The Quick Read: No lender sells a no-down-payment short-term rental HELOC. Investors reach that outcome by borrowing against equity in a home or rental they already own, then using the cash as the down payment on the new property, which is still reviewed under its own loan rules.
- The line is usually secured by your primary home, because fewer lenders will place a line on a rental.
- On Lendmire’s wholesale network, a line secured by an investment property tops out at 70% CLTV (combined loan-to-value) and $500,000, with a 700 credit minimum.
- The new short-term rental still needs its own purchase loan, its own reserves, and a paper trail for the borrowed funds.
- Borrowed down payments stack payments on two properties, so the risk moves to your personal balance sheet.
The Setup: What Does No Down Payment Actually Mean?
It means no cash from your savings goes into the down payment. It does not mean no cash at all. The equity line supplies the down payment, and the purchase lender still treats that money as yours.
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.
Investors tend to picture the HELOC as a cash purchase tool. The new property then carries one mortgage, plus the personal payment on the line. That is a near-100% financed deal in practice.
Here is the catch. If borrowed money funds the whole deal, you hold no equity cushion in the new property on day one. Investors discussing this in a BiggerPockets thread on using a HELOC for a down payment or full purchase land on the same test. The new property has to carry its own mortgage and the line payment, and you need a plan to pay the line back.
On a short-term rental, that test is harder than it sounds. Nightly revenue swings with the season. A line payment does not.
The idea is a funding structure, not a program. Lendmire is a broker, so it arranges both halves through select wholesale partners: the equity line and the purchase loan. Each half has its own rules.
Key Terms Defined
HELOC: A home equity line of credit is a revolving credit line secured by a property, with a draw period followed by repayment.
CLTV: Combined loan-to-value adds every lien on the property, including the line, and divides by the property’s value.
DSCR: Debt service coverage ratio is the property’s monthly rent divided by its monthly PITIA (principal, interest, taxes, insurance, and any HOA dues).
Seasoning: The time a borrower has held a property or funds before a lender counts them.
Source of funds: The paper trail showing where down payment money came from.
The Mechanics, Step by Step
Two different transactions share the name HELOC for a short-term rental. They have different collateral, different risk, and different lender pools.
| Factor | Line on your primary home | Line on a rental you own |
|---|---|---|
| Collateral at risk | Your own home | The rental |
| Lender pool | Wider | Thinner |
| Underwriting focus | You: credit, income, DTI | You, not bookings |
| Title | Individual or revocable trust | Individual or revocable trust |
NerdWallet’s explainer on HELOCs for investment property notes that not every lender offers a rental line. It also says lenders see higher default risk on a rental and often charge more. A market guide at RentalRealEstate.com adds that the primary-home route is the most common one, while a line placed directly on a rental comes from fewer lenders with stricter requirements.
Step 1: Size the line. The formula is simple. Take the property’s value, multiply by the CLTV ceiling, subtract every existing lien, then apply the dollar cap.
On Lendmire’s network, an investment property caps at 70% CLTV and a $500,000 line. There is no tier above that for rentals. Primary-residence and second-home lines can reach 90% CLTV, but only at a 720 or better credit profile.
Consider a rental with a first mortgage equal to 40% of its value. Under a 70% ceiling, that leaves roughly 30 points of value to borrow against, before the dollar cap. A primary home with a first mortgage at 60% of value, at 720 or better, leaves up to 30 points under the 90% ceiling. The two plans look similar on paper, but they put very different collateral behind the bet.
Step 2: Check the title. On the network’s lines, the property must sit in your name or in a revocable living trust. An LLC, corporation, or partnership cannot hold title. Irrevocable, blind, and land trusts cannot either.
If your rental already sits in an LLC, you have three real options. You can change the vesting, which can create due-on-sale and liability issues. You can draw against a property you hold personally. Or you can use a DSCR cash-out refinance that keeps the LLC in place, subject to lender program eligibility. That last route replaces the whole balance rather than adding a second lien.
