The Quick Read: Not every lender writes a home equity line on a rental, and each sets its own rules. On the wholesale network Lendmire works with, an investment line is sized by equity (70% combined loan-to-value), not by the cost of the deck. Which lenders write it depends on your credit, the property, and how you hold title.
- Large retail banks often focus on owner-occupied homes, so a rental owner may need to look across lender types.
- On an investment property, the network ceiling is 70% combined loan-to-value, with a 700 credit minimum and a $500,000 maximum line.
- A deck budget matters only if it exceeds the room your equity leaves.
- An LLC cannot hold title on these lines, so a property already deeded to an LLC needs a different route.
- When the property is out of reach for a line, a DSCR cash-out refinance is the usual alternative for a rental.
What Is an Investment Property HELOC?
A HELOC (home equity line of credit) is a revolving credit line secured by a property you already own. On a rental, the lender takes a lien on the investment property. That lien usually sits behind your first mortgage, though on this network the line can sit in first or second position.
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.
You borrow from the line as you need it, up to the limit. An investment-property line on this network runs a 5-year interest-only draw period, then a 25-year repayment period where principal and interest are both due. Pricing on this program floats across both periods and never converts to fixed.
The structure fits a deck because a deck is a one-time capital project. You pay a contractor, you stop drawing, and you pay the balance down. A DSCR loan works differently. It is a first-lien purchase or refinance that qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. The two products solve different problems, which the complete DSCR loans guide explains in more depth.
Which Types of Banks Offer One?
No single bank type is a sure answer, and availability changes by lender and over time. This table sorts lenders by category, not by name, so you know where to start looking.
| Lender type | Typical fit | Where to start |
|---|---|---|
| Large retail banks | Usually owner-occupied homes only | Ask if non-owner-occupied lines exist |
| Regional and community banks | More flexible for local relationships | Your existing deposit bank |
| Credit unions | Case-by-case, often member-based | Credit union where you hold accounts |
| Online lenders | Standardized, automated review | Compare eligibility screens first |
| Wholesale network via a broker | Many programs screened at once | A broker matched to your scenario |
NerdWallet notes that not every lender offers a HELOC on an investment property and that qualification requirements are strict. It also reports that lenders treat default risk as higher than on a primary home. On the Lendmire network, an investment line requires a 700 minimum credit profile and reaches 70% combined loan-to-value.
A broker earns its place here because the lenders that write this product vary so much. Lendmire is a mortgage broker, not a lender. It places files with select wholesale HELOC lenders and matches the scenario to the program whose guidelines fit. The best program for your situation depends on your credit, equity, property type, and vesting.
Why So Few Lenders Write These
A second lien on a rental sits behind the first mortgage. If the borrower stops paying, the second lender collects only after the first lender is made whole. A tenant-occupied property adds another layer of uncertainty, because the owner’s own housing is not at stake. Many retail banks decide the risk is not worth the product.
Some lenders also restrict by location or by how the home is used. That is why a short call to the lender’s loan desk beats reading its website.
How Underwriting Treats a Deck Line, Step by Step
Underwriting of an investment line follows a predictable path. Here is the sequence on the programs the brokerage places files with.
1. Property and title screen. The lender confirms the property type and who holds title. Single-family homes, 2-4 unit properties, PUDs, townhomes, and condominiums (including non-warrantable condos) are eligible. Title must sit with you as an individual or in a revocable living trust.
2. Credit review. A 700 credit profile is the floor on an investment line. The lender uses a single-bureau score keyed to the primary wage earner, and the report can be no more than 90 days old at closing. A bankruptcy needs 4 years of seasoning from discharge or dismissal. A foreclosure history follows a 7-year path, and a deed-in-lieu, pre-foreclosure, or short sale follows 4 years.
3. Debt-to-income check. The ceiling is 50% DTI. The lender reviews your file on the interest-only payment calculated on the maximum draw, not on what you plan to borrow.
4. Equity test. The lender totals your first mortgage and the new line, then divides by the property’s value. On an investment property, the total cannot exceed 70% of value.
5. Valuation. Because an investment line tops out at $500,000, and full appraisals are required only on lines above that amount, it normally runs on an automated valuation with no traditional appraisal. You may request a full appraisal in any case.
6. Closing and first draw. At least 75% of the line is drawn at closing. After that, a subsequent draw typically has a $1,000 minimum.
