Coastal Delaware offers a number of things its neighboring states do not, primarily ultra low taxes and ocean front properties. 
If you live in Washington DC or PA there is no ocean front property available. If you live in Maryland, New Jersey, New York or Virginia your property taxes are sky high.
How low are Delaware taxes? An ocean front home in New Jersey may have property taxes of $20,000 a year or more. The same house on a similar beach in Delaware may have property taxes of $1000 or less making Coastal Delaware Homes one of the best deals in the country.
