Due Diligence in New Hampshire

A Seller & Buyer’s Guide

Buying or selling a home isn’t just about pretty pictures and open houses — it’s about making sure all the details behind the scenes line up. That’s where due diligence comes in. In New Hampshire, this step is critical. It protects both sides, smooths out surprises, and keeps the closing table from feeling like a courtroom.

1. Title & Legal Check (a.k.a. “Who really owns this place?”)

We confirm the property is free of liens, disputes, or quirky deed restrictions that could derail a sale. Think of it as a background check for the house — better to know before you fall in love.

2. Inspections & Tests

The classics: home inspection, septic check, water quality, radon, pests. For waterfront or rural properties, we add in environmental tests (shoreline rules, wetlands, soil). Buyers want reassurance, sellers look smart for being upfront.

3. Seller Disclosures (be honest, be golden)

In NH, sellers must disclose known material defects — roof leaks, old septic issues, heating gremlins, you name it. Full transparency builds trust and saves headaches later. Think of it as “dating honesty” for houses: it always comes out eventually.

4. Zoning & Land Use

Every town has its quirks. Setbacks, shoreland protection, or whether you can build that dream barn. Buyers need to know; sellers earn points by sharing the info early.

5. Taxes, Assessments & Costs

It’s not just the sticker price. Buyers want to understand property taxes, assessments, and expected upkeep. Sellers shine by handing over a neat package with history, utility bills, and repair receipts.

6. Environmental Matters

Radon, mold, lead paint (for older homes), buried oil tanks, flood zones. It’s not glamorous, but ignoring it could tank a deal faster than you can say “closing date.”

7. Surveys & Boundaries

Good fences make good neighbors, and good surveys prevent lawsuits. Making sure lot lines are crystal clear avoids future “that’s my tree!” debates.

8. Financing & Contract Contingencies

Buyers need clear timelines for inspections and financing approvals. Sellers? It’s about knowing exactly when a buyer can back out, and when the deal is locked in.

9. Final Walk-Through

One last lap before the keys change hands. Buyers make sure the house is as promised; sellers get to prove they’ve delivered. Smooth hand-off = happy ending.

Everything we’ve shared here is based on our best knowledge, experience, and what makes sense in today’s New Hampshire market. But real estate, like the weather, has a way of changing on us. Rules, regulations, and best practices may shift over time — so while this guide is a trusty compass, it’s not carved in granite. When in doubt, always check with your attorney, inspector, or local zoning board before making big decisions.
