The Quick Read: The right program for a big rehab is a standalone line secured by the rental, capped at 70% combined loan-to-value on an investment property, and it fits best when your first mortgage is worth keeping and your personal credit and debt can carry a second loan.
- An investment property line tops out at $500,000 and 70% combined leverage, with a 700 minimum credit score.
- The lender reviews you, not the rent, so your credit and debt-to-income ratio decide the file.
- Lenders size the line on today’s value, not the after-repair value, so the rehab cannot fund itself on paper.
- At least 75% of the line is drawn at closing, so a line on a rental is a poor fit for work that needs money released slowly in phases.
- A cash-out refinance underwritten on rental coverage is the main alternative, and it wins in several common situations.
What Makes One Program “Best” for a Major Renovation?
No single program wins for every investor. The best program for your situation depends on five things: who holds title, how much equity is left after your first mortgage, how your personal debt looks, whether the unit is occupied during the work, and whether the first mortgage is worth keeping.
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.
Lendmire is a mortgage broker, not a lender. It works with a network of wholesale lenders and matches your property and profile to the program that fits. Different lenders in the network weigh the same file differently. That is the reason to compare before you commit.
A renovation is a good test for any financing product, because the money leaves in lumps. Contractors want deposits and milestone payments. Materials arrive before the work is done. The unit may sit empty for part of the project. A product that handles those realities well is “best” for that job. A product that looks cheap on paper but breaks when the unit goes vacant is not.
Use these five criteria as a checklist:
1. Title fit. Can the property be held the way you hold it today?
2. Equity fit. Does the leverage cap leave enough room after your current liens?
3. Qualification fit. Does the lender judge you, or the property?
4. Timing fit. Does the product work while the unit is vacant or mid-rehab?
5. Exit fit. Do you have a plan for when interest-only payments end?
Key Terms Defined
HELOC: a home equity line of credit, which is a revolving loan you can draw from repeatedly, up to a set limit, while your home or rental secures it.
CLTV: combined loan-to-value, meaning all loans secured by the property, added together, divided by the property’s value.
Second lien: a loan that sits behind your first mortgage in repayment priority. On this network, a line can also sit in first position when no mortgage exists.
Draw period: the stretch when you can borrow from the line and typically owe interest-only payments.
DSCR: debt service coverage ratio, which compares a property’s monthly rent to its full monthly housing payment.
PITIA: principal, interest, taxes, insurance, and any association dues, which together make up that full payment.
How Underwriting Treats an Investment Property Line, Step by Step
A HELOC on a rental is underwritten to you personally. The lender looks at your credit, your debts, and the equity in the property. Rent is not the qualifying income the way it is on a DSCR loan. Here is how a file moves.
Step one: the property gets screened. On this network, an investment line can be secured by a single-family home, a 2-4 unit property, a PUD, a townhome, or a condominium, including non-warrantable condos. Manufactured homes, co-ops, condotels, log homes, commercial and mixed-use properties, and agricultural zoning are not eligible.
Step two: title gets checked. The property must be held by you as an individual, or by your revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title on the line. Plenty of investors hold rentals in an LLC, so this is often the first deal-breaker.
Step three: value is set. Because an investment line caps at $500,000, and full appraisals are required only above that size, these files commonly run on an automated valuation with no traditional appraisal. A higher CLTV may call for a secondary valuation, and you can request a full appraisal. Either way, the value reflects the property as it stands today.
Step four: the equity test runs. Take the value, apply the 70% CLTV ceiling, and subtract what you owe. What remains is the most the line can be, up to $500,000. Credit above 700 does not raise this ceiling. A 720 score and a 700 score both reach 70% on an investment property.
Step five: your profile is reviewed. The minimum credit score on an investment line is 700. The score comes from a single-bureau model keyed to the primary wage earner, and the report can be no more than 90 days old at closing. Debt-to-income can run up to 50%. The lender reviews your file on the interest-only payment calculated as if the line were fully drawn, which is a stricter test than your actual draw. Bankruptcy needs 4 years of seasoning. Investment files follow a 7-year path for foreclosure and 4 years for a deed-in-lieu, pre-foreclosure, or short sale.
