Timing Advantage: Yardi Matrix forecasts fewer completions in 2026 than net absorption, suggesting the oversupply cycle turns before this project delivers in 2029–2030.

Reworked Financial Analysis

Original Pro Forma vs. MAKR Analysis

The original offering memo significantly underestimates total development costs. MAKR has reworked the numbers based on current Miami market data and comparable projects.

Line ItemOriginal Pro FormaMAKR Reworked (Base)MAKR Reworked (Conservative)
Land Value$21,000,000$21,900,000$21,900,000
Construction ($350/SF vs $445/SF)$118,720,700$150,900,000$165,000,000
Smart Building Technology--$6,500,000$9,800,000
Soft Costs$14,433,642$34,000,000$41,600,000
Financing Costs$14,026,377$17,700,000$18,000,000
Contingency (7.5%)--$11,300,000$12,400,000
Total$178,072,340$242,300,000$268,700,000

Key Adjustments:

  1. Construction costs: $350/SF is below market for a 48-story Miami tower. Current GC pricing for 40+ story residential is $400–$500/SF. We use $445/SF midpoint.
  2. Insurance: Original $3.27M/yr is unrealistic. Florida premiums are 181% above national average. Budget $5–7.4M/yr.
  3. Property taxes: Original $420K/yr appears miscalculated even with Live Local Act exemption. Realistic range: $1–3M/yr.
  4. Smart building technology: Not included in original. Budget $5–10M for institutional-grade smart building.
  5. Contingency: Not included in original. 7.5% contingency is standard for 48-story Miami tower.

Smart Building Technology

PureBrain Integration Opportunity

This project represents a showcase opportunity for MAKR's PureBrain technology platform, positioning the building as Miami's first AI-native rental tower.

Technology Budget

Smart locks, thermostats, sensors$1,450 – $2,850$619K – $1.2M
Building Management System (BMS)--$1.7M – $3.4M

AI layer (PureBrain)--$1.0M – $2.65M
Total$11K – $16K/unit$4.7M – $9.8M

Revenue Impact

Strategic Value

Beyond rental premiums, an AI-native building serves as:

  1. Proof of concept for PureBrain building technology
  2. Sales tool for other development partnerships
  3. Operational efficiency platform (energy savings, predictive maintenance)
  4. Data asset for property management optimization
Section 10

Risk Assessment

Risk FactorSeverityMitigation
Construction cost overrun ($350/SF pro forma vs. $400–500/SF reality) High Independent GC estimate required. GMP contract. 7.5% contingency budgeted.
Miami rental oversupply (45K units in 3 years) Moderate-High 2029–2030 delivery catches cycle turn. Break-even at 55% occupancy.
Insurance escalation (FL premiums 181% above national avg) High Stress-tested at $5–6M/yr. New code-compliant tower performs better than older stock.
Sponsor experience gap Moderate-High Addressed by MAKR co-ownership + GFI consortium + experienced GC.
Entitlement risk (48-story height) Moderate Confirmed by zoning code and neighboring 47-story approval at 1502 NE 1st Ave.
Interest rate environment Moderate 7–8% construction rates already assumed. Refinance risk at stabilization.
Hurricane / climate Moderate Post-Andrew HVHZ code compliance. Business interruption insurance.
2026 tariff escalation (25% on steel) Moderate Budgeted at 2026 pricing. GMP contract transfers risk to GC.