Step 3: Learn the line’s structure. Investment lines on the network run a 5-year interest-only draw, then a 25-year repayment (Tennessee shortens both). At least 75% of the line is drawn at closing. Pricing floats and never converts to fixed. Market guides describe a typical 10-year draw followed by repayment of up to about 20 years, so the network structure is shorter on the draw and longer on repayment.
The 75% draw rule matters for this strategy. It behaves like a funded second mortgage, not a reusable credit card. You start paying on most of the line right away, even if the purchase is still being negotiated.
Step 4: Understand the valuation. Lines up to $500,000 ordinarily use an automated valuation, so a traditional appraisal is uncommon. A rental line caps at $500,000, so it nearly always falls in that lane. A borrower can still request a full appraisal.
Step 5: Meet the personal tests. The line qualifies you, not the property. Expect a 700 credit minimum on an investment line, a 50% maximum DTI, and a check that no more than 15 financed properties sit in your name. Eligible collateral includes one- to four-unit properties, PUDs, townhomes, and condos. Manufactured homes, log homes, and commercial or mixed-use properties are not offered.
HELOC availability is narrower than DSCR availability. The line programs run in 16 states, while Lendmire’s DSCR investor loans cover 41 markets, including Washington, D.C. All figures are subject to lender guidelines and full file review.
Step 6: Draw and move the cash. Once the line is open, the cash goes toward the short-term rental’s down payment. This is where the purchase lender takes over.
How the Purchase Loan Treats the Borrowed Money
The HELOC and the DSCR purchase loan answer different questions. The HELOC asks whether you can carry the debt. The DSCR loan asks whether the property can. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines.
For a short-term rental purchase, most programs in the network top out at 75% LTV, which means about 25% down at minimum. Refinances on a short-term rental run around 70%, and cash-out refinances on short-term rental collateral cap at 70%. Standard long-term rentals reach 75% on cash-out in the same network. Select programs reach 85% LTV on standard purchases at roughly a 700+ score, but that tier does not apply to short-term rentals.
Short-term rental files typically want a 640 or better score. They also want about 12 months of hosting history, shown through trailing platform statements from sites like Airbnb or VRBO. Some files substitute a market-data report where there is no lease. On a purchase, select programs start at 1.00 coverage. Refinance files are reviewed on their own coverage test, which also starts at 1.00 on select programs.
One more point on coverage. 1.00 is where many select programs start. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Neither path equals cash flow, because DSCR compares rent to PITIA only. Repairs, vacancy, management, utilities, furnishing, and capital costs all sit outside the calculation.
Standard appraisal rent schedules, such as Form 1007, rest on monthly comparables, not nightly revenue. That is one reason short-term rental files lean on platform history instead.
Three rules matter most when HELOC cash feeds the purchase.
- The loan keeps its own tier. Credit, leverage caps, reserves, and property eligibility all still apply. A bigger down payment can lift coverage by lowering the payment, but it never erases those limits.
- Reserves vary. Many files want about six months of PITIA. Conservative rate-term files at modest leverage under $1,500,000 can see reserves waived. Loans above that size typically step up to about nine months. Whether borrowed HELOC funds count toward reserves differs from lender to lender, so confirm it before relying on it.
- The money needs a paper trail. Lenders ask where down payment funds came from, and waiting periods differ from bank to bank. A BiggerPockets discussion on buying with a HELOC shows how much that varies in practice.
A HELOC payment tied to a different property generally does not enter the target property’s coverage ratio. It does show up in your personal debt picture, and it affects any later application that looks at DTI.
For how the loan side fits together, the complete DSCR loans guide covers the full program range.
What Can Go Wrong
The risk of this strategy is stacked payments, floating pricing, and thin cushions. Most of the damage shows up in the first slow season.
Payment shock. The CFPB’s HELOC overview says HELOCs usually carry a variable rate, and that payments are often significantly higher once the draw period ends. Its HELOC booklet adds that some plans are interest-only during the draw, and that the payment can change even if you borrow nothing more. On Lendmire’s network, the line floats during both the draw and the repayment period. Interest-only payments become fully amortizing payments in year six on an investment line.
