Truss Financial Group (TFG) is among the first U.S. lenders to launch a true Hybrid STR Mortgage Program, built for today’s short-term-rental economy.

The line between home and business assets keeps blurring, especially for Airbnb hosts and vacation-rental investors. Traditional mortgages often ignore rental cash flow, while pure DSCR loans overlook personal income. The result? Many profitable short-term rental (STR) owners still fail to qualify under either system.

That’s changing in 2025.

Hybrid STR Mortgage Loans combine both worlds, the stability of a conventional mortgage and the flexibility of a DSCR (Debt Service Coverage Ratio) loan, allowing borrowers to qualify using both personal income and verified rental performance.

This new structure gives investors access to higher leverage, better rates, and smoother underwriting, all while recognizing the true economics of short-term rentals.

Truss Financial Group (TFG) is among the first U.S. lenders to offer this Hybrid STR Mortgage program in 2025, joining an emerging wave of innovators shaping the next generation of Airbnb and vacation-rental financing.

Why Hybrid STR Loans Are Emerging Now?

The short-term rental (STR) market has officially matured. Platforms like Airbnb, Vrbo, and Rabbu now provide years of verified rental data, from occupancy rates to seasonal revenue patterns, giving lenders reliable, third-party income projections for the first time.

Traditional mortgage lenders, however, still underwrite based on W-2 income and often limit how much of a property can be rented out. That leaves self-employed hosts and part-time investors underqualified, even when their listings generate consistent cash flow.

DSCR loans (Debt Service Coverage Ratio loans) solved part of the problem by focusing on property income rather than personal income. But they overlook borrower assets, blended use, or situations where an investor lives in part of the home like renting an ADU or separate unit on Airbnb.

The new Hybrid STR Mortgage model bridges that gap. It combines the cash-flow flexibility of DSCR underwriting with the stability of conventional income qualification, allowing investors to use both rental revenue and personal income to qualify.

This makes hybrid STR loans ideal for:

• “Live-rent” investors who occupy part of their property while renting the rest.
• Vacation-rental owners seeking higher leverage without full-commercial terms.
• Self-employed borrowers with verifiable assets but irregular income streams.

In short, the market data has finally caught up to the way modern real-estate investors actually operate and Hybrid STR Loans are the financing model built for that reality.

How a Hybrid STR Mortgage Works?

The Hybrid STR Mortgage combines two underwriting frameworks into one seamless loan, blending the predictability of a traditional mortgage with the performance-based flexibility of a DSCR (Debt Service Coverage Ratio) loan.

A) The Blended Dual-Structure Explained

Think of it as a “split” loan:

Traditional Portion:

This covers roughly 60% to 80% of the property’s value and is underwritten just like a standard mortgage based on personal income, credit score (typically 680+), and debt-to-income ratio (DTI) below 43%.

It provides long-term stability, fixed-rate options, and predictable payments.

DSCR Overlay Portion:

This layer finances the remaining 20% to 30% of the property’s value and is qualified using projected short-term rental (STR) cash flow.

Lenders calculate a DSCR ratio ≥ 1.0, meaning the property’s expected income covers its monthly debt obligations.

Together, these layers create a blended qualification model that evaluates both the borrower’s financial strength and the property’s actual earning potential, a perfect balance for today’s Airbnb and vacation-rental investors.

B) Income Verification

Think of it as a “split” loan:

Traditional Portion:

This covers roughly 60% to 80% of the property’s value and is underwritten just like a standard mortgage, based on personal income, credit score (typically 680+), and debt-to-income ratio (DTI) below 43%.

It provides long-term stability, fixed-rate options, and predictable payments.

DSCR Overlay Portion:

This layer finances the remaining 20% to 30% of the property’s value and is qualified using projected short-term rental (STR) cash flow.

Lenders calculate a DSCR ratio ≥ 1.0, meaning the property’s expected income covers its monthly debt obligations.

