Advanced Financing Structures and Their Impact on Returns

Bridge loans are short-term (12-36 month) floating-rate loans designed for transitional properties that do not qualify for permanent financing. They typically offer higher LTV (75-80% of purchase plus 100% of renovation costs), higher interest rates (SOFR + 300-500bps), interest-only payments during the term, and extension options for 6-12 months. The underwriting implication: interest-only payments improve cash flow during renovation, but the exit strategy must be clearly defined—refinance into permanent debt or sell. If the property does not stabilize on schedule, the bridge loan maturity becomes a forced decision point. Model the bridge-to-permanent refinance explicitly, including the refinance qualification requirements (DSCR, LTV, NOI thresholds the permanent lender will require).

When senior debt LTV is insufficient, sponsors use mezzanine debt (a second-position loan) or preferred equity (equity with priority returns) to fill the capital stack gap. Mezzanine debt typically carries rates of 10-15% and is secured by a pledge of the borrowing entity's ownership interests. Preferred equity receives a fixed preferred return (8-12%) before common equity receives any distributions, and may include participation in upside. Both increase leverage and boost common equity IRR when the deal performs well—but they also increase risk by adding fixed obligations. The underwriter must model the full capital stack waterfall: senior debt service first, then mezzanine debt service, then preferred equity return, then common equity distributions.

Seller financing occurs when the seller acts as the lender, carrying back a note for part of the purchase price. Common structures include: full seller carryback (seller finances the entire purchase), second-position seller note (behind conventional first mortgage), and seller participation (seller takes a share of future profits in exchange for below-market financing). Seller financing can dramatically improve deal economics by reducing equity requirements, eliminating bank qualification hurdles, and offering more flexible terms. When modeling seller financing, include: the note's interest rate, amortization schedule, balloon payment timing, and any participation triggers. The key risk is the balloon payment—if you cannot refinance when the seller note matures, you face default.
