Dover 4plexes: Buy a Fourplex and House Hack in Dover
Dover is Delaware's capital and its second-largest city, a government and military town built around The Green, the historic square where the state's early government met. About 40,592 people live here, the median household earns $60,199, and the typical home value is $342,473. Dover's figures in this guide use the Census Bureau's 5-year estimates, because the city is below the population threshold for 1-year estimates — the labels in the table say so plainly.
Dover by the Numbers
Dover's table runs on ACS 2024 5-year estimates, the honest basis for a city of 40,592. Median household income of $60,199 and a $342,473 typical home value sit near the middle of this batch, while median gross rent of $1,344 a month reflects a tenant market shaped by state government and Dover Air Force Base — steady employers that keep rental demand consistent across cycles.
| Population (Census Vintage 2025, July 1, 2025) | 40,592 |
|---|---|
| State capital | this city |
| Median household income (ACS 2024 5-year, B19013) | $60,199 |
| Households earning under $50,000 (ACS 2024 5-year, B19001) | 42.4% |
| Households earning $50,000 to $99,999 (ACS 2024 5-year, B19001) | 32.4% |
| Households earning $100,000 to $199,999 (ACS 2024 5-year, B19001) | 20.4% |
| Households earning $200,000 or more (ACS 2024 5-year, B19001) | 4.7% |
| Median gross rent (ACS 2024 5-year, B25064) | $1,344 per month |
| Median earnings, all workers 16 and older (ACS 2024 5-year, B20017) | $33,336 |
| Typical home value (ZHVI, September 2026) | $342,473 |
Twelve months at the $1,344 median rent comes to $16,128, which equals 4.71% of the $342,473 typical home value. Read 4.71% as a rough gauge of rent versus price in Dover, not as income — taxes, vacancies, and maintenance all reduce the owner's actual keep, and a single building's numbers will differ from the citywide gauge.

Buying a 4plex in Dover
Dover's fourplex stock is smaller and more scattered than in the bigger cities of this batch, so a buyer should be ready to look across the city rather than in one hot neighborhood. Buildings near the base, the state government complex, and Delaware State University draw the steadiest tenants; the buying edge comes from verifying rents and condition rather than from bidding speed.
Underwrite at the $1,344 median rent and at a lower case, and verify the legal unit count with the city before offering. In a smaller market, one long vacancy hurts more than in a big one, so favor buildings whose units are already leased at documented rents and whose owner unit needs no immediate major work.
Buyer Help and Loans in Dover
In a smaller market like Dover, lender familiarity with 2-4 unit files matters as much as rate. Ask which programs on the Loan Types page each lender closes for owner-occupied 2-4 unit purchases in Delaware, and whether they have experience with Dover appraisals and comparable sales.
Have the lender compare FHA and conventional on the same building, including mortgage insurance and reserve requirements, before you choose. The Loan Types page carries the program facts for that comparison, including the 5% minimum down on 2-4 unit conventional and HomeReady/Home Possible purchases.
Living in Dover
The Old State House stands on The Green in Dover — built in the 1790s, it was Delaware's seat of government for generations and now serves as a museum in the historic district.
Dover moves at a capital city's steady pace: legislative sessions, base activity, and university terms set the rhythm. An owner-occupant who buys a sound building, prices rents at what local households earn, and maintains the property steadily will find Dover's tenant base unusually loyal.
