. A primary-residence line follows different tiers, and those tiers do not carry over to a rental.
Path A: Keep the First and Add a Second Lien
Sizing starts with combined LTV. Add every lien, divide by appraised value, and compare against the ceiling. The room left for a second equals value times the CLTV ceiling, minus the first balance.
Run it as a modeled example. Say the first sits at 55% of value. Under a 70% CLTV ceiling on an investment property, the second can reach about 15% of value, subject to line minimums and the borrower’s file. If the first already sits near 70% of value, there is essentially no room at all.
Several mechanics shape the line on the network:
- Structure. An investment line runs a 5-year interest-only draw followed by a 25-year fully amortizing repayment. Pricing floats through both periods and never converts to fixed.
- Draw at closing. At least 75% of the line is drawn at closing. The revolving feature is smaller in practice than the product name suggests.
- Credit and debt. The investment floor is 700. Debt-to-income caps at 50%, and the line is qualified on the interest-only payment at the maximum draw.
- Valuation. Because an investment line cannot exceed $500,000, it commonly runs on an automated valuation with no traditional appraisal. A borrower can still request a full one.
- Exposure. A borrower is limited to three lines, and an owner with more than 15 financed properties is not eligible.
The Ask CFPB explanation of a HELOC describes the general product: an open-end line you can draw on repeatedly during a draw period, usually with a variable cost. Some plans in the wider market let you convert part of the balance to fixed. The network’s investment line does not.
One caution on the draw period. The CFPB’s HELOC consumer booklet notes that interest-only draws put nothing toward principal. It also notes that on plans which include principal, the payments typically do not repay the balance by the end of the term. The payment can jump when repayment begins. Stress that step before you rely on the line.
Lendmire’s piece Is a HELOC the Right Way to Tap Equity and Keep a Low First Mortgage? covers the keep-first decision on its own.
Path B: Consolidate Into One DSCR Cash-Out
A DSCR cash-out is sized to the lower of two tests. The first is the LTV ceiling. The second is the largest loan the rent can support at the program’s coverage floor.
On most files across the wholesale network, cash-out on a standard rental reaches about 75% LTV. Short-term-rental collateral on a cash-out sits lower, at 70% LTV. Seasoning is typically about 6 months of ownership. Coverage of 1.00x is where select programs start. A separate select-lender path takes coverage below 1.00 with leverage and terms adjusted, so a thin file is not automatically a dead one.
The mechanics run in order:
1. The appraisal sets value and a rent opinion.
2. The new loan is sized against the LTV ceiling and the coverage test.
3. The payoff of the old first, any junior liens, closing costs, and any prepayment charge come out of the new loan.
4. What remains is the cash to the borrower.
That fourth step is where expectations break. Investors read the maximum loan as the check. The check is the maximum loan minus everything that has to be settled first. On a property with a large first balance, little may be left.
Reserves are commonly around 6 months of PITIA, though they vary by lender, leverage, loan size, and transaction type. Loans above $1,500,000 typically step up to about 9 months. Above $2,500,000, the network generally holds to 30-year fixed structures. Extended terms, interest-only periods, and ARMs are available through select lenders for investors who want them.
The paperwork is straightforward. Expect a lease or rent schedule, entity documents if the property sits in an LLC (subject to program eligibility), a title review, and the appraisal. The weak spot on these files is usually the lease evidence or an entity document that does not match the vesting on title.
A Side-by-Side Worked Example
Run the numbers on a modeled rental with a first at 50% of value. The figures below are percentages and ratios, not market data.
Keep-first path. The 70% CLTV ceiling leaves room for a second of up to 20% of value. The first stays untouched. Only the new money carries new pricing.
Consolidate path. The 75% LTV ceiling allows a new first of up to 75% of value. After the 50% payoff, up to 25% of value is left before costs and any prepayment charge. That is more gross room than the line offers, but all of it carries new pricing, including the 50% that was cheap before. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
The coverage picture changes too. Take a modeled illustration where the first covers at about 1.40x. A modest second brings combined coverage to about 1.08x. A larger second brings it to roughly 0.88x. A rent-qualified second counts both payments against the rent. A standard line does not, because it is sized on the borrower. That is exactly why the line can reach a property that a rent-qualified second cannot.
The honest read is that neither path wins by default. If the new money is a small share of the property’s value, keeping the first usually costs less. If the new money is a large share, the gap narrows and the refinance’s fixed structure starts to matter.
Where the General Rule Breaks
The keep-the-first instinct fails in specific, nameable cases.
An existing second lien. In a cash-out, any junior lien has to be paid off or subordinated. The junior lender is under no obligation to agree. A zero-balance line still leaves a recorded lien until it is released. Check for stray liens before the file goes in.
LLC title. The network’s investment line cannot be held by an LLC, a corporation, a partnership, or an irrevocable, blind, or land trust. Only an individual or a revocable living trust can hold title. A DSCR cash-out can stay in the LLC, subject to program eligibility. Moving title just to qualify for a line can defeat the reason the entity exists.
Leverage already used. A first near 70% of value leaves no room under the 70% CLTV investment ceiling. The line is simply off the table.
Credit below 700. On an investment property, 700 is a hard floor with no tier beneath it. A DSCR cash-out is the realistic route for a lower score. Most programs want around 660, and a 620 floor exists in parts of the network. Credit still shapes leverage and terms.
Large portfolios and uneven income. An owner with more than 15 financed properties is not eligible for the line. An owner with several financed rentals and thin taxable income may also fail the borrower-based test. Rent-based underwriting reads the same files differently.
Cash needs above the cap. The investment line stops at $500,000. A larger need pushes toward the cash-out.
Property type. Both products have limits. DSCR on manufactured homes, log homes, and barndominiums is not offered through the network. The home equity line also excludes manufactured homes, co-ops, condotels, commercial, mixed-use, and agricultural zoning.
