Fannie Mae Small Balance Loan (under $6M): What Brokers Need to Know

A Fannie Mae Small Balance Loan is an agency-backed multifamily mortgage typically sized from $1 million to $6 million, with non-recourse execution, up to 80% LTV, 30-year amortization, and a 1.25x minimum DSCR. The program offers brokers and their clients access to agency-quality financing on smaller apartment properties that would otherwise rely on community banks or local portfolio lenders. For commercial mortgage brokers who place multifamily deals, the Fannie Mae Small Balance Loan is one of the two dominant capital sources (along with the Freddie Mac SBL) for stabilized small-balance multifamily across the country.

This guide covers how the program works, what qualifies, typical terms, how underwriting compares to standard Fannie Mae DUS, broker packaging tips, and when alternative financing makes sense.

Program Overview: Fannie Mae Small Balance Loan

The Fannie Mae Small Balance Loan program (often shortened to Fannie Mae Small Loan or Multifamily Small Loan) is delegated to a network of Fannie Mae-approved Small Loan lenders. These lenders underwrite, close, and service loans on Fannie Mae's behalf using Fannie Mae's standardized program guidelines. Because the program is delegated and standardized, execution is faster than custom DUS underwriting and pricing is more transparent.

The program exists to serve a structural gap in multifamily lending. Standard Fannie Mae DUS underwriting carries fixed costs (legal, third-party reports, lender review) that make smaller deals economically inefficient for both the lender and borrower. At the same time, community banks and local portfolio lenders typically offer shorter terms (5 to 10 years), recourse, and floating rates rather than the long-term fixed-rate, non-recourse execution that institutional multifamily owners want. The Small Balance Loan fills that middle ground.

Eligible Properties for Fannie Mae Small Balance Loans

The Fannie Mae Small Balance Loan finances conventional multifamily properties that meet the following general criteria:

• Property type: Apartment buildings with 5 or more units. Includes garden-style, mid-rise, and high-rise multifamily. Townhome rental properties may qualify in some cases.
• Occupancy: Stabilized, generally 90% occupied for the trailing 90 days. Some markets and property types require higher sustained occupancy.
• Geographic eligibility: All 50 states, with population and market tier thresholds. Top 50 MSAs and standard markets carry the broadest program eligibility. Smaller markets (population 25,000 to 100,000) may require additional Fannie Mae review and can carry slightly higher DSCR floors. Very small or rural markets may not qualify.
• Property condition: Generally good to excellent property condition with limited deferred maintenance. Properties with substantial repairs needed typically require a separate repair escrow or a different loan product.
• Affordability: Conventional market-rate properties qualify, as do affordable properties that meet Fannie Mae's Multifamily Affordable Housing (MAH) Small Loan criteria. Properties with Section 8, LIHTC, or other affordability layers can be financed with specialized affordable underwriting.

Ineligible property types include hotel and hospitality, senior housing (which goes through Fannie Mae's dedicated seniors housing program; see our Fannie Mae loan for senior housing guide), student housing (separate program), manufactured housing communities (separate program), commercial properties, and properties with more than minor commercial income (typically under 20% of effective gross income).

Typical Fannie Mae Small Balance Loan Terms

The Fannie Mae Small Balance Loan is sized to the tighter of the LTV constraint and the DSCR constraint. In higher-rate environments, DSCR often becomes the binding constraint, which means borrowers may achieve less than 80% LTV even on strong properties. Brokers should run both constraints during pre-sizing.

How Fannie Mae Small Balance Loan Underwriting Works

Underwriting on the Fannie Mae Small Balance Loan follows a standardized program but still requires the documentation, third-party reports, and analysis that any agency loan requires. Key underwriting components:

Net operating income. Underwritten NOI is the foundation of the loan size. Lenders use trailing 12 months of operating statements as the starting point, with adjustments for verifiable rent increases, expense normalizations, and forward-looking adjustments. Vacancy and credit loss are typically underwritten at the higher of actual and a market-based vacancy assumption (often 5% to 7%). Property tax is generally underwritten at the higher of trailing actual and post-acquisition reassessment estimate. See our NOI glossary entry for the full waterfall.

