The Quick Read: A cash-out refinance and a HELOC fund a renovation or ADU in different ways. The right pick usually turns on how the property is titled and what you qualify on. A cash-out replaces your first loan with a larger one and pays you in one lump sum. A HELOC (home equity line of credit) adds a line on top of the loan you already have.
- Titling decides a lot. The HELOC lines in Lendmire’s wholesale network need an individual or a revocable living trust on title. A property held in an LLC usually points to a DSCR cash-out, subject to lender program eligibility.
- Investment HELOC limits: on an investment property, the network ceiling is 70% CLTV with a $500,000 maximum line and a 700 minimum credit score.
- DSCR cash-out limits: on a standard rental, cash-out tops out around 75% LTV across most of the network. Short-term-rental collateral runs closer to 70%. Expect about 6 months of seasoning.
- Neither option credits the finished project. Both size off what the property is worth today.
- The review basis differs. A HELOC leans on your personal credit and debt load. A DSCR cash-out leans on property-level rent coverage, subject to lender guidelines.
Who Each Option Is Really For
A HELOC fits an investor with strong personal income, modest debt, and a first mortgage worth keeping. It also fits a project with uncertain costs. A DSCR cash-out fits an investor whose property sits in an LLC, whose personal debt-to-income ratio is thin, or whose rents carry the file.
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.
Neither one is a cheaper version of the other. They are different structures built for different borrowers. The checklist below helps you sort yourself in before you pick.
Side-by-Side
The table shows the DSCR cash-out as Lendmire’s network places it. The HELOC column shows the network’s investment-property line unless noted. Terms vary by lender, and every file is reviewed individually.
| Factor | DSCR Cash-Out Refinance | Investment HELOC |
|---|---|---|
| Review basis | Rent coverage of the payment | Personal credit and DTI |
| Documentation | Lease or rent schedule, title, payoff | Personal credit and debt review |
| Property types | 1-4 units, condos, townhomes | Single-family, 2-4 units, PUD, condo |
| Entity vesting | LLC possible, per program terms | Individual or revocable trust only |
| Funding style | One lump sum at closing | Line with at least 75% drawn at closing |
| First mortgage | Paid off and replaced | Stays in place |
| Reserves | Commonly around 6 months of PITIA | Vary by lender and file |
| Leverage ceiling | About 75% LTV (70% on STR) | 70% CLTV, $500,000 max line |
PITIA stands for principal, interest, taxes, insurance, and association dues. CLTV is combined loan-to-value, which counts every loan against the property. Seasoning is the waiting period a lender wants after you buy before it will lend against the property.
When a Cash-Out Refinance Is the Better Fit
A cash-out refinance fits when the property is in an LLC, the project is large, and the rents are strong. It also fits when the existing first mortgage is not one you are protecting. You get one closed-end loan and one lump sum, with no line to manage.
A California legislative hearing packet describes the mechanics well. A cash-out refinance replaces the current mortgage with a larger one, and the borrower receives the difference in cash. Everything gets repriced and re-underwritten at the new balance. That is a real cost if your existing loan is one you would rather keep.
DSCR loans are designed for non-owner-occupied investment properties. Because they are business-purpose investor loans, they are reviewed differently from a standard owner-occupied mortgage. The lender asks whether the property’s rent covers its monthly obligation, not whether your pay stub does.
Here are the numbers that matter across most programs we place files with:
- Leverage: about 75% LTV on a standard rental cash-out. Short-term-rental cash-out runs 70%.
- Seasoning: about 6 months is the common expectation.
- Credit: a 620 floor exists in parts of the network, most programs want around 660, and 700 or better opens the strongest tiers.
- Coverage: 1.00 is where many select programs start. A separate select-lender path goes below 1.00, with leverage and terms adjusted.
- Loan size: up to $3,000,000 on standard programs (smaller balances available through select lenders), and above $2,500,000 the network generally holds to 30-year fixed structures.
Clearing 1.00 does not mean positive cash flow. DSCR compares rent to PITIA only. Repairs, vacancy, management, utilities, and capital expenses sit outside the calculation.
