Rental Market in Sebastian, Florida

The median gross rent in Sebastian was $1,451 a month in the Census Bureau's ACS 2020-2024 estimates, up from $1,050 in 2015-2019, and HUD's fiscal 2026 fair market rent for a two bedroom unit in the Indian River County metro is $1,604.

Gross rent in the Census count is contract rent plus utilities and fuels the tenant pays. For the City of Sebastian it was $1,451 in the 2020-2024 estimates (Census Bureau) and $1,050 in the 2015-2019 estimates (Census Bureau), an increase of about 38 percent between the two surveys. Because the survey pools five years of responses, the newest figure still includes leases signed in 2020 and 2021, before most of the post-pandemic rent increases reached renewals.

HUD's fair market rents give a second official benchmark used for housing vouchers. For fiscal year 2026 the Sebastian-Vero Beach-West Vero Corridor metro, which is all of Indian River County, has fair market rents of $1,222 for a one bedroom and $1,604 for a two bedroom unit (HUD). HUD built the 2026 figures from a 2019-2023 ACS base rent of $1,199 for a standard two bedroom unit and then adjusted it for recent movers and inflation.

The FY 2026 table shows small units getting slightly cheaper and larger units more expensive. The efficiency and one bedroom standards fell by $25 and $24, while the two bedroom rose $37 and the four bedroom $90. For Sebastian, where most rentals are houses, the larger unit standards are the relevant ones.

About 15 percent of Sebastian's occupied homes are rented: 1,718 of 11,586 households in the ACS 2020-2024 estimates, a share that has barely moved since 2015-2019.

The Census Bureau counts 9,868 owner households and 1,718 renter households in Sebastian in the 2020-2024 estimates (Census Bureau). In the 2015-2019 estimates the count was 8,141 owners and 1,641 renters (Census Bureau), so nearly all of the growth in occupied homes went to owners. Sebastian is a city of owners, and its rentals are mostly houses.

Few rentals sit empty. The same survey counts 80 vacant units for rent in Sebastian against 843 vacant units held for seasonal, recreational or occasional use (Census Bureau). The seasonal figure, more than ten times the for-rent count, reflects winter residents and second homes that stand empty part of the year, and some of those homes enter the short term rental market in season.

Renters in Sebastian are also more recent arrivals than owners. The median year a renter householder moved into the current home was 2017 in the 2020-2024 survey, compared with 2012 for owners (Census Bureau).

Most Sebastian renters are cost burdened: in the ACS 2020-2024 estimates 969 of the 1,581 renter households with a computed ratio, about 61 percent, spent 30 percent or more of income on rent, and 556 spent half or more.

The Census Bureau's table of gross rent as a percentage of household income shows 556 Sebastian renter households paying 50 percent or more of income in the 2020-2024 estimates, out of 1,718 renter households, 137 of which had no computed ratio (Census Bureau). In the 2015-2019 estimates, 314 households were at 50 percent or more, and about 41 percent of renters with a computed ratio paid 30 percent or more (Census Bureau).

The median tells the same story. The median Sebastian renter household spent 39.2 percent of income on gross rent in the 2020-2024 estimates (Census Bureau), up from 25.5 percent in 2015-2019 (Census Bureau). Rent rose about 38 percent between the two surveys, while median household income in Sebastian rose about 29 percent, and renter incomes in a city with a median age of 58 include many fixed retirement incomes.

Sebastian has the highest median gross rent among Indian River County's cities in the ACS 2020-2024 estimates, at $1,451, but sits below Palm Bay and Melbourne just across the Brevard County line.

North of the county line, Palm Bay's median gross rent was $1,601 (Census Bureau) and Melbourne's $1,525 (Census Bureau), while Micco, the unincorporated Brevard community that borders Sebastian on the north, came in at $1,430 (Census Bureau). Vero Lake Estates, west of the city in Indian River County, posted $2,094, but with a margin of error of $280 on a small number of renter households (Census Bureau). Sebastian renters who work in Brevard County therefore face rents similar to or higher than at home if they move closer to their jobs.

The county median of $1,357 (Census Bureau), the City of Vero Beach median of $1,221 (Census Bureau) and Fellsmere's $1,158 (Census Bureau) all sit below Sebastian. The difference comes largely from what is rented. In Sebastian, 1,274 of the 1,718 renter occupied homes in the 2020-2024 estimates were detached single family houses, about 74 percent, and only 94 were in buildings of five or more units (Census Bureau). Another 142 were in two unit buildings, the duplexes common on Highlands lots, and 129 were mobile homes.

Bedroom counts follow the building type. Of Sebastian's renter households, 885 lived in three bedroom homes and 569 in two bedroom homes, while only 147 rented one bedroom units and none rented efficiencies (Census Bureau). HUD's fiscal 2026 fair market rent for a three bedroom unit in the metro is $1,956, which is closer to what a typical Sebastian rental lease covers than the one bedroom benchmark.

Sebastian homes rented for six months or less owe Indian River County's 5 percent tourist development tax, and the City of Sebastian Building Department handles a vacation rental application package for owners.

The Indian River County Clerk of the Circuit Court states that anyone who offers accommodations for short term rental of six months or less must collect tourist development tax from the guest, at 5 percent of total taxable rental receipts, in addition to state sales tax, and file by the 20th of the month after collection (Indian River Clerk). Owners or agents keep a collection allowance of 2.5 percent of the tax, up to $30. Owners who rent only in winter must still file zero returns for other months unless they ask in writing for inactive status.

At the city level, the Building Department lists a vacation rental application package among its services, alongside permits and business tax receipts (City of Sebastian). The application is the city's record of which Sebastian homes operate as vacation rentals.

Demand for those rentals has grown. Vero Beach 32963 reported in October 2025 that hotel rentals in Indian River County were down slightly in summer 2025 while more visitors chose vacation rentals than the year before (Vero Beach 32963). For Sebastian, the 843 seasonal units counted by the Census Bureau are the pool from which most of these short term rentals are drawn, alongside homes owned by year round landlords.