Together, these layers create a blended qualification model that evaluates both the borrower’s financial strength and the property’s actual earning potential, a perfect balance for today’s Airbnb and vacation-rental investors.

C) Key Product Highlights

• Qualify even with a lower DSCR if the overall borrower profile and asset base are strong.
• Down payments as low as 15%.
• Fixed or Hybrid ARM terms available (typically 5/6, 7/6, or 10/6 structures).
• Maximum combined loan-to-value (LTV) up to 85–90%, depending on occupancy and credit.
• Designed for investors expanding portfolios or converting vacation homes into income-producing properties.

Who Are Hybrid STR Loans Best For?

The Hybrid STR Mortgage isn’t a one-size-fits-all product, it’s a specialized solution built for borrowers who live in the overlap between homeownership and entrepreneurship. By blending personal income with short-term rental (STR) performance, it unlocks financing opportunities that traditional and DSCR loans can’t match.

Here’s who benefits most from this 2025 innovation in real-estate lending:

1. Airbnb Hosts Who Live and Rent on the Same Property

If you occupy part of your home, like a duplex, basement suite, or accessory dwelling unit (ADU), and rent out the rest on Airbnb or VRBO, a Hybrid STR Loan lets you finally count both income streams toward qualification.

Traditional lenders often disallow STR income for owner-occupied homes, while DSCR loans prohibit living on-site. This hybrid model bridges that gap, giving “live-rent” investors access to better rates and higher leverage.

2. Investors with Mixed-Use or ADU Properties

Whether you’re converting a garage into an ADU or managing a home that serves both as a residence and income property, hybrid STR loans recognize the dual-purpose nature of these assets.

They allow partial occupancy, variable income, and rental-based underwriting, all in one product, ideal for real-estate investors scaling into multi-unit or short-term rental portfolios.

3. Self-Employed Borrowers with Strong Assets but Variable Income

Entrepreneurs, consultants, and gig-economy professionals often have inconsistent income on paper but substantial assets or cash flow.

Hybrid STR Loans account for this by combining personal financials, business deposits, and rental performance to paint a more accurate borrower profile.

For many self-employed borrowers, this is the first time both personal effort and property performance are fully recognized in underwriting.

4. Seasonal Market Buyers in High-Demand States

If you’re buying or refinancing in Florida, Arizona, California, or mountain markets like Colorado and Utah, where rental income fluctuates seasonally, hybrid STR loans provide more breathing room.

Because they consider annualized income and occupancy-adjusted projections, investors in vacation or second-home markets can qualify more easily, even when off-season months bring lower revenue.

In short, Hybrid STR Loans are designed for a new generation of borrowers who want to live, rent, and invest, all within the same property. They’re perfect for homeowners who think like investors, and investors who still want the stability of a home.

Truss Financial Group’s Edge in Hybrid STR Lending

While other lenders are still repackaging DSCR loans for the short-term rental market, Truss Financial Group (TFG) has built a genuine dual-underwrite structure that evaluates both borrower income and property performance.

What Are the Benefits of a Hybrid STR Mortgage Loan?

The Hybrid STR Mortgage bridges the gap between residential and commercial lending, giving investors freedom without sacrificing structure.

Key Advantages:

• Higher Leverage: Combine personal and STR income for a larger qualifying loan amount and better loan-to-value ratios.
• Faster Approvals: Uses verified third-party STR data (Airbnb, Vrbo, Rabbu), no need for lengthy income documentation or tax returns.
• Flexible Property Use: Finance homes you live in part-time, rent seasonally, or manage as mixed-use.
• Tax Benefits: Retain residential terms while deducting short-term rental expenses and depreciation.
• Asset Protection: Title properties under an LLC, separating personal liability from business risk.

Example For Different Scenarios

Case 1 – Florida Coastal Hybrid

A real estate investor purchases a $700,000 duplex in the Florida Panhandle.

