A conventional mortgage can finance more than a primary residence. It may also be used to purchase or refinance an eligible one-to-four-unit investment property.

However, once you will not occupy the property, the lender evaluates the transaction differently. Down payment, pricing, reserves, rental-income documentation, and property requirements can all change.

Understanding those differences before making an offer can help you prepare for the true cost of financing.

What Is a Conventional Investment Loan?

A conventional investment loan is a mortgage used to finance a non-owner-occupied residential property. Unlike an FHA, VA, or USDA loan, it is not insured or guaranteed by a government agency.

Eligible properties may include:

• Single-family rental homes
• Condominiums
• Townhomes
• Duplexes
• Triplexes
• Four-unit residential properties

Property and condominium-project eligibility requirements still apply.

Conventional investment financing is also different from a DSCR loan. With a conventional loan, the lender generally reviews the borrower's personal income, employment, assets, credit, and debts. A DSCR loan focuses more heavily on the property's ability to support its own mortgage obligation.

The Down Payment Is Usually Higher

Primary-residence programs may allow lower down payments because the borrower will live in the home.

Investment properties generally require a larger contribution. The exact requirement depends on:

• Number of units
• Credit profile
• Loan amount
• Property type
• Automated underwriting findings
• Purchase or refinance transaction
• Conventional program
• Lender guidelines

A one-unit investment property may have different requirements from a duplex, triplex, or four-unit property.

Do not assume the minimum down payment will produce the best loan structure. A larger down payment may improve pricing, reduce the monthly payment, strengthen cash flow, and help the property qualify.

Interest Rates and Fees May Be Higher

Investment properties are considered a greater lending risk than primary residences. As a result, conventional investment loans may include pricing adjustments that increase the rate or upfront cost.

Pricing can be affected by:

• Credit score
• Loan-to-value ratio
• Number of units
• Property type
• Loan purpose
• Mortgage term
• Adjustable versus fixed rate
• Condominium characteristics

The lowest down-payment option is not always the lowest-cost option. Investors should compare the cash required at closing with the payment, rate, and long-term return.

Cash Reserves Become More Important

The lender may require the borrower to retain funds after closing.

Reserves are generally measured by the number of months of required housing payments that could be covered by the borrower's eligible assets.

For example, if the complete monthly property payment is $2,500 and six months of reserves are required:

$2,500 × 6 = $15,000 in reserves

That money is separate from the down payment and closing costs.

Under Fannie Mae's automated underwriting guidelines, an investment-property transaction generally requires six months of reserves. Additional reserves can apply when a borrower owns other financed properties.

Actual requirements depend on the complete loan scenario and underwriting findings.

Rental Income Is Not Always Counted Dollar for Dollar

Projected rent may help a borrower qualify, but the lender will not necessarily accept 100% of the expected amount.

When lease or market-rent documentation is used under Fannie Mae guidelines, the lender generally calculates qualifying rental income using 75% of gross monthly rent. The remaining 25% accounts for potential vacancy and ongoing maintenance.

For example:

• Estimated monthly rent: $2,000
• Qualifying amount: $2,000 × 75% = $1,500

The accepted rent may need to be supported by:

• A current lease
• The property appraisal
• Form 1007 for an eligible one-unit investment property
• Form 1025 for an eligible two-to-four-unit property
• Tax returns and Schedule E for existing rental properties
• Evidence of rent payments or deposits in certain situations

A borrower's rental-property experience and tax-return history may also affect how the income is treated.

Personal Qualification Still Matters

The fact that the property will produce rent does not eliminate traditional underwriting.

The lender may still evaluate:

• Employment and income
• Credit history
• Debt-to-income ratio
• Available assets
• Existing mortgages
• Other financed properties
• Housing-payment history
• Tax returns
• Rental-income history

If the qualifying rental income does not completely offset the property's housing expense, the difference may increase the borrower's monthly obligations.

This is one reason an investor can find a property with positive projected cash flow but still have difficulty qualifying for conventional financing.

The Property Must Meet Conventional Standards

A conventional investment property generally must be safe, structurally sound, and suitable for year-round occupancy.

Properties with major condition issues may create financing challenges, including:

• Missing kitchens or bathrooms
• Active roof leaks
• Unsafe electrical systems
• Significant structural damage
• Incomplete construction
• No functioning utilities
• Serious health or safety concerns

An investor planning substantial renovations may need a renovation loan, bridge loan, or other financing before the property can qualify for permanent conventional financing.

Occupancy Must Be Reported Accurately

An investment property cannot be labeled as a primary residence simply to obtain a smaller down payment or better loan terms.

A primary residence is a property the borrower genuinely intends to occupy as a home. An investment property is purchased primarily to generate income, appreciation, or both without the borrower living there.

Misrepresenting occupancy can constitute mortgage fraud and may lead to loan denial, acceleration of the loan, financial penalties, or other consequences.

An owner-occupied duplex, triplex, or four-unit property may offer a legitimate alternative. The borrower can live in one unit and rent the others, subject to the applicable program's occupancy and underwriting requirements.

Primary Residence vs. Investment Property

The Bottom Line

Conventional investment financing can be a strong option for borrowers with documentable income, solid credit, sufficient funds, and a qualifying residential property.

Before submitting an offer, determine:

• Required down payment
• Estimated rate and payment
• Closing costs
• Required reserves
• Acceptable rental income
• Effect on your debt-to-income ratio
• Property-condition requirements
• Projected cash flow
