Investment Property HELOC vs Cash-Out Refinance as a Down Payment on Another Property

The Quick Read: A home equity line of credit (HELOC) on a rental you already own keeps your first mortgage in place and lets you draw as needed, but it carries lower leverage caps and strict ownership rules. A cash-out refinance replaces the loan, reaches higher leverage, and qualifies primarily on the property’s rental income, subject to lender guidelines.

• On an investment property, the wholesale network Lendmire works through caps a HELOC at 70% CLTV with a maximum line of $500,000. A DSCR cash-out refinance on a standard rental generally reaches higher leverage, with the exact cap depending on the program and the borrower’s profile.
• An investment line must be held by an individual or a revocable living trust. That one rule often decides the whole comparison.
• Whether either source of cash counts as a down payment is up to the purchase lender. Expect a paper trail either way.
• Neither product removes the rental-coverage test on the property you are buying.

The honest answer on who each option is for: the HELOC suits an investor who owns the rental personally, has strong credit and income, wants to leave a good first mortgage alone, and needs a moderate amount of cash. The cash-out refinance suits an investor who needs a larger sum, holds the property in an LLC, or would rather be judged on the property’s rent than on personal debt-to-income.

Lendmire is a mortgage broker. It arranges both products through select wholesale partners and is never the lender. The HELOC side is available in a narrower set of states (16 full-service states) than the DSCR footprint of 41 markets, including Washington, D.C.

Key Terms Defined

CLTV (combined loan-to-value): All loans against the property, added together and divided by its value. A first mortgage plus a HELOC both count.

DSCR (debt service coverage ratio): Monthly rent divided by the full monthly housing obligation on the property. Lenders use it to judge whether the rent supports the loan.

PITIA: Principal, interest, taxes, insurance, and any association dues. It is the full monthly obligation that DSCR measures rent against.

Seasoning: The waiting period a lender wants after you buy a property before it will refinance it.

Draw period: The stretch when you can borrow from a line. Payments are often interest-only during it, and full repayment follows.

Side-by-Side

The table below uses Lendmire’s wholesale network figures for both products. Each figure is a typical range, subject to lender guidelines and full file review.

Three details sit behind that table. First, a HELOC on a rental is judged mainly on you. The network uses a 50% maximum debt-to-income ratio (DTI), which compares your monthly debts to your income. It calculates DTI on the interest-only payment at the maximum draw. Second, an investment line up to $500,000 usually runs on an automated valuation rather than a traditional appraisal. Third, a cash-out refinance on a standard rental is judged mainly on the property. Rent has to cover the new, larger payment, and 1.00 is where many select programs start. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted.

When the HELOC Is the Better Fit

A HELOC fits best when you own the rental personally, your credit is 700 or better, and the cash need is moderate relative to the equity. It also fits when your existing first mortgage is worth protecting. Your first mortgage stays untouched, and nothing resets on the debt you already carry.

The White Coat Investor notes that fewer lenders offer HELOCs on investment property than on a primary home. On the Lendmire network, an investment line stops at 70% CLTV. The investment table has only two tiers. Both 720 and 700 reach 70%, so a higher score buys eligibility, not extra leverage.

Here are the situations where the HELOC tends to make sense:

• Personal title and a clean first mortgage. You hold the rental in your own name or a revocable trust, and the existing first mortgage is one you want to keep.
• A smaller cash need. The line tops out at $500,000 on an investment property, and the amount you can reach depends on how much of the value is already pledged.
• A strong personal profile. You can carry a DTI up to 50% and the credit history to match.
• A property that fits the program. Single-family homes, 2-4 units, PUDs, townhomes, and condos, including non-warrantable ones, are eligible. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural zoning are not.

Know what the structure does to flexibility. At least 75% of the line is drawn at closing, and the pricing floats through both the draw and repayment periods without ever converting to fixed. The “draw only what you need” appeal is therefore smaller than it sounds when the goal is a one-time down payment. Most of the line is already borrowed on day one.

The exposure limits matter for portfolio investors. A borrower can hold at most three lines, combined exposure is capped by program, and a borrower with more than 15 financed properties is not eligible.

When the Cash-Out Refinance Is the Better Fit

A cash-out refinance is the better fit when you need a large sum, hold the rental in an LLC, or would rather qualify on the property than on your personal income. It also fits when the rental has built up substantial equity and the existing mortgage has no features worth protecting.

LLC-titled rentals may be eligible for a cash-out refinance, subject to lender program eligibility. A HELOC cannot go on a property deeded to an LLC, a corporation, a partnership, or an irrevocable, blind, or land trust. A rental already in an LLC needs a vesting change before a HELOC is possible. A DSCR cash-out avoids that detour.

Consider what else the cash-out brings:

• Higher leverage. Most of the network tops out around 75% LTV on a standard rental. On short-term-rental collateral, cash-out is held to about 70%. That leaves more usable equity than a 70% CLTV investment line.
• Larger loan sizes. Loans run up to $3,000,000 on standard programs (smaller balances available through select lenders). Above $2,500,000 the network generally holds to 30-year fixed structures.
• Seasoned, documentable cash. Proceeds arrive as a lump sum in your account, which is easier to trace than draws from an open line.
• Structure choices. The spine is the 30-year fixed. Select lenders in the network offer extended 40-year terms and interest-only periods, and ARM structures exist for investors who want them.
• Wider property eligibility. The one carve-out is that manufactured homes, log homes, and barndominiums are not offered in these DSCR programs.

