New Hampshire's Seacoast is small on the map and big on variety. The coastline runs only about 13 miles, from the Massachusetts line at Salisbury to the Piscataqua River and the Maine border at Kittery. Yet within a short drive you can choose between a historic seaport city, a tiny island town, beach towns, a classic New England town with a famous academy, and the region's largest city. For homebuyers, that range is both the appeal and the challenge.
Spring is a natural time to start looking. You can see properties without snow, walk the neighborhoods, and get a feel for the coast before the summer crowds. This guide covers the main Seacoast towns, what coastal buyers should check, how to choose an agent, and six local real estate offices.
This is a general guide, not financial or legal advice. For prices, taxes and current market conditions, talk to a local agent and check official sources.
Getting to know the Seacoast
The Seacoast Region is the southeastern part of New Hampshire, centered on Portsmouth. It includes eastern Rockingham County and southern Strafford County. Most definitions also include inland towns such as Dover, Rochester, Durham and areas as far west as Epping.
Portsmouth. Portsmouth is a historic seaport on the Piscataqua River, with about 22,000 people at the 2020 census. It is a popular summer destination, and the former Pease Air Force Base is now Portsmouth International Airport at Pease.
New Castle. New Castle is the easternmost town in New Hampshire and the smallest by area. It is the only town in the state located entirely on islands, and it is home to Fort Constitution, Fort Stark, the New Castle Common and the historic Wentworth by the Sea hotel. It had about 1,000 residents at the 2020 census.
Rye. Rye, with about 5,500 residents, is home to several state parks along the Atlantic coast.
Hampton. Hampton had about 16,200 residents at the 2020 census and is home to Hampton Beach, a well-known summer destination.
Exeter. Exeter, with about 16,000 residents, is home to Phillips Exeter Academy. The town sits where the Exeter River becomes the tidal Squamscott River.
Dover. Dover, in Strafford County, had about 32,700 residents at the 2020 census, making it the most populous city in the Seacoast region.
What coastal buyers should check
Buying near the ocean brings questions that inland buyers may not face.
Flood zones and insurance. Some coastal and low-lying properties sit in flood zones. Ask your agent and insurance agent early, since flood insurance can affect your budget.
Seasonal neighborhoods. Beach areas can feel very different in July than in January. Visit in more than one season if you can, and ask about parking and traffic in summer.
Older homes. Portsmouth, Exeter and Dover have many historic homes. They are full of character but can need work on wiring, foundations and windows. A thorough inspection matters.
Commutes. Many Seacoast residents commute to other parts of New Hampshire, Massachusetts or Maine. Test your drive at the time of day you would make it.
Rentals and second homes. Some beach properties are used as summer rentals. If that is part of your plan, ask about local rules before you buy.
How to choose a local agent
The Seacoast towns differ a lot from each other, so an agent who knows your target towns is valuable. When you talk to agents, ask:
- Which towns do you work in most often?
- How do you handle coastal issues such as flood zones?
- Can you recommend local inspectors, lenders and attorneys?
- How do you communicate, and how fast do you respond?
- What do buyers new to the Seacoast most often overlook?
Some Seacoast offices are independent and local, and some are part of larger regional or national groups. Both can serve buyers well. Focus on the individual agent's knowledge and how well you communicate.

The buying process in brief
1. Get pre-approved. A lender's pre-approval sets your budget and strengthens your offer.
2. Narrow your towns. Visit Portsmouth, the beach towns, Exeter and Dover. They feel very different.
3. Choose an agent. Interview a few with the questions above.
4. Tour and make an offer. Your agent will advise on contingencies, including inspections.
5. Inspect and insure. Get a full inspection and check flood insurance needs early.
6. Close. Your agent, lender and attorney or title company will guide the final steps.
Living on the Seacoast
The Seacoast gives you the ocean, historic downtowns, and easy access to Maine and Massachusetts, all in a compact area. Residents can walk to the water in one town and be in a small-city downtown ten minutes later. The trade-offs include summer traffic in beach areas and the extra questions that come with coastal property. For many buyers, the lifestyle is worth it.
If you are relocating, spend a weekend here in the off-season as well as in summer. Walk Market Square in Portsmouth, drive Route 1A along the coast, and look around Exeter and Dover. Seeing the region in more than one mood is the best way to know where you will be happy.
