Data Center Investment in Boston

Boston's data center market is tight. Power constraints and permitting headaches keep supply in check while AI workloads drive demand through the roof. Cap rates compressed 75-100 bps over the past 18 months. Hyperscale deals are scarce - most inventory is enterprise colocation with 5-15MW capacities. The city's biotech boom creates unique demand patterns. Labs need low-latency connections but don't consume massive power like crypto or AI training. Edge facilities are popping up in suburbs to serve this market.

Market Context

Cap Rate Range

4.75%-6.25% for stabilized facilities, premium colocation trades below 5%

Current Vacancy

Sub-5% market-wide, practically zero for quality facilities with available power

Rent Trend

Colocation rates up 15-20% YoY, wholesale power trending $85-110 per kW monthly

Absorption

Strong absorption of 35-40MW annually, constrained by new supply delivery

Price Per Unit Trend

Price per MW hitting $8-12M for turnkey facilities, land values doubling in power-rich zones

Transaction Volume

$1.2B in trailing 12 months, up 40% from 2024 despite limited inventory

Carrier neutrality and fiber diversity drive colocation premiums

Data to Include

On-net carrier list, fiber entrance facility details, dark fiber availability, cross-connect revenue per cabinet

Tenant Concentration Risk

Single-tenant risk is higher in Boston's specialized market

Data to Include

Tenant roster by revenue percentage, lease expiration schedule, credit ratings, expansion/contraction rights in leases

Permitting and Expansion Rights

Future capacity expansion can double asset value in tight market

Data to Include

Current zoning approvals, utility capacity reservations, environmental permits, construction timeline and cost estimates

Operating Expense Breakdown

Power and cooling dominate opex - show efficiency trends

Data to Include

3-year utility cost history, PUE improvement initiatives, maintenance contracts, staff count and costs per MW managed

Investment Outlook

Short Term

Supply shortage continues through 2027. Existing facilities see 10-15% rent growth. New construction costs hit $12-15M per MW. Permitting remains 18-month+ process.

Medium Term

Power grid improvements by 2028-2029 may ease constraints. Edge computing expansion accelerates. Biotech sector consolidation could impact specialized facilities. Climate regulations may require efficiency upgrades.

Long Term

AI workload growth fundamentally changes power requirements. Quantum computing facilities emerge as new asset class. Sea level rise impacts coastal facilities. Grid modernization enables renewable power integration.

Buyer Profile

REITs dominate acquisition activity above $50M. Private equity targets value-add opportunities in 2010-2015 vintage. Hyperscalers increasingly build vs buy. Foreign capital active in sale-leaseback structures.
