Fannie Mae Small Balance Multifamily Loans: The Complete Guide

If you own a small apartment building — typically 5 to 50 units — and you’re looking to refinance, Fannie Mae’s Small Balance Loan (SBL) program is one of the most competitive options on the market. Better rates than most banks, longer terms, non-recourse, and a faster process than HUD. Here’s what you need to know.

What Is a Fannie Mae Small Balance Loan?

Fannie Mae’s Small Balance Loan program (sometimes called SBL or Fannie SBL) is a standardized multifamily loan product for smaller apartment properties. It’s designed to fill the gap between small community bank loans and larger agency executions that typically start at $5M+.

Key features:

• Loan size: $750,000 to $7.5 million
• Terms: 5, 7, 10, 12, or 15-year fixed or hybrid ARM options
• Amortization: Up to 30 years
• LTV: Up to 80% for acquisition; 75% for cash-out refinance
• DSCR: Minimum 1.25x (can go to 1.20x with rate buydown in some cases)
• Non-recourse with standard carve-outs
• Assumable (with Fannie Mae approval)

Rates are typically priced off the 10-year Treasury plus a spread — in most market environments, significantly below conventional bank financing.

Who Is This Program For?

Fannie SBL is built for stabilized, income-producing multifamily properties. You’re a good fit if:

• You own a 5–50 unit apartment building that’s been operating for at least 1 year
• The property is at least 90% occupied (with 90-day seasoning)
• You’re looking for a long-term, low-rate refinance — not a quick flip or value-add play
• You want non-recourse debt
• You’re in a market Fannie deems eligible (most major metro areas and secondary markets)

It’s not a fit if your property is in rough shape, occupancy is below 90%, you need to close in under 30 days, or the loan size is under $750K.

How Fannie SBL Compares to Other Multifamily Options

| Program | Loan Size | Rate | Timeline | Recourse | |———|———–|——|———-|———| | Fannie SBL | $750K–$7.5M | Best | 30–45 days | Non-recourse | | HUD 223(f) | $1M+ | Slightly better | 4–9 months | Non-recourse | | Freddie SBL | $750K–$7.5M | Comparable | 30–45 days | Non-recourse | | Bank / Portfolio | Any | Higher | 30–60 days | Usually recourse | | Debt Fund Bridge | Any | Much higher | 2–3 weeks | Varies |

Fannie and Freddie SBL programs are the most common execution for sub-$7.5M apartment refinances where the property is stabilized. HUD is better for long-term holds (35-year term vs. 15-year max for Fannie), but the timeline and closing costs are significantly higher.

The Process: What to Expect

Fannie SBL is processed through approved Delegated Underwriting and Servicing (DUS) lenders — not directly through Fannie Mae. Your broker or lender will submit to a DUS lender who has authority to approve and close the loan.

Typical timeline:

1. Application and quote: 3–5 days
2. Third-party reports ordered: Appraisal, Phase I environmental, property condition assessment — allow 2–3 weeks
3. Underwriting and commitment: 2–3 weeks after reports received
4. Closing: 1–2 weeks after commitment

Total: 30–50 days in most cases, sometimes faster.

Required third-party reports add cost — budget $5,000–$10,000 for appraisal, environmental, and property inspection. These are standard across all agency executions.

What Underwriters Focus On

Occupancy history. Fannie wants to see 90%+ occupancy for at least 90 days. Don’t apply if you’re still leasing up.

Actual income, not pro forma. Like HUD, Fannie underwrites based on trailing 12-month actual income. Projected rent bumps don’t count until leases are signed.

Property condition. The property condition assessment will flag deferred maintenance. Significant issues require repair escrows. Properties with major capital needs may not qualify until repairs are completed.

Borrower net worth and liquidity. Standard Fannie requirement: net worth equal to the loan amount, and post-closing liquidity of at least 9 months of debt service. These are the most common sticking points for smaller borrowers.

Market. Fannie will approve or require a higher rate in markets they consider higher-risk. Rural properties or properties in markets with weak rent trends may face challenges.

Cash-Out Refinance with Fannie SBL

Yes, you can pull cash out — up to 75% LTV on a refinance. If you have significant equity built up, this is one of the cleanest ways to access it long-term. The cash-out is unrestricted — you can use it for another acquisition, capital improvements, or any business purpose.

One important note: cash-out triggers recapture provisions if the property was purchased with certain affordable housing benefits. This is uncommon but worth flagging with your broker.

Frequently Asked Questions

Does the property need to be in my name or can it be in an LLC? LLC, LP, or other entity structures are fine and actually preferred. Fannie SBL is non-recourse, which pairs well with entity ownership.

What markets does Fannie SBL cover? Fannie SBL is available nationally, but markets are tiered. Top-tier markets (major metros) get the best terms. Smaller and rural markets may face LTV restrictions or be ineligible entirely.

Can I use Fannie SBL for a mixed-use property? Only if residential use is the primary use (typically 80%+ of income). Mixed-use with significant retail may need to go conventional or to a portfolio lender.

What if I’m slightly under 90% occupancy? Talk to your broker — some flexibility exists if you’re at 87–89% and can document a clear path to 90%. The lender may be able to structure with a holdback or escrow. Below 85%, you’ll likely need to wait or bridge.

How RefiLoop Helps

Accessing Fannie Mae SBL requires working through an approved DUS lender — you can’t go direct. A good broker knows which DUS lenders are most competitive for your market, property type, and loan size, and can get you multiple quotes rather than just one.

RefiLoop works with multifamily borrowers across Texas, Florida, Georgia, North Carolina, Ohio, and beyond — from small 5-unit buildings to 50-unit complexes. If your loan is maturing or you want to lock in agency rates on your apartment building, let’s see what you qualify for.
