What is Freddie Mac Optigo and how does it compare to Fannie DUS?
Last reviewed: June 13, 2026
Short answer
Optigo is Freddie Mac's branded multifamily platform with three channels: Conventional (≈$1M-$100M+, K-Series), Small Balance Loan (SBL, $1M-$7.5M), and Targeted Affordable Housing. Conventional Optigo prices within 5-15 bps of equivalent Fannie DUS; the main structural difference is defeasance availability on K-Series.
The three Optigo channels
- Conventional Optigo — $1M-$100M+ senior debt, K-Series securitization; the direct analog to Fannie DUS
- Small Balance Loan (SBL) — $1M-$7.5M for 5+ unit properties; streamlined docs for smaller sponsors
- Targeted Affordable Housing (TAH) — LIHTC / Section 8 deals with Mission Driven pricing and longer IO
Standard Conventional Optigo parameters
- Term: 5/7/10/12/15/20 years; 30-year amortization; up to 10-year full-term IO at ≤65% LTV
- LTV: up to 80% market-rate / 75% affordable / 75% senior / 65% student
- DSCR: 1.25x standard, 1.30x full-term IO, lower on affordable
- Prepayment: yield maintenance during lockout; defeasance available on K-Series; open at par the last 3-6 months
Key differences vs Fannie DUS
- Defeasance via CMBS bond purchase is available on Conventional Optigo K-Series; Fannie DUS uses yield maintenance only
- Tier classifications overlap but aren't identical — one agency can beat the other on the same deal in some secondary markets
- SBL ceiling is $7.5M vs Fannie's $9M Small Loan ceiling
- Freddie's TAH program is generally more developed than Fannie's Mission Driven equivalent
- Optigo Green Up rebates 15-30 bps and/or a forgivable deferred-loan portion for qualifying energy retrofits
