What NH Law Actually Requires When You Sell a Duplex
The short answer is that New Hampshire does not require you to notify tenants that you are selling a standard duplex. There is no statute mandating that you inform occupants of a pending sale, an accepted offer, or a closing date when the property is a conventional two-unit residential building.
This surprises many owners, particularly those who have heard about tenant right-of-first-refusal laws in other states. New Hampshire has no such requirement for standard duplexes. Your tenants have no statutory right to purchase the property before you sell it to a third party, and you have no obligation to disclose the sale to them as a condition of completing the transaction.
What does transfer automatically is the lease itself. When title changes hands, every existing lease, whether fixed-term or month-to-month, becomes binding on the new owner by operation of law. Tenants do not need to sign new agreements, and they do not need to be notified of the ownership change to preserve their rights. The lease follows the property, not the landlord.
This matters for your sale in a practical way. Buyers who understand this rule will not expect vacant units as a condition of closing unless you negotiate that separately. Sellers who understand it can market occupied units honestly, without worrying that tenants have any legal mechanism to block or delay the transaction.
For a broader look at how tenant-occupied units affect valuation and buyer interest, the article on NC multifamily rent roll red flags that kill deals covers the documentation side of this issue in useful detail, even though it focuses on a different state.
The Manufactured Housing Park Exception and Why It Matters
There is one category of property where New Hampshire law does impose a formal notification requirement: manufactured housing parks. If your duplex is located within a manufactured housing park, or if the structure itself involves mobile or manufactured homes on a shared-infrastructure lot, RSA 205-A:21 applies.
Under that statute, a park owner must provide 60 days' written notice to each tenant before accepting a purchase offer. The notice must be delivered by certified mail and must include the sale price and the material terms of the proposed transaction. This gives tenants an opportunity to organize a collective purchase if they choose to pursue one.
The exceptions to this rule are narrow but important. The 60-day notice requirement does not apply if the sale results from foreclosure, if the transfer is to a family member, or if the parties are joint tenants conveying to one another. Outside those carve-outs, the rule is firm.
Most owners of standard duplexes, meaning two-unit buildings on a single lot with conventional construction, fall entirely outside RSA 205-A:21. However, if your property has any characteristics that could create ambiguity, such as prefabricated construction, shared utility infrastructure with adjacent lots, or a deed that references park-style ownership, it is worth confirming your classification with a local real estate attorney before you begin marketing. Misclassifying the property and skipping the required notice could expose you to a claim that the sale was improper.
Showing Access Rules That Apply During Any NH Sale
Even though you do not need to notify tenants about the sale itself, you do have a legal obligation when it comes to entering occupied units for showings and inspections. RSA 540:9 establishes that landlords must provide reasonable notice before entering a tenant's unit. In practice, 24 to 48 hours is the accepted standard in New Hampshire.
This rule applies regardless of the reason for entry. Whether you are bringing a prospective buyer through the unit, scheduling a home inspection, or conducting an appraisal walkthrough, you need to give tenants advance notice. Failing to do so is not a minor procedural issue. It can be treated as a violation of tenant privacy, and a tenant who feels their rights were ignored may become uncooperative at exactly the moment you need access for due diligence.
A few practical steps make this easier:
- Provide written notice (text message or email works in most cases) and keep a record of it.
- Schedule showings at times that minimize disruption to tenants' routines.
- Communicate the general purpose of the visit without disclosing more than necessary about the sale timeline.
- Coordinate with your buyer's agent or the buyer directly so that inspection windows are consolidated rather than spread across multiple separate visits.
Buyers conducting due diligence on your property will want access to both units, ideally during a single scheduled window. Organizing this efficiently signals that you are a professional seller and that the tenants are manageable, both of which support buyer confidence. You can find a detailed breakdown of what buyers typically review during this phase in the article on small multifamily due diligence: what serious NC buyers actually review.
Security Deposit Transfer: Obligation, Process, and Buyer Expectations
When you sell a duplex, you are required to transfer all tenant security deposits to the buyer at or before closing. This is not optional. The deposits belong to the tenants, held in trust by whoever owns the property. When ownership changes, so does the custodial responsibility.
The transfer typically happens one of two ways. Either the deposits are credited to the buyer at closing through an adjustment on the settlement statement, or they are transferred directly from your account to the buyer's designated account before closing. Your purchase and sale agreement should specify which method applies, and both parties should confirm the amounts match the lease documents.
Tenants should be informed of who now holds their deposit and how to reach the new owner or manager. This is not a strict statutory mandate for standard duplexes in the same way the manufactured housing park notice is, but it is a best practice that prevents disputes. A tenant who does not know where their deposit went is a tenant who may file a complaint or withhold cooperation during the transition.
From a buyer's perspective, unresolved security deposit questions are a red flag. Serious investors will ask for copies of all deposit receipts and confirmation that the amounts on file match what tenants were charged. If your records are incomplete, resolve that before you go to market. Buyers who find discrepancies during due diligence will either renegotiate the price or walk away.
How Lease Continuity Affects Your Sale Price and Buyer Pool
Lease continuity is a feature, not a complication, when you market a duplex to the right buyer. An investor purchasing a two-unit property with tenants already in place is acquiring immediate cash flow. They do not need to find tenants, screen applicants, or carry vacancy costs while the property sits empty. That has real value, and it should be reflected in how you present the property.
The key is documentation. Buyers will want to see the actual lease agreements, not just a summary. They will want to confirm the rent amounts, the lease expiration dates, any renewal options, and whether there are any side agreements or concessions that are not reflected in the written lease. If you have been collecting rent informally or have allowed a tenant to pay below market without a written amendment, that needs to be disclosed and explained.
Month-to-month tenancies are a different consideration. A buyer who wants to reposition the property, raise rents to market rate, or eventually occupy one unit will view a month-to-month tenancy as flexibility. A buyer who wants long-term stability may prefer a fixed-term lease with 12 or more months remaining. Knowing your buyer's profile helps you frame the tenancy correctly in your marketing materials.

Occupied duplexes in New Hampshire sell best when the seller can hand a buyer a clean package: current leases, deposit records, rent payment history, and a clear explanation of any tenant-related issues. Buyers who already understand lease continuity rules are not slowed down by the presence of tenants. They price the cash flow, confirm the documentation, and move to close.
