Underwriting Real Estate & Property Investments

Evaluate acquisition yields, capital structures, and sustainable tenant affordability.

Gross Yield vs. Net Operating Income (NOI)

Gross rental yield provides a rapid benchmark by dividing annual gross rent by property value. Net yield deducts vacancy allowances, property management, insurance, and maintenance to reflect true cash flow.

Mortgage Refinancing Break-Even

Refinancing to secure a lower interest rate entails upfront closing fees and points. Dividing total transaction costs by monthly payment savings reveals the exact months required to break even.

Rent Affordability Guidelines

Traditional underwriting recommends allocating 25% to 35% of monthly gross income toward rent. Factoring existing recurring debt obligations ensures tenants avoid financial distress.