Step six: exposure limits apply. A borrower is limited to three lines in total. Combined exposure across those lines is capped at $2,000,000 under the higher-leverage program and $750,000 under the longer-runway program, which are the two structures the network offers. The investment line itself still stops at $500,000 and 70% CLTV. A borrower with more than 15 financed properties is not eligible. Programs change and every file is underwritten individually, so treat every figure here as subject to lender guidelines and full file review.
Availability is also narrower than the DSCR side of the business. Lendmire’s equity line programs run in its 16 full-service states, while its DSCR investor loans cover 40 states plus Washington, D.C., or 41 markets.
How the Line Actually Works After Closing
The mechanics matter because a renovation budget has to survive the repayment phase. A HELOC is an “open-end” line, and the Consumer Financial Protection Bureau explains that you can borrow up to the limit during the draw period, then borrowing stops and repayment begins. The agency notes that payments in repayment are often significantly higher, and that in some cases the whole balance can come due when repayment starts.
On an investment line in this network, the structure is a 5-year interest-only draw, followed by a 25-year fully amortizing repayment. At least 75% of the line is drawn at closing. Pricing floats during both phases and never converts to a fixed structure. Bankrate’s draw-period explainer describes the same basic pattern across the market: a draw period of up to 10 years with interest-only payments on what you borrow. Bankrate also notes that HELOCs typically carry a variable rate.
The 75% drawn-at-closing rule changes how you should think about a renovation. Many investors picture a line that sits unused until the contractor sends an invoice. On this network, most of the line is already borrowed on day one. If the project will cost far less than the line, you will be paying interest on money you are not yet spending. Size the line to the budget plus contingency, not to the maximum the equity allows.
The CFPB’s HELOC brochure adds that some plans require a minimum amount per draw or a minimum outstanding balance, and some require an initial draw at setup. Ask for these terms in writing before you pick a line size.
Worked Example: How Big a Line Does Your Equity Support?
Run the numbers on a rental held in your own name. Treat these inputs as modeled assumptions, not market data. Say the first mortgage sits at 50% of the property’s current value, and you want the line at the 70% CLTV ceiling for an investment property.
- Ceiling: 70% of value.
- Existing first mortgage: 50% of value.
- Room for the line: about 20% of value.
The $500,000 line cap binds only on very high-value properties. For most rentals, the equity test runs out first. Now change one input. If the first mortgage sits at 65% of value, the room shrinks to about 5% of value. That is probably too little for a gut renovation, and the line may not be worth setting up.
Notice what the test never includes: the after-renovation value. The lender sizes the line on what the property is worth before the work. A rehab that lifts the appraised value may support a higher valuation later, depending on comps and underwriter review. That lift cannot fund the project in advance. A post-rehab refinance or a second line comes after the work, not before it.
Then judge the payback honestly. A rent increase after renovation helps, but it only matters if it covers the new carrying cost on the line during the draw period and again when repayment begins. Budget for the vacancy while the work is underway, because the line’s payments start at closing whether or not a tenant is paying.
Three Ways to Fund the Same Rehab
| Option | Qualifies mainly on | Draw flexibility | Fits when |
|---|---|---|---|
| Line on the rental | You: credit, debt, equity | Revolving, mostly drawn at closing | Individual title, keep first mortgage |
| Line on your primary home | You: credit, debt, equity | Revolving, structure varies | Rental has little equity left |
| DSCR cash-out refinance | Rent covering the payment | One lump sum at closing | LLC title, high personal debt |
The second row deserves a note. Some investors fund a rental rehab by borrowing against their own residence instead. On a primary residence, the ceiling on this network reaches 90% CLTV, and only with a credit profile of 720 or better. Lines on a primary home can run up to $750,000, and lines above $500,000 carry a 75% CLTV cap and a full appraisal. The tradeoff is that your own home becomes the collateral. The CFPB warns that if you fall behind on a HELOC, you could lose your home. That is a heavier risk than putting a rental on the line.
The third row is the main alternative to weigh against a line on the rental. A cash-out refinance on a rental replaces the first mortgage and pays out equity as a lump sum. On most files in the network, cash-out on a standard rental tops out around 75% LTV, and about 6 months of seasoning is the common expectation. On short-term-rental collateral, cash-out is held to 70% LTV instead.
DSCR is where qualification changes. The loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. Coverage of 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. Credit minimums vary: a 620 floor exists in parts of the network, most programs want around 660, and 700 or better unlocks the strongest leverage tiers. Reserves commonly run about 6 months of PITIA, and they vary by lender, leverage, and loan size. Loan sizes run up to $3,000,000 on standard programs (smaller balances available through select lenders).
