Rent-Stabilized Buildings and DSCR Loans: What NYC Lenders Actually Look For

Key Takeaways

• New York City landlord NOI rose 6.2% citywide between 2023 and 2024 — but buildings with 100% rent-stabilized units saw just 2.4% growth before inflation, a gap that directly squeezes DSCR.
• The 2026 Rent Guidelines Board preliminary vote proposed only 0-2% increases for one-year leases, meaning regulated income growth may not keep pace with rising operating expenses.
• Lenders apply income haircuts to rent-stabilized units, making it harder for mixed-rent buildings to clear the standard 1.25x DSCR threshold — and lending activity for these properties already fell sharply in 2023.
• There are specific, actionable steps — from ancillary revenue to energy efficiency — that can protect NOI and improve financing outcomes even under rent regulation; those are covered in detail below.

Owning a mixed-rent building in New York City has never been simple. Between regulated leases, rising operating costs, Local Law compliance deadlines, and a lending environment that has grown increasingly cautious about stabilized income, the financial math is getting tighter every year. For owners trying to refinance, acquire, or simply benchmark their portfolio, the Debt Service Coverage Ratio is the number that matters most — and rent stabilization is one of the biggest forces pulling it down.

This guide breaks down what the latest 2026 RGB data actually means for mixed-rent building owners, how lenders underwrite stabilized income, and what steps can realistically protect NOI and DSCR in a regulated portfolio. For a deeper look at how lenders analyze these properties, you can calculate your metrics using a standard DSCR formula.

New York City Landlord NOI Rose 6.2% — But Mixed-Rent Buildings Tell a Different Story

The headline from the New York City Rent Guidelines Board's 2026 Income and Expense Study sounds like good news: net operating income for buildings with rent-stabilized units climbed 6.2% between 2023 and 2024. Rental income grew 4.8%, total income rose 4.9%, and expenses increased 4.2%. On paper, that's a healthy spread.

But that citywide figure tells a misleading story for owners of mixed-rent and fully stabilized buildings. As Kenny Burgos, CEO of the New York Apartment Association, stated publicly: “If you take one millionaire and average it with minimum wage earners, you will not get a realistic average of wages, and you can't do that with these buildings either.” The aggregate number is skewed upward by newer developments with market-rate units and large tax abatements — buildings that keep a portion of apartments rent-stabilized in exchange for those tax breaks.

How Rent Stabilization Caps the Income Side of Your DSCR

Stabilized Rents Averaged $1,681 in 2024 — Far Below Market-Rate Units

The numbers make the gap concrete. The RGB's 2026 Income and Expense Study reported that the average rent in a stabilized apartment reached $1,681 in 2024. In Manhattan's core (south of E. 96th St. and W. 110th St.), average stabilized rents were the highest in the city at $2,989 monthly, while Staten Island and the Bronx recorded the lowest averages, at just over $1,110 — figures drawn directly from the RGB's 2026 study.

How HSTPA 2019 Permanently Narrowed the Upside

The Housing Stability and Tenant Protection Act of 2019 fundamentally changed the valuation model for rent-stabilized buildings — and those changes are still reverberating through mixed-rent portfolios today.

HSTPA eliminated high-rent vacancy deregulation, severely capped IAI rent increases, and made preferential rents the permanent legal regulated rent for that tenancy. In practice, this means the upside scenarios that once justified acquiring stabilized buildings — and that lenders once underwrote into their models — are largely gone. Some fully stabilized buildings saw value declines of 20-40% in the years following HSTPA, a reflection of how dramatically the income ceiling had been compressed. For DSCR purposes, that compression is permanent under current law.

What the 2026 RGB Data Actually Means for Your NOI

100% Stabilized Buildings Saw Only 2.4% NOI Growth Before Inflation — vs. 6.2% Citywide

The most telling data point in the RGB's 2026 Income and Expense Study isn't the headline 6.2% — it's what happens when buildings are segmented by the share of stabilized units. Fully rent-stabilized buildings saw NOI rise just 2.4% before inflation. When inflation is factored in, real NOI growth for these buildings was essentially flat or slightly negative.

That 3.8 percentage point gap between fully stabilized buildings and the citywide average represents a structural drag that compounds over time. A building that consistently grows NOI at 2.4% while carrying fixed or adjusting debt service will see its DSCR erode gradually — a slow squeeze that doesn't show up dramatically in any single year but becomes acute when refinancing comes due or when a lender reassesses the loan.

