There are 4 basic ways to screen commercial tenants. I personally call it SFRC
Strategic – Ask basic question concerning their mission, vision. Where they seek to be in 5, 10 years. Current profile of customers/clients, how they market/advertise, and the busiest time of day and seasons for businesses. Are they seasonal and earn 50% or more of their revenue during those times? What are their peak times of doing business during a normal work day? What are their current and projected business hours
Financial – Request P&Ls, Cash Flow statements from the past 2 years. If they can’t won’t provide, then that’s a red flag.
Reputational – Search online reviews like Yelp and others. Review their blog, website, social media. How do they present themselves to clients, customers and to the world. Also check BBB and check the county course records for previous and current lawsuits, judgments, etc.
Client/Customer Experience – Send in secret shoppers at different times to observer their services, professionalism, etc at their current location. Also do drivebys of their current business to get a vibe of client, where the neighborhood their currently in.
I hope this helps. I"ll be reposing this in other forums as well. Feel free to PM if you have questions. Houston based here!
