Do you request seperate application from potential tenant?

[Marcus House]

It just occurred to me this week that after these many years of renting homes that I only request a single application from one adult which means that if 3 adults wish to move into one of my homes the applicant only need to list the landlord history of the person with the strongest landlord track record.

How are other landlords doing applications (in the City) out there?  I said in the City on purse to get a focused set of responses since that is where most of my homes are.
