*There is no assurance that Rich Uncles NNN REIT, Inc. will be able to meet the stated objectives. Remaining lease terms for our tenants are on average between 4 to 13 years. Broad geographical diversification helps prevent a single region’s economy from significantly affecting our REIT performance. Our “Triple Net” Lease structure strategy provides that our tenants are responsible for taxes, insurance, and maintenance. We limit purchase debt to 50% of the portfolio value, compared to 75% or 80% purchase debt strategies employed by many non - listed REITs. We acquire single - tenant properties that are currently leased by creditworthy tenants. With our diversified property portfolio, the risk of tenant default is spread across our entire REIT. Our Investment Strategy * Guided by our founders’ combined century of investment experience, our portfolio of commercial real estate is strictly vetted through a comprehensive purchasing strategy.
