Selling a Tenant-Occupied Two-Family in Brooklyn

A few days ago, an owner of a Brooklyn two-family called me with a familiar knot: the tenants wanted to sign new leases, and he was weighing whether to renew or put the building on the market. He worried that committing to another term would box him out of a sale. My answer surprised him — the leases themselves weren't the problem. The terms, the rents, and the regulatory status of those units were.

What most small landlords miss when they're planning to sell is that the lease is part of the asset. It shapes who will buy your building, what they'll pay, and how quickly the deal can close. In this case, the tenants had been there more than two years, so the owner also needed to get the notice period right. If that notice is late, the existing tenancy may continue on its current terms until the required notice period expires, disrupting the timing of a planned sale.

The buyer-pool tradeoff: owner-occupants versus investors

The buyer pool for a two-family splits into two very different audiences, and the lease decides which one shows up. Owner-occupants usually want a home they can move into — they often prefer vacant units so they can set their own terms, or they bid low knowing they may need to wait out a lease. Investors buy buildings for the income stream, and a tenant-occupied property can be attractive to an investor when the lease terms, payment history and rent support the property's income.

That is the tradeoff I walked this owner through. A long, below-market lease can shrink his buyer pool and may reduce what an income-focused buyer is willing to pay, because an investor has to underwrite the building on the rents that are actually in place. If those rents sit well beneath the market, the price the building can support drops with them. The lease is not a side detail you handle after deciding to sell — it is a primary input into what the marketing and the eventual bid will look like.

The 5% cap misconception and the 2026–27 0% guideline

The owner believed New York City capped every rent increase at 5% and that the mayor's rent freeze applied to his two-family. Neither is true as a blanket rule. A 0% guideline applies to covered rent-stabilized leases, and it does not apply automatically to every privately owned rental in the city (NYC Rent Increase Guide).

The Rent Guidelines Board adopted a 0% guideline for covered rent-stabilized one- and two-year leases beginning October 1, 2026 through September 30, 2027. To know whether a unit is actually covered, the landlord must verify the building's status — a building with six or more units built before 1974 can indicate possible rent stabilization, but apartment status must be confirmed, not assumed. A two-family in Brooklyn often falls outside this frame entirely, which is why assuming the guideline applies is a costly mistake.

The first question is whether the unit is rent stabilized. If it is not, the Rent Guidelines Board's 0% guideline does not apply—but that does not end the analysis. The landlord must still determine whether the Good Cause Eviction Law applies and comply with the applicable notice requirements. For a qualifying small landlord whose unit is exempt from Good Cause, there is no universal 5% cap on the proposed rent at the end of a lease.

The notice periods under New York Real Property Law 226-c

New York Real Property Law section 226-c requires written notice when a landlord proposes a rent increase of at least 5% or does not intend to renew the tenancy (NY RPL 226-C). The amount of notice is based on cumulative occupancy or lease length, whichever produces the longer notice: 30 days when occupancy is under one year and there is no lease term of at least one year; 60 days when occupancy is more than one year but less than two years, or the lease term is at least one year but less than two years; and 90 days when the tenant has occupied the unit for at least two years or holds a lease of at least two years (NYC Rent Increase Guide).

In this owner's case, the tenants had lived in the building for more than two years, so the applicable notice period was at least 90 days. That matters for timing a sale: if you renew on the wrong cadence, a rent increase stalls right as you are trying to line up a closing. If timely notice is not provided, the existing tenancy continues on its current terms until the required notice period has expired.

One caution before you act on section 226-c: the statute governs the notice itself, but the rent that sits behind that notice still depends on whether the unit is regulated. For a rent-stabilized apartment the rent is set by the board's guidelines, not by the market. An existing lease generally cannot be changed during its term without agreement. For an unregulated tenancy, the required notice may allow a landlord to propose a new rent, but the tenant still must agree to the new terms; notice by itself does not create a new lease (NYC Rent Increase Guide).

The Good Cause Eviction Law's small-landlord exemption

The Good Cause Eviction Law generally exempts a small landlord who owns 10 or fewer housing units throughout New York State (NY AG Good Cause Guide). The key phrase is "throughout New York State." Ownership is counted across your whole portfolio, so a building here plus units elsewhere can push you past the threshold even if the property in question is small.

The law also looks through the ownership structure. When an entity owns the property, the law examines the natural people with direct or indirect ownership interests in that entity or an affiliated entity. If any such owner exceeds the applicable unit threshold — or the ownership information cannot be provided — the small-landlord exemption may not apply.

The required Good Cause notice must be included with an initial lease, renewal lease and certain other statutory notices. It must state whether the unit is covered and, when the unit is exempt, identify the applicable exemption. This disclosure is not optional boilerplate (NY RPL 231-C).

Why an attorney should review the status before you sign

Distinguishing the unit's regulatory status, the 90-day notice, and the Good Cause exemption is not something to guess at, and it is not something a broker resolves. What I did for this owner was help him identify the relevant rules and official guidance. The actual determination — whether his building is stabilized, how his ownership structure is counted under Good Cause, and what the new lease should say — is the attorney's to make.

Before signing a new lease or taking the building to market, the attorney should review four things: the apartment's regulatory status, the lease itself, the ownership structure, and the proposed notice. Each one feeds the next. The apartment's regulatory status helps determine what rent may legally be charged. The ownership structure decides whether the Good Cause exemption applies. The notice period then has to be measured against the tenancy. Together they determine what a buyer can rely on when they underwrite your building.

Coordinate the lease, the law, and the sale

The real lesson from this consultation is timing. Landlords who plan to sell too often think about legal and lease questions after the listing goes live. That is backwards. A lease signed on the wrong terms, a late or legally defective notice, or an unverified regulatory status can shrink the buyer pool, delay the closing, or cap the price before a single showing happens.

The sequence should be: get the regulatory status verified, confirm the notice period, have an attorney put the renewal together, and only then coordinate the sale strategy against the lease you now hold. Handle it in that order and the lease becomes part of the asset that makes the sale work. Handle it in reverse, and you are signing away options the day you list.

My role was to help this owner understand how the lease, occupancy and rent could affect the buyer pool, marketing strategy and potential sale. The legal determination belongs to a qualified New York landlord-tenant attorney. If you are in the same position, have the paperwork and regulatory status reviewed before committing to a new lease—not after the property is already listed.
