The Quick Read: How much you can borrow against a short-term rental comes from your equity and your personal finances, not from what the listing earns. On an investment property, the combined loan-to-value ceiling is 70%, the first mortgage comes off the top, and the line stops at $500,000. A HELOC (home equity line of credit) is a revolving credit line secured by the property.
- The ceiling is 70% CLTV on an investment property. CLTV means combined loan-to-value: every loan on the property, added together, measured against its value.
- Borrowing room is value times 70%, minus what you already owe, capped at $500,000.
- You are underwritten, not the rental. Credit, debt load and documented income decide the file. Airbnb income helps only where it is documented and counted.
- Title matters. The home must sit in your name or a revocable living trust. An LLC cannot hold title on this product.
- A DSCR cash-out is the property-qualified alternative. It suits LLC-held and income-heavy portfolios.
What “Borrowing Power” Means on a HELOC
Borrowing power here is the dollar amount of equity a lender will let you draw. It is not a measure of how profitable the rental is. Those are two different questions, and mixing them up is where most investors go wrong.
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.
DSCR stands for debt service coverage ratio: monthly rent divided by the full monthly payment, meaning principal, interest, taxes, insurance and any HOA dues. Across the wholesale network Lendmire works with, select programs start at 1.00 coverage, and stronger ratios open better pricing and leverage. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted.
A HELOC works the other way around. The lender asks whether you, personally, can carry the debt. Your credit, your existing liens and your debt-to-income ratio (DTI, your monthly debts as a share of monthly income) drive the answer.
Why is this product scarce? NerdWallet explains that investment-property borrowers face a smaller pool of lenders and borrow less than against a primary home, because lenders see higher default risk. That is lender appetite, not a legal ban. Big retail lenders often skip the product entirely.
Across our network, a handful of programs will do an investment-property line. They follow the same shape, covered next.
How Underwriting Sizes Your Line, Step by Step
The line size is a subtraction problem with a ceiling on top. Take the property value, multiply by the CLTV limit, subtract every lien already on the property, and cap the result at $500,000. Everything else in the file decides whether you get to use that room at all.
Step 1: The title gate. The property must be held by you as an individual or in an inter vivos revocable living trust. LLCs, corporations and partnerships are out. So are irrevocable, blind and land trusts. Many short-term rental owners hold in an LLC and stop right here.
Step 2: The occupancy class. The lender decides whether the file is a primary residence, second home or investment property before it looks at anything else. That choice sets the CLTV ceiling and the credit floor. A fully rented property is an investment file. A duplex where you live in one unit is treated as a primary residence. Occupancy is decided at application, so describe it accurately.
Step 3: The credit floor. An investment-property line needs a 700 minimum score. A 720 score reaches the same 70% CLTV ceiling as a 700, so higher credit buys eligibility, not extra leverage. The report can be no more than 90 days old at closing.
Step 4: The equity math. Here is the subtraction, on an investment property at the 70% CLTV ceiling:
| First mortgage (% of value) | Most the line can be (% of value) |
|---|---|
| None (paid off) | 70%, then the $500,000 cap applies |
| 50% | 20% |
| 60% | 10% |
| 70% or more | Nothing |
The percentage is a ceiling on total debt, not the size of your line. Many investors read 70% and assume they can borrow 70% of the value. If you already owe half, you can borrow at most another 20%. A paid-off property is the cleanest case. The $500,000 cap then becomes the binding limit on larger properties, and there is no higher investment tier.
Step 5: The DTI test. DTI can run up to 50%. The lender reviews your file on the interest-only payment calculated on the maximum draw, not on what you plan to borrow. A portfolio of mortgaged rentals can raise your DTI and crowd out the line, even with plenty of equity.
Step 6: Valuation. Because an investment line caps at $500,000, it normally runs on an automated valuation model with no traditional appraisal. You can request a full appraisal if you want one.
Step 7: Structure. The investment line has a 5-year interest-only draw period followed by a 25-year fully amortizing repayment period. At least 75% of the line is drawn at closing. Pricing floats the whole way and never converts to fixed.
All of these figures are typical ranges from select wholesale-network guidelines. Each file is reviewed individually, and nothing here is a commitment to lend.
How Lenders Read Short-Term Rental Income
On this product, Airbnb income is a supporting character, not the lead. The HELOC is underwritten to the borrower: credit, existing liens and debt load. Rental income matters only where the file uses it to offset or support your DTI, and lenders vary on that.
