5% Down Primary Home Purchase: How We Overcame Rental Income Challenges to Close On Time

Buying a primary residence with a low down payment can already feel overwhelming in today’s competitive housing market. When complex income scenarios are added into the mix, securing financing can become even more challenging.

At First Liberty Funding, we recently helped a client successfully close on a primary home purchase with just 5% down despite significant underwriting obstacles tied to rental income qualification and lender overlays.

This transaction is a great example of how experienced mortgage structuring, persistence, and problem-solving can make the difference between a denied loan and a successful closing.

The Scenario: Purchasing a Primary Residence With 5% Down

Our client was purchasing a new primary residence while converting their existing property into a rental property. The plan was to use projected rental income from the departing residence to help qualify for the new home loan.

On the surface, the borrower appeared highly qualified:

• Strong credit profile
• Stable employment and income
• Solid financial history
• Significant equity in the departing property

However, the transaction became more complicated during underwriting due to how the rental income was being evaluated.

The Challenge: Rental Income and Lender Overlays

One of the biggest challenges in mortgage lending today is navigating lender overlays.

Lender overlays are additional requirements imposed by individual lenders beyond standard agency guidelines. Even when a loan technically meets baseline mortgage guidelines, overlays can create stricter qualification requirements.

In this case, the borrower did not have a traditional documented primary housing expense history, such as:

• A current primary mortgage payment
• Verifiable rent payments
• Established housing payment documentation

Because of this, the lender applied additional scrutiny to the file.

Although the projected rental income from the departing property was fully documented, underwriting concerns arose around how much of that income could actually be used for qualification purposes.

This situation is increasingly common for borrowers transitioning properties, especially in competitive housing markets like San Diego where homeowners may convert previous residences into investment properties while upgrading into a new home.

Why Underwriting Can Be Complex in These Situations

When borrowers use rental income to qualify for a mortgage, underwriters must determine whether the income is stable, documented, and likely to continue.

In many cases, lenders may require:

• Signed lease agreements
• Proof of security deposits
• Evidence of prior landlord experience
• Reserve requirements
• Documentation showing the borrower can manage multiple housing obligations

Additionally, some lenders reduce the usable rental income amount to account for vacancies, maintenance costs, or market risk.

The absence of a documented housing history can sometimes increase perceived risk, even for otherwise strong borrowers.

This is why having a mortgage team that understands guideline interpretation and lender-specific overlays is critical.

The Solution: Strategic Loan Resubmissions

Rather than accepting the initial underwriting resistance, our team focused on restructuring and strengthening the loan file.

We resubmitted the loan multiple times with strategic improvements designed to directly address underwriting concerns.

Key adjustments included:

• Repositioning how the rental income was presented
• Strengthening supporting documentation
• Providing additional clarification regarding the departing residence
• Working directly with underwriting teams to explain the borrower’s financial profile
• Leveraging guideline expertise to navigate lender overlay requirements

Throughout the process, communication became extremely important. We maintained close coordination with underwriting, escrow, and all parties involved to keep the transaction moving forward.

Adding a Co-Borrower to Strengthen the File

As the file progressed through underwriting, we identified another strategic option that could improve the overall approval strength.

We added a co-borrower to the transaction.

This adjustment strengthened the loan profile and helped satisfy lender requirements without changing the borrower’s overall homeownership goals.

Sometimes small structural changes can significantly improve loan eligibility, especially when navigating stricter underwriting environments.

At First Liberty Funding, we focus on finding practical solutions rather than immediately assuming a transaction cannot work.

The Result: Clear to Close On Time

Despite the underwriting challenges and multiple resubmissions, we successfully secured full loan approval and closed within the original contract timeline.

The borrower achieved their goal of purchasing a primary residence with only 5% down exactly as planned.

In fast-moving real estate markets, closing on time matters. Delays can create additional stress, jeopardize contracts, or even cause buyers to lose homes altogether.

This transaction demonstrates how persistence and strategic mortgage planning can help overcome complex financing obstacles.

Why the Right Mortgage Team Matters

Not all mortgage lenders approach complex files the same way.

Two lenders can review the exact same borrower profile and arrive at completely different outcomes depending on:

• Overlay requirements
• Underwriting interpretation
• Experience with complex income structures
• Communication between loan teams and underwriters

Working with an experienced mortgage team can provide major advantages, especially for borrowers with non-traditional scenarios.

An experienced mortgage team can help with:

• Creative loan structuring
• Rental income qualification strategies
• Low down payment loan options
• Navigating underwriting conditions
• Coordinating with escrow and real estate agents
• Identifying solutions before problems become deal breakers

Final Thoughts: Complex Loans Can Still Close Successfully

Every borrower’s financial situation is different.

Complex income structures, rental property transitions, and underwriting overlays do not automatically mean a loan cannot be approved. Often, the difference comes down to strategy, documentation, and persistence.

This recent closing is a reminder that problem-solving matters in mortgage lending.

If you are planning to purchase a primary residence with a low down payment, use rental income to qualify, or navigate a more complicated financial scenario, working with the right mortgage team can make a significant difference.