One caution applies to both. Clearing 1.00 on DSCR is not the same as positive cash flow. The ratio compares rent to PITIA only, so repairs, vacancy, management, and utilities sit outside it. For a full walkthrough, see Lendmire’s complete DSCR loans guide.
Where the General Rule Breaks
The rule of thumb is that a line fits investors with equity, strong personal credit, and individual title. Several situations flip it.
The property sits in an LLC. The line cannot be written with an LLC on title. Your choices are a vesting change into your own name or revocable trust, or a DSCR cash-out refinance, subject to lender program eligibility. A vesting change can carry its own consequences with your existing mortgage, so check the terms first.
The unit is vacant or mid-rehab. DSCR review usually needs the property rent-ready, with a lease or market rent supporting coverage. A renovation that empties the unit often has to finish first. A line judged on you personally does not depend on current rent, so the timing can fit better. The plan then is to lease the unit and refinance once it is stabilized.
Your personal debt is heavy. An investor with several mortgages and modest personal income can fail the 50% debt-to-income test on a line even with ample equity. The same investor may clear a DSCR cash-out, because that file looks at rent against the payment rather than your overall debt load.
The property has thin cash flow. A line can approve you and still be a poor idea. It adds a floating payment to a property that may have little room for it. During the interest-only draw period the payment looks manageable. When the 25-year amortizing payment starts, it can jump.
The first mortgage is worth keeping. A cash-out refinance reprices the entire first-mortgage balance. A line adds new borrowing only on what you draw, and it leaves the existing first mortgage in place. If that first mortgage carries terms you could not replace today, a second lien is often the better structure.
The project is huge. A line capped at $500,000 and 70% CLTV may simply not be large enough. Lenders handle this by comparing structures that stack differently, such as a cash-out refinance with extended terms or interest-only periods, which are available through select lenders in the network.
The property is not eligible at all. Manufactured homes, log homes, and barndominiums are not offered on the DSCR side either. If your rental is one of these, neither route applies through this network.
Two further notes on the DSCR side apply to investors comparing paths. Coverage below 1.00 is available through select lenders in the network, with leverage and terms adjusted. No-ratio structures exist only through select lenders, generally for borrowers who already own a primary residence.
Is a HELOC the Right Tool? A Practical Decision Path
Work through these questions in order.
1. Who holds title today? If an LLC does, a line is off the table until title changes.
2. How much room is left under 70% CLTV? If the room is thin, the line cannot carry a major project.
3. Can you carry the payment through vacancy? If not, size the project smaller or sequence it in phases.
4. Is your personal debt-to-income comfortable? If you carry many mortgages, check a DSCR cash-out first.
5. What is the exit? Decide whether you will refinance or pay down the balance before repayment begins, and write the date down.
Keep renovation draws clearly separated from any personal spending on the line. Mixed draws make your records harder to read.

Frequently Asked Questions
Can you get a HELOC on an investment property at all?
Yes, but fewer lenders write them and the terms are tighter than on a primary home. On this network, an investment line runs up to $500,000 at a 70% CLTV ceiling with a 700 minimum score. The lender reviews you personally, so title, credit, and debt all matter.
Why is a rental line harder to get than a primary-home line?
Lenders see more risk when the collateral is a rental. The ceiling is lower, at 70% CLTV on an investment property versus up to 90% on a primary residence, and the 90% figure requires a 720-or-better profile. The credit minimum is higher too, at 700 on an investment line.
Does the after-renovation value count toward the line?
No. The line is sized on the property’s current value, usually through an automated valuation. A higher value after the work may support a larger line or refinance later, depending on comps and underwriter review, but it cannot pay for the project up front.
Can I use a line on my own home to fund a rental rehab?
Yes, many investors do, and it can free up more leverage than the rental allows. The tradeoff is that your residence becomes the collateral. On a primary residence, the network’s CLTV ceiling reaches 90%, only at a credit profile of 720 or better, and the line is subject to lender guidelines.
What if my rental is held in an LLC?
A HELOC on this network cannot be written with an LLC on title. You would either move the property into your own name or trust, or look at a DSCR cash-out refinance, subject to program terms. Each path has trade-offs, so compare them before changing title.