Where short-term income is counted, expect a document trail. The file typically calls for filed traditional personal-income documentation, bank statements and mortgage statements on every property you own, then platform records and deposits for the rental itself. Three habits show up in underwriting:
- Net, not gross. Underwriters generally use net income after expenses, not the gross bookings you see on the platform dashboard.
- A discount for swings. Some underwriters haircut short-term income because it moves more than a signed lease does.
- Everything has to reconcile. Manager or platform reports must match the deposits in your bank statements and the income on your return.
Self-employed owners feel this most. Write-offs that shrink your tax bill also shrink the income an underwriter can use. Strong cash flow on the platform and a thin return do not add up to a strong file.
A brand-new listing is a different story on a HELOC than on a DSCR loan. With no hosting history, there is little rental income to document, so the file leans on your personal profile. That can work if your credit, DTI and equity carry it. On a DSCR short-term rental loan, by contrast, lenders typically want about 12 months of hosting history, and a newer listing may underwrite on long-term rent instead.
Owners with several properties, a manager and a platform often have three versions of the same income. Files tend to move more smoothly when those versions are reconciled before anyone asks.
Three Routes Compared
You have three realistic ways to turn short-term rental equity into cash. Each underwrites something different. Pick based on how the property is titled and who is carrying the debt.
| Factor | HELOC on the rental | HELOC on your home | DSCR cash-out |
|---|---|---|---|
| Underwritten on | You | You | The property |
| Collateral | The rental | Your home | The rental |
| Title | Individual or trust | Individual or trust | LLC often workable |
| Existing first loan | Stays in place | Stays in place | Replaced |
| Leverage | 70% CLTV | Up to 90% CLTV at 720+ | 70% on STR collateral |
A few notes on the table. The 70% CLTV figure is for an investment property. The 90% CLTV figure applies only to primary-residence and second-home lines, and only at a 720-or-better credit profile. The DSCR cash-out ceiling is 70% LTV on short-term-rental collateral, versus 75% on standard rentals. LLC-held loans are subject to lender program eligibility. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.
The DSCR route replaces your first mortgage with a new loan. A HELOC leaves it alone. If your existing first mortgage is low-cost and you want to keep it, that favors the HELOC. If the property is in an LLC, or your DTI is already stretched, the DSCR cash-out is usually the better fit. For the broader picture, Lendmire’s complete DSCR loans guide walks through how those loans work.
On STR collateral, select DSCR programs start at 1.00 coverage on both a purchase and a refinance. Purchases run up to 75% LTV. Refinances sit around 70%. Expect a 640+ score and about 12 months of hosting history. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
Keep one trap in mind. Clearing 1.00 compares rent to the payment only. Repairs, vacancy, management fees, utilities and capital expenses all sit outside the calculation. A property can clear the ratio and still lose money.
Where the General Rule Breaks
The rules above hold for most files. These are the named edge cases where they bend or snap.
The LLC-held Airbnb. A property deeded to an LLC cannot take this HELOC. You would need to change the vesting, which has its own consequences, or use a DSCR cash-out instead.
The primary-home line used for a rental. Some investors skip the rental as collateral. One investor described borrowing against a primary-residence house to buy a beach condo as a short-term rental. The ceiling is higher on a primary home, up to 90% CLTV at a 720-or-better profile. The catch is plain: your home becomes the collateral at risk if the rental underperforms. That is a personal decision, not a financing trick.
The house-hack that becomes a rental. Occupancy class is decided at application, based on how you actually use the property. The line is priced and limited for that class. Applying under the wrong one is a compliance problem, not a strategy.
The condotel. Single-family homes, 2-4 units, PUDs, townhomes and condominiums, including non-warrantable condos, are eligible. Condotels are not. Manufactured homes, co-ops, log homes and commercial or mixed-use zoning are also out.
The very large portfolio. A borrower is limited to three lines, with caps on combined exposure. An owner with more than 15 financed properties is not eligible.
The wrong state. This investment-property line is available in 16 states only. That is narrower than Lendmire’s 41-market DSCR footprint, which includes Washington, D.C. Some states add their own limits on listed properties and acreage.
The rental-use clause. The line agreement itself may restrict renting the home, so read it before you sign. Short-term rental rules can vary by city, county, HOA, and property type, so investors should confirm local rules before relying on projected rental income.
The same logic applies if your target is not a HELOC at all. DSCR financing through the network does not cover manufactured homes (single- and double-wide), log homes or barndominiums. Those property types are not offered.
