A mortgage calculator for Delaware estimates the full monthly cost of a Delaware home loan: principal and interest from standard amortization, plus property tax, homeowners insurance and private mortgage insurance (PMI) when you put down less than 20%. It also shows the realty transfer tax, usually 4% in total (2.5% state plus up to 1.5% local), which buyer and seller split equally by law.
How the Mortgage Calculator Delaware Formula Works (Worked Example)
Principal and interest use the standard amortization formula M = P × r(1+r)n ÷ ((1+r)n − 1), where P is the loan amount, r the monthly rate (annual rate ÷ 12) and n the number of payments. Property tax is the home price × your local rate ÷ 12, insurance is your annual premium ÷ 12, and PMI is the loan amount × your PMI rate ÷ 12. Example: a $370,000 Delaware home, 10% down, 30-year fixed at a user-entered 6.5% (click Load Example above to reproduce it).

Delaware Property Tax Rate and Your Monthly Payment
Delaware has no state property tax. Counties, school districts and some towns levy it. The Tax Foundation (Property Taxes by State and County, 2026 edition, from Census American Community Survey data for 2020–2024) puts the statewide effective rate at about 0.54% of owner-occupied home value. All three counties completed a court-ordered reassessment for the 2025 tax year, which reset assessed values and tax rates, so use the current rate for your parcel from the county or the listing.
| Local rate | Annual tax on $370,000 | Added to monthly payment |
|---|---|---|
| 0.41% | $1,517 | $126.42 |
| 0.54% (statewide default) | $1,998 | $166.50 |
| 0.81% | $2,997 | $249.75 |
Delaware Closing Costs: Realty Transfer Tax
Delaware has one of the highest transfer taxes in the country. The state realty transfer tax is 2.5% under 30 Del. C. § 5402, and counties or towns may add up to 1.5%, for a total of 4% in most places. By law the tax is split equally between buyer and seller unless they agree otherwise. Qualifying first-time home buyers get the buyer’s share reduced by 0.5% of the value up to $400,000, a credit of up to $2,000 (Delaware Division of Revenue). The calculator shows the full 2% each side and does not apply that credit.
| Delaware item | Amount | Usually paid by |
|---|---|---|
| State realty transfer tax (30 Del. C. § 5402) | 2.5% of value | Split equally |
| County / town realty transfer tax | Up to 1.5% — 4% total gives $7,400.00 each side on $370,000 | Split equally |
| First-time home buyer credit | 0.5% of value up to $400,000 (max $2,000) off the buyer’s share | Reduces buyer’s cost |
| Escrow deposits for tax and insurance | Set by your lender — see your Loan Estimate | Buyer |
| Lender, appraisal and title charges | Vary by lender and title company — compare Loan Estimates | Negotiable |
Some costs are negotiable, and sellers sometimes cover part of a buyer’s closing costs as a concession.
How Delaware Mortgage Rates Affect Your Payment
Rates in Delaware follow national mortgage markets and vary by lender, credit score, down payment and loan type. The 6.8% default is an example rate, not a quoted average. On a $370,000 home with 20% down, it produces a monthly principal and interest payment of about $1,930. A 0.25% rate increase adds roughly $50 to that payment, so shopping multiple lenders can save thousands over the life of the loan.
Adjustable-rate mortgages (ARMs) often start lower but carry rate-reset risk. FHA loans (3.5% down), VA loans (0% down for eligible veterans) and USDA loans (0% down in eligible rural areas) are alternatives to a conventional loan in Delaware.
First-Time Buyer Programs in Delaware
The Delaware State Housing Authority (DSHA) offers first mortgage programs and down payment and closing cost assistance for eligible buyers. Check DSHA for current income and price limits.
FHA loans are available nationwide with 3.5% down for borrowers with a 580+ credit score. VA loans require no down payment and no PMI for qualified veterans and service members.
If your down payment is below 20%, PMI on a $333,000 loan adds about $167/month at a 0.6% annual rate. The Urban Institute puts typical PMI at roughly 0.46%–1.5% of the loan per year depending on credit score. PMI can be removed once your loan-to-value ratio reaches 80%, so extra payments accelerate the timeline to dropping PMI.