DSCR sizing. The loan is sized so that underwritten NOI divided by annual debt service meets the program minimum (1.25x standard). Use the DSCR calculator to model deals before submission.

LTV sizing. The appraised value (from a Fannie Mae-approved appraiser) sets the LTV ceiling. Up to 80% LTV is available on most deals, with some flexibility based on borrower experience and market quality. Use the LTV calculator to size against value.

Debt yield. Some Fannie Mae Small Loan lenders apply a minimum debt yield floor (often 7% to 8%) as a third sizing constraint, particularly on higher-leverage requests. Use the debt yield calculator to check this metric.

Borrower and sponsor evaluation. Borrowers are typically required to be U.S. citizens or domestic entities with U.S. ownership. Sponsor net worth requirements generally require liquid net worth equal to at least 100% of the loan amount and post-closing liquidity equal to at least 9 months of debt service. Credit score minimums vary but generally cluster around 680 to 700.

Property condition. A property condition assessment (PCA) identifies immediate and long-term capital needs. Significant deferred maintenance can require a repair escrow or replacement reserves above the standard underwritten amount. Environmental Phase I screening is standard.

Market analysis. Lenders evaluate submarket fundamentals, rent comparables, supply pipeline, and demographic trends. Small markets and slow-growth markets may require additional Fannie Mae review and can carry tighter underwriting.

Fixed Rate vs Hybrid ARM Options

Fannie Mae Small Balance Loan borrowers choose between fixed-rate and hybrid ARM structures based on hold strategy and rate outlook.

Fixed-rate options (5, 7, 10, 12 years) offer payment certainty for the full term, with the entire principal and interest payment locked at closing. The 7-year and 10-year fixed are the most common selections, balancing rate cost with hold flexibility. Longer fixed terms typically price slightly higher than shorter terms. Prepayment is structured as either yield maintenance or step-down (declining) prepayment.

Hybrid ARM options (5/6, 7/6, 10/6) offer a fixed initial period followed by 6-month adjustments tied to a benchmark index plus a margin. The fixed period typically prices below the comparable fixed-rate option, which can save interest cost for borrowers planning to refinance or sell before the adjustment period. Brokers should model the rate cap, margin, and index reset to show borrowers their downside scenario after the fixed period expires.

For most stabilized buy-and-hold deals, the 10-year fixed has historically been the default selection. Hybrid ARMs are more common for value-add deals where the sponsor expects to refinance after stabilization, or for sponsors with strong views that rates will decline before the adjustment period.

Broker Packaging Tips for Fannie Mae Small Balance Loans

Brokers who consistently win Fannie Mae Small Balance Loan business follow a few packaging discipline practices:

1. Pre-size both DSCR and LTV. Don't submit a deal sized only to 80% LTV without also confirming the deal meets the 1.25x DSCR minimum at current rates. Use both the DSCR calculator and LTV calculator at the rate the lender is quoting. If DSCR is the binding constraint, present the loan at the DSCR-supported amount rather than overpromising the borrower 80% LTV.
2. Lead with the trailing 12 months. The T-12 operating statement is the foundation of underwriting. Provide a clean T-12, monthly P&L for each of the last 12 months, and a current rent roll. Identify any one-time items (insurance refunds, one-time repairs, owner perks) and explain them upfront.
3. Address property tax post-acquisition. On acquisitions, model the post-reassessment property tax bill. Lenders will run their own forward tax estimate; presenting yours first signals you understand the underwriting.
4. Quote both Fannie Mae and Freddie Mac. The Fannie Mae Small Balance Loan competes with the Freddie Mac Small Balance Loan (SBL) for the same deals. Pricing fluctuates between the agencies, and the right answer changes from week to week. Always quote both. See our Freddie Mac Conventional and Optigo guide.
5. Document sponsor liquidity early. Lenders verify sponsor liquidity (typically 9 months of debt service post-closing) before issuing a final commitment. Collecting bank statements, brokerage statements, and a personal financial statement at application reduces back-and-forth later in the process.
6. Identify ineligible income. If the property has commercial income, laundry income, vending, or other non-residential income, identify it upfront. Income above the 20% commercial threshold can disqualify the property from the Small Loan program.
7. Be honest about deferred maintenance. The property condition assessment will find what's there. Disclose known issues, include any contractor bids you have, and frame them as part of the post-closing capital plan. Surprises kill deals.