Availability. The line is offered in 16 full-service states, which is narrower than the 41-market DSCR footprint, Washington, D.C. included. An investor outside those states may find that the choice is made for them.
DSCR vs. conventional financing
There are two common ways to finance an investment property, and they qualify you differently — here’s how investors weigh them.
Why investors choose it
- Qualifies on the property’s rental income — no personal tax returns, W-2s, or pay stubs needed to document income.
- No personal debt-to-income ceiling to clear, so existing mortgages and obligations don’t cap your borrowing the same way.
- Can be closed in an LLC, keeping the property inside a business entity.
- Built for scaling — not held to the limit on number of financed properties that conventional financing applies.
- Underwriting centers on the deal: generally qualifies when the rent covers the payment, a 1.00x coverage ratio being a common baseline (confirmed in underwriting).
- Designed specifically for investment property, including long-term and, where the program allows, short-term rentals.
Where it’s strong
- Often the lowest ongoing financing cost for a buyer who fully qualifies on personal income — a fit for a first property or a cost-first purchase.
Trade-offs for investors
- Requires full personal income documentation and must fit within a debt-to-income limit — salary, existing debts, and other mortgages all count.
- Typically held in your personal name rather than a business entity.
- Caps how many financed properties you can carry, which can become a ceiling as a portfolio grows.
- Evaluates you as a borrower as much as the property, which usually means more paperwork.
How investors usually choose: a first or single property often optimizes for the lowest financing cost; portfolio builders often optimize for leverage, vesting in an LLC, and scaling past conventional caps. The right answer depends on your goals, the property, and current guidelines — both paths run through select lenders in Lendmire’s wholesale network, with eligibility and terms confirmed in underwriting.
The Hybrid Most Investors Skip
The choice does not have to be all or nothing. The cleaner structure for a mixed holding is often one loan of each type.
Say you own two rentals. One is titled personally, with a cheap first and plenty of equity. The other sits in an LLC, with a higher-cost loan you would rather replace. A line on the personal property and a DSCR cash-out on the LLC rental is a coherent plan. Each loan is matched to the title and the underwriting lens that fits it.
The same logic applies to triage inside a larger portfolio. Loans worth replacing tend to be short-term, bridge, or hard-money debt, or loans with a junior lien attached. Loans worth leaving alone tend to be long-dated, fixed, and priced well below today’s market. Blending everything into one note simply because one payment sounds tidy gives up the most valuable asset you hold, which is the cheap debt.
What DSCR Coverage Does and Does Not Prove
Coverage compares rent to PITIA and nothing else. Clearing 1.00x means the rent covers the housing obligation on paper. It does not mean the property cash-flows. Repairs, vacancy, management, utilities, and capital expenses all sit outside the ratio.
This matters most on the consolidate path. Pulling out the maximum raises the obligation on the same rent, so coverage falls. Test the larger payment against rent before you commit, and test the line at its worst plausible draw, not at its opening balance.
A larger equity cushion helps, but it does not erase the other gates. Leverage caps, credit floors, reserve rules, and property eligibility all still apply. The strongest files clear two tests at once: enough equity and enough rental coverage.
The Cost Items People Forget
A cash-out check is not free money. Payoff, closing costs, reserves, and any prepayment charge on the old loan come out first. If a hard-money or bridge loan carries an exit fee or per-diem interest, count it as part of the consolidation cost.
Running a line and then refinancing it out later means two sets of closing costs. Fees on a short hold are hard to recover. Spread the fees over the months you will actually hold the loan, then compare.
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.
Pick Your Profile
| Profile | Likely fit |
|---|---|
| Small cash need, cheap first, personal title | Keep first + HELOC |
| Large cash need, first near the leverage cap | DSCR cash-out |
| LLC title, no wish to retitle | DSCR cash-out |
| Credit under 700 | DSCR cash-out |
| Existing junior lien, subordination unlikely | DSCR cash-out |
| Several rentals, mixed titles | Hybrid |
| Cash need is uncertain or short-term | Keep first, or do nothing yet |
Doing nothing is a real answer. If the cash need is vague, an unused line can wait, and so can the refinance.
Key Terms Defined
CLTV: Combined loan-to-value, meaning all liens added together and divided by appraised value.
Cash-out refinance: A new, larger first lien that pays off the old one and returns the difference to the borrower.
Draw period: The stretch of a line during which you can borrow against it, typically interest-only on the network’s investment line.
Subordination: A junior lender’s agreement to stay behind a new first lien. It is not automatic.
DSCR: Monthly rent divided by the monthly housing obligation, used to size and approve an investor loan.
PITIA: Principal, interest, taxes, insurance, and any association dues.

Frequently Asked Questions
Can I refinance several rentals into one loan?
Sometimes. Pooled notes exist in parts of the market, but availability depends on the lender, the properties, and the file. Each property is still appraised, and weaker properties can drag on a pool. A property-by-property cash-out is the more common route across the network.
Do I lose my low first if I use a HELOC?
No. A line sits behind the first lien and leaves it untouched. The new money is priced separately, and the line is sized on combined leverage and the borrower’s file, not on rent. On an investment property, the ceiling is 70% CLTV.
Can I put a HELOC on a rental held in an LLC?
Not on the network’s investment line. Title must sit with an individual or a revocable living trust.
What if my coverage falls below 1.00 after consolidating?
A 1.00 coverage ratio is where select programs start. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Expect lower leverage or different terms, and review the whole file before assuming either path.
Does a HELOC convert to a fixed payment later?
Not on the network’s investment line. Pricing floats through both the draw and the repayment period. Some plans elsewhere allow converting part of the balance to fixed, so confirm the structure of any line you are offered.
