Our Strategy

The Opportunity

Acquiring Assets at a Discount

Supply constraints, elevated interest rates, and a shallow investor pool driven by regulatory uncertainty have created an opportunity to acquire extremely attractive assets at prices near record lows and at steep discounts to replacement cost.

Acquiring exceptional multifamily assets in the nation's premier real estate market

What We Do

AXIM acquires newly constructed, fully stabilized, high cash flow generating multifamily real estate assets participating in the 421-a property tax exemption program in New York City. These assets represent a special and often misunderstood class of property with unique structural advantages unavailable in any other market.

Our Edge

AXIM has longstanding industry relationships that enable off-market origination and proprietary deal flow. Our team employs a nuanced financial analysis and due diligence process to evaluate current and future property values, cash flows, and regulatory compliance — with a clear guiding principle: focus on risk before return.

We implement institutional accounting, property management, and asset management processes while engaging tested, industry-leading service providers throughout the hold period.

Market Opportunity

Why New York City multifamily outperforms every other market

Consistent Long-Term Rent Growth

Over the past decade, per square foot rents have grown at a 5-year CAGR of 6.5% in Manhattan, 5.5% in Brooklyn, and 6.8% in Northwest Queens — outperforming every other major U.S. market. NYC has delivered superior rent growth regardless of political leadership or economic cycle.

Structurally Constrained Supply

The expiration of the 421-a program in 2022 eliminated the primary incentive for new multifamily development. New housing permits have fallen to their lowest level in over a decade, creating permanent supply constraints that will amplify future rent growth cycles.

Demographic Tailwinds

NYC's largest demographic cohort — 25 to 44 year olds representing 31% of residents — is increasingly choosing to rent rather than buy due to elevated homeownership costs. With 20 ranked universities and 78% student retention, NYC continues to attract the highly educated workforce that drives durable rental demand.

A Generational Buying Opportunity

Elevated interest rates, 421-a rent restrictions, and a shallow investor pool driven by regulatory headlines have created an opportunity to acquire extremely attractive assets at prices near record lows and at steep discounts to replacement cost — with a forced seller base and limited competition.

The 421-a Program

A unique and time-limited investment window

The 421-a program grants newly constructed multifamily buildings a long-duration property tax exemption in exchange for units being temporarily subject to rent stabilization. At the end of the benefit period, rent stabilization restrictions are lifted and units become fully deregulated market-rate apartments — creating a defined, statutory path to value creation unavailable in any other asset class.

Financial Benefits

Why These Assets Outperform

Long Duration Tax Exemption

Accelerates return of capital from cash flow and helps quickly retire invested capital basis.

Attractive to Lenders

Highly predictable cash flows and near-zero vacancy rates unlock immediately accretive financing terms.

Market Rent Participation

Over 70% of units in 421-a (16) buildings are market rate, allowing buildings to capitalize on rent growth during the tax exemption period.

Good Cause Eviction Exemption

A 30-year carve-out from 2024 rent restrictions on market rate units in buildings built post-2008, which includes nearly all 421-a buildings.

Value Creation

Our Process

Deal Sourcing

We contact building owners directly using our proprietary database of 421-a assets, while also originating leads through longstanding relationships with the NYC brokerage community.

Skeptical Underwriting

We employ a nuanced proprietary financial analysis and due diligence process to evaluate current and future property values, cash flows, and regulatory compliance.

Disciplined Management

We implement institutional accounting, property management, and asset management processes while engaging tested, industry-leading service providers.

Maximize Value

We constantly evaluate operational performance and broader market conditions to best time exits and maximize sale proceeds for our investors.