Seasonal revenue against fixed obligations. A short-term rental can post strong peak months and weak shoulder months. The mortgage and the line payment arrive every month either way. A file can clear the DSCR test and still leave you feeding the property from your own income.
Your home becomes collateral. On the primary-home route, a miss on the rental can put your residence behind the bet. That is a different risk profile from a loan secured by the rental itself.
Stacking limits. Each new loan appears on your personal credit report and in your DTI. Investors who use lines for several down payments tend to hit the 50% DTI ceiling. A BiggerPockets thread on a HELOC against a primary residence describes that wall, and it also notes the double closing costs when a purchase is followed by a refinance exit.
Local rules. An income plan that a local rule disallows undermines both the purchase loan and the line.
Costs outside the loan. Furnishing, setup, closing costs, and reserves all need cash. A funded down payment does not cover them.
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.
HELOC, DSCR Cash-Out, or Savings: A Decision Table
Which route fits depends on who holds title, where the equity sits, and whether personal debt capacity is the binding limit.
| Route | Best for | Main catch |
|---|---|---|
| HELOC on primary home | Strong personal credit, modest cash need | Home is at risk |
| HELOC on a rental | Individual title, equity in a rental | 70% CLTV, thin lender pool |
| DSCR cash-out refinance | LLC-held rentals, lump-sum need | Replaces the whole balance |
| Savings as down payment | Anyone with liquid cash | Ties up capital |
The cash-out route replaces your first mortgage and reprices all of it. A HELOC adds a second lien and leaves the first mortgage alone. That difference matters most when an existing first mortgage is cheap.
Who This Fits (And Who It Doesn’t)
It tends to fit an investor who holds title personally or in a revocable trust. It also suits one with a 700-plus score, comfortable DTI room, and meaningful equity in a home or rental. The investor in this profile has the short-term rental’s numbers pencilled with room, not just clearing 1.00. A planned exit, such as paying the line down from cash flow or from a later refinance, also helps.
It tends not to fit an investor whose rentals sit in LLCs and who wants the liability wall intact. It is a poor match for someone already near DTI limits or relying on one property’s peak-season revenue to cover both payments. It also fails the investor with no hosting history who is counting on projected income to carry two loans. If the plan only works with the line funding every dollar, that is a signal to revisit the deal, not the loan type.
None of this is a recommendation. It is a map of where the strategy tends to hold and where it tends to break.
Next Step
If you are considering a home equity line and want to see how the numbers work, Lendmire can help you compare HELOC options based on the property, the equity available, credit profile, combined leverage, and your goals. The brokerage arranges both the line and the DSCR purchase through its wholesale network, and every file is reviewed by the lender subject to its guidelines. This is not a commitment to lend.

Frequently Asked Questions
Can I buy a short-term rental with a HELOC and put nothing down?
Not literally. The HELOC supplies the down payment, but you owe that money back on a separate payment. The DSCR purchase loan still reviews your reserves, your credit, and the source of the funds. On a short-term rental purchase, most programs top out at 75% LTV, so the borrowed money covers the gap above that.
Can an LLC take out an investment property HELOC?
Not on this network. Title must sit with an individual or a revocable living trust, and an LLC, corporation, or partnership cannot hold it. Investors with LLC-held rentals typically look at a DSCR cash-out refinance instead, subject to program terms, or draw on a property they own personally.
Does a HELOC on my rental use Airbnb income to qualify?
No. The line is underwritten on you, using credit, income, DTI, and equity, not on bookings. DSCR is the product that is reviewed on property income, and it uses trailing platform statements or a market-data report for short-term rentals.
How much can I borrow against a rental I own?
The formula is property value times 70% CLTV, minus all existing liens, capped at $500,000. The line must be at least $25,000. A paid-off rental removes the first lien but not the 70% cap.
What happens when the draw period ends?
The line moves into repayment, and the payment steps up because principal is added to interest. On an investment line, a 5-year interest-only draw gives way to a 25-year repayment, except in Tennessee, where both periods are shorter. The pricing keeps floating, so the payment can still change.
Investors focused on short-term rentals can review DSCR loans for Airbnb and short-term rentals.
