How Flat 35S reduces the rate for qualifying housing performance, and how long the discount lasts.
Flat 35S is a rate-reduction framework for homes meeting higher standards in energy efficiency, seismic performance, durability, or accessibility — but the reduction applies for specified initial years, not the whole term.
Flat 35S is a rate-reduction framework layered on top of Flat 35 for homes that meet higher standards in categories such as energy efficiency, seismic performance, durability and variability, or accessibility. A qualifying home earns a reduction to the Flat 35 rate for a specified number of initial years — the exact reduction and the number of discounted years depend on the plan tier and the property’s certified performance. After the discounted period ends, the standard Flat 35 rate resumes for the remaining term.
Because the reduction is temporary, model your payment both during and after the discounted years — a home that looks affordable on the reduced rate must still be affordable at the full rate. Confirm which performance category the property qualifies under, obtain the certification, verify the reduction size and the number of discounted years with the provider, and remember that these frameworks are updated periodically, so check the current terms rather than an older figure. Flat 35S can meaningfully lower early costs for an efficient or seismically strong home, but it is not a permanent rate cut.
Key points to carry away: Flat 35S reduces the Flat 35 rate for homes meeting qualifying performance standards; The reduction applies for a set number of initial years, then the standard rate resumes; Performance categories include energy efficiency, seismic, durability, and accessibility; Confirm the qualifying category, the reduction size, and the discount duration.
