Miami Developers Sell Condos with Deeded Private Offices

Buying a luxury Miami residence now often includes a deeded private office, a shift from a rare offering to a new development formula. This model provides buyers with two separate titled properties in one transaction, transforming an office from a consumable amenity into a sellable or rentable asset. Fundssociety.com first reported the story.

The concept gained traction in Miami's Brickell financial district as prime office rents surged. The most prominent example is the One Twenty Brickell Residences project by Property Markets Group (PMG). Its 40-story tower contains 467 furnished residences, each paired with a private office featuring its own title deed, private access, and concierge services.

Office Rent Surge in Brickell

The product's emergence aligns with a dramatic transformation in Miami's corporate rental market. According to CBRE data for Q4 2025, Class A office rents in Brickell had risen roughly 74% since 2021, reaching about $102 per square foot annually. In top-tier buildings, rents can hit $225 per square foot, a steep climb from approximately $60 in 2021.

Cushman & Wakefield notes a similar sharp rise, with companies facing renewal proposals between $120 and $130 per square foot, up from pre-pandemic rates of $40 or $50. As a result, prime Miami office occupancy costs now rival those of Manhattan.

Market growth is not uniform, however. CBRE reported a 14.9% vacancy rate across the entire Miami office market for Q2 2026, with an average asking rent of $68.60 per square foot. Colliers reported a 10.8% vacancy rate in Miami-Dade for the same quarter, with a record Class A asking rent of $73.37 per square foot. The data suggests a growing divide between premium spaces and lower-quality offices.

Savills highlights that technology firms, family offices, and financial institutions are driving demand for prime space. This scarcity of high-quality corporate space intersects with luxury housing to create the new product.

From Amenity to Income Asset

Unlike shared amenities, a deeded office can be used, leased, or potentially sold independently. This turns it into a cash-flow generating asset. For a project like One Twenty Brickell, a single transaction incorporates a second asset, shifting an investor's focus to the office's value and income potential.

Potential Income and Expansion

The model's commercial pitch includes significant income potential. Developers indicate an office can represent up to $80,000 in additional annual value beyond the apartment's return. This is a gross potential income; net yield depends on purchase price, operating costs, taxes, and effective rent.

The formula is expanding geographically. It is being replicated in Wynwood, at projects like Twenty Sixth & 2nd by PMG and LNDMRK Development, which includes 233 residences and 122 deeded offices. Downtown Miami is also incorporating similar high-end projects. This expansion will test if demand is structural or unique to Brickell.

The model caters to a post-hybrid work environment where companies may need less space but pay more for premium, well-located offices. It targets entrepreneurs, independent professionals, and small firms seeking a prestigious address.

Strong International Buyer Demand

The product finds a natural market with international buyers, particularly from Latin America. Data indicates Latin American buyers represent 86% of new construction purchasers in Miami. According to MIAMI REALTORS, foreign buyers purchased roughly $4.4 billion in South Florida residential properties in 2025, up from $3.1 billion in 2024, acquiring about 5,300 properties.

International participation is especially strong in new housing. A study of 9,115 units across 37 developments found international buyers accounted for 49% of sales in new construction, pre-sales, and conversions over the 18 months ending June 2025. This demand explains why developers design products addressing wealth planning and business needs alongside housing.
