1st Advantage MortgageInvestors buying in Seaford, DE are measured on the rent the property earns. Locally, median gross rent is $1,176 and median real estate taxes are $1,151 a year, which together set how much loan a rent can carry.
Seaford rents, values and tenants
For Seaford, the latest five-year ACS shows a median gross rent of $1,176 (about 16% below the Delaware median of $1,401) and a median owner-occupied value of $224,300 (well below the Delaware median of $352,000). Dividing a year of median rent by the median home value gives a gross rent-to-value ratio of 6.3%, neither especially thin nor especially rich. It mixes apartments and houses, so treat it as a compass and not as the number for any one property.

50.5% of households in Seaford rent, well above the Delaware median of 27%. A large renter base supports steady leasing but also means plenty of competing listings. Median household income of $54,016 (well below the Delaware median of $84,954) sets the ceiling for rent growth, and 53% of renters already spend 30 percent or more of income on rent.
Housing stock and vacancy in Seaford
Seaford has a deep multifamily layer: roughly 35% of units sit in buildings of two or more, with 13% in duplexes through fourplexes. Homes here date to 1977 at the median, which is old enough to need system replacement but modern enough to avoid the worst surprises.
About 10% of Seaford's housing units are vacant, and the rental vacancy rate (units for rent against rented plus for-rent units) works out to 5.4%.
How investors should read Seaford
Seaford's 6.3% yield is workable. Expect most single-family rentals to land near the lender's minimum ratio, so details like taxes after reassessment matter. A median build year of 1977 suggests moderate repair budgets with the usual replacement cycles. A large renter population (50%) supports leasing, though it also means many competing landlords, so condition and price positioning count.
The payment side of the Seaford ratio
Property taxes in Seaford run a median $1,151 a year for owners, well below the Delaware median of $1,768. As a share of median value, that is about 0.51%. That is about 8% of a year of median rent gone to taxes before the loan is even counted.
