Average Rent in New Castle, Delaware

By the AverageRentCost Editorial Team · Last updated: October 2026

The FY2027 Fair Market Rent for a 2-bedroom home in New Castle is $1,860 a month, on HUD's gross-rent scale that includes utilities. New Castle sits in the Philadelphia-Camden-Wilmington, PA-NJ-DE-MD MSA, and its figures place it #1 among the 3 county rent listings published for Delaware — $231 (14%) above the Delaware county median. With a 2024 population of about 577,961, it is one of the rental markets we track in depth: below is the full bedroom-by-bedroom table, the income each size implies under the 30% rule, and how the county compares with its state and the country.

FY2027 Fair Market Rents in New Castle

The gaps between sizes tell you how this market prices space. In New Castle, stepping up from an efficiency to a one-bedroom adds $120 a month; stepping up from a one-bedroom to a two-bedroom adds $302 a month; and stepping up from a two-bedroom to a three-bedroom adds $356 a month. Families feel those steps directly, because voucher size standards and the 30% math both key off the bedroom count: a household approved for a 2-bedroom voucher that rents a 3-bedroom pays the difference itself unless the unit still passes the agency's rent-reasonableness test.

The 30% rule in New Castle

Housing is considered affordable when gross rent takes no more than 30% of gross household income. At the FY2027 2-bedroom FMR of $1,860, that means an income of about $74,400 a year — $22,320 of rent spread over twelve months. A 1-bedroom at $1,558 fits an income of $62,320, while a family-sized 4-bedroom at $2,445 needs $97,800. Remember that FMRs are gross rents: if a lease leaves utilities in the tenant's name, the housing agency applies a utility allowance so the combined cost is what gets compared with the payment standard. For workers, the 2-bedroom figure works out to about $36 an hour at full-time hours — a useful yardstick when weighing a job offer against local rent.

How New Castle, Delaware compares

Against its own state, New Castle's 2-bedroom FMR sits above the statewide ACS median gross rent of $1,530, and $231 (14%) above the Delaware county median.

The state's priciest county listing is New Castle at $1,860 and its least expensive is Sussex at $1,498, so New Castle sits near the top of the Delaware range.

Vouchers and Fair Market Rents in New Castle

This is a metropolitan rent area. In a small number of the largest metro areas HUD also publishes Small Area FMRs by ZIP code, which housing agencies in those areas must or may use for vouchers; the figures here are the standard area-wide schedule. For Housing Choice Voucher holders, the number that matters day to day is the payment standard: the local housing agency sets it between 90% and 110% of the FMR for each unit size, and the subsidy is calculated from the lower of that standard or the actual gross rent. An FMR is not a rent control and not a quote — homes in New Castle lease both above and below these figures — but it is the benchmark every voucher lease is tested against, and a good neutral summary of where the modest end of this market sits. The same figures apply in Bucks, Burlington, Camden, Cecil, Chester, Delaware and other parts of the same rent area.