Exposure limits can also stop a file. A borrower is limited to three lines in total. Combined exposure across those lines is capped at $2,000,000 on the higher-leverage program and $750,000 on the longer-runway program. A borrower who owns more than 15 financed properties is not eligible. Every figure here is subject to lender guidelines and full file review, and none of it is a commitment to lend.
Worked Example: Sizing the Line From Equity
The line is sized from equity, not from the deck budget. The calculation is simple. Take the 70% ceiling, then subtract your first mortgage as a share of value.
Say your first mortgage sits at 50% of the property’s value. That leaves 20 points of value available under the 70% ceiling. A deck is a small project, so it fits easily inside that room.
Now say your first mortgage sits at 68% of value. Only 2 points remain, and a line sized to the minimum cannot fit regardless of how modest the deck is. A highly leveraged rental may have no room at all.
The automated valuation matters too. Such a model will not credit a deck you build after the valuation date. The line is sized on the pre-deck value. Once the deck is done, an improvement may support a higher appraised value, depending on comps and underwriter review, but you should not borrow against that increase today.
Two program features shape small projects specifically. The minimum line is $25,000. A basic deck can cost less than that, which means you would be borrowing more than the project needs. And because at least 75% of the line is drawn at closing, you start paying interest on most of the line immediately. For a very small deck, cash or another tool may fit better.
Deck-Specific Planning
A deck is a capital improvement, which means a permanent addition to the property, not a repair. That distinction matters for your bookkeeping.
Before you apply, scope the project in four steps:
- Get written quotes. Compare at least two contractors and keep the scope in writing, so the draw matches the invoice.
- Check the permit. A deck is built out structurally, and your local building department decides what permit applies. Unpermitted work can complicate a later sale or insurance claim.
- Read the use clause. Nothing in the program structure restricts a deck, but the line agreement controls how you may spend the draw. Read it before you sign.
- Test the payback. A deck rarely returns its full cost at resale, and resale value is not rental income. Ask whether it keeps a good tenant longer or supports a higher rent in your local comps before you count on either.
Some investors prefer a patio instead. A patio can need less structural work, less permitting, and less ongoing maintenance, and it often serves a similar purpose. That is a value-add opinion, not a lending rule, but it is worth pricing both.
How the Draw and Repayment Phases Work
Everything about repayment comes from the contract, so the structure matters more than the label. The CFPB’s HELOC brochure explains that during the draw period you can generally spend up to your credit limit whenever you want. After that, you enter a repayment period. If the plan has a variable interest rate, payments can change even if you draw nothing more.
Interest-only payments during the draw period feel light. The payment steps up when repayment starts, because principal joins the bill. On this network, that step comes after year five, and the payoff stretches across 25 years. Investors who treat a HELOC as short-term money, paid down soon after the work is done, avoid most of that shock.
Where the General Rule Breaks
Several situations change the answer for a deck loan.
Title in an LLC. This is the sharpest difference from a DSCR loan. 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 first, or a DSCR cash-out refinance instead. The vesting change carries its own consequences, so talk to your attorney before you move title.
Ineligible property types. Manufactured homes, co-ops, condotels, log homes, commercial properties, mixed-use properties, and agricultural-zoned properties are not offered on these lines. If your rental is one of them, this route is closed.
Thin equity. If your first mortgage already uses most of the 70% ceiling, no line is available, no matter how small the deck.
Limits on state and listing status. The line is available only in Lendmire’s 16 full-service states (AL, CA, CO, FL, GA, IN, MI, MT, NM, NC, OH, PA, TN, TX, VA, WA). A property listed for sale, or listed within the past 60 days, is ineligible in several of those states.
Over-leveraged portfolios. An investor who owns more than 15 financed properties is not eligible, and the three-line cap can stop a fourth line even with plenty of equity.
Recent purchases and refinances. A property you just bought or refinanced raises questions about value and seasoning. Ask the lender about any waiting period before you plan the build.
A low valuation. If the automated valuation comes in below your own estimate, the lender can shrink the line. A second opinion does not guarantee a higher number.
When a DSCR Cash-Out Refinance Fits Better
If the rental does not fit a line, the usual alternative is a DSCR cash-out refinance. It replaces your first mortgage with a new loan and pays you the extra equity, and the whole file is reviewed on the property’s rent.
Here is how the DSCR route looks across the network, as typical ranges rather than guarantees:
- Leverage: A cash-out refinance on a standard rental tops out around 75% LTV. Short-term rental collateral on a cash-out refinance tops out at 70%.
