In your ad, say you will process the emails in the order received and the senders will be notified to fill out an application, if a renter was not chosen from the people ahead of them in line.  

Getting tenants you have chosen yourself, who are people who responded to your ad and rented your unit because they thought it was a fair price, etc., is so much more pleasant.And, as you say, how do you choose which one gets kicked out?

Of course, if you do that, your yield will drop precipitously- in fact, if you tried it in my hometown(New York City,) you'd have a negative cash flow, as the rent rate wouldn't cover the mortgage expenses and taxes.What you've chosen to do, and please correct me if I'm wrong, is purchase B and C residential, and rent to those who are frequently unable to buy a home of their own.
