Cash-Out Refinance for Rental Property Down Payments: Rules, Risks, and Strategy

If you’re looking to buy an investment property in 2026—whether a long-term rental, short-term Airbnb, or multi-unit building—one of the biggest hurdles is coming up with the down payment. With investment property down payments typically ranging from 15% to 25%, the upfront cash requirement can be steep.

One strategy many homeowners use?

A cash-out refinance on their primary residence.

Tapping into your home equity can give you the capital you need to expand your real estate portfolio—without draining your savings or selling other investments.

But is it smart? And what rules should you know before using a cash-out refinance to fund an investment property purchase?

This guide walks you through the benefits, risks, loan requirements, IRS considerations, and how to safely maximize your cash-out.

Key Takeaways

✅ You can use cash-out refinance funds for any legal purpose, including an investment property down payment

✅ You typically need 20% equity left in your primary home after refinancing

✅ Rates on cash-out refinances are often higher than rate-and-term refinances but often cheaper than other borrowing options

✅ Investment properties require 15–25% down, depending on occupancy, credit, and loan type

Can You Use a Cash-Out Refinance for an Investment Property Down Payment?

Yes.

Lenders do NOT restrict how you use cash-out proceeds, and the money doesn’t need to be sourced from your bank account for any special timeframe (unlike inherited funds or gifts). Once the refinance closes, the cash is yours to use for:

• Rental property down payment

• Closing costs

• Renovations on an investment property

• Reserves required by an underwriter

• Paying off debt before applying for the investment loan

There is no IRS penalty, no waiting period, and no documentation requirement regarding the use of the funds.

How Much Cash Can You Pull Out?

Your maximum cash-out amount depends on:

• Your home’s value

• Your current mortgage balance

• Your loan program (Conventional, FHA, VA, Jumbo)

• Lender-specific LTV limits

Typical Cash-Out LTV Limits

Example of Maximum Cash-Out Calculation

• Home value: $650,000

• Max LTV (conventional 80%): $520,000

• Current mortgage balance: $370,000

Estimated cash-out: $150,000 (minus closing costs)

💡 Pro Tip: Lenders price loans differently. Don't lose your good pricing to a 0.25% rate markup that shouldn't exist. After you get a Loan Estimate from your preferred lender, upload it to Fincast to ensure you have a competitive offer (no extra credit pulls needed).

Investment Property Down Payment Requirements

Cash-out funds can be used to meet these down payment minimums:

1️⃣ Single-Family Investment Property

• 20% down most common, but it depends on your borrower profile

2️⃣ Two- to Four-Unit Properties

• Typically, 25% down

3️⃣ Short-Term Rentals (Airbnb, VRBO)

• 20–25% down

• Lenders may require a history of rental income or reserves

4️⃣ DSCR (Debt Service Coverage Ratio) Loans

• 20–25% down

• Approval based on rental income instead of personal income

💡 Pro Tip: Some lenders require 6–12 months of reserves for investment properties. Your cash-out proceeds can often be used for those reserves as well. It’s important to find the most competitive deal for your cash-out refinance to maximize your cash-out.

Why Use a Cash-Out Refinance to Invest in Real Estate?

✔ 1. Unlock Capital Without Selling Assets

You preserve:

• Stocks

• Retirement funds

• Emergency savings

Your home equity works for you without sacrificing liquidity.

✔ 2. Lower Cost of Capital

Compared to:

• Personal loans (10–20%+)

• HELOCs (variable rates)

• Hard money loans (8–12%+)

Cash-out refinances offer:

• Lower fixed rates

• Longer repayment terms

• Predictable monthly payments

💡 Pro Tip: A bad refinance offer can cost you thousands of dollars. Before you sign, verify your pricing is competitive.

✔ 3. Scale a Real Estate Portfolio Faster

Cash-out equity allows you to:

• Buy your first rental

• Buy your second or third rental

• Expand to multi-unit properties

This is how many small investors scale into full portfolios.

✔ 4. Potential Tax Advantages

While the cash-out itself is not deductible, mortgage interest may be deductible depending on how you use the funds.

Interest on loans used to purchase an investment property may be treated as investment interest expense or rolled into the property’s basis. Consult a tax professional for specifics.

Risks of Using a Cash-Out Refinance for Investing

While the strategy can be powerful, it comes with real risks.

⚠ 1. Higher Mortgage Payment on Your Primary Home

You’re increasing your loan balance and potentially your interest rate.

⚠ 2. Market or Tenancy Risk

If the rental sits vacant or cash flow is lower than expected, your primary home’s payment still must be made.

⚠ 3. Investment Property Loans Are Stricter

You may face:

• Higher interest rates

• Higher down payment requirements

• Higher reserve requirements

⚠ 4. Your Home Is Collateral

Missed payments put your residence—not your rental—at risk.

⚠ 5. Lower Long-Term Equity

A cash-out refinance reduces your home equity cushion, leaving less wiggle room if property values drop.

Cash-Out Refinance vs. HELOC for Investment Property Down Payments

Choose a Cash-Out Refinance When:

• You want fixed payments

• You need $40k–$150k+

• Your current mortgage rate is high anyway

Choose a HELOC When:

• You locked a low first-mortgage rate

• You only need limited funds

• You want repayment flexibility

Real-World Examples

Example 1: Buying Your First Rental

• Home value: $550,000

• Current loan: $330,000

• Cash-out loan @80% LTV: $440,000

• Cash available: ~$110,000

Down payment for a $400,000 rental (20%): $80,000

Remaining cash can fund closing costs and reserves.

Example 2: Purchasing a Duplex

• Home value: $750,000

• Current loan: $420,000

• Cash-out LTV: 80% → $600,000

• Cash available: ~$180,000

Duplex purchase price: $600,000

Down payment required (25%): $150,000

You have enough for the down payment + rehab budget.

Example 3: Building a Short-Term Rental Portfolio

A VA-eligible borrower with a primary home worth $500,000 refinances at 95% LTV.

• Max loan: $475,000

• Current balance: $300,000

• Cash-out: $175,000

Enough to buy multiple low-cost STRs or one larger destination rental.