When the Fannie Mae Small Balance Loan Isn't the Right Fit

The Fannie Mae Small Balance Loan is a strong default for stabilized small-balance multifamily, but several situations call for alternative financing:

• Properties below $1 million. Smaller deals often go to community banks, credit unions, or local portfolio lenders. The fixed costs of agency underwriting (third-party reports, lender legal) make sub-$1M deals economically tight on the agency programs.
• Properties above $6 million. Larger deals move into standard Fannie Mae DUS underwriting, which offers more flexibility on terms, leverage, and interest-only structure. See our Fannie Mae multifamily guide.
• Properties below 90% occupancy. Lease-up properties need bridge financing to carry them through stabilization before refinancing into agency debt. See our bridge-to-perm financing for multifamily guide.
• New construction. Agency Small Loan products only finance stabilized properties. New construction requires a construction loan from a bank or debt fund, with HUD 221(d)(4), Fannie Mae DUS, or Freddie Mac as takeout options after stabilization. See construction loan deals getting closed and the HUD 221(d)(4) glossary entry.
• Properties with substantial deferred maintenance. Properties needing significant capital improvements may need bridge financing or HUD 223(f) with a repair escrow. See the HUD 223(f) glossary entry.
• Senior housing, student housing, manufactured housing. Each of these property types runs through dedicated Fannie Mae programs with separate underwriting and terms.
• Recourse-tolerant borrowers with shorter holds. Borrowers planning to sell or refinance within 3 to 5 years may find better economics with a recourse community bank loan that avoids agency prepayment penalties.

Fannie Mae Small Balance Loan vs Other Small Multifamily Financing Options

Pricing and Rate Indications

Fannie Mae Small Balance Loan rates price as a spread over the corresponding Treasury benchmark (5-year Treasury for 5-year loans, 7-year Treasury for 7-year loans, 10-year Treasury for 10-year loans). The spread varies based on loan size, leverage, term, borrower strength, and overall market conditions. Spreads typically tighten on cleaner deals (lower leverage, higher DSCR, experienced sponsor, top-50 MSA) and widen on tougher deals.

Rates change daily and are subject to lender pricing memos. The Fannie Mae Small Loan and Freddie Mac SBL programs rotate which one prices best from week to week, which is why brokers should always quote both. Lock periods vary by lender, with most offering 30 to 90-day rate locks. Some lenders offer early rate lock options (60 to 180 days before closing) for an additional fee. The commercial mortgage calculator can model payment scenarios at the rate the lender is quoting.

Borrower Costs to Expect

Borrowers should budget for the following typical costs on a Fannie Mae Small Balance Loan transaction:

• Application fee: Generally $5,000 to $15,000, applied toward third-party report costs.
• Origination fee: Typically 1% of loan amount.
• Third-party reports: Appraisal ($4,000 to $8,000), property condition assessment ($3,000 to $6,000), Phase I environmental ($2,500 to $5,000).
• Lender legal: $5,000 to $15,000 depending on deal complexity.
• Title and survey: Varies by state and property size.
• Lender counsel and rate lock deposits: Vary by lender.
• Replacement reserves: Typically $250 to $300 per unit per year, escrowed monthly.
• Tax and insurance escrows: Standard monthly impound for property taxes and insurance.

Total third-party and closing costs typically run 1.5% to 3% of the loan amount on a small-balance deal, with smaller deals trending toward the higher end as fixed costs become a larger percentage.