The borrower’s personal income qualifies for the main unit, while the Airbnb side generates $60,000 annually in verified STR income.

With a combined DSCR of 1.3, just 15% down, and a blended rate near 7%, the deal closes under TFG’s hybrid model, where a traditional lender would cap LTV or deny the file.

Case 2 – Scottsdale Vacation Home

A borrower lives in the property four months per year and rents it on Vrbo the rest of the time.

Using both income streams, the hybrid underwriting allows 80% LTV, compared to 70% or less with a DSCR-only loan, providing greater leverage with owner-occupancy flexibility.

Risks and Considerations

Even with its flexibility, the hybrid STR structure comes with nuances investors should understand:

• STR Volatility: Seasonal dips or local regulations can impact projected DSCR ratios.
• Complex Underwriting: Dual qualification (personal + rental) can lengthen prep time.
• Higher DSCR Layer Rates: Expect 1–2% higher rates on the DSCR portion compared to conventional loans.
• Regulatory Awareness: Check HOA and municipal STR rules before purchase to avoid post-closing restrictions.

TFG mitigates these risks with conservative income modeling, verified market data (Rabbu, AirDNA), and full compliance with state-level lending laws.

How to Apply for a Hybrid STR Mortgage?

Step 1 – Initial Consultation

Schedule a short call with TFG’s lending team. You’ll review your property details, projected STR income (Airbnb/Vrbo data), and personal financials to determine eligibility.

Step 2 – Hybrid Pre-Qualification

Both income streams are modeled together: borrower + property, to establish your qualifying loan amount and target LTV.

Step 3 – Dual Underwriting Process

Your application runs through two parallel tracks: conventional income underwriting and DSCR overlay. Combined results are reviewed for final approval.

Step 4 – Final Approval & Closing

Average closing timeline: 30–45 days. Borrowers may take title in an LLC, access hybrid-rate options, and begin STR operations immediately post-funding.

Frequently Asked Questions FAQ

What is a Hybrid STR Loan?

A Hybrid STR (Short-Term Rental) Loan is a dual-structure mortgage that combines elements of a traditional loan and a DSCR (Debt Service Coverage Ratio) loan.

It allows borrowers to qualify using both personal income and projected rental income from platforms such as Airbnb, Vrbo, or Rabbu. This blended approach offers more flexibility for investors who live in or partially rent out their properties.

What is an STR Loan?

An STR loan, short for Short-Term Rental loan, is a type of non-QM investment loan designed for properties operated as short-term rentals or vacation homes.

Instead of using tax returns or W-2 income, lenders qualify borrowers based on the property’s rental income performance, usually verified through AirDNA, Rabbu, or management statements. These loans are popular with Airbnb hosts and real-estate investors expanding their rental portfolios.

Are DSCR loans hard to get?

DSCR loans are generally easier to qualify for than conventional mortgages because they rely on property cash flow, not personal income.

However, lenders may tighten standards if the DSCR ratio falls below 1.0 (where expenses exceed income). In those cases, a Hybrid STR Loan can help borrowers qualify by adding personal or business income to the equation, improving approval odds and loan terms.

How does a hybrid loan work?

A hybrid loan uses two underwriting layers:

1. Traditional underwriting: based on the borrower’s credit, assets, and income.
2. DSCR underwriting: based on the property’s projected rental cash flow.

Both results are combined to produce one blended qualification model. This structure supports higher loan-to-value ratios, flexible property use (live + rent), and faster funding timelines.

Which is the best lender for Hybrid STR loan?

Truss Financial Group (TFG) is among the first U.S. lenders to launch a true Hybrid STR Mortgage Program in 2025.

Unlike standard DSCR lenders that rely solely on property income, TFG’s model evaluates both the borrower’s verified income and short-term rental performance, allowing for up to 90% LTV, 15% down payments, and eligibility for LLC-titled properties.

This makes TFG one of the most flexible and forward-looking lenders for Airbnb and vacation-rental financing.
