What the heck is a Condex?
A Condo + Duplex = CONDEX
A condex is a type of two-unit residential building that looks like a duplex, but is legally set up as a condominium.
In other words:
-
It looks like a side-by-side single-family home
-
Each side has its own owner
-
Each unit is separately owned, financed, and taxed
-
There is usually no HOA or very minimal condo association
This property type is especially popular in New Hampshire, Massachusetts and York County Maine because they offer many of the benefits of single-family living without the price tag.
Condex vs. Condo — What's the Difference?
While a condex is legally classified as a condominium, it feels very different from a traditional condo. Condexes have no shared interior spaces, little to no HOA fees, and give owners the privacy and independence of single-family living. Traditional condos share common areas, charge monthly association fees, and come with more rules and restrictions.

A quick note on how this search works: every condex is legally classified as a condominium in the MLS, but not every condominium is a condex — the system has no separate "condex" category. These results are pulled from listings whose details specifically mention "condex," so it's possible (though rare) that a condex is listed without using that exact word.

How Is a this type of home different from a regular condo?
This is where condex homes really stand out:
For many buyers, a condex feels much closer to owning a single-family home than a typical condo.
What Are the Drawbacks of a Condex?
Condex homes offer a lot of advantages, but they're not the right fit for every buyer. Here's what to consider before you make an offer.
Shared wall with one neighbor. Unlike a traditional single-family home, a condex shares a common wall between the two units. Noise transfer can be a factor depending on construction quality and insulation.
Financing can be more complicated. Because a condex is legally classified as a condominium, FHA and VA loans require project-level approval — not just individual unit approval. Some lenders are unfamiliar with the process, so working with an experienced local lender matters.
Limited control over the other unit. You own your side, but you share a lot, a driveway, and sometimes a basement with your neighbor. If the other unit is a rental, tenant quality depends entirely on the other owner.
HOA documents may be minimal or missing. Many condex properties have little to no formal HOA structure. That can be a pro (no fees), but it also means fewer protections if a dispute arises with the neighboring owner.
Resale pool is smaller. Not every buyer understands what a condex is, which can affect days on market. The good news: in NH, condex literacy is higher than most states — buyers here are more familiar with the property type.
The bottom line: For the right buyer, the tradeoffs are minor compared to the benefits. The Dolloff Team has helped buyers navigate condex purchases across southern NH and the Seacoast — and we know exactly what to look for before you're under contract.
Are Condex Homes a Good Buy in NH?
Condex homes are one of the best-kept secrets in New Hampshire real estate. For buyers who want the privacy and feel of a single-family home but at a lower price point, a condex can be an excellent option. They are especially popular in southern New Hampshire towns like Exeter, Bedford, Derry, and Manchester where demand is high and single-family home prices have risen significantly.
Because each unit is separately owned and financed, buyers can use conventional loans, and in many cases FHA or VA loans — though FHA and VA financing may require additional approval steps.
If you're considering buying or selling a condex in New Hampshire or southern Maine, the Dolloff Team has deep experience with this unique property type and can guide you through every step.
New Hampshire has more condex properties per capita than most other New England states, making it a unique market for this property type. Towns like Derry, Londonderry, Hooksett, and Nashua have strong condex inventory, and they tend to sell quickly when priced well.
For sellers, a condex can attract a wider pool of buyers — including investors looking for rental income from the neighboring unit, or multi-generational families who want to live close but independently.

Can You Use an FHA Loan to Buy a Condex?
This is one of the most important things buyers — and even some mortgage lenders — overlook when purchasing a condex.
Because a condex is legally classified as a condominium, FHA treats it the same as any other condo project. That means the entire project must typically be FHA-approved before you can use an FHA loan — even if the condex is just two units.
FHA Single-Unit Approval (SUA)
If the project is not FHA-approved, don't panic. Lenders can request a Single-Unit Approval — sometimes called a "spot approval" — for an individual unit. This gives buyers more flexibility than many people realize, but it does require additional steps and not every lender offers it.
How to check FHA approval status:
You can search the HUD condominium approval database at entp.hud.gov to see if a specific project is approved, expired, or rejected.
What if it's not approved and SUA isn't available?
- You can still purchase with a conventional loan
- The condo association can apply for FHA approval, but it takes time
- VA loans have similar project approval requirements — always verify early
The bottom line: Always ask your lender about FHA approval status and Single-Unit Approval options before you make an offer. The Dolloff Team works with lenders who know this process inside and out.
How Do You Insure a Condex in NH?
Condex insurance is more complicated than most buyers expect — and getting it wrong can derail a closing.
The Master Policy Requirement
Under federal lending guidelines, every condominium project — regardless of size — is required to have a master insurance policy. That includes two-unit condexes. There is no size exemption.
Here's the problem: many NH condexes, especially older ones, were created informally and have never had a master policy in place. Each owner just carries their own homeowner's policy. That feels like enough — until a buyer tries to purchase one of those units with a mortgage. At that point, the lender requires proof of a master policy, and if one doesn't exist, the closing can stall or fall apart entirely.
What a master policy typically covers:
- The building structure and exterior
- Common areas including shared driveways and yards
- Shared walls and roof
What each unit owner still needs individually:
- Dwelling coverage for their unit's interior
- Personal property coverage
- Liability coverage
- Loss of use coverage
Before you make an offer on a condex, ask your agent to verify whether a master policy exists. The Dolloff Team knows to check this as part of every condex transaction — it's one of the things that can make or break a closing.
Frequently Asked Questions About Condex Homes
What is the definition of a condex?
The condex definition is often misinterpreted. A condex is a two-unit residential building structured as a condominium. Each unit is separately owned, financed, and taxed. The word condex comes from combining condo and duplex.
What is the meaning of condex?
Condex means condominium duplex — a property that looks like a duplex from the outside but is legally set up as a condominium with two separate owners.
What is a condex home?
A condex home is a side-by-side two-unit property where each unit has its own deed, its own mortgage, and its own tax bill. There are no shared interior spaces and usually no significant HOA fees.
How is a condex different from a condo?
A condex has no shared common areas, minimal or no HOA fees, and feels much more like a single-family home. A traditional condo shares hallways, parking, amenities, and common areas with other owners and charges monthly association fees.
Are condex homes common in New Hampshire?
Yes — New Hampshire has more condex properties per capita than most New England states. Towns like Derry, Manchester, Londonderry, Hooksett, Exeter, and Salem have strong condex inventory.
What are the disadvantages of buying a condex?
The main drawbacks include a shared wall with one neighbor, more complex FHA/VA financing requirements, limited control over the adjoining unit, and a smaller resale pool compared to single-family homes. The Dolloff Team has helped buyers navigate condex purchases across southern NH and the Seacoast — and we know exactly what to look for before you're under contract.
Can you rent out a condex unit? Yes. Each unit is separately deeded, so the owner can rent it out but check with the HOA rules. Some buyers purchase both units and rent one side to help offset their mortgage.
What is the difference between a condex and a duplex? A duplex is owned by a single investor who owns both units. A condex has separately deeded units that can be individually purchased and financed — often with conventional, FHA, or VA loans. This makes condex ownership accessible to individual buyers, not just investors.