What the Line Does to You (the Risks)
A HELOC is cheap to open and easy to misuse. Three risks deserve a straight look.
Variable pricing. The Consumer Financial Protection Bureau says HELOCs usually carry a variable interest rate, so payments can change from month to month. On this investment line, pricing floats across both phases and never converts to fixed. Some other plans let you lock part of the balance. That option is not part of this product.
The draw-to-repayment shift. The agency’s HELOC brochure describes the same two phases this line uses: a draw period when the line is open, then repayment. Some plans allow interest-only payments during the draw, so nothing goes toward principal. When repayment starts, the balance begins to amortize. A line you treated as cheap money can turn into a heavy monthly bill. Plan the payoff before the draw period ends.
Thin margins. Because at least 75% of the line is drawn at closing, you start paying interest on most of it immediately. Borrowing for a down payment on another rental, then relying on rent to carry it, is the classic way to run out of cushion in a slow season. Short-term income swings with the calendar.
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.
Is a HELOC the right tool for a purchase? Usually not on its own. It is cash, not a purchase loan, so a DSCR loan typically closes the purchase. The line then funds renovations, reserves or the next down payment, within the limits above.
Key Terms Defined
HELOC: A revolving credit line secured by a property, with a draw period followed by a repayment period.
CLTV (combined loan-to-value): All loans on the property, added together, divided by its value.
DTI (debt-to-income ratio): Your monthly debt payments as a share of your monthly income. Here it is qualified on the interest-only payment at the maximum draw.
DSCR (debt service coverage ratio): Monthly rent divided by the full monthly payment (principal, interest, taxes, insurance and HOA dues).
Draw period: The stretch when you can borrow from the line, here 5 years on an investment property.
Vesting: How title to the property is held, such as in your own name, a revocable trust or an LLC.
Non-warrantable condo: A condominium project that does not meet standard project-approval rules. These are eligible on this HELOC.
Deciding in Practice: Which Path Fits
Run through these questions in order. The first “no” usually points to your answer.
1. Is the property titled in your name or a revocable trust? If not, look at a DSCR cash-out, or plan a vesting change.
2. Is your credit at 700 or better? Below that, an investment-property HELOC is off the table.
3. Do you have equity after subtracting your first mortgage at 70% CLTV? If the remaining room is small, the line will not move the needle.
4. Can your DTI absorb the maximum draw? The lender tests the full line, not your planned draw.
5. Do you want to keep your current first mortgage? That favors a HELOC. Replacing it favors a DSCR cash-out.
6. Is the property in an eligible state and an eligible type? Condotels and manufactured homes are out.
A DSCR cash-out is usually the stronger choice for an LLC-held short-term rental. It qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. It also reaches up to 70% LTV on short-term-rental collateral, with a 640+ score and about 12 months of hosting history. A HELOC suits personally titled rentals with strong personal income and meaningful equity.
Before you apply, gather the following. Traditional personal-income documentation, bank statements, mortgage statements on every property, and platform and manager reports that reconcile with your deposits. Then estimate your equity honestly: value, minus liens, against the 70% ceiling.
Frequently Asked Questions
Does a higher Airbnb income raise my HELOC limit?
Generally no. The limit comes from the CLTV ceiling minus your existing liens, capped at $500,000. Income affects whether you qualify on DTI, not how large the line can be. A 720 score reaches the same 70% ceiling as a 700 on an investment property.
Can I get an investment-property HELOC if my Airbnb is in an LLC?
Not on this product. LLCs, corporations, partnerships and irrevocable, blind or land trusts cannot hold title. You would change the vesting to your own name or a revocable trust, or use a DSCR cash-out instead, subject to lender program eligibility.
What is the most I can borrow on an investment property?
The line tops out at $500,000, and there is no larger investment tier. Within that cap, you can borrow only up to 70% of the property’s value minus all existing liens. Primary-residence lines can run larger, but they follow different rules.
Does a brand-new short-term rental qualify?
It can, because the HELOC is underwritten to you rather than to the listing’s track record. Credit, DTI and equity carry the file. A DSCR short-term rental loan is different: lenders typically want about 12 months of hosting history, or they may underwrite on long-term rent.
Is a HELOC or a DSCR cash-out better for a short-term rental?
A HELOC qualifies you, and a DSCR cash-out qualifies the property. A HELOC keeps your existing first mortgage in place. A DSCR cash-out replaces it, accepts LLC title in many cases, and does not run through your personal DTI.
