Anyone keeping a customer database?

[Thomas Neely]

Hello Everyone!

I wanted to ask is there anyone keeping a customer database? Since I have started in real estate investing; any potential renter is keep in an Excel file. So anytime I have someone looking, asking or even mention the word rent I try to gather their information. I only keep basic information such as; name, phone number, email, desired location and notes about that person. The rewards for having this information speaks for it's self. I wanted to get some feedback on you're filing and retention system. Also, I want to know the information that you gather from the potential customer.
