A Delaware mortgage payment starts with the same formula as anywhere in the country, then picks up two costs that vary sharply by state: property tax at an effective 0.47% and homeowners insurance near $1,100 a year. On a typical Delaware home of $405,000, those two add $250 to every monthly payment before the loan costs anything. The tool below is preloaded with that home, 10% down, and a 30-year fixed rate of 6.25%.

What changes the payment in Delaware
Property taxes in Delaware
The school property tax is capped at 10% of a primary residence's assessed value; investment properties receive no cap. At the statewide effective rate of 0.47%, the example home pays $1,900 a year, $158 of every monthly payment. Local rates inside Delaware vary well beyond the statewide figure, so take the number from the county assessor or the listing for any home you consider.
Homeowners insurance in Delaware
Budget roughly $1,100 a year. Hurricane and flood exposure dominates along the Gulf and South Atlantic coasts: windstorm deductibles, separate wind pools, and NFIP flood policies can add thousands per year, and lender-required coverage tightens within a few miles of the shoreline. Lenders require coverage before closing, and the premium is collected monthly in escrow, so get a quote before you make an offer.
How far a Delaware income goes
The median Delaware household earns about $87,534 a year. Under a 28% housing limit that supports a payment of $2,042, $604 short of the example. The Delaware edition of the home affordability calculator solves for the price that income supports.
How to estimate your Delaware mortgage payment
- Replace the example price with the home you are considering. The property tax figure won't update by itself; recalculate it from the listing or the county's rate.
- Enter your real down payment. Under 20% on a conventional loan, PMI is added until the balance reaches 78% of the price.
- Use a rate from a current loan estimate rather than an advertised rate, which often assumes points paid up front.
- Replace the $1,100 insurance estimate with a quote for the specific address.
- Add HOA dues if the home has them, then try extra principal to see how much interest an early payoff saves.
Methodology
Principal and interest use the standard fixed-rate amortization formula, M = L × r ÷ (1 − (1 + r)^−n). Property tax is the statewide effective rate applied to the example price; insurance is a typical statewide premium. PMI is charged at the stated annual rate until the balance first reaches 78% of the original price, when the Homeowners Protection Act requires it to be cancelled.
