Financing a Rent-Stabilized Apartment Building in Brooklyn After the 2019 Rent Law

Rent stabilized building financing NYC: the anatomy of a post-2019 loan

A loan on a rent-stabilized building is sized like any apartment loan: net operating income divided by a coverage requirement, usually 1.20x to 1.25x, checked against a loan-to-value ceiling. The step-by-step sizing walk-through is in our NYC commercial mortgage guide. What makes the stabilized file different is not the formula; it is the future of the income line, and in June 2019 that future changed.

Before the Housing Stability and Tenant Protection Act, a lender looking at a Brooklyn walk-up could see several ways for income to grow beyond the annual guideline: a vacancy increase every time a tenant left, the chance that a high-rent unit would leave stabilization entirely, and improvement increases with no hard cap. After 14 June 2019, legal rents move only by the Rent Guidelines Board's orders plus capped improvement increases.

The concentration of the problem is in buildings that are almost entirely stabilized: the NYU Furman Center counts about 456,000 rent-stabilized units in 16,600 older buildings that are 90% or more stabilized, 47% of all stabilized units citywide, with a notable presence in Brooklyn neighborhoods such as Flatbush and Midwood.

Brooklyn's older walk-ups and brownstone apartment buildings hold a large share of the city's stabilized units, and of the loans written on them before 2019.

What the 2019 rent law removed from the underwriting

New York State Homes and Community Renewal's own summary of the 2019 law reads like a list of the levers older loans assumed would be available. Four of them matter most for financing.

None of these rules is new news, and lenders priced them in years ago. What is new is that the loans written on the old assumptions are now reaching maturity. A five-, seven- or ten-year loan originated in 2016 to 2019 was often underwritten with some expectation of turnover-driven growth; it is being refinanced in 2026 into a market where that growth is legally gone and, for leases starting between 1 October 2026 and 30 September 2027, the guideline itself is 0%, per the Rent Guidelines Board vote of 25 June 2026.

What the refinance gap actually costs in dollars

Here is the mechanism in numbers. Take an example 24-unit Brooklyn walk-up with an average legal rent of $1,600 in 2019, financed that year at 4.25% on 30-year amortization at a 1.25x coverage test, and refinancing at maturity in 2026 at an example 6.75%. Rents and expenses follow the citywide stabilized trend Ariel Property Advisors reports for 2019 to 2026: rents up 16%, operating expenses up 40%. These are illustrations of the math, not quotes or predictions.

Read the decomposition before blaming the statute. Run the same 2019 income at today's 6.75% and the maximum loan falls to about $2,605,000 on its own: about $825,000 of the roughly $920,000 shrinkage comes from the rate move alone. The income squeeze, rents up 16% while expenses rose 40%, explains the rest. So the 2019 law did not create most of this gap. What the law removed is the way owners used to close a gap like this: a vacancy reset, a deregulated unit, an uncapped renovation increase. Run your own building through the free loan calculator at flat stabilized rents before your first lender call.

Why value and loan size fell separately

Two different numbers fell, for two different reasons. The loan fell because lenders size on coverage, and coverage at 6.75% supports far less debt per dollar of income than coverage at 4.25%. The value fell further, because buyers price stabilized buildings on the income they can see, with no growth they cannot count on, at capitalization rates that now reflect both higher rates and the 2019 law.

Ariel Property Advisors' first-quarter 2026 report puts rent-stabilized pricing about 45% below 2019 per unit, with distressed trades at 70 to 90% discounts to prior values; the Furman Center finds sale prices per square foot for 90% or more stabilized buildings back to roughly their 2011 inflation-adjusted levels, with real median gross income down about 9% from 2019 to 2025.

Brooklyn shows both forces at once. Ariel's first-half 2026 Brooklyn report counts $1.46 billion of multifamily volume across 301 transactions, down 19% in dollars from a year earlier, and describes Brooklyn as holding the city's largest regulated debt pool; the Brooklyn slice of the Pinnacle bankruptcy, 2,692 units, cleared for $212.9 million, about $79,000 a unit.

Lender appetite is uneven too: the Federal Reserve's July 2026 loan officer survey shows banks easing multifamily standards on net, with large banks reporting stronger demand and smaller banks weaker demand, and standards still near the tighter end of their range since 2005. Benchmarks moved against borrowers as well, with the 10-year Treasury at 5.26% on 29 September 2026 per FRED; how that flows into a quote is covered in our guide to commercial mortgage rates.

In a building that is almost entirely stabilized, the rent roll moves only with guideline orders, so the capital plan has to be funded by equity rather than by expected rent increases.

Capital improvements: the invisible third channel

The one income lever the law left open is improvement increases, and since 17 October 2024 the rules have two tiers, per HCR Fact Sheet 26. Tier 1 allows up to $30,000 of individual apartment improvements, collected at 1/168th of cost in buildings of 35 units or fewer, for a maximum increase of $178.57 a month, with written tenant consent if the unit is occupied. Tier 2 allows up to $50,000 for qualifying vacant units with DHCR certification, collected at 1/144th of cost, for a maximum of $347.22 a month. The fact sheet states that the IAI increase is now permanent. Major capital improvements remain capped at 2% a year in collection and are removed after 30 years.