A cash-out is also the usual answer when a rental is already deeded to an LLC. Investors who want that structure left alone should not expect an equity line to accommodate it.
The cost that surprises people
A lump sum starts costing money on the full new balance from closing. If you pull cash for a build that will not spend it for months, you carry the extra balance while the money sits. That is why the schedule of your contractor matters as much as the product.
When a HELOC Is the Better Fit
A HELOC fits when you want to keep your first mortgage, own the property personally, and qualify on strong personal credit. It leaves the current loan alone. It is a second lien, or a first lien if there is no mortgage at all.
The CFPB describes a HELOC as an open-end line of credit you can borrow against repeatedly. It runs in two stages: a draw period, then a repayment period. Payments are often significantly higher in repayment. The cost on these lines usually floats rather than staying fixed.
Here is how the network’s investment line is built:
- Structure: a 5-year interest-only draw followed by a 25-year fully amortizing repayment. Investment lines use that structure only.
- Size: $25,000 up to $500,000 total on an investment property.
- Leverage: 70% CLTV is the ceiling on an investment property, with no tier above it.
- Credit: 700 minimum on an investment line.
- Debt load: a 50% maximum DTI, qualified on the interest-only payment calculated on the maximum draw.
- Valuation: lines at or below $500,000 ordinarily use an automated valuation rather than a traditional appraisal.
A HELOC on a primary residence gives a wider range. The ceiling reaches 90% CLTV, but only at a 720 or better credit profile and only on lines up to $500,000. Treat that figure as a primary-residence number. It never describes an investment property.
Two limits catch investors off guard. First, at least 75% of the line is drawn at closing. That is not the flexible, borrow-as-the-bills-come-due behavior many people picture. Second, after closing, the minimum further draw is $1,000 under the program that states one.
HELOC lines in this network are limited to Lendmire’s 16 full-service states. That is narrower than the 41-market DSCR footprint, which covers 40 states plus Washington, D.C.
The CFPB’s HELOC brochure also notes that lenders generally can freeze or reduce a line if the home’s value falls or your finances worsen. On a phased build, that matters. A funded cash-out has no equivalent draw risk.
Who gets turned away
LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title on these lines. A property already deeded to an LLC needs a vesting change or a DSCR cash-out instead. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not eligible either.
The Renovation and ADU Checklist
Work through these steps in order. Each one carries a lean.
1. Confirm occupancy. Owner-occupied or investment? Investment lines carry the 70% CLTV ceiling. Primary lines can go higher with stronger credit.
2. Confirm vesting. Individual or revocable trust leaves both options open. An LLC leans toward a DSCR cash-out.
3. Pull the first-mortgage payoff and terms. A first mortgage you want to keep leans toward a HELOC. One that is already costly to carry leans toward a cash-out.
4. Identify the value basis. Both options size off today’s value. A purpose-built renovation or construction loan is the only product that credits after-improvement value, as NerdWallet notes. Plan your budget on what the property supports now.
5. Decide lump sum or phased need. One fixed bill leans toward a cash-out. Costs that may shift lean toward a line, keeping the 75% drawn-at-closing rule in mind.
6. Identify your qualification strength. Strong personal income and low debt lean toward a HELOC. Thin personal DTI and strong rents lean toward a DSCR cash-out.
7. Check your credit tier. A 700 score is the entry point for an investment HELOC. A cash-out has more room, with a 620 floor in parts of the network and about 660 on most programs.
8. Reserve for the build. Plan reserves, since an ADU earns no rent while it is under construction.
9. Gather documents. You will want the vesting deed, the current mortgage statement, a lease or rent schedule, the scope of work with bids, permits, and proof of reserves.
10. Check the permit status. An unpermitted structure can hold back the valuation or the refinance that follows.
What Changes the Answer
A few conditions flip the lean:
- The property moves into an LLC. A HELOC drops out and a DSCR cash-out takes over.
- The project grows past the line. A $500,000 investment ceiling can be smaller than the plan. A cash-out can run larger, up to the loan sizes noted above.
- Seasoning is not met. A property bought recently may not satisfy the 6-month expectation. A HELOC may be worth a look in that gap.
