Carrier appetite summary
Neptune Flood is a U.S.-only flood MGA writing private primary and excess flood nationwide in all 50 states. Current published appetite includes residential dwellings (single-family, 2-4 family, condo units, apartment/renter units), commercial business risks under its Main Street Mercantile form, apartment buildings/co-ops, hotels/motels/inns, and RCBAP condo association business. Preferred operational fit is straightforward flood business that can be quoted digitally by address with fast turnaround; Neptune states quotes/binds can be completed in about two minutes and generally does not require elevation certificates, photos, replacement cost estimates, or valuation documents for the cited residential/commercial materials. Geographic availability is all 50 states, U.S. only, but Neptune specifically says it will not write homes in Fire Island NY, Padre Island TX, Block Island RI, Chesterfield Flats MO, Topsail Beach NC, or Monroe County (Key West) FL. Published hard restrictions/declines include properties with more than one flood loss, any single flood loss over $25,000, manufactured/mobile homes, and buildings located partially or entirely in, on, or over water; Neptune also notes its Triton risk engine may decline additional locations based on flood likelihood, location characteristics, elevation, and related risk factors even if they do not hit a listed rule. Excess flood is available across product types only over an existing NFIP primary policy, not over another private or Neptune primary policy, and Neptune assumes underlying NFIP limits at the maximum available amounts. Published limits indicate up to $7M Coverage A / $500k Coverage B for residential in non-V zones, up to $4M / $500k in V zones; commercial up to $10M / $500k in non-V zones and $4M / $500k in V zones; and RCBAP up to $15M building / $500k contents. Commercial flyer guidance adds non-residential square-footage parameters of no minimum and 100,000 sq. ft. maximum in A/X zones, and no minimum with 25,000 sq. ft. maximum in V zones. Submission/broker notes: Neptune directs agents to its agent hub, states one building per policy unless attached, offers contents-only options for tenant occupancies, and suggests adding the owner as additional insured when protecting the building for leased space. Waiting-period guidance shown in Neptune materials: no wait for real-estate closings with valid closing statement; otherwise 10 days on older residential guide material and 30 days on the cited commercial comparison flyer, so brokers should confirm current form-specific waiting period at quote/bind.