Translate that into loan capacity at the example terms above, where each $1 of added annual income supports about $10.28 of loan at 1.25x coverage. A full Tier 2 renovation adds $4,166.64 of annual rent and roughly $42,800 of loan capacity on a $50,000 spend; a full Tier 1 renovation adds $2,142.84 and about $22,000 of capacity on $30,000. Improvements recover their cost through rent over time, not through refinance proceeds, so they belong in an equity-funded capital plan, not in a plan to close a maturity gap.

What owners can actually control: 4 levers

1. The calendar. Start 18 months before maturity. Measure the gap at today's terms, then talk to your current lender first: an extension or modification on a performing stabilized loan can be worth more than any new quote, because it avoids closing costs and buys time for the free-market units to roll.

2. The registration record. Lenders compare the rent roll with the rents registered with the state. A clean, reconciled DHCR registration history, with preferential rents identified unit by unit, removes the most common reason a stabilized file stalls in underwriting.

3. The gap plan. If the new loan is smaller than the old balance, decide how the difference is funded before the lender asks: cash, a paydown from another asset, a joint venture partner or preferred equity. A bridge loan only makes sense with a credible exit, and on a fully stabilized building that exit is the same coverage test a year later.

4. Matching. Appetite for stabilized buildings differs sharply from desk to desk, and many lenders have narrowed or exited the asset class. Commercial Mortgage Connection works a 750+ lender network with 500K+ programs across all 50 states, with $1B+ originated, every engagement led personally by founder Michael McGovern, and a loan review response within 4 hours. Owners with several buildings can also look at portfolio lending, where a stronger building can support a weaker one inside one facility.

What this page will not tell you: three honest limits

It will not predict the next rent order or rent law. The 2026-27 guideline is 0%; future votes and future legislation are political decisions. A refinance that only works if the next order is generous is a bet, not a plan.

It will not tell you deregulation is coming back. Under current law, high-rent and high-income deregulation is repealed. Any acquisition or refinance model that assumes units will leave stabilization is mispriced. Narrow legal exceptions are a question for a rent regulation attorney, not a lender.

It is written by a brokerage. Commercial Mortgage Connection is paid when loans close, which is exactly why this page tells you that rates, not the statute, made most of the example gap, that an extension from your current lender may beat any refinance, and that cash-out on a deeply stabilized building is rarely there in 2026. CMC gives no legal or tax advice.

Does this apply in your state?

Commercial Mortgage Connection is headquartered in Yonkers, NY and places loans through its 750+ lender network in all 50 states, with its deepest concentration in the New York metropolitan area. The financing mechanics on this page, coverage on in-place income and the maturity gap, apply to any apartment loan anywhere; the general NYC picture is in our NYC commercial mortgage guide.

Rent stabilization is New York law. It covers most older apartment buildings in New York City and, under the Emergency Tenant Protection Act, applies in some other New York municipalities that have opted in, each with its own guidelines board. Other states regulate rents differently or not at all, so confirm the rules for your property's location before you sign a term sheet.

Financing a rent-stabilized apartment building in Brooklyn after the 2019 rent law: FAQ

How did the 2019 rent law change rent stabilized building financing in NYC?

It removed the income growth that many older loans assumed. Since 14 June 2019, owners cannot deregulate apartments for high rent or high income, vacancy and longevity increases are gone, preferential rents cannot be raised to the legal rent at renewal, and improvement increases are capped. Lenders now underwrite stabilized income as growing only by Rent Guidelines Board orders, which for leases starting between 1 October 2026 and 30 September 2027 is 0%.

Can I still deregulate a rent-stabilized apartment in Brooklyn?

Generally, no. The 2019 law repealed the high-rent vacancy and high-income deregulation paths that most owners relied on, so a stabilized unit stays stabilized when a tenant leaves. Narrow exceptions exist and are a question for a rent regulation attorney. For financing purposes, lenders treat stabilized units as permanently stabilized, and so should any purchase or refinance model.

What happens when my pre-2019 loan on a stabilized building matures?

The new loan may be smaller than the old balance. On an example 24-unit Brooklyn walk-up, a 2019 loan of $3,430,000 has about $2,968,600 left in 2026, while today's example terms support about $2,510,300, a gap of roughly $458,000. Options include an extension or modification with the current lender, a refinance with cash or a partner covering the gap, or a sale.

How much does an IAI add to a rent-stabilized building's loan?

Less than it costs. Since 17 October 2024, a Tier 2 improvement of up to $50,000 on a qualifying vacant unit raises rent by at most $347.22 a month in buildings of 35 units or fewer, about $4,167 a year. At example terms where each $1 of income supports about $10.28 of loan, that is roughly $42,800 of loan capacity: improvements pay back through rent over time, not refinance proceeds.

Who lends on rent-stabilized buildings in Brooklyn now?

Community and regional banks, credit unions, agency small-loan programs and, for distressed recapitalizations, debt funds and private lenders. Appetite varies widely: in the Federal Reserve's July 2026 survey, large banks reported stronger multifamily demand while smaller banks reported weaker demand. Because many lenders have narrowed their stabilized exposure, a file shopped across lender types usually finds better proceeds than one shopped at a single bank.