- Seasoning: About 6 months of ownership is the common expectation before a cash-out.
- Coverage: 1.00 is where many select programs start, and a separate select-lender path takes coverage below 1.00 with leverage and terms adjusted. Stronger ratios open better pricing and leverage.
- Credit: A 620 floor exists in parts of the network. Most programs want around 660, and 700 or more unlocks the strongest leverage tiers.
- Loan size: up to $3,000,000 on standard programs (smaller balances available through select lenders).
- Reserves: Commonly around 6 months of PITIA, which is principal, interest, taxes, insurance, and any HOA dues. Reserves vary by lender, leverage, loan size, and transaction type.
The tradeoff is that a cash-out refinance resets your whole first mortgage for a deck-sized need. That is a heavy move if your existing loan has terms you want to keep. It makes more sense when the deck is one piece of a larger plan.
Clearing a coverage ratio of 1.00 does not mean positive cash flow. DSCR compares rent to PITIA only. Repairs, vacancy, management, utilities, and capital spending sit outside the calculation.
A line on the subject property also adds a second debt to the file. Any later DSCR refinance has to account for it, and the line gets paid off or subordinated at that point. A larger down payment on a future purchase can lift coverage, but it never erases leverage caps, credit floors, reserve rules, or property eligibility.
What the Decision Looks Like in Practice
For most rental owners, the choice comes down to three paths.
| Path | Best when | Main tradeoff |
|---|---|---|
| Line on the rental | Equity room, individual title | 700 credit, 70% CLTV cap |
| Line on your primary home | Strong equity at home | Your residence secures it |
| DSCR cash-out refinance | Rental has strong coverage | Replaces your first mortgage |
A line on your primary home reaches higher combined leverage than a rental line. On this network, primary and second-home lines reach up to 90% CLTV, and only at a 720 or better credit profile. The cost is that your own home secures the deck project on your rental.
Compare the investment-property line against the primary-home line on this network:
| Factor | Investment line | Primary-home line |
|---|---|---|
| Max combined LTV | 70% | Up to 90% at 720+ |
| Minimum credit | 700 | 600 program floor |
| Maximum line | $500,000 | $750,000 |
| Draw structure | 5-year draw, 25-year repay | 3/17 or 5/25 |
Before you commit to any lender, ask these questions:
- Do you write lines on non-owner-occupied 1-4 unit properties?
- Will you accept my vesting, individual or revocable trust?
- Is the valuation automated, and can I request a full appraisal?
- What is the minimum line, and how much must I draw at closing?
- How does the payment change when the draw period ends?
Key Terms Defined
HELOC: A revolving credit line secured by a property you own, with a draw period followed by a repayment period.
Combined loan-to-value (CLTV): The total of all liens on the property divided by its value.
Draw period: The stretch when you can borrow from the line and typically pay interest only.
Repayment period: The stretch after the draw ends when principal and interest are both due.
Automated valuation: A computer-model estimate of value used instead of a full appraisal.
Capital improvement: A permanent addition, like a deck, that is treated differently from a repair.
PITIA: Principal, interest, taxes, insurance, and any association dues, which is the payment a DSCR calculation measures.
DSCR: Debt service coverage ratio, meaning the rent divided by the monthly obligation on the property.
Frequently Asked Questions
Can I get a HELOC on a rental property?
Sometimes. Many retail banks restrict lines to owner-occupied homes, so availability depends on the lender. On the network the brokerage uses, an investment line needs a 700 credit profile, reaches 70% combined loan-to-value, and caps at $500,000. Title must sit with an individual or a revocable trust, subject to lender guidelines.
Will the new deck increase how much I can borrow?
Not on the first line. Investment lines normally use an automated valuation, which will not credit a deck built after the valuation date. The deck may support a higher appraised value later, depending on comps and underwriter review.
Does a line count against my DSCR on a later refinance?
A later DSCR refinance has to account for any second lien on the property. The refinance typically pays off or subordinates the line. Plan for that before you borrow, because the combined leverage affects the loan you can get.
Can my LLC take out a HELOC on its rental?
No. A property already in an LLC needs a vesting change first, or a DSCR cash-out refinance instead.
Is a patio a better choice than a deck?
It can be, depending on your property. A patio often needs less structural work and less upkeep. The better choice depends on your tenant profile, your local rental comps, and what each option costs to build.