The Bronx: The Only Borough to See NOI Decline

The borough-level data is where the 2026 study gets particularly stark. The Bronx was the only borough to see NOI decline — down 0.1% between 2023 and 2024, according to the RGB's 2026 Income and Expense Study. Neighborhood-level data within the borough showed even sharper deterioration, with areas like Hunts Point and Longwood among the hardest hit, recording NOI declines of more than 13% before inflation per the same study.

These are not outlier buildings experiencing isolated problems. They represent a pattern in high-stabilization, lower-income neighborhoods where operating cost growth has outpaced any income gains allowed under the RGB framework. For owners in these areas, the DSCR math is not just challenging — it may already be negative on a cash-flow basis, which places them in the 9.2% of properties citywide that the RGB classified as financially distressed.

Rising Expenses Are Eating the Gains

Even where NOI grew, the expense side of the ledger is a persistent headwind. The 2026 study showed total expenses rising 4.2% between 2023 and 2024, with property taxes representing the single largest cost category — more than a quarter of all operating expenses. Utilities, insurance, and maintenance costs have also climbed steadily, driven by inflation and Local Law compliance requirements.

The problem for mixed-rent owners is asymmetry: expenses respond to market conditions in real time, while stabilized income responds only to the annual RGB vote — and typically by a smaller margin. That asymmetry slowly compresses the NOI available to cover debt service, regardless of whether a building's income is technically growing. Building owners who aren't actively managing controllable expenses are effectively watching their DSCR shrink without any change in their rent roll.

DSCR Lending on Mixed-Rent Buildings: How Lenders Underwrite Stabilized Income

Why Lenders Haircut Rent-Stabilized Income

DSCR loans evaluate a property's ability to service debt using its own income — not the borrower's personal earnings. That makes them well-suited for investors with complex income structures or multiple properties. But lenders don't simply take the rent roll at face value when stabilized units are involved.

Stabilized income carries regulatory risk that market-rate income doesn't. Because rents are capped by RGB vote, because deregulation pathways were eliminated under HSTPA, and because expense growth consistently outpaces allowable rent increases, lenders apply conservative assumptions — often called a “haircut” — to stabilized income when calculating effective gross income. This effectively lowers the NOI used in the DSCR calculation, even if the actual collected rent is stable. The greater the proportion of stabilized units, the more pronounced the haircut.

The 1.25x DSCR Threshold and Where Mixed-Rent Buildings Fall Short

The standard benchmark for commercial lending is a DSCR of 1.25x or higher. At 1.25x, every $1.00 of debt service is covered by $1.25 of net operating income — a buffer that gives lenders confidence the property can absorb minor income disruptions or expense increases without defaulting.

For mixed-rent buildings where stabilized income is haircut and market-rate income may not fully compensate, clearing 1.25x is genuinely difficult. A building with 70% stabilized occupancy, flat regulated rents, and rising expenses may generate a DSCR of 1.05x to 1.15x — technically above 1.0x but below the threshold most lenders require without compensating factors. Those compensating factors — strong borrower reserves, low LTV, or above-average market-rate performance — aren't always available, particularly for owners who acquired buildings before HSTPA changed the income calculus.

Lending Activity for Stabilized Properties Contracted Sharply in 2023

The challenge isn't just qualifying for a loan — it's finding lenders willing to underwrite these assets at all. Lending activity for rent-stabilized properties in NYC contracted sharply in 2023, with major institutional lenders pulling back significantly and no comparable replacement source stepping in. That contraction has continued to define the financing environment heading into 2026.

For mixed-rent building owners approaching a refinance or acquisition, the practical implication is fewer options, stricter terms, and greater scrutiny on the stabilized portion of the income. Working with lenders who specifically understand the NYC rent-stabilized framework — rather than applying a generic multifamily underwriting model — makes a material difference in what financing ultimately becomes available.

Build DSCR Financing Around Stabilized Cash Flow For A Competitive Edge

The data is clear: mixed-rent buildings in NYC operate in a fundamentally different financial environment than fully market-rate properties. A 2.4% NOI growth rate for fully stabilized buildings, a preliminary 2026 RGB vote proposing increases as low as 0%, a lending market that contracted sharply in 2023, and ongoing expense pressure from taxes, utilities, and compliance — these aren't temporary conditions. They're the structural reality of owning stabilized income-producing property in New York City.

That doesn't mean DSCR financing is out of reach. It means it requires a different approach. Lenders who understand the NYC rent-stabilized framework don't simply apply generic multifamily models — they can structure underwriting around the actual income profile of a mixed-rent building, account for ancillary revenue, and work with the nuances of stabilized versus market-rate income streams. The edge for owners in this space comes from understanding their own numbers precisely — knowing the DSCR on each portion of the portfolio, documenting income cleanly, and engaging lenders who can work within the regulatory landscape rather than around it.
