- Baboosic Lake and the Souhegan River bring flood questions to some properties.

Three kinds of Amherst home
Amherst’s village, with its green and white clapboard houses, holds some of the most carefully kept antique homes in southern New Hampshire. Outside the village, the town spreads into horse properties and newer colonials on multi-acre lots. Around Baboosic Lake, seasonal cottages have become year-round homes. Each needs a different starting point.
Village antiques
Timber frames, plaster and wavy glass. Rebuild cost often runs well above a typical house of the same size.
Horse and hobby farms
Barns, run-in sheds and fences. Outbuildings need their own limits; boarding needs a separate review.
Baboosic Lake
Converted camps and new lake homes. Distance to water and docks drive the questions.
Wooded new builds
Large homes on private wells. Fire department distance and hydrants matter.
Restoring a historic Amherst house after a loss
Inside the historic district, exterior work generally needs Historic District Commission review (Town of Amherst, Historic District Commission). If a fire or a falling tree damages a 1790s house, putting back period clapboards, trim and windows costs more than standard materials. We look at three parts of the policy together: a dwelling limit built from a replacement cost appraisal, ordinance or law coverage for the code work that a major repair triggers, and additional living expense long enough for a careful restoration. Our older and historic home insurance page explains each.
Lake homes and flood
Baboosic Lake and the Souhegan River put some Amherst homes near mapped flood zones. Check your address on the FEMA Flood Map Service Center. A homeowners policy excludes flood, so lake and river owners should weigh NFIP flood or private flood, which may offer higher building limits and coverage for finished basements that NFIP restricts.
Carriers we compare in Amherst
For an antique Amherst house the question is often which carrier is comfortable with the age and systems; for a new lot-line colonial it is which form handles the rebuild figure best. Hanover can write homes up to $2 million, Andover fits New Hampshire homes up to $1.5 million, and National General and Openly reach further, with Openly writing up to $5 million in New Hampshire. Cincinnati and Chubb take the largest homes. Read our Chubb review for how one of those forms works.

Amherst high-value home insurance FAQs
Which carriers write high-value homes in Amherst, NH?
For Amherst, the choice often turns on the age of the house. Hanover writes homes up to $2 million, Andover fits New Hampshire homes up to $1.5 million, and National General and Openly (up to $5 million in New Hampshire) add options. The largest homes go to Cincinnati or Chubb.
I own an antique house in Amherst Village. What should my policy include?
An accurate replacement cost for period materials and craftsmanship, ordinance or law coverage for code upgrades, and enough additional living expense for a long restoration. Because the Historic District Commission reviews exterior changes in the district, repairs may need approval and matching materials.
Does a Baboosic Lake home need flood insurance?
Look it up on the FEMA flood map, then think about where water could actually reach. Homeowners policies exclude flood. We can quote NFIP flood and private flood from Neptune, Beyond Floods, Flow Flood, Aon Edge, CatCoverage and The Flood Insurance Agency.
My Amherst home has a barn and outbuildings. Are they covered?
Detached structures fall under other structures, usually a share of the dwelling limit. An old barn, carriage house or large garage can be worth more than that, so we raise the limit or schedule it. A barn used for a business or for boarding horses needs its own review.
Is an older wood stove or oil heat a problem for carriers?
Carriers ask about wood stoves, chimneys, oil tanks and older wiring in Amherst’s older homes. Updated systems, inspections and documentation make underwriting smoother and open up more carriers.
Do you have an office in Amherst?
No. We serve Amherst from our Portsmouth office by phone, email and video. Most of our high-value work is done that way, with carrier appraisers visiting the home when needed.
