Building a $2.8B Empire with Jay Roberts | 10X Money Talks
TL;DR
Jay Roberts, founder of Prosper Group, explains how he built a $2.8B luxury development portfolio in Miami by leveraging Florida's unique buyer deposit financing laws, targeting waterfront trophy assets in rapidly growing Brickell, and strategically pivoting to commercial office space to capture higher yields.
💵 The Florida Deposit Financing Model 3 insights
Use buyer deposits to fund construction
Florida law allows developers to use 90% of buyer deposits to pay for construction after posting a 2% bond, unlike California or New York where equity must cover all costs, significantly reducing capital requirements and boosting ROI.
$800 hard cost versus $2,000 sale price
Roberts builds at $800 per square foot with $1,600 all-in costs including land, selling luxury units at $2,000 per square foot to achieve a 20% profit margin on trophy assets.
Waterfront premium as margin of safety
Identical construction costs apply to waterfront and inland properties, but buyers pay premiums exceeding $2,000 per square foot for water access versus $1,600 off-water, creating a valuation cushion against market corrections.
🏢 Strategic Asset Allocation 2 insights
Pivot to commercial office for higher yields
Roberts converted a planned residential building to 100,000 square feet of Class A office after seeing comparable rents reach $250 per square foot, generating an additional $250 million in revenue at 40% margins by selling the leased asset at a 5.5% cap rate.
Brickell's Wall Street transformation
Major financial institutions including Citadel, Blackstone, and Ken Griffin are establishing headquarters in Brickell, driving demand for luxury housing with 140 new buildings currently under construction in South Florida.
📊 Capital Strategy & Market Dynamics 3 insights
Off-market deal sourcing
Roberts personally deploys hard money to secure off-market sites before bringing in capital partners like fourth-generation Belgian developer Verselize, avoiding competitive bidding wars that inflate land costs.
Florida population growth fundamentals
Florida is projected to add 5.1 million residents over the next 25 years compared to New York's 819,000, creating fundamental demand that supports new supply despite aggressive construction activity.
International capital attraction
Weak European GDP growth (1.5%) versus US growth (5% in Q4) is driving foreign investment from European family offices seeking higher yields in Florida's expanding markets.
Bottom Line
Secure off-market waterfront trophy assets in high-growth migration corridors, leverage state-specific deposit financing laws to minimize equity requirements, and maintain flexibility to pivot between residential and commercial based on real-time rent data.
