Home. Auto. Boat. Farm. One Agent Who Knows the Difference.
We're an independent agency in Kingsport — which means we shop multiple carriers to find coverage that fits how you actually live, not how a single company's product line is built.
Coverage for the Way People Live Around Here
East Tennessee isn't a one-size-fits-all place. You might own a home on a few acres, keep a boat on Cherokee Lake, drive a truck to work, and need an umbrella policy that covers all of it. A captive agent tied to one carrier often can't write all of that — or can't write it well.
We can. As an independent agency, we work with carriers including Progressive, Travelers, National General, and Hallmark, and we match each part of your coverage to the carrier that handles it best. Home, auto, boat, and farm — quoted and managed through one relationship, one phone call, one agent who knows your name.
Personal Insurance Coverage We Offer

Your home is probably your biggest asset. We make sure the coverage behind it reflects what it would actually cost to rebuild — not just what you paid for it. We work with carriers that understand regional construction costs, older homes, and rural property values across Northeast Tennessee and Southwest Virginia.
Homeowners Insurance

Whether you're commuting through Kingsport, driving mountain roads into North Carolina, or hauling equipment for work, we find auto coverage that matches how and where you drive. Multiple carriers means real rate comparison — not a single quote dressed up as a deal.
Auto Insurance

Cherokee Lake, Boone Lake, Watauga Lake — if you're on the water in East Tennessee, your boat deserves a policy written for it. We cover watercraft year-round, including liability, physical damage, and on-water towing, with carriers that actually specialize in marine coverage.
Boat & Marine Insurance

Your home and auto policies have limits. An umbrella policy picks up where they leave off — covering major liability claims that would otherwise come out of your savings. It's one of the most cost-effective coverages available, and most people don't have it.
Umbrella Insurance

Farm & Rural Property Insurance
Livestock, outbuildings, equipment, fencing, land — standard homeowners policies weren't built for any of that. We write farm and rural property coverage for clients across Northeast Tennessee and Southwest Virginia who need protection that reflects what they actually own.

Why Bundling Your Coverage Through One Independent Agent Makes Sense
Managing home insurance with one company, auto with another, and a boat policy somewhere else means three renewal dates, three billing portals, and three phone numbers when something goes wrong. We can often consolidate home, auto, and boat policies under compatible carriers — simplifying your coverage and, depending on carrier, qualifying you for multi-policy discounts in the process.
More importantly, when your policies are reviewed together, gaps are easier to catch. Coverage built in isolation rarely accounts for how your assets interact. We look at the full picture before we recommend anything.
We Review First. We Recommend Second.
A lot of people come to us with existing coverage they've never had anyone actually explain to them. Before we quote anything, we take a look at what you have, what you own, and how you use it. If your current coverage is solid, we'll tell you. If there are gaps — or if we can get you better protection at a better rate — we'll show you exactly what we're looking at and why.
That's what it means to work with an independent personal lines agent instead of a call center.
Frequently Asked Questions About Personal Insurance in Kingsport, TN
What's the advantage of using an independent agent for personal insurance instead of going direct?
An independent agent quotes from multiple carriers rather than one. That means you're comparing real options — different coverage terms, different rates, different carrier strengths — before you decide. You also get a person who manages your policies over time, not a new representative every time you call.
Can I bundle my home, auto, and boat insurance through the Mark Britt Agency?
In many cases, yes. As an independent agency, we work with carriers that write multiple personal lines, and we can often place home, auto, and boat coverage in a way that simplifies your account and may qualify for multi-policy pricing. We'll walk you through the options before recommending anything.
Do you write personal insurance for people in Virginia and North Carolina, or just Tennessee?
We serve clients across Northeast Tennessee, Southwest Virginia, and Western North Carolina. If you're in the Tri-Cities region — including Johnson City, Bristol, or Abingdon — or further out toward Boone, NC, we can help.
How do I know if my current coverage is enough?
The honest answer is that most people don't — not without someone reviewing it against what they actually own. We do that review as part of how we work with new clients. Bring us your current policies and we'll tell you what we see.
What personal lines carriers do you work with?
We work with carriers including Progressive, Travelers, National General, and Hallmark, among others. The right carrier depends on your property type, location, and coverage needs — which is exactly why we match clients to carriers rather than the other way around.