The trade-offs are real. About six months of seasoning is the common expectation, so a recent purchase may have to wait. The whole first mortgage is replaced, and closing costs apply to the entire new balance. Reserves are commonly around 6 months of PITIA, though they vary by lender, leverage, loan size, and transaction type. Conservative rate-term files at modest leverage under $1,500,000 can see reserves waived, and larger loans typically step up to about 9 months.

DSCR looks at rent against PITIA only. Clearing 1.00 does not mean positive cash flow. Repairs, vacancy, management, utilities, and capital expenses sit outside the calculation, so a thin ratio on the old rental deserves a hard look before you enlarge its debt.

Can Borrowed Equity Count as a Down Payment?

It can, but the purchase lender makes that call. Lenders generally set their own policies on borrowed funds, and DSCR lenders are no exception.

For contrast, Fannie Mae’s Selling FAQ treats funds borrowed against an asset as an acceptable source for down payment, closing costs, and reserves. It also lists a HELOC on another property as a documentable source. That is an agency rule, and DSCR loans are not agency products. Treat it as a reason the practice is common, not as a promise that a given lender will follow it.

Plan the file around three questions the purchase lender is likely to ask:

1. Where did the cash come from? A seasoned lump sum from a cash-out refinance is straightforward to trace. A fresh draw from a new line shows up as new debt.

2. Does the new payment count as a liability? The lender may review a new HELOC payment against your overall profile.

3. Is there enough left over? Down payment money and reserves are separate tests, and lenders look at both.

Select programs reach 85% LTV (15% down) with roughly a 700+ score. A larger down payment lowers the monthly obligation and can lift the DSCR. It does not erase leverage caps, credit floors, reserve rules, or property eligibility. The strongest files have enough equity and enough rental coverage.

Running the Percentages on Both Routes

The cleanest way to compare is in percentages of value. These are modeled assumptions, not market data.

Say you own a rental with a first mortgage equal to 40% of its value. You want to buy a new rental at 75% LTV, so you need 25% of the new purchase price as a down payment. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.

• HELOC route. A 70% CLTV ceiling leaves 30% of the old rental’s value available at most, before the $500,000 line cap. To cover a 25% down payment, the old rental needs to be worth roughly 0.83 times the new purchase price or more.
• Cash-out route. A 75% LTV ceiling on a standard rental leaves 35% of value, before closing costs. The old rental needs to be worth roughly 0.71 times the new purchase price or more.

That gap is why larger purchases often push investors toward cash-out. A cash-out also puts the extra debt into the old rental’s first mortgage. If that rental’s rent only barely covers its current payment, the larger loan can push its coverage ratio under 1.00. On a HELOC, the old rental’s rent is not tested against the new line the way a DSCR cash-out tests it. The line shows up in your personal debt-to-income instead. The two products shift the stress test to different places.

Lendmire’s piece DSCR HELOC vs DSCR Cash-Out Refinance Draw as a Documented Rental Down Payment goes deeper on the documentation side.

What Can Go Wrong With Either Route

Both options turn equity into debt, and each has a failure mode.

The CFPB’s HELOC brochure describes a HELOC as open-end credit with a draw period followed by a repayment period. Payments during the draw can be interest-only, and the payment can change even if you borrow nothing more. It also warns that failing to repay can cost you the home that secures the line. When the draw ends and the payment starts to amortize, the monthly outlay can jump while the new property is still being renovated or leased up.

Cash-out has its own risk. The new loan is larger, the whole balance is repriced, and a thin cushion on the old rental gets thinner. Compare your existing first mortgage with the replacement before you give it up.

Another route is a HELOC on your own home instead of the rental. On the network, primary-residence and second-home lines can reach 90% CLTV, and only at a 720 or better credit profile. That moves the lien and the risk onto the place you live. The CFPB’s warning about losing the home applies with full force.

A HELOC cannot be reduced to a formula the way a DSCR loan can. A line can also be frozen or trimmed if your credit or finances deteriorate, so check the line’s terms before you rely on it as a standing source of down payments. Credit reports must be no more than 90 days old at closing, and the network does not rescore.

Which One Should You Pick?

The choice usually comes down to title, size, and how much you want your personal finances in the picture.

• Pick the HELOC if you hold title personally, have 700+ credit and low personal debt, need a moderate amount, and want your first mortgage untouched.
• Pick the cash-out if you hold the rental in an LLC, need more than the 70% CLTV ceiling allows, or want the property’s rent to carry the qualification.
• Consider neither if the rental is thin on coverage. Adding debt to a property that barely covers itself rarely improves a portfolio.

A middle path exists for some investors. A modest HELOC can cover a smaller down payment, and a cash-out can follow once the new property has aged enough for its own refinance. Sequencing matters, because each step changes the numbers the next lender sees.
