Buying a second home might sound like a luxury — but with the rise of short-term rentals (STRs), it’s become a strategic wealth-building move for everyday investors. The trick? Knowing how to finance it creatively and affordably. In this post, we’ll break down how to “house hack” your way into a vacation rental by using second-home loans, HELOCs, and owner-occupied financing strategies.

💡 What Is House Hacking?

At its core, house hacking means using your property to generate income and offset your living or ownership costs. In the STR world, this often looks like:

  • Renting your second home part-time to cover the mortgage

  • Living in the property part-time and renting the rest of the year

  • Using creative financing to make ownership possible with low out-of-pocket costs

It’s a hybrid approach — half lifestyle, half investment — and when done right, it makes owning a vacation rental far more accessible.

🏡 Option 1: Second-Home Loans (Fannie/Freddie)

One of the most common — and often overlooked — ways to finance a vacation rental is a conventional second-home loan.

Key Requirements:

  • Must be a one-unit property

  • You must live in it at least part of the year

  • Must be suitable for year-round occupancy

  • Can’t be a full-time rental property

📌 Pro Tip: Most lenders will still allow you to rent the property out when you’re not using it — even on Airbnb or VRBO — as long as it meets the “second home” intent.

Benefits:

  • As little as 10% down (with no PMI in some cases)

  • Competitive interest rates, often close to primary residence rates

  • Backed by Fannie Mae or Freddie Mac — easy to qualify if you meet debt-to-income (DTI) requirements

Best For: Buyers who want a hybrid lifestyle/investment property they can enjoy and rent.

💳 Option 2: HELOC or Home Equity Loan

If you already own a primary residence with equity, this could be your launchpad.

Home Equity Line of Credit (HELOC):
A revolving credit line you can draw from as needed — think of it like a giant credit card secured by your house.

Home Equity Loan:
A lump sum loan that gives you all the funds up front at a fixed interest rate.

Why It Works:

  • Use your existing home’s equity for the down payment

  • Keep your STR loan size smaller

  • Often quick to close and flexible

📌 Example: Let’s say your primary home is worth $500,000, and you owe $300,000. You could potentially access up to $100,000 in equity (depending on lender limits).

Best For: Homeowners with strong equity looking to avoid touching savings.

👣 Option 3: Owner-Occupied Strategy (Live In It First)

Here’s a curveball: Buy the home as a primary residence and live in it for at least 12 months. After that, convert it to a rental.

How It Works:

  • Use low-down-payment loans (FHA = 3.5%, Conventional = 3%, VA = 0% for veterans)

  • After 12 months, move out and start renting

  • Refinance into an investment loan if needed

This strategy opens doors for first-time investors or those with limited capital.

📌 Caution: Misrepresenting occupancy is mortgage fraud. Only use this strategy if you genuinely plan to live in the home for the first year.

Best For: Buyers who can work remotely or relocate and want to start small.

🔍 Compare the Options:

Strategy Down Payment Interest Rate Rental Allowed? Key Perk
Second Home Loan 10%+ Low Part-time OK High loan limits, low rates
HELOC / Home Equity Varies Medium Yes Tap into equity, fast access
Owner-Occupied Purchase 0–5% Very Low After 12 months Ideal for beginners, low cost

💼 Example Scenario: $500K Vacation Rental Purchase

  • Second Home Loan (10% down): $50K + closing costs, $450K loan

  • HELOC on Primary: Use $100K for down payment + setup costs, STR loan for $400K

  • Owner-Occupied: FHA 3.5% down = $17,500 + closing costs, live in for 12 months, then convert

💭 Final Thoughts

Financing a vacation rental doesn’t have to feel like a stretch — you just need to approach it like an investor, not a dreamer. Whether you’re tapping equity, living in your investment, or leveraging a second-home loan, the key is strategic intent.

And remember: The best financing strategy is the one that aligns with your lifestyle, risk tolerance, and long-term STR goals.