- The existing mortgage matters to you. Keeping it favors the line. Resetting it favors the cash-out.
- Credit sits between 620 and 699. An investment HELOC is out of reach. A cash-out may still work, with leverage and terms adjusted.
- Costs are uncertain. A line gives some room, but the freeze risk and the 75% draw at closing trim that advantage.
Where Both Options Fall Short on an ADU
Neither product credits the ADU before it exists. That surprises investors who assume a finished-value appraisal is built in. A HELOC sizes off today’s value. A DSCR cash-out sizes off the lender’s own appraisal of the property as it stands. The improvement may support a higher appraised value later, depending on comps and underwriter review.
Rent from a planned ADU does not help either. A personal-income HELOC does not use projected rent at all. A DSCR file normally needs a lease or a market-rent appraisal on the property as it exists, using the standard rent schedule form. The new unit starts counting only once it is built and leased.
One workable sequence is to fund the build with a line, then refinance once the ADU is leased and seasoned. That plan carries two sets of costs and a lender decision at each step. Run the full cost of both steps before you commit.
A worked example
Say you own a fourplex that sits inside an LLC. You want to add a detached ADU on the lot. Your personal debt is already heavy because of the rest of your portfolio.
A HELOC does not work here. The LLC cannot hold title on the line, and your personal DTI would be the deciding test. A DSCR cash-out reviews the building’s existing rents against the new payment. Suppose the current rents cover that payment at roughly 1.2x. Then the cash-out fits the file, subject to lender guidelines, at around 75% LTV on a standard rental.
The ADU rent is not counted at the start. You carry the build out of reserves and existing rents. Once the unit is leased, a later refinance can bring its income into the file.
Mistakes That Cost Investors
- Borrowing to the ceiling. Max leverage leaves no room if the appraisal or the budget slips.
- Skipping the reserve. An ADU produces no rent during construction.
- Treating 1.00 as cash flow. Coverage compares rent to PITIA only.
- Ignoring the draw rules. A line that funds mostly at closing is not a flexible draw line.
- Assuming the LLC protects the file. Personal credit still carries a HELOC. The entity also cannot hold title on one.
- Forgetting the permit. Unpermitted work can complicate valuation and a later refinance.
Many practitioners also see investors forget that a larger down payment or a lower balance helps coverage but never erases a leverage cap, a credit floor, or a reserve rule. The strongest files clear both tests: enough equity and enough rental coverage.
The Verdict
Choose the HELOC when you hold the property personally, keep a first mortgage worth protecting, carry strong credit and low debt, and need the project size to fit under the $500,000 investment ceiling. Choose the DSCR cash-out when the property is in an LLC, personal DTI is thin, the project is large, and the rents carry the file.
If neither fits, a purpose-built renovation loan may be the better tool, because it can look at the finished value. Reserves, seasoning, and credit tier decide most of these files before price ever comes into play.
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 cash-out refinance to build an ADU?
Yes, if the property qualifies as a rental and the file clears lender review. On a standard rental, cash-out tops out around 75% LTV across most of the network, with about 6 months of seasoning expected. The lender sizes the loan off today’s value, so the unbuilt ADU adds nothing to the budget.
Which is better for costs that arrive in stages?
A line is built for staged costs, but the network’s investment line draws at least 75% at closing. That limits the benefit. A cash-out gives one lump sum and starts costing on the full balance right away. If you need true phased funding, ask about a renovation or construction loan.
Can I get a HELOC on a property held in an LLC?
Not through this network. The property needs to be held by an individual or a revocable living trust. A DSCR cash-out is the usual path for entity-held rentals, subject to program terms.
Can I use both a HELOC and a cash-out refinance?
Yes, in sequence. Some investors fund the build with a line, then refinance once the ADU is built and leased. Each step needs its own approval and carries its own costs, so run both before committing. A line also has to be paid off or subordinated at the refinance.
Does ADU rent count toward my DSCR?
Only once it is real. A DSCR file normally needs a lease or a market-rent appraisal on the property as it stands. Projected rent from a unit not yet built does not usually count. NerdWallet notes that rent counting depends on the loan program.
